Kubernetes and Cloud Native Associate KCNA Practice Test 39

Question 380

An operator notices this unresolved gap: A specific worker becomes NotReady while other nodes continue to run normally. What consequence BEST explains the need to address it?

  1. A correct Service name cannot compensate for a wrong backend port
  2. A readiness probe alone only changes traffic eligibility and will not restart it
  3. Restarting every Evicted Pod without fixing disk pressure perpetuates churn
  4. Retrying an application request does not restore a failing kubelet

Explanation

Correct Answer

D:

Retrying an application request does not restore a failing kubelet. This is the direct concern in the stated scenario because node Ready conditions summarize whether the node can safely host workloads. The matching mitigation is to inspect kubelet, runtime, node conditions, and network status. Successful verification would show that the node becomes Ready after the recorded condition clears.

Incorrect Answers

A:

Service targetPort maps the abstract port to the selected Pod's target. That explains the warning “A correct Service name cannot compensate for a wrong backend port”; this case instead concerns “Retrying an application request does not restore a failing kubelet”. Node Ready conditions summarize whether the node can safely host workloads.

B:

Liveness probes detect a running container that requires restart. That explains the warning “A readiness probe alone only changes traffic eligibility and will not restart it”; this case instead concerns “Retrying an application request does not restore a failing kubelet”. Node Ready conditions summarize whether the node can safely host workloads.

C:

Node resource pressure can trigger Pod eviction independent of application exit codes. That explains the warning “Restarting every Evicted Pod without fixing disk pressure perpetuates churn”; this case instead concerns “Retrying an application request does not restore a failing kubelet”. Node Ready conditions summarize whether the node can safely host workloads.

Question 381

In a Kubernetes environment this issue remains open: A team asks how to track changes to the Kubernetes API that affect its libraries. Which failure is the MOST direct consequence?

  1. Ignoring published deprecations can break dependent applications on cluster upgrades
  2. Assuming every hosted project has equal maturity can distort procurement decisions
  3. A private unreviewed patch may diverge from upstream behavior and maintenance practices
  4. Assuming every user can approve an upstream release obscures project governance

Explanation

Correct Answer

A:

Ignoring published deprecations can break dependent applications on cluster upgrades. This is the direct concern in the stated scenario because community release processes communicate API evolution and deprecation timelines. The matching mitigation is to follow Kubernetes release notes, enhancement proposals, and SIG documentation. Successful verification would show that compatibility tests pass against the scheduled release using documented migration guidance.

Incorrect Answers

B:

CNCF maturity stages such as Sandbox, Incubating, and Graduated have distinct meanings. That explains the warning “Assuming every hosted project has equal maturity can distort procurement decisions”; this case instead concerns “Ignoring published deprecations can break dependent applications on cluster upgrades”. Community release processes communicate API evolution and deprecation timelines.

C:

Kubernetes development is organized through open governance and special interest groups. That explains the warning “A private unreviewed patch may diverge from upstream behavior and maintenance practices”; this case instead concerns “Ignoring published deprecations can break dependent applications on cluster upgrades”. Community release processes communicate API evolution and deprecation timelines.

D:

Community roles and technical roles have different ownership and decision rights. That explains the warning “Assuming every user can approve an upstream release obscures project governance”; this case instead concerns “Ignoring published deprecations can break dependent applications on cluster upgrades”. Community release processes communicate API evolution and deprecation timelines.

Question 382

The platform team applies this control: Use multi-stage builds to separate build tools from runtime artifacts. The original issue is: A compiled application needs a tiny runtime image without source compilers. Which observation BEST validates the result?

  1. A basic experiment shows containers sharing the host kernel version
  2. The final image runs the binary without development toolchains installed
  3. Uploaded files remain accessible after a complete Pod replacement
  4. A replacement Pod starts with the intended dependency versions without manual setup

Explanation

Correct Answer

B:

The final image runs the binary without development toolchains installed. This is stronger than observing a saved configuration because it tests the actual outcome of use multi-stage builds to separate build tools from runtime artifacts. The underlying principle is that multi-stage builds copy only selected results into the final container image. The original risk was that shipping compilers and build caches unnecessarily increases image size and risk.

Incorrect Answers

A:

Containers package processes and dependencies without emulating a full guest OS. The observation “A basic experiment shows containers sharing the host kernel version” would validate that property, rather than the required “The final image runs the binary without development toolchains installed”. Multi-stage builds copy only selected results into the final container image.

