Kubernetes and Cloud Native Associate KCNA Practice Test 60
Question 590
An operator notices this unresolved gap: A YAML Deployment is modified but the existing cluster still runs an old image version. What consequence BEST explains the need to address it?
Manual per-node tweaks drift from declarative manifests and audit history
Editing local YAML without submitting it leaves running state unchanged
Unbounded allocations in one team can exhaust shared cluster capacity
Missing resource conventions can lead to accidental resource starvation
Explanation
Correct Answer
B:
Editing local YAML without submitting it leaves running state unchanged. This is the direct concern in the stated scenario because kubectl apply submits desired object configuration for controller reconciliation. The matching mitigation is to apply the declarative manifest and inspect the resulting rollout. Successful verification would show that the Deployment generation and running image reflect the updated manifest.
Incorrect Answers
A:
Cluster management is expressed primarily through versioned API objects. That explains the warning “Manual per-node tweaks drift from declarative manifests and audit history”; this case instead concerns “Editing local YAML without submitting it leaves running state unchanged”. Kubectl apply submits desired object configuration for controller reconciliation.
C:
Namespace quotas constrain aggregate API resource consumption. That explains the warning “Unbounded allocations in one team can exhaust shared cluster capacity”; this case instead concerns “Editing local YAML without submitting it leaves running state unchanged”. Kubectl apply submits desired object configuration for controller reconciliation.
D:
LimitRanges can provide default constraints to containers in a namespace. That explains the warning “Missing resource conventions can lead to accidental resource starvation”; this case instead concerns “Editing local YAML without submitting it leaves running state unchanged”. Kubectl apply submits desired object configuration for controller reconciliation.
Question 591
For this Kubernetes condition, A Pod is Pending because required affinity matches no current node. The proposed approach is: Inspect failed-scheduling conditions and compare affinity with node labels. Which technical principle BEST supports that choice?
Preferred scheduling preferences rank candidates without making placement mandatory
Affinity decisions depend on consistent node topology-key labels
Unsatisfied hard node affinity prevents scheduler placement despite free resources
Requests influence scheduling while limits bound container memory consumption
Explanation
Correct Answer
C:
Unsatisfied hard node affinity prevents scheduler placement despite free resources. That principle directly explains the selected remediation, inspect failed-scheduling conditions and compare affinity with node labels, for this case. Without the distinction, deleting unrelated running Pods cannot create a matching node label. The expected confirmation is that after a correct node label or policy change the Pod becomes scheduled.
Incorrect Answers
A:
Preferred scheduling preferences rank candidates without making placement mandatory. The operation “Preferred scheduling preferences rank candidates without making placement mandatory” does not address the particular Kubernetes requirement “Unsatisfied hard node affinity prevents scheduler placement despite free resources”.
B:
Affinity decisions depend on consistent node topology-key labels. The operation “Affinity decisions depend on consistent node topology-key labels” does not address the particular Kubernetes requirement “Unsatisfied hard node affinity prevents scheduler placement despite free resources”.
D:
Requests influence scheduling while limits bound container memory consumption. The operation “Requests influence scheduling while limits bound container memory consumption” does not address the particular Kubernetes requirement “Unsatisfied hard node affinity prevents scheduler placement despite free resources”.
Question 592
A platform engineer recommends: Apply a suitable LimitRange with documented defaults and boundaries. The original problem is: New Pod manifests omit memory requests, causing unpredictable resource admission. Which concept explains the remedy?
The default kubectl namespace view excludes resources in other namespaces
Namespaced API queries avoid mixing identical resource names from other teams
Cordon marks a node unschedulable without directly evicting running Pods
LimitRanges can provide default constraints to containers in a namespace
Explanation
Correct Answer
D:
LimitRanges can provide default constraints to containers in a namespace. That principle directly explains the selected remediation, apply a suitable LimitRange with documented defaults and boundaries, for this case. Without the distinction, missing resource conventions can lead to accidental resource starvation. The expected confirmation is that new Pods receive expected admission defaults or clear validation errors.
Incorrect Answers
A:
The default kubectl namespace view excludes resources in other namespaces. The operation “The default kubectl namespace view excludes resources in other namespaces” does not address the particular Kubernetes requirement “LimitRanges can provide default constraints to containers in a namespace”.
