Question 880

A VM backup job finishes successfully, but the organization also needs to know whether it can restore a selected application file. Which evidence supplements the scheduled backup job's success state?

  1. Perform a documented restore validation of representative data into a safe location
  2. Count scheduled backup jobs alone as conclusive proof that every file is recoverable
  3. Enable Recovery Services vault soft delete and treat it as proof that a selected application file can be recovered
  4. Increase the VM backup schedule from daily to hourly without ever testing a file-level restore

Explanation

Correct Answer

A:

A successful backup operation proves the job ran, not that a particular file can be restored correctly under real recovery conditions. Restore tests validate recoverability end to end.

Incorrect Answers

B:

Job completion and usability of a selected restore are distinct. Corruption, missed application components or procedural gaps can remain undetected.

C:

Soft delete helps protect backup data from accidental or malicious removal. It does not demonstrate that a specific file exists, is usable, or can be restored; perform a representative restore test.

D:

More frequent successful jobs increase recovery points but do not prove the selected application file is present and recoverable. A safe trial restore is direct evidence.

Question 881

An operations team wants different backup retention for production and development VMs without maintaining custom policies for each VM separately. What reuse model should it adopt?

  1. Create Azure Backup alerts for production and development VMs but keep the same retention policy on every VM
  2. Define reusable backup policies for the differing retention requirements and assign eligible VMs appropriately
  3. Use one policy for all VMs and give each resource a tag called retentionDays
  4. Put all VMs in one availability set because it shares backup retention

Explanation

Correct Answer

B:

Vault backup policies centralize schedule and retention behavior. Separate production and development policies let many VMs share the correct settings without manual per-VM drift.

Incorrect Answers

A:

Alerts can report backup events or missed jobs but cannot supply different recovery-point expiration requirements. Reusable backup policies with production and development retention configurations are needed; alerts are only monitoring around those policies.

C:

A tag by itself does not change the backup schedule/retention applied by a policy. The protection assignment must use the appropriate policy settings.

D:

Availability sets manage hardware fault and update domain placement rather than vault retention behavior.

Question 882

A protected Azure VM uses a Standard backup policy, and operations plans to move it to a supported configuration with multiple daily recovery points and longer operational snapshot retention. They want to retain the existing protected item's backup history rather than stop protection and start from scratch. Which supported change should be evaluated?

  1. Stop protection with Delete backup data, then recreate protection under an Enhanced policy and assume historical recovery points persist
  2. Modify only the Standard policy's daily retention to make it run every four hours
  3. Use the supported Standard-to-Enhanced VM backup policy migration workflow and verify workload prerequisites
  4. Add four daily schedules to the unchanged Standard policy and assume it becomes an Enhanced policy automatically

Explanation

Correct Answer

C:

Microsoft documents an in-place Standard-to-Enhanced policy migration path for supported Azure VM backups. Evaluate the VM's disk types and feature prerequisites, the protection object's compatibility, enhanced schedule and operational-tier retention before making the change. Preserve and verify existing recovery-point continuity during migration.

Incorrect Answers

A:

Deleting backup data conflicts with the stated requirement to retain existing recovery points. A supported Standard-to-Enhanced migration keeps the protected item and history where prerequisites allow.

B:

Daily retention determines how long points remain available; it does not convert Standard's once-daily scheduling into Enhanced's supported subdaily schedule. Changing retention alone therefore cannot meet the faster recovery point objective or extended snapshot-tier capability.

D:

A Standard policy does not acquire Enhanced policy capabilities merely by editing its display/schedule settings. Use the supported migration flow and verify the workload requirements.

Question 883

A production VM experiences an operating-system failure after a bad patch. Its Recovery Services vault contains a recent valid recovery point, and the operations team needs an isolated restored machine for testing before changing production. Which Azure Backup operation should be used?

  1. Restore a new VM from the chosen recovery point
  2. Restore VM disks in place on the failed production VM before validating the recovery point
  3. Restore individual application files only, leaving the failed operating system untouched
  4. Run an Azure Site Recovery failover even though no Site Recovery replication is configured

Explanation

Correct Answer

A:

Restoring a new VM from a selected recovery point provides an independent instance that can be checked before cutover, while retaining the original failed VM for investigation.

Incorrect Answers

B:

In-place restoration can overwrite or affect the failed production workload and does not provide the requested isolated testing environment. A new VM is safer for validation.

C:

File-level restoration can recover selected files but does not replace the damaged OS and boot configuration the team needs to validate.

D:

Azure Backup recovery points and Site Recovery replication are different services. A failover cannot use only the backup vault recovery point as its replication source.

Question 884

An employee accidentally deleted one directory from an Azure VM yesterday, but the rest of the production VM is healthy. A valid VM backup recovery point includes the directory. The team wants the least disruptive restoration approach. What should it investigate?

