Microsoft Azure Administrator AZ-104 Practice Test 89
Question 880
A public DNS A record exists in Azure but the Internet still sees records from another provider. What should be checked?
Azure Private DNS zone linked to that VNet
Authoritative DNS delegation at the domain registrar
Link the private DNS zone to the spoke or provide supported resolver forwarding
The appropriate privatelink private DNS zone with VNet linkage
Explanation
Correct Answer
B:
Resolvers follow delegated name servers, not arbitrary duplicate public zones. The relevant situation is that a public DNS A record exists in Azure but the Internet still sees records from another provider. DNS naming and TTL are distinct from load-balancer probes, frontends and backend traffic selection. “Azure Private DNS zone linked to that VNet” does not settle this requirement: Private DNS zones provide internal name resolution within linked networks. “Link the private DNS zone to the spoke or provide supported resolver forwarding” does not settle this requirement: Zone link or resolver design controls DNS visibility between networks. Verify the record type, cache behavior, frontend address and actual backend health as applicable.
Incorrect Answers
A:
Private DNS zones provide internal name resolution within linked networks. In this case, a public DNS A record exists in Azure but the Internet still sees records from another provider. “Azure Private DNS zone linked to that VNet” would not satisfy that requirement; the supported action is “Authoritative DNS delegation at the domain registrar”. Resolvers follow delegated name servers, not arbitrary duplicate public zones.
C:
Zone link or resolver design controls DNS visibility between networks. In this case, a public DNS A record exists in Azure but the Internet still sees records from another provider. “Link the private DNS zone to the spoke or provide supported resolver forwarding” would not satisfy that requirement; the supported action is “Authoritative DNS delegation at the domain registrar”. Resolvers follow delegated name servers, not arbitrary duplicate public zones.
D:
Private endpoint name resolution maps the service hostname to private addresses. In this case, a public DNS A record exists in Azure but the Internet still sees records from another provider. “The appropriate privatelink private DNS zone with VNet linkage” would not satisfy that requirement; the supported action is “Authoritative DNS delegation at the domain registrar”. Resolvers follow delegated name servers, not arbitrary duplicate public zones.
Question 881
A central Azure Private DNS zone already resolves an internal application name for one virtual network. A second authorized virtual network cannot resolve it, and no public DNS record is permitted. What link must be configured?
Publish the private hostname in public Azure DNS so every Internet resolver can query it
Enable an outbound NAT Gateway on the second VNet without any DNS link
Create a virtual network link from the existing Private DNS zone to the authorized second VNet
Change the DNS records into external CNAMEs without providing private name resolution
Explanation
Correct Answer
C:
Azure Private DNS zones require appropriate virtual network links for the VNets whose clients should resolve the contained private names through that service. Linking the existing zone to the second authorized VNet enables the intended resolution path without exposing the hostname publicly, subject to supported DNS settings. In this scenario, the correct choice is “Create a virtual network link from the existing Private DNS zone to the authorized second VNet”. Validate the DNS, health probe and frontend/backend behavior from a real supported client or request. “Publish the private hostname in public Azure DNS so every Internet resolver can query it” is not equivalent: A public DNS record violates the private-only requirement and may disclose internal hostnames. “Enable an outbound NAT Gateway on the second VNet without any DNS link” is not equivalent: NAT Gateway controls outbound source translation, not whether a VNet is linked to an Azure Private DNS zone.
Incorrect Answers
A:
A public DNS record violates the private-only requirement and may disclose internal hostnames. The competing choice “Publish the private hostname in public Azure DNS so every Internet resolver can query it” does not meet the specific requirement: A central Azure Private DNS zone already resolves an internal application name for one virtual network. A second authorized virtual network cannot resolve it, and no public DNS record is permitted. What link must be configured. The supported action is “Create a virtual network link from the existing Private DNS zone to the authorized second VNet”.
B:
NAT Gateway controls outbound source translation, not whether a VNet is linked to an Azure Private DNS zone. The competing choice “Enable an outbound NAT Gateway on the second VNet without any DNS link” does not meet the specific requirement: A central Azure Private DNS zone already resolves an internal application name for one virtual network. A second authorized virtual network cannot resolve it, and no public DNS record is permitted. What link must be configured. The supported action is “Create a virtual network link from the existing Private DNS zone to the authorized second VNet”.
