Microsoft AZ-305 Practice Test 59
Question 580
A service must read data from a standby region before failover of storage write authority. Which Azure architecture choice best meets this requirement?
- Use only LRS and promise it has zonal distribution.
- Enable Archive on a ZRS account assuming all tiers are supported.
- Assume GRS without RA grants direct secondary reads automatically.
- Use RA-GRS or RA-GZRS where supported and design secondary read handling.
Explanation
Correct Answer
D:Read-access geo redundancy exposes data to a read-only regional endpoint.
Incorrect Answers
A:LRS copies do not provide the same zonal failure boundary. In the present requirement, a service must read data from a standby region before failover of storage write authority. The needed design instead works because read-access geo redundancy exposes data to a read-only regional endpoint.
B:Archive tier support differs by account and redundancy configuration. In the present requirement, a service must read data from a standby region before failover of storage write authority. The needed design instead works because read-access geo redundancy exposes data to a read-only regional endpoint.
C:Regular GRS protects copies without exposing the ordinary read endpoint. This proposal contradicts the stated architecture constraint.
Question 581
An architecture proposal for storage zone and geo availability relies on the following approach: Assume GRS without RA grants direct secondary reads automatically. Which specific failure or mismatch should the design reviewer identify?
- Autoscale can delete the only record of the session.
- LRS copies do not provide the same zonal failure boundary.
- Regular GRS protects copies without exposing the ordinary read endpoint.
- Archive tier support differs by account and redundancy configuration.
Explanation
Correct Answer
C:Assume GRS without RA grants direct secondary reads automatically. Regular GRS protects copies without exposing the ordinary read endpoint.
Incorrect Answers
A:This concern applies to Store the only copy of user sessions on each scale-in eligible VM. in another design for high availability design. The current proposal specifically fails because regular GRS protects copies without exposing the ordinary read endpoint.
B:That assessment refers to the separate proposal 'Use only LRS and promise it has zonal distribution.' not to the recommendation under review. Here, Regular GRS protects copies without exposing the ordinary read endpoint.
D:That assessment refers to the separate proposal 'Enable Archive on a ZRS account assuming all tiers are supported.' not to the recommendation under review. Here, Regular GRS protects copies without exposing the ordinary read endpoint.
Question 582
Acceptance testing must establish the following operational result: Tests establish actual readable data with a staleness bound. Which verification action most directly establishes that outcome?
- Query the secondary endpoint and inspect object replication timing.
- Review account redundancy and simulate a zonal dependency failure.
- Validate the storage account SKU and intended tier in a test deployment.
- Delete a worker during an active session and check continuity.
Explanation
Correct Answer
A:Tests establish actual readable data with a staleness bound.
Incorrect Answers
B:That verification addresses the different requirement: A service must keep serving storage reads during one availability zone outage. It does not directly establish tests establish actual readable data with a staleness bound.
C:That verification addresses the different requirement: An archive compliance store uses an access tier that is incompatible with a proposed redundancy choice. It does not directly establish tests establish actual readable data with a staleness bound.
D:This is a test for A VMSS contains stateful sessions tied to local instance disks that cannot survive replacement. The requirement here is instead demonstrated by query the secondary endpoint and inspect object replication timing.
Question 583

A:That assessment refers to the separate proposal 'Assume GRS without RA grants direct secondary reads automatically.' not to the recommendation under review. Here, Archive tier support differs by account and redundancy configuration.
C:That assessment refers to the separate proposal 'Use only LRS and promise it has zonal distribution.' not to the recommendation under review. Here, Archive tier support differs by account and redundancy configuration.
D:This concern applies to Manually provision each VM and detect failure only through user complaints. in another design for high availability design. The current proposal specifically fails because archive tier support differs by account and redundancy configuration.
Question 585
Acceptance testing must establish the following operational result: Deployment results prevent incompatible storage design. Which verification action most directly establishes that outcome?
- Query the secondary endpoint and inspect object replication timing.
- Validate the storage account SKU and intended tier in a test deployment.
- Generate load and terminate a test instance while observing replacement.
- Review account redundancy and simulate a zonal dependency failure.
Explanation
Correct Answer
B:Deployment results prevent incompatible storage design.
Incorrect Answers
A:That verification addresses the different requirement: A service must read data from a standby region before failover of storage write authority. It does not directly establish deployment results prevent incompatible storage design.
C:This is a test for A regional stateless web fleet must replace failed instances and scale on aggregate CPU. The requirement here is instead demonstrated by validate the storage account SKU and intended tier in a test deployment.
D:That verification addresses the different requirement: A service must keep serving storage reads during one availability zone outage. It does not directly establish deployment results prevent incompatible storage design.
Question 586
Two zonal web instances should receive traffic only while their HTTP health checks succeed. Which Azure architecture choice best meets this requirement?
- Check only TCP socket acceptance and declare user transactions healthy.
- Use an appropriate Azure load balancer or HTTP gateway with health probing.
- Use static DNS records with no endpoint health evaluation as the only failover.
- Choose a basic Layer 4 load balancer for URL path rewrite and WAF.
Explanation
Correct Answer
B:Health probes remove failed backends from normal routing.
Incorrect Answers
A:An open socket can coexist with a failed application dependency. In the present requirement, two zonal web instances should receive traffic only while their HTTP health checks succeed. The needed design instead works because health probes remove failed backends from normal routing.
C:Static records cannot react immediately to application failure. This proposal contradicts the stated architecture constraint.