B:
Namespaced API queries avoid mixing identical resource names from other teams. The operation “Namespaced API queries avoid mixing identical resource names from other teams” does not address the particular Kubernetes requirement “LimitRanges can provide default constraints to containers in a namespace”.
C:
Cordon marks a node unschedulable without directly evicting running Pods. The operation “Cordon marks a node unschedulable without directly evicting running Pods” does not address the particular Kubernetes requirement “LimitRanges can provide default constraints to containers in a namespace”.
Question 593
Consider this Kubernetes scenario: Deleting a Deployment leaves owned child resources unexpectedly pending deletion. What is the BEST next action?
Inspect owner references and finalizers before forcing orphan cleanup
Place tightly coupled containers in one Pod with explicit volume sharing
Update the desired-state manifest or controlling resource instead of manual drift
Use a DaemonSet with suitable node selectors and tolerations
Explanation
Correct Answer
A:
Inspect owner references and finalizers before forcing orphan cleanup. This is appropriate for the described asset and control gap because kubernetes garbage collection uses owner references while finalizers can delay removal. If the issue is left untreated, blindly deleting finalizers may bypass resource cleanup responsibilities. An assessor can verify remediation when an approved cleanup clears blockers and owned resources are removed safely.
Incorrect Answers
B:
Place tightly coupled containers in one Pod with explicit volume sharing. The operation “Place tightly coupled containers in one Pod with explicit volume sharing” does not address the particular Kubernetes requirement “Inspect owner references and finalizers before forcing orphan cleanup”.
C:
Update the desired-state manifest or controlling resource instead of manual drift. The operation “Update the desired-state manifest or controlling resource instead of manual drift” does not address the particular Kubernetes requirement “Inspect owner references and finalizers before forcing orphan cleanup”.
D:
Use a DaemonSet with suitable node selectors and tolerations. The operation “Use a DaemonSet with suitable node selectors and tolerations” does not address the particular Kubernetes requirement “Inspect owner references and finalizers before forcing orphan cleanup”.
Question 594
In a Kubernetes environment this issue remains open: A new container cannot pull its image after a registry authentication rotation. Which failure is the MOST direct consequence?
Deleting failing Pods without changing the invalid flag repeats CrashLoopBackOff
Assuming a completed image push means runtime readiness conceals deployment defects
Relying on Pod phase alone can conceal saturation or failed dependencies
Explanation
Correct Answer
B:
Changing liveness probes cannot resolve registry authorization failures. This is the direct concern in the stated scenario because container retrieval requires valid credentials before the process can launch. The matching mitigation is to inspect pull events and verify scoped imagePullSecret references and registry access. Successful verification would show that the image download succeeds after correcting the registered pull credential.
Incorrect Answers
A:
Startup failures often appear in terminated container output and process configuration. That explains the warning “Deleting failing Pods without changing the invalid flag repeats CrashLoopBackOff”; this case instead concerns “Changing liveness probes cannot resolve registry authorization failures”. Container retrieval requires valid credentials before the process can launch.
C:
Delivery debugging begins with resource status and failure conditions. That explains the warning “Assuming a completed image push means runtime readiness conceals deployment defects”; this case instead concerns “Changing liveness probes cannot resolve registry authorization failures”. Container retrieval requires valid credentials before the process can launch.
D:
A Running Pod indicates process state rather than end-to-end service success. That explains the warning “Relying on Pod phase alone can conceal saturation or failed dependencies”; this case instead concerns “Changing liveness probes cannot resolve registry authorization failures”. Container retrieval requires valid credentials before the process can launch.
Question 595
The team has not corrected this condition: A payment processing service needs a graceful shutdown during rolling replacement. Which risk is MOST relevant?
Rebuilding from an unpinned branch during promotion can change program behavior
Switching every user at once makes regression impact harder to contain
Immediate process termination can interrupt in-flight work or cause duplicate payment calls
Counting only healthy Pods can miss application-level errors after a release
Explanation
Correct Answer
C:
Immediate process termination can interrupt in-flight work or cause duplicate payment calls. This is the direct concern in the stated scenario because kubernetes sends shutdown signals and allows bounded cleanup before forced stop. The matching mitigation is to configure termination handling and adequate termination grace period. Successful verification would show that an update drains active requests before the previous Pod is removed.