C:

Container writable filesystems are ephemeral across replacement and rescheduling. The observation “Uploaded files remain accessible after a complete Pod replacement” would validate that property, rather than the required “The final image runs the binary without development toolchains installed”. Multi-stage builds copy only selected results into the final container image.

D:

Immutable image-based deployment moves application packaging into build workflows. The observation “A replacement Pod starts with the intended dependency versions without manual setup” would validate that property, rather than the required “The final image runs the binary without development toolchains installed”. Multi-stage builds copy only selected results into the final container image.

Question 383

In the situation "A new telemetry library sends spans but their relationships are lost between services", the team applies "Propagate supported trace context through each service call". Which outcome is the strongest verification?

  1. A shared collector receives usable traces and metrics from multiple service runtimes
  2. A controlled user-impact regression pages on-call while short harmless spikes do not
  3. A single trace contains parent-child spans across the whole request path
  4. A documented availability SLI drives a clear SLO and measured error budget

Explanation

Correct Answer

C:

A single trace contains parent-child spans across the whole request path. This is stronger than observing a saved configuration because it tests the actual outcome of propagate supported trace context through each service call. The underlying principle is that distributed tracing requires correlation propagation to connect spans across boundaries. The original risk was that independent unlinked spans cannot reconstruct end-to-end request latency.

Incorrect Answers

A:

OpenTelemetry standardizes telemetry generation and transport across languages. The observation “A shared collector receives usable traces and metrics from multiple service runtimes” would validate that property, rather than the required “A single trace contains parent-child spans across the whole request path”. Distributed tracing requires correlation propagation to connect spans across boundaries.

B:

Actionable alerting links signals to service health and response decisions. The observation “A controlled user-impact regression pages on-call while short harmless spikes do not” would validate that property, rather than the required “A single trace contains parent-child spans across the whole request path”. Distributed tracing requires correlation propagation to connect spans across boundaries.

D:

SLIs quantify observable service behavior while SLOs express a reliability target. The observation “A documented availability SLI drives a clear SLO and measured error budget” would validate that property, rather than the required “A single trace contains parent-child spans across the whole request path”. Distributed tracing requires correlation propagation to connect spans across boundaries.

Question 384

A team implemented the proposed remedy for this problem: A team asks how to track changes to the Kubernetes API that affect its libraries. Which evidence BEST shows it works?

  1. Multiple stakeholders participate through documented open community channels
  2. The change proposal is discussed in the correct SIG and receives documented review
  3. An onboarding guide maps each responsibility to the appropriate project process
  4. Compatibility tests pass against the scheduled release using documented migration guidance

Explanation

Correct Answer

D:

Compatibility tests pass against the scheduled release using documented migration guidance. This is stronger than observing a saved configuration because it tests the actual outcome of follow Kubernetes release notes, enhancement proposals, and SIG documentation. The underlying principle is that community release processes communicate API evolution and deprecation timelines. The original risk was that ignoring published deprecations can break dependent applications on cluster upgrades.

Incorrect Answers

A:

Vendor-neutral communities can coordinate shared cloud-native standards and adoption. The observation “Multiple stakeholders participate through documented open community channels” would validate that property, rather than the required “Compatibility tests pass against the scheduled release using documented migration guidance”. Community release processes communicate API evolution and deprecation timelines.

B:

Kubernetes development is organized through open governance and special interest groups. The observation “The change proposal is discussed in the correct SIG and receives documented review” would validate that property, rather than the required “Compatibility tests pass against the scheduled release using documented migration guidance”. Community release processes communicate API evolution and deprecation timelines.

C:

Community roles and technical roles have different ownership and decision rights. The observation “An onboarding guide maps each responsibility to the appropriate project process” would validate that property, rather than the required “Compatibility tests pass against the scheduled release using documented migration guidance”. Community release processes communicate API evolution and deprecation timelines.

Question 385

The team has not corrected this condition: A developer finds a bug in an upstream open-source dependency and wants to share a fix. Which risk is MOST relevant?

  1. Publishing an untested fix outside the community can fragment maintenance
  2. A private unreviewed patch may diverge from upstream behavior and maintenance practices
  3. Relying solely on one provider's private roadmap may increase dependency risk
  4. Ignoring published deprecations can break dependent applications on cluster upgrades

Explanation

Correct Answer

A:

Publishing an untested fix outside the community can fragment maintenance. This is the direct concern in the stated scenario because open-source collaboration relies on actionable reports and maintainer review. The matching mitigation is to submit a reproducible issue and reviewed pull request following project contribution rules. Successful verification would show that a maintainer reproduces the issue and merges an appropriately reviewed change.