D:
Changing to an externally resolved alias does not create the missing Private DNS zone link for the second VNet. The competing choice “Change the DNS records into external CNAMEs without providing private name resolution” does not meet the specific requirement: A central Azure Private DNS zone already resolves an internal application name for one virtual network. A second authorized virtual network cannot resolve it, and no public DNS record is permitted. What link must be configured. The supported action is “Create a virtual network link from the existing Private DNS zone to the authorized second VNet”.
Question 882
A new spoke VNet cannot resolve records from the private zone used by the hub. What should be configured?
The appropriate privatelink private DNS zone with VNet linkage
Depend on correct private DNS mapping for the official service hostname
Update the registrar delegation to the Azure DNS zone's authoritative name servers
Link the private DNS zone to the spoke or provide supported resolver forwarding
Explanation
Correct Answer
D:
Zone link or resolver design controls DNS visibility between networks. The relevant situation is that a new spoke VNet cannot resolve records from the private zone used by the hub. DNS naming and TTL are distinct from load-balancer probes, frontends and backend traffic selection. “The appropriate privatelink private DNS zone with VNet linkage” does not settle this requirement: Private endpoint name resolution maps the service hostname to private addresses. “Depend on correct private DNS mapping for the official service hostname” does not settle this requirement: Private Link endpoints can change during maintenance and are designed for DNS-based access.

Zone link or resolver design controls DNS visibility between networks.
C:
Creating an Azure public zone alone does not transfer Internet DNS authority. In this case, a new spoke VNet cannot resolve records from the private zone used by the hub. “Update the registrar delegation to the Azure DNS zone's authoritative name servers” would not satisfy that requirement; the supported action is “Link the private DNS zone to the spoke or provide supported resolver forwarding”. Zone link or resolver design controls DNS visibility between networks.

Question 887
An administrator is preparing a planned cutover of an IPv6-backed service to a new endpoint. Clients may have cached the existing AAAA record for hours. Which DNS preparation most directly reduces cache-related delay during the cutover?
Lower the applicable AAAA record TTL sufficiently before the cutover so caches can expire under the old policy
Create an A record containing the new IPv6 address
Reduce the authoritative AAAA TTL only at the cutover instant, after clients cached its earlier multi-hour value
Change the AAAA answer at cutover and assume all recursive caches immediately discard their stored old result
Explanation
Correct Answer
A:
A DNS time to live controls how long resolvers may cache an answer. Lowering the TTL in advance of a planned IPv6 endpoint change reduces the period during which clients continue using the old AAAA record after the switch. The reduction must be applied early enough for previously cached longer TTLs to expire. The relevant situation is that an administrator is preparing a planned cutover of an IPv6-backed service to a new endpoint. Clients may have cached the existing AAAA record for hours. DNS naming and TTL are distinct from load-balancer probes, frontends and backend traffic selection. “Create an A record containing the new IPv6 address” does not settle this requirement: A records are used for IPv4, not an IPv6 address. The record type cannot solve an existing AAAA cache timing concern. Verify the record type, cache behavior, frontend address and actual backend health as applicable.
Incorrect Answers
B:
A records are used for IPv4, not an IPv6 address. The record type cannot solve an existing AAAA cache timing concern. In this case, an administrator is preparing a planned cutover of an IPv6-backed service to a new endpoint. Clients may have cached the existing AAAA record for hours. “Create an A record containing the new IPv6 address” would not satisfy that requirement; the supported action is “Lower the applicable AAAA record TTL sufficiently before the cutover so caches can expire under the old policy”.
C:
Previously cached longer TTLs can persist after the authoritative record changes; DNS cache preparation must happen ahead of the cutover. In this case, an administrator is preparing a planned cutover of an IPv6-backed service to a new endpoint. Clients may have cached the existing AAAA record for hours. “Reduce the authoritative AAAA TTL only at the cutover instant, after clients cached its earlier multi-hour value” would not satisfy that requirement; the supported action is “Lower the applicable AAAA record TTL sufficiently before the cutover so caches can expire under the old policy”.