Incorrect Answers
A:
Artifact promotion preserves the same tested application bits across stages. That explains the warning “Rebuilding from an unpinned branch during promotion can change program behavior”; this case instead concerns “Immediate process termination can interrupt in-flight work or cause duplicate payment calls”. Kubernetes sends shutdown signals and allows bounded cleanup before forced stop.
B:
Canary delivery limits the blast radius of new behavior for evaluation. That explains the warning “Switching every user at once makes regression impact harder to contain”; this case instead concerns “Immediate process termination can interrupt in-flight work or cause duplicate payment calls”. Kubernetes sends shutdown signals and allows bounded cleanup before forced stop.
D:
Delivery gates use measured user outcomes to decide whether to continue rollout. That explains the warning “Counting only healthy Pods can miss application-level errors after a release”; this case instead concerns “Immediate process termination can interrupt in-flight work or cause duplicate payment calls”. Kubernetes sends shutdown signals and allows bounded cleanup before forced stop.
Question 596
An operator notices this unresolved gap: A namespace administrator wants to ensure a particular app never receives host-network access. What consequence BEST explains the need to address it?
Using a cluster-admin binding for basic monitoring creates excessive authority
Static shared admin credentials can let one app reach unrelated cloud resources
A default open Pod network can permit cross-team connections despite namespace separation
An app with unrestricted host networking can expose host-level network services
Explanation
Correct Answer
D:
An app with unrestricted host networking can expose host-level network services. This is the direct concern in the stated scenario because host networking increases the impact of insecure workloads and bypasses Pod isolation assumptions. The matching mitigation is to set admission guardrails and validate workload Pod specifications against policy. Successful verification would show that a negative admission test blocks hostNetwork on the target namespace.
Incorrect Answers
A:
Kubernetes RBAC grants explicit verbs on resource types to bound subjects. That explains the warning “Using a cluster-admin binding for basic monitoring creates excessive authority”; this case instead concerns “An app with unrestricted host networking can expose host-level network services”. Host networking increases the impact of insecure workloads and bypasses Pod isolation assumptions.
B:
Workload identity binds a Pod or service account to defined cloud authority. That explains the warning “Static shared admin credentials can let one app reach unrelated cloud resources”; this case instead concerns “An app with unrestricted host networking can expose host-level network services”. Host networking increases the impact of insecure workloads and bypasses Pod isolation assumptions.
C:
Namespaces partition resource names and policy scope but are not automatic network firewalls. That explains the warning “A default open Pod network can permit cross-team connections despite namespace separation”; this case instead concerns “An app with unrestricted host networking can expose host-level network services”. Host networking increases the impact of insecure workloads and bypasses Pod isolation assumptions.
Question 597
A Kubernetes platform team observes this situation: A service account should authenticate only the scheduled batch tasks it owns. Which action BEST addresses the requirement?
Create a dedicated service account and bind the narrow required permissions
Uncordon the validated node and monitor its health and workload placements
Manage Kubernetes manifests in version control with reviewed promotion
Apply a ResourceQuota appropriate to the namespace and its workload needs
Explanation
Correct Answer
A:
Create a dedicated service account and bind the narrow required permissions. This is appropriate for the described asset and control gap because kubernetes service accounts provide workload identity within API authorization. If the issue is left untreated, sharing a privileged default service account expands compromise consequences. An assessor can verify remediation when the Job reads permitted resources while unrelated API updates are forbidden.
Incorrect Answers
B:
Uncordon the validated node and monitor its health and workload placements. The operation “Uncordon the validated node and monitor its health and workload placements” does not address the particular Kubernetes requirement “Create a dedicated service account and bind the narrow required permissions”.
C:
Manage Kubernetes manifests in version control with reviewed promotion. The operation “Manage Kubernetes manifests in version control with reviewed promotion” does not address the particular Kubernetes requirement “Create a dedicated service account and bind the narrow required permissions”.
D:
Apply a ResourceQuota appropriate to the namespace and its workload needs. The operation “Apply a ResourceQuota appropriate to the namespace and its workload needs” does not address the particular Kubernetes requirement “Create a dedicated service account and bind the narrow required permissions”.
Question 598
The team has not corrected this condition: A scheduler assigns Pods based on requests but users expect it to react to live utilization by itself. Which risk is MOST relevant?
