Microsoft AZ-104 Practice Test 10
Question 90
A CPU-based alert is noisy because normal traffic varies by hour and day. A newly created VM has only one day of metrics. Which TWO considerations support an adaptive Azure Monitor threshold without expecting immediate alerts? Choose TWO.
- Configure a supported metric alert with dynamic thresholds so it can learn normal patterns
- Force a one-minute query-based log alert and assume it always supports dynamic thresholds
- Disable all action groups permanently instead of tuning the alert
- Use one unchanged static CPU percentage as the only possible adaptive behavior
- Allow the dynamic-threshold rule sufficient samples and history to establish its baseline
Explanation
Correct Answers
A:Dynamic threshold metric alerts learn historic patterns and establish adaptive boundaries for unusual behavior rather than relying solely on one manually chosen static value. This is appropriate for a metric with recurring predictable peaks.
E:Dynamic threshold learning requires sufficient observations; Microsoft documents a minimum of three days and 30 samples before alerts can fire. A one-day-old VM may not have enough history, so plan baseline collection first.
Incorrect Answers
B:A fixed one-minute log-query frequency is not a universal supported setting for dynamic thresholds; feature and frequency limits apply. It also would not address the lack of historical learning data.
C:Permanently disabling notifications prevents responders from learning about real anomalous conditions. The requirement is to reduce noisy detection while retaining actionable alerts, not to remove observability.
D:A static percentage can be useful for stable signals but will not automatically learn daily or weekly seasonality. The stated request specifically calls for adaptive behavior across recurring workload patterns.
Question 91
An administrator needs guest operating-system performance and dependency views for several Azure VMs, not just subscription-level platform metrics. Which Azure Monitor capability should be considered?
- VM insights with its required collection configuration
- Azure Policy deny for public IPs
- A storage user delegation SAS
- An Azure DNS public zone
Explanation
Correct Answer
A:VM insights builds monitoring views for VM performance and supported dependencies using the required agent and data collection setup. Validate workspace, extension/agent health and expected telemetry coverage.
Incorrect Answers
B:A deny policy governs resource deployment compliance. It cannot collect guest operating-system performance counters or dependency observations.
C:SAS tokens delegate access to storage data, not guest monitoring. They do not install a monitoring agent.
D:Public DNS hosts naming records and cannot collect the VM's CPU, memory or process-related diagnostics.
Question 92
A hybrid network service intermittently fails from an Azure VM to an on-premises endpoint. Operations needs scheduled connectivity probes and historical reachability measurements. Which Azure tool fits?
- Azure Network Watcher Connection monitor
- Azure Blob lifecycle management
- A management-group delete lock
- Microsoft Entra SSPR
Explanation
Correct Answer
A:Connection monitor tests connectivity between supported sources and destinations over time and provides reachability and performance observations. Configure the intended endpoints, test settings and workspace so intermittent failures can be correlated with routing changes.
Incorrect Answers
B:Blob lifecycle management automates storage tiering or deletion; it does not probe a network service's reachability.
C:Management locks prevent certain resource changes but do not record whether hybrid TCP or ICMP paths are reachable.
D:SSPR resets user credentials and cannot measure network connectivity between cloud and on-premises endpoints.
Question 93
An administrator wants to determine who deleted a resource group yesterday, including the management operation and initiating identity. Which built-in Azure record should be examined first?
- The Azure Activity Log for the subscription
- Only the current CPU metric chart
- A blob snapshot listing
- Azure DNS zone records
Explanation
Correct Answer
A:The Activity Log records Azure management-plane events, including resource operations and their status and caller information where available. Filter the relevant subscription, resource group, timeframe and operation before interpreting the result.
Incorrect Answers
B:CPU metrics measure performance and are not an authoritative audit of who initiated a resource deletion.
C:Blob snapshots preserve data objects and do not record subscription management operations or the deleting principal.
D:DNS records map names to targets. Their present values cannot establish who deleted an Azure resource group yesterday.
Question 94
An Azure IaaS VM needs scheduled backup and retention of recovery points. Which TWO Azure Backup actions establish the protection? Choose TWO.
- Enable VM backup using a suitable Recovery Services vault
- An Azure public DNS zone with TTL 300
- An NSG rule named Backup
- A Blob Storage lifecycle policy alone
- Assign a backup policy that defines frequency and retention for the VM
Explanation
Correct Answers
A:The selected VM must be enrolled in supported backup protection and associated with the correct vault. Simply creating a vault does not protect any machine without enabling backup.
E:The backup policy supplies the expected recovery-point schedule and retention behavior. Verify initial backup success and restore support after applying the policy rather than relying on configuration alone.
Incorrect Answers
B:Public DNS hosts naming records rather than VM recovery points. TTL settings do not protect disks from accidental deletion or corruption.
C:NSGs restrict packet flows and cannot create application-consistent VM recovery points. A rule name offers no backup function.
D:Blob lifecycle policies act on stored objects and are not a substitute for the Azure VM backup and recovery orchestration of a vault.
Question 95
A backup policy is configured, but no Azure VM has been associated with it. Which additional action is needed before the administrator can expect scheduled recovery points?