Incorrect Answers

B:

Kubernetes development is organized through open governance and special interest groups. That explains the warning “A private unreviewed patch may diverge from upstream behavior and maintenance practices”; this case instead concerns “Publishing an untested fix outside the community can fragment maintenance”. Open-source collaboration relies on actionable reports and maintainer review.

C:

Vendor-neutral communities can coordinate shared cloud-native standards and adoption. That explains the warning “Relying solely on one provider's private roadmap may increase dependency risk”; this case instead concerns “Publishing an untested fix outside the community can fragment maintenance”. Open-source collaboration relies on actionable reports and maintainer review.

D:

Community release processes communicate API evolution and deprecation timelines. That explains the warning “Ignoring published deprecations can break dependent applications on cluster upgrades”; this case instead concerns “Publishing an untested fix outside the community can fragment maintenance”. Open-source collaboration relies on actionable reports and maintainer review.

Question 386

Given the requirement "A deployment needs to expand its disk while retaining the existing volume and data", the proposed fix is "Verify StorageClass expansion support and resize the PVC safely". Which principle explains why it works?

  1. PersistentVolumeClaims request storage independently of physical volume provisioning
  2. PVC expansion depends on driver support and filesystem resizing behavior
  3. Volume access modes express compatibility requirements for concurrent mounts
  4. Reclaim policies such as Delete and Retain control backing-volume disposition

Explanation

Correct Answer

B:

PVC expansion depends on driver support and filesystem resizing behavior. That principle directly explains the selected remediation, verify StorageClass expansion support and resize the PVC safely, for this case. Without the distinction, manually replacing storage with an undersized volume risks loss or outage. The expected confirmation is that capacity grows and prior data remains readable after resizing.

Incorrect Answers

A:

PersistentVolumeClaims request storage independently of physical volume provisioning. The operation “PersistentVolumeClaims request storage independently of physical volume provisioning” does not address the particular Kubernetes requirement “PVC expansion depends on driver support and filesystem resizing behavior”.

C:

Volume access modes express compatibility requirements for concurrent mounts. The operation “Volume access modes express compatibility requirements for concurrent mounts” does not address the particular Kubernetes requirement “PVC expansion depends on driver support and filesystem resizing behavior”.

D:

Reclaim policies such as Delete and Retain control backing-volume disposition. The operation “Reclaim policies such as Delete and Retain control backing-volume disposition” does not address the particular Kubernetes requirement “PVC expansion depends on driver support and filesystem resizing behavior”.

Question 387

A Kubernetes platform team observes this situation: A Pod cannot retrieve a private image from its authorized enterprise registry. Which action BEST addresses the requirement?

  1. Scan release artifacts and enforce an approved image policy before deployment
  2. Choose an appropriately minimal trusted runtime image and maintain updates
  3. Configure a scoped imagePullSecret on the appropriate Pod or service account
  4. Order build stages to reuse stable dependency layers when safe

Explanation

Correct Answer

C:

Configure a scoped imagePullSecret on the appropriate Pod or service account. This is appropriate for the described asset and control gap because registry authentication is distinct from Kubernetes workload API authorization. If the issue is left untreated, mounting registry credentials as unrelated app secrets will not fix image pulls. An assessor can verify remediation when image pulls succeed for the authorized registry while anonymous pulls fail.

Incorrect Answers

A:

Scan release artifacts and enforce an approved image policy before deployment. The operation “Scan release artifacts and enforce an approved image policy before deployment” does not address the particular Kubernetes requirement “Configure a scoped imagePullSecret on the appropriate Pod or service account”.

B:

Choose an appropriately minimal trusted runtime image and maintain updates. The operation “Choose an appropriately minimal trusted runtime image and maintain updates” does not address the particular Kubernetes requirement “Configure a scoped imagePullSecret on the appropriate Pod or service account”.

D:

Order build stages to reuse stable dependency layers when safe. The operation “Order build stages to reuse stable dependency layers when safe” does not address the particular Kubernetes requirement “Configure a scoped imagePullSecret on the appropriate Pod or service account”.

Question 388

The platform team applies this control: Remove unnecessary privileged mode, hostPath mounts, and Linux capabilities. The original issue is: A node-mounted privileged Pod needs to read its own configuration but asks for all host devices. Which observation BEST validates the result?

  1. The Pod accesses its own approved object and gets a denial for unrelated Secrets
  2. The container starts under an unprivileged UID and needed writes still succeed
  3. A privileged test Pod is rejected under the intended enforce setting
  4. A policy-compliant Pod operates without privileged mode or unnecessary host mounts

Explanation

Correct Answer

D:

A policy-compliant Pod operates without privileged mode or unnecessary host mounts. This is stronger than observing a saved configuration because it tests the actual outcome of remove unnecessary privileged mode, hostPath mounts, and Linux capabilities. The underlying principle is that pod security context and admission standards limit process and host access. The original risk was that unrestricted host mounts can let a compromised Pod affect worker filesystems.