  1. Replace the entire production VM automatically before checking available recovery options
  2. Take a new managed disk snapshot of the production VM today and recover the directory that was deleted yesterday from that new snapshot
  3. Restore the entire production VM from the recovery point because Azure VM Backup cannot expose a single file or directory for recovery
  4. Azure VM Backup file recovery from the selected recovery point to restore the required files

Explanation

Correct Answer

D:

File recovery lets authorized operators retrieve specific content from a VM backup without unnecessarily replacing the entire running VM. It matches a narrow accidental deletion.

Incorrect Answers

A:

A full VM restore is more disruptive than retrieving a single directory and can overwrite healthy current state. Narrow file recovery should be considered first.

B:

A snapshot taken after the directory has already been deleted captures the current disk state, not the earlier deleted files. The valid historical Azure VM Backup recovery point is the relevant recovery source.

C:

Azure VM Backup supports file recovery from appropriate recovery points, so restoring the entire VM is not necessary just to recover one directory. A full VM restore could overwrite healthy current state and is more disruptive than extracting the missing files.

Question 885

A security incident team needs a recoverable copy of an Azure VM’s disks from before a suspected compromise. Investigators will inspect the copy without replacing or rebooting the live workload. Which Azure Backup restore approach suits that?

  1. Restore disks from the selected VM backup recovery point into separate managed disk resources
  2. Automatically overwrite the current VM as soon as the recovery point is selected
  3. Create a fresh snapshot of the live VM disks now and label it the historical pre-compromise recovery point
  4. Perform an Azure Site Recovery failover and assume its latest replicated data is always the required pre-compromise disk copy

Explanation

Correct Answer

A:

Restoring disks allows investigators to attach or inspect recovered data separately while leaving the running production VM unchanged. It is preferable to an immediate in-place overwrite for forensics.

Incorrect Answers

B:

Replacing production destroys the separation needed for investigation and risks losing current evidence. The scenario explicitly forbids rebooting or replacing it.

C:

A snapshot created after the suspected compromise captures the current potentially tainted data, not the known earlier recovery point required for forensics. Restore separate managed disks from an eligible pre-incident Azure Backup point instead of re-labeling a new snapshot.

D:

Site Recovery replicates workload state for disaster recovery and its latest replica is not automatically a clean pre-incident forensic backup. The requirement identifies a known earlier Azure Backup recovery point, which can be restored as separate disks without replacing the live VM.

Question 886

An Azure VM protected by a Recovery Services vault had a customized topology with multiple NICs, a reserved private IP and an internal Load Balancer association. After a destructive failure, the team must reconstruct the special network layout from a valid backup recovery point rather than rely on a basic quick-create restore. Which restore approach provides the required customization?

  1. Restore only a single application file from inside the recovery point and assume it recreates the VM network interfaces
  2. Choose the Restore disks path, then use the resulting template/disks to build a VM with the required customized network configuration
  3. Use Create new VM restore without further customization, assuming its default workflow reconstructs every original additional NIC and internal Load Balancer membership
  4. Restore the VM disks and attach them to a different existing VM without defining the replacement VM network interfaces or load-balancer backend membership

Explanation

Correct Answer

B:

Microsoft documents Restore disks for backed-up Azure VMs that require specialized network layout, including multiple NICs, reserved IP addresses and internal or external load balancing. The recovery workflow exposes disk material and a deployable template so administrators can customize networking while creating the new VM. This differs from a basic quick-create VM restore that does not express all intended specialized settings.

Incorrect Answers

A:

File recovery is useful when an individual document or file must be recovered, but it does not reconstruct a complete VM with multiple NICs and an internal load balancer arrangement. The failure requires rebuilding compute and its specialized network connections. An isolated file restore would leave the core workload infrastructure absent.

C:

Basic Create new VM recovery can produce a VM from a backup, but should not be relied on to reconstruct all stated special network layout elements automatically. This workload needs multiple NICs, a reserved private address and specific internal Load Balancer association; Microsoft points to Restore disks and template-based customization for those configurations.

D:

Restored disks contain storage state, not instructions for the required multiple network interfaces or internal Load Balancer attachments. Attaching the disks to an unrelated VM also fails the scenario’s objective of reconstructing a correctly configured replacement workload. Restore disks can be the first step, but template and networking customization are still necessary.

Question 887

An Azure VM was restored to a new VM in another resource group from a recovery point. Operations assumes the new machine immediately inherits the original VM's daily Azure Backup protection schedule. What should they verify?

  1. Explicitly configure or verify Azure Backup protection and policy for the restored new VM
  2. Assume original VM protection automatically applies to every VM created from its disk history
  3. Restore the VM with its original IP address and assume this also enrolls new backup protection
  4. Restore the new VM into the same resource group as the old VM and assume their matching resource-group scope transfers the original protection policy

Explanation

Correct Answer

A:

A restored alternate VM can be a distinct protected resource. Its ongoing scheduled backup policy should be set up and checked independently instead of assuming the source association automatically transfers.