- Enable backup for the target VM using the correct vault and policy
- Change the VM's resource tag to BackedUp
- Create a public IP on the VM
- Disable the vault's protected instance settings
Explanation
Correct Answer
A:A policy describes scheduling and retention but must be applied to the supported protected workload. Enable backup for the VM, verify successful initial backup and monitor subsequent job status.
Incorrect Answers
B:A BackedUp tag is only metadata. It neither enrolls the VM nor creates actual recovery points, and it could be misleading.
C:A public IP is unnecessary for Azure VM backup and expands network exposure without activating the policy.
D:Disabling vault protection does not start backup. It could remove safeguards that should remain enabled for a production recovery system.
Question 96
An Azure VM backup job completed successfully yesterday. A bad configuration update corrupted the guest OS this morning. What recovery capability should the administrator evaluate?
- Restore from a suitable Azure Backup recovery point, with a controlled recovery target
- Increase the VM's DNS TTL
- Assign all users subscription Owner
- Change the blob tier of an unrelated account
Explanation
Correct Answer
A:Azure Backup recovery points can be used to restore eligible VM disks or recreate a VM under supported restore scenarios. Select the desired recovery time, verify consistency and target configuration, and preserve evidence before destructive replacement.
Incorrect Answers
B:DNS TTL affects cached name resolution and does not restore OS or disk data from yesterday's backup.
C:Granting broad Owner access changes authorization, not machine state. It would add security risk without undoing corruption.
D:A blob tier change adjusts storage access economics and does not restore the VM's system configuration from an IaaS recovery point.
Question 97
A business continuity plan requires failover of eligible Azure VMs to another region after a regional outage. Which Azure service is designed for replication and orchestration?
- Azure Site Recovery
- Azure DNS zone delegation only
- Microsoft Entra group licensing
- Azure Cost Management budgets
Explanation
Correct Answer
A:Azure Site Recovery can replicate supported VM workloads and orchestrate failover to a secondary location with configured recovery points. Plan networking, capacity, test failover and the application's data dependencies before relying on it.
Incorrect Answers
B:DNS changes may redirect users after failover but do not replicate VM disks and configuration to another region.
C:License groups control user product entitlements and cannot run disaster recovery for Azure compute.
D:Budgets notify about spending; they cannot reproduce workloads in a paired region or execute failover plans.
Question 98
An operations team must rehearse Azure Site Recovery without interrupting the production VM. Which TWO test practices are appropriate? Choose TWO.
- Run Site Recovery test failover in a suitable isolated test VNet
- Unplanned production failover directly into the live VNet
- Delete the recovery policy and declare success
- Rotate the storage account key as a simulation
- Complete test-failover cleanup after validating the recovered workload
Explanation
Correct Answers
A:An isolated recovery network permits the team to start and assess a replica while production continues. Avoid connecting test instances directly to production services that could cause identity or data conflicts.
E:Cleanup closes the exercise and removes temporary test resources in the supported Site Recovery workflow. Record observed recovery behavior and outstanding issues before ending the drill.
Incorrect Answers
B:Unplanned production failover is intended for real recovery decisions and can disrupt traffic or data consistency. It is not the preferred non-disruptive rehearsal.
C:Removing protection destroys the disaster recovery configuration rather than verifying its usability. It cannot establish that the VM will recover correctly.
D:Rotating storage credentials tests an unrelated secret lifecycle and might break services. It does not validate replicated VM startup in a recovery region.
Question 99
A VM is deleted accidentally. The organization uses Azure Backup with soft delete enabled for protected backup data. What is the relevant protection?
- A retention window that can help recover deleted backup items according to vault protection rules
- Automatic restoration of every Azure VM without administrative action
- A guarantee that no account owner can delete any resource
- A substitute for testing backup and restore procedures
Explanation
Correct Answer
A:Soft delete protects eligible Azure Backup data after certain delete operations so it can be recovered within the configured protection period. Confirm vault settings and workload support; it does not replace managing real restore points.
Incorrect Answers
B:Soft delete does not mean every lost VM is automatically recreated with no recovery operation. Administrators must select and execute an appropriate restore workflow.
C:Soft delete protects backup data rather than universally preventing deletion of Azure resources. Management locks and RBAC are separate preventive controls.
D:Recoverability must still be tested. A configured protection setting cannot certify workload consistency, application behavior or RTO by itself.
Question 100
Operations wants a single view of Azure Backup jobs that have failed, together with protected-instance trends and actionable alerts. Which management approach best meets this?
- Configure Azure Backup monitoring, reporting and alerts for the relevant vaults
- Read only current VM CPU charts
- Enable anonymous access to storage accounts
- Change all management groups to a single tag
Explanation
Correct Answer
A:Azure Backup provides job status, reporting and alerting integrations that help identify failed backups and protection gaps. Confirm telemetry routing, permissions and alert recipients; review affected jobs rather than inferring success from policy existence.
Incorrect Answers
B:CPU charts can reveal compute stress but do not establish whether backup jobs succeeded or recovery points were retained.
C:Anonymous storage access weakens data security and does not surface backup job results. Recovery reporting is a monitoring configuration, not a public sharing requirement.
D:Management-group tags are unrelated to backup health and cannot consolidate vault job failures into a recovery operations view.