Incorrect Answers

A:

Pod service-account identity controls API access for in-cluster workloads. The observation “The Pod accesses its own approved object and gets a denial for unrelated Secrets” would validate that property, rather than the required “A policy-compliant Pod operates without privileged mode or unnecessary host mounts”. Pod security context and admission standards limit process and host access.

B:

Security contexts can enforce nonroot process identity for Pod containers. The observation “The container starts under an unprivileged UID and needed writes still succeed” would validate that property, rather than the required “A policy-compliant Pod operates without privileged mode or unnecessary host mounts”. Pod security context and admission standards limit process and host access.

C:

Pod Security Admission uses namespace-level modes such as enforce, audit, and warn. The observation “A privileged test Pod is rejected under the intended enforce setting” would validate that property, rather than the required “A policy-compliant Pod operates without privileged mode or unnecessary host mounts”. Pod security context and admission standards limit process and host access.

Question 389

Given the requirement "A deployment must keep most existing Pods available while introducing a new image", the proposed fix is "Use a rolling update strategy with appropriate surge and unavailable limits". Which principle explains why it works?

  1. Rolling updates progressively replace Pods while controlling replacement availability
  2. Release tooling preserves revisions that support controlled restoration
  3. Kubernetes sends shutdown signals and allows bounded cleanup before forced stop
  4. Mixed-version rolling deployments require old and new software to tolerate shared data schema

Explanation

Correct Answer

A:

Rolling updates progressively replace Pods while controlling replacement availability. That principle directly explains the selected remediation, use a rolling update strategy with appropriate surge and unavailable limits, for this case. Without the distinction, deleting every old Pod at once may create a user-visible service outage. The expected confirmation is that healthy replicas remain available throughout the image rollout.

Incorrect Answers

B:

Release tooling preserves revisions that support controlled restoration. The operation “Release tooling preserves revisions that support controlled restoration” does not address the particular Kubernetes requirement “Rolling updates progressively replace Pods while controlling replacement availability”.

C:

Kubernetes sends shutdown signals and allows bounded cleanup before forced stop. The operation “Kubernetes sends shutdown signals and allows bounded cleanup before forced stop” does not address the particular Kubernetes requirement “Rolling updates progressively replace Pods while controlling replacement availability”.

D:

Mixed-version rolling deployments require old and new software to tolerate shared data schema. The operation “Mixed-version rolling deployments require old and new software to tolerate shared data schema” does not address the particular Kubernetes requirement “Rolling updates progressively replace Pods while controlling replacement availability”.

Question 390

In a Kubernetes environment this issue remains open: A compliance workload must never run on general-purpose worker nodes. Which failure is the MOST direct consequence?

  1. Deleting unrelated running Pods cannot create a matching node label
  2. Using a toleration alone can place the restricted Pod on ordinary nodes
  3. A preferred rule alone may allow placement on an unsuitable node
  4. Leaving workloads to drift can create hotspots after initial scheduling

Explanation

Correct Answer

B:

Using a toleration alone can place the restricted Pod on ordinary nodes. This is the direct concern in the stated scenario because tolerations remove a taint barrier but affinity enforces actual placement constraints. The matching mitigation is to combine required node affinity with the correct tolerations for the isolated pool. Successful verification would show that the Pod appears only on nodes labeled for the compliance pool.

Incorrect Answers

A:

Unsatisfied hard node affinity prevents scheduler placement despite free resources. That explains the warning “Deleting unrelated running Pods cannot create a matching node label”; this case instead concerns “Using a toleration alone can place the restricted Pod on ordinary nodes”. Tolerations remove a taint barrier but affinity enforces actual placement constraints.

C:

Hard placement constraints restrict eligible nodes through label matching. That explains the warning “A preferred rule alone may allow placement on an unsuitable node”; this case instead concerns “Using a toleration alone can place the restricted Pod on ordinary nodes”. Tolerations remove a taint barrier but affinity enforces actual placement constraints.

D:

Default placement is not continuous live-CPU load balancing among healthy nodes. That explains the warning “Leaving workloads to drift can create hotspots after initial scheduling”; this case instead concerns “Using a toleration alone can place the restricted Pod on ordinary nodes”. Tolerations remove a taint barrier but affinity enforces actual placement constraints.