Microsoft AZ-104: Azure Administrator
Microsoft exam AZ-104, Microsoft Azure Administrator, is current as of October 1, 2026 and remains the core associate-level exam for administrators who implement, manage, and monitor Azure environments. Microsoft’s current blueprint, updated April 17, 2026, covers identities and governance, storage, compute, virtual networking, and monitoring. The associated Azure Administrator Associate credential is also an important prerequisite relationship for higher-level architecture work.
AZ-104 is broad because an Azure administrator rarely owns only one service. Real administration crosses Microsoft Entra ID, subscriptions, policy, storage, virtual machines, containers, App Service, networking, backup, monitoring, and automation. Candidates therefore need operational judgment: what to configure, where to apply it, how scope changes behavior, and how to troubleshoot when several Azure layers interact.
The exam also connects naturally to other roles. Networking specialists can deepen the virtual-networking material through AZ-700, while candidates moving toward architecture pair administrator experience with AZ-305. Across Microsoft certifications, AZ-104 is a practical administration foundation for roles that later specialize in networking, architecture, security, or other Azure disciplines.
Identity and governance determine who can change Azure and where those changes apply
Administrators should be comfortable with Microsoft Entra users and groups, external identities, licenses, self-service password reset, Azure roles, scopes, subscriptions, management groups, resource groups, tags, locks, budgets, and Azure Policy. These topics are related because access and governance become meaningful only when the candidate understands Azure’s hierarchy.
Azure role-based access control is especially important. A role definition describes permitted actions, while an assignment connects a security principal to that role at a scope. Exam scenarios often depend on inheritance, least privilege, and the difference between controlling Azure resources and managing identities themselves.
Storage questions are usually about access, resilience, lifecycle, and cost together
The blueprint includes storage accounts, redundancy, encryption, network restrictions, shared access signatures, stored access policies, access keys, identity-based access, Azure Files, Blob Storage, snapshots, soft delete, versioning, lifecycle rules, Azure Storage Explorer, and AzCopy. Rather than memorizing these as separate facts, candidates should understand the data-protection and access story they create.
Azure Blob Storage becomes easier to reason about when every scenario is reduced to who needs access, from where, for how long, with what recovery requirement, and at what expected access frequency. The correct combination of tiering, network controls, identity, redundancy, and retention follows from those constraints.
Compute administration now spans VMs, scale, containers, and App Service
AZ-104 still expects strong virtual-machine administration, including sizing, disks, availability options, movement, encryption, and scale sets. It also covers Azure Container Registry, Container Instances, Container Apps, and App Service configuration. This mix reflects the reality that administrators support both traditional server workloads and managed application platforms.
Infrastructure automation is part of that responsibility. Candidates should be able to interpret and modify ARM templates or Bicep files and use them to deploy repeatable resources. The goal is not to become a full-time infrastructure-as-code developer, but to understand declarative deployment well enough to avoid treating the portal as the only administrative interface.
Virtual networking requires understanding traffic flow rather than memorizing settings
Virtual networks, subnets, peering, public IP addresses, routes, network security groups, application security groups, Bastion, service endpoints, private endpoints, DNS, and connectivity troubleshooting form one system. A strong candidate can trace a packet mentally: name resolution, route selection, filtering, endpoint type, and destination reachability.
Azure DNS is one part of that path, while deeper network design belongs to AZ-700. For AZ-104, administrators should be able to identify whether a failure is caused by DNS, routing, NSG rules, peering, endpoint configuration, or the workload itself before changing settings at random.
Monitoring becomes useful only when signals lead to an operational response
Azure Monitor, metrics, logs, alerts, action groups, Log Analytics, Network Watcher, and Advisor help administrators detect and diagnose problems. The Azure logging and monitoring concepts are easier to retain when tied to a question: what signal would show that the service is failing, who should receive it, and what context is needed to act?
Exam scenarios may distinguish platform metrics from queryable log data or ask which tool supports a particular troubleshooting need. Hands-on practice should include creating an alert, querying logs, reviewing resource health, and using diagnostic tools during a deliberately introduced failure. Operational familiarity makes the wording of monitoring questions much less abstract.
Backup and recovery should be planned as service objectives
Administrators need to know how Azure Backup and Site Recovery fit business continuity without assuming they solve the same problem. Backup protects recoverable data and restore points, while replication and failover address workload continuity across locations. Recovery requirements should be expressed through acceptable data loss, acceptable downtime, retention, and testing.