Selecting a node label does not necessarily colocate with the intended application
Leaving workloads to drift can create hotspots after initial scheduling
Using a hard requirement can leave the service Pending during capacity shortage
An undefined topology domain can lead to unexpected scheduling outcomes
Explanation
Correct Answer
B:
Leaving workloads to drift can create hotspots after initial scheduling. This is the direct concern in the stated scenario because default placement is not continuous live-CPU load balancing among healthy nodes. The matching mitigation is to use suitable autoscaling or descheduling components rather than assuming automatic migrations. Successful verification would show that measured autoscaling changes intended replica capacity without forced random migrations.
Incorrect Answers
A:
Pod affinity can make placements depend on other matching Pods in topology domains. That explains the warning “Selecting a node label does not necessarily colocate with the intended application”; this case instead concerns “Leaving workloads to drift can create hotspots after initial scheduling”. Default placement is not continuous live-CPU load balancing among healthy nodes.
C:
Preferred scheduling preferences rank candidates without making placement mandatory. That explains the warning “Using a hard requirement can leave the service Pending during capacity shortage”; this case instead concerns “Leaving workloads to drift can create hotspots after initial scheduling”. Default placement is not continuous live-CPU load balancing among healthy nodes.
D:
Affinity decisions depend on consistent node topology-key labels. That explains the warning “An undefined topology domain can lead to unexpected scheduling outcomes”; this case instead concerns “Leaving workloads to drift can create hotspots after initial scheduling”. Default placement is not continuous live-CPU load balancing among healthy nodes.
Question 599
Consider this Kubernetes scenario: A team claims 99.9 percent availability but has not defined what users experience. What is the BEST next action?
Instrument with OpenTelemetry-compatible signals and a governed collection pipeline
Collect metrics, structured logs, and distributed traces with correlation identifiers
Define a user-focused service level indicator and an objective with a measurement window
Review discovery labels, target endpoints, and scrape configuration
Explanation
Correct Answer
C:
Define a user-focused service level indicator and an objective with a measurement window. This is appropriate for the described asset and control gap because sLIs quantify observable service behavior while SLOs express a reliability target. If the issue is left untreated, counting Pod uptime alone can misrepresent successful user request outcomes. An assessor can verify remediation when a documented availability SLI drives a clear SLO and measured error budget.
Incorrect Answers
A:
Instrument with OpenTelemetry-compatible signals and a governed collection pipeline. The operation “Instrument with OpenTelemetry-compatible signals and a governed collection pipeline” does not address the particular Kubernetes requirement “Define a user-focused service level indicator and an objective with a measurement window”.
B:
Collect metrics, structured logs, and distributed traces with correlation identifiers. The operation “Collect metrics, structured logs, and distributed traces with correlation identifiers” does not address the particular Kubernetes requirement “Define a user-focused service level indicator and an objective with a measurement window”.
D:
Review discovery labels, target endpoints, and scrape configuration. The operation “Review discovery labels, target endpoints, and scrape configuration” does not address the particular Kubernetes requirement “Define a user-focused service level indicator and an objective with a measurement window”.
Question 600
A team implemented the proposed remedy for this problem: A dashboard needs extra human-readable incident ownership attached to workloads. Which evidence BEST shows it works?
Each eligible node reports exactly one healthy agent Pod
The proper service.namespace DNS name resolves to its expected ClusterIP
The companion containers communicate over localhost and see the intended shared files
The ownership annotation changes without modifying the selected backend set
Explanation
Correct Answer
D:
The ownership annotation changes without modifying the selected backend set. This is stronger than observing a saved configuration because it tests the actual outcome of store nonidentifying descriptive metadata in annotations rather than selectors. The underlying principle is that annotations hold auxiliary object information that need not identify selection groups. The original risk was that using mutable ticket text as a Service selector can disconnect endpoints.
Incorrect Answers
A:
DaemonSets maintain a designated Pod copy on every selected node. The observation “Each eligible node reports exactly one healthy agent Pod” would validate that property, rather than the required “The ownership annotation changes without modifying the selected backend set”. Annotations hold auxiliary object information that need not identify selection groups.
B:
Cluster DNS maps Kubernetes Service names to records within configured search domains. The observation “The proper service.namespace DNS name resolves to its expected ClusterIP” would validate that property, rather than the required “The ownership annotation changes without modifying the selected backend set”. Annotations hold auxiliary object information that need not identify selection groups.