Incorrect Answers

B:

Protection is tracked for individual backup items and does not automatically enroll all future clones of a machine.

C:

Network addressing does not establish a protection relationship between the restored new VM and the Recovery Services vault policy.

D:

Resource-group placement does not automatically enroll a newly created VM in the original protected item’s Backup policy. The restored VM has its own resource identity and must have backup protection explicitly configured or verified in the appropriate vault.

Question 888

A storage account has Azure Blob operational backup. An operator deleted an entire container rather than individual blobs. They now attempt an operational point-in-time restore and receive a failure for that container. Which missing protection would have specifically addressed container deletion?

  1. Use a longer Azure resource-group deletion lock after the container has already been deleted
  2. Container soft delete, configured before deletion, to recover the container within retention
  3. Increase the operational Blob backup schedule frequency to hourly
  4. Enable only blob soft delete and expect the deleted container itself to be recoverable

Explanation

Correct Answer

B:

Operational point-in-time restore cannot restore a deleted container through its ordinary blob range restore. Container soft delete is a separate feature that can recover a deleted container during its configured window.

Incorrect Answers

A:

A control-plane lock applied after deletion cannot reconstruct a deleted container, and management locks are not reliable blob data-plane recovery mechanisms.

C:

Operational Blob backup uses continuous change tracking, not a periodic schedule whose frequency could restore a deleted container.

D:

Blob soft delete retains deleted blob objects, not the deleted container as an object. Container soft delete is a separate feature.

Question 889

A VM has one OS disk plus three managed data disks. One 2-TB data disk contains reproducible cache data and does not need Azure VM Backup protection; the other two data disks must remain protected. The team proposes excluding only the OS disk to save more capacity. Which selective-disk backup plan is supported?

  1. Exclude the OS disk and protect only the data disks; the VM image can boot using any protected data disk.
  2. Keep the OS disk in the backup and use selective disk backup to exclude the noncritical cache data disk while including the required data disks.
  3. Exclude every disk and rely on the Recovery Services vault metadata to reconstruct all VM files later.
  4. Replace VM backup with a VMSS automatic-repair policy, which creates recoverable point-in-time backups of selected disks.

Explanation

Correct Answer

B:

Azure Backup selective disk backup supports choosing included or excluded managed data disks while always including the OS disk. Exclude the cache data disk by supported selection methods, but protect both data disks containing required state. Verify any volumes spanning multiple disks are protected together or restore could be incomplete.

Incorrect Answers

A:

Azure VM selective disk backup always includes the VM OS disk; it is not an optional disk that can be excluded while retaining only data disks. A recovered data disk alone also does not provide the protected OS image for normal VM recovery.

C:

A Recovery Services vault stores backups of included disks, not missing payload data for disks explicitly excluded from a recovery point. Excluding every disk would neither provide a supported VM backup nor allow the vault to regenerate discarded cache or production data.

D:

VMSS repair operations restart, reimage or replace unhealthy instances; they are not recovery points for chosen disks. An automatic-repair policy cannot replace a selective Azure Backup disk-protection and retention design.

Question 890

An Azure VM backup in a Recovery Services vault has an eligible vault-tier recovery point. The vault allows Cross Subscription Restore, the target subscription is in the same tenant and the restore operator has the required roles. The restore wizard nevertheless returns UserErrorCrossSubscriptionRestoreInvalidTargetSubscription. What target-side prerequisite should be checked?

  1. Register the Microsoft.RecoveryServices resource provider in the destination Azure subscription before retrying the supported restore
  2. Replace the target subscription by a new Azure availability set; provider registration is controlled by VM placement
  3. Remove the Azure Backup recovery point from vault storage and create a snapshot-only local backup
  4. Disable Cross Subscription Restore on the vault so that the wizard can select the target subscription automatically

Explanation

Correct Answer

A:

Microsoft documents that UserErrorCrossSubscriptionRestoreInvalidTargetSubscription indicates the destination subscription is not registered with the Azure Recovery Services resource provider. Register the provider in the target subscription, confirm permissions and vault settings, and retry the cross-subscription restore. The chosen recovery point and tenant are already eligible in this scenario.

Incorrect Answers

B:

Availability sets spread VMs across update and fault domains for availability. They are not a control-plane substitute for subscription-level resource provider registration. Changing VM placement will not make Azure Recovery Services accept a destination subscription that is missing the provider.

C:

A snapshot-only recovery point cannot replace the eligible vault-tier recovery point for a cross-subscription destination. Deleting backup history risks data protection and does nothing to register required service providers in the destination subscription.

D:

Disabling the vault’s Cross Subscription Restore capability explicitly prevents the requested operation to another subscription. The problem is not an overly permissive setting but a missing subscription-level registration; disabling CSR would add a second blocker rather than resolve the provider error.