These decisions connect to architecture because availability zones, redundancy, backup, replication, and application-level design can overlap. An AZ-104 candidate should be able to identify the administrative control needed for the stated requirement while recognizing when a broader architecture decision belongs to a solutions architect.
Cost and governance are operational concerns, not finance-only topics
Budgets, cost alerts, Advisor recommendations, tags, policy, and resource organization affect whether an Azure environment remains manageable as it grows. The subscription and management hierarchy provides the structure for applying controls consistently across teams and environments.
A useful lab is to design a small organization with management groups, subscriptions, resource groups, RBAC assignments, tags, a policy, and a budget. Then explain why each control is placed at its chosen scope. That exercise combines several AZ-104 domains and reinforces the idea that governance is about repeatable operational boundaries rather than isolated settings.
Effective AZ-104 preparation alternates configuration with troubleshooting
Reading a study guide is not enough because many objectives are procedural. Build a small environment, configure identities and storage, deploy a VM and an App Service, establish networking, enable monitoring, and deliberately break selected configurations. Troubleshooting the resulting symptoms forces candidates to understand dependencies rather than simply remember where options appear in the portal.
AZ-104 remains valuable because it teaches the operating layer that other Azure roles depend on. Architects need administrators who can implement designs, network engineers rely on correctly managed resource infrastructure, security engineers depend on sound identity and governance, and DevOps teams need stable subscriptions and services. Treat the exam as an operational systems test and the breadth becomes coherent.
Microsoft Entra and Azure authorization deserve separate mental models. Entra roles govern identity-directory functions, while Azure RBAC controls management of Azure resources. Confusing the two can lead to exam mistakes and real privilege problems. A user might be able to manage a resource group without being able to administer directory users, or manage identities without having rights to modify a virtual network. Always identify the control plane before choosing a role.
Resource locks and policy also solve different governance problems. A lock can prevent deletion or modification at a scope, while Azure Policy evaluates or enforces whether resources comply with organizational rules. Tags help with classification and cost management but are not security boundaries. Designing a lab that uses all three makes their purposes clearer than memorizing definitions because the learner can observe what each mechanism blocks, audits, or labels.
Storage security becomes easier when candidates separate authentication from authorization and network reachability. A request can fail because the caller has no credential, because the credential lacks data-plane permissions, because the storage firewall blocks the source, or because the requested object no longer exists. Shared access signatures add another dimension because scope and expiry are encoded into delegated access. Troubleshooting should determine which layer rejected the request before regenerating keys or opening networks.
For compute, administrators should practice both lifecycle operations and configuration drift. Creating a VM is only the beginning; real work includes resizing, disk changes, extension management, availability placement, backup, monitoring, and safe movement across resource groups or subscriptions. Container and App Service workloads have different lifecycle controls, so the exam rewards candidates who know when infrastructure management ends and platform management begins.
Networking labs should include effective-security-rule and effective-route inspection. These tools reveal the combined result of configuration applied at several scopes, which is often more useful than reading one NSG or route table in isolation. Add Bastion or a private endpoint and the environment becomes a realistic troubleshooting exercise where identity, DNS, network security, and service configuration all have to align.
Administrators should also build a habit of using Azure CLI or PowerShell for repeatable inspection. The exam may not ask for long scripts, but operational work benefits from commands that list resources, query configuration, or apply consistent changes across many objects. Pair those tools with Bicep for declarative deployment and the candidate gains a more realistic administrative toolkit than a portal-only study plan can provide.
Recovery drills are valuable because backup configuration can look healthy until someone needs a restore. Create a small protected workload, generate restore points, recover data or a VM, and verify access after restoration. This reveals dependencies such as network configuration, identity, DNS, and application state that may not be obvious from the backup job alone. Administrators should learn to distinguish successful backup completion from successful business recovery.
Resource movement and lifecycle questions also reward awareness of dependencies. Moving resources between groups, subscriptions, or regions may affect IDs, permissions, locks, networking, or service-specific limitations. Before changing location or ownership boundaries, inspect dependent resources and role assignments. This is a useful administrative habit because Azure environments evolve continuously; clean day-one design does not prevent later reorganizations.