C:
A Pod is the smallest deployable unit with shared network namespace and volumes. The observation “The companion containers communicate over localhost and see the intended shared files” would validate that property, rather than the required “The ownership annotation changes without modifying the selected backend set”. Annotations hold auxiliary object information that need not identify selection groups.

The most complete solution for passing with Linux Foundation certification KCNA exam practice test questions and answers, study guide, training course.
Kubernetes and Cloud Native Associate (KCNA)
The Kubernetes and Cloud Native Associate (KCNA) is a current beginner-level certification from the Linux Foundation and CNCF. As of October 2026, the Linux Foundation lists a 90-minute, online proctored, multiple-choice exam with no prerequisites.
The blueprint places 44% on Kubernetes Fundamentals, 28% on Container Orchestration, 16% on Cloud Native Application Delivery, and 12% on Cloud Native Architecture. That breadth makes KCNA a map of the ecosystem rather than a command-line administrator exam.
KCNA is a useful starting point before deeper credentials such as CKA or the security-focused KCSA. The best preparation builds a clear mental model of why cloud-native systems use containers, declarative APIs, orchestration, observability, and automated delivery.
Understand containers before trying to understand orchestration
The difference between a container and a Pod is foundational. The explanation of Pods and containers helps clarify that Kubernetes schedules Pods, which can contain one or more tightly coupled containers sharing parts of their runtime context.
Review images, registries, container runtime concepts, isolation, and why immutable application packaging improves repeatability. Then ask what remains unsolved when hundreds of containers must be placed, restarted, networked, and updated.
That gap is where orchestration begins. Kubernetes exists because individual container tools do not by themselves provide cluster-wide desired-state management.
Compare local container execution with a clustered deployment. The discussion of Kubernetes and Docker can help separate image and runtime concerns from orchestration concerns. A container runtime starts workloads on a machine; Kubernetes adds an API and control system for deciding where workloads should run and continuously reconciling them across a cluster.
Also connect containers to portability without overstating it. Packaging dependencies improves consistency, but the workload still depends on CPU architecture, kernel capabilities, storage, networking, identity, and external services. Cloud-native design manages those dependencies explicitly instead of assuming an image makes infrastructure irrelevant.
Kubernetes control loops turn desired state into running systems
Use cluster anatomy to understand how the API server, etcd, controller manager, scheduler, and kubelet cooperate. The important idea is reconciliation: controllers continually compare desired state with observed state and act to reduce the difference.
Create a Deployment, then delete one Pod. Watching the controller restore the replica count makes self-healing concrete. Scale the Deployment and observe that the user changes desired state while Kubernetes determines the necessary actions.
This mental model also explains why direct manual changes to managed resources can be temporary. The controller will continue enforcing the declared intent.
Distinguish declarative control from a sequence of imperative actions. With a declarative API, the operator states an intended result and controllers keep working toward it after the original command has finished. That is why a Deployment can replace a failed Pod without a human rerunning the deployment procedure, and why changing the declared replica count produces an ongoing new target rather than a one-time scaling script.
Scheduling connects workload requirements to cluster resources
KCNA expects foundational knowledge of scheduling and administration. Understand that Pods request resources and may express placement constraints, while the scheduler chooses an eligible node.
Learn the purpose of requests, limits, labels, selectors, taints, and tolerations conceptually. You do not need CKA-level command speed, but you should be able to explain why a Pod might remain Pending.
Relate scheduling to resilience. Replicas placed across appropriate nodes or failure zones reduce the chance that one infrastructure failure removes the entire service.
Networking and Services make ephemeral workloads reachable
Pods can be recreated with different addresses, so applications need stable service discovery and routing abstractions. Understand cluster networking, Services, DNS, and the role of network policy at a conceptual level.
The wider discussion of container orchestration helps show why networking is inseparable from scheduling: moving a workload is only useful if clients can still find and reach it.
Trace a request from one application to another using a Service name. Identify the DNS step, Service abstraction, and selected backend Pod. That flow is enough to anchor many KCNA networking questions.
Storage gives stateful applications a lifecycle beyond one Pod
Kubernetes separates workload lifecycle from persistent data lifecycle. The concepts in persistent volume claims are useful for understanding why applications request storage without needing to know the exact physical disk.
Know the purpose of persistent volumes, claims, storage classes, and dynamic provisioning. Focus on the abstraction: the application declares what storage it needs, while the platform maps that request to available storage.
This also illustrates the cloud-native separation of concerns. Application teams describe intent; platform capabilities fulfill it according to policy.
Application delivery should be declarative and repeatable
Cloud-native application delivery includes deployments, configuration, rollout, debugging, and the automation surrounding them. Understand why declarative manifests and version-controlled configuration are more reliable than manual server-by-server changes.
Tools such as Helm package reusable Kubernetes configuration; Helm charts provide helpful context for how teams parameterize and distribute complex application definitions.
Connect delivery to feedback. A rollout is not complete because a pipeline applied YAML; it is complete when the new version becomes healthy and observable.
Connect configuration and rollout strategy to change safety. ConfigMaps and Secrets separate environment-specific data from the container image, while rollout mechanisms let teams replace versions incrementally. The important KCNA-level idea is that delivery should be reproducible and observable: the same declared inputs should produce a predictable platform state, and health signals should show whether the new version is actually serving users.
GitOps extends that idea by treating version-controlled desired state as the reference and using automation to reconcile the cluster with it. Candidates do not need to master a specific GitOps product to understand the operating model: reviewed changes become traceable declarations, and drift becomes something the platform can detect and correct.
Observability is how operators know whether desired state is useful
A system can report that every Pod is Running while users still experience latency or errors. Cloud-native observability therefore includes metrics, logs, traces, events, and health signals that reflect both platform and application behavior.
Learn the difference between monitoring known conditions and exploring unknown failure behavior. Metrics may show rising latency, logs may explain an application error, and traces may reveal which service in a request path is slow.
KCNA does not require deep tooling expertise, but candidates should understand why observable systems are easier to operate and why telemetry is part of cloud-native architecture rather than an optional add-on.
Think of observability signals as complementary rather than competing. Metrics summarize behavior over time, logs preserve discrete application or platform events, traces connect work across service boundaries, and Kubernetes events explain many control-plane decisions. A useful troubleshooting question is which signal can reduce uncertainty fastest for the symptom being investigated.
Health checks also connect application behavior to orchestration. Readiness determines whether a workload should receive traffic, while liveness can help recover a stuck process. Misconfigured checks can therefore create outages of their own, which is a useful reminder that automation only improves reliability when its signals represent the application's real state.
The cloud-native ecosystem extends beyond Kubernetes itself
KCNA is intentionally broader than one product. The CNCF ecosystem includes projects for networking, observability, service mesh, delivery, storage, security, and other platform needs.
The overview of Kubernetes and cloud-native foundations is useful for connecting these categories without trying to memorize every project in the landscape.
Study project categories and problems first. If you know why a service mesh, observability system, policy engine, or GitOps controller exists, individual project names become easier to place.
Cloud-native architecture also depends on loose coupling between platform capabilities. Networking, storage, identity, policy, telemetry, and delivery systems expose interfaces that let teams change one layer without rebuilding the entire application stack. This modularity is one reason open standards and interoperable projects matter: organizations can assemble a platform around their operational needs while preserving the Kubernetes API as a common orchestration layer.
That does not mean every environment should adopt every CNCF category. A mature platform adds components to solve demonstrated problems. KCNA candidates should be able to describe the problem a project category addresses and the trade-off introduced by operating another distributed system.
Use small labs to turn broad theory into durable understanding
KCNA is multiple choice, but practical experimentation makes the concepts stick. Build a simple cluster, deploy an application, expose it, scale it, attach storage, and observe a failure. Then compare the experience with the Kubernetes learning curve and identify which layer caused the most confusion.
After KCNA, candidates can choose a direction: administration with CKA, application development with CKAD, or security foundations with KCSA.
The final readiness test is being able to explain the cloud-native value chain from container image to scheduled Pod, stable service, persistent data, automated delivery, and observable application behavior.
After each lab, explain the same system at three levels: what the application needs, which Kubernetes abstraction represents that need, and which platform component makes the abstraction real. If you can move among those levels without relying on command syntax, you are preparing for the conceptual style of KCNA rather than accidentally studying for an administrator exam.
Include one deliberate failure in every lab and explain which control loop, event, or telemetry signal reveals it. A concept becomes far easier to remember when it is connected to an observable platform behavior.
