Question 570

Acceptance testing must establish the following operational result: Client access validates routing resilience. Which verification action most directly establishes that outcome?

  1. Test reads and rejected writes at the secondary listener.
  2. Return HTTP 500 from one test backend and inspect traffic routing.
  3. Calculate loss exposure from real lag and write rate measurements.
  4. Rehearse failover and reconnect through the listener.

Explanation

Correct Answer

D:

Client access validates routing resilience.

Incorrect Answers

A:

That verification addresses the different requirement: Two regions must host SQL data but the second is allowed to be read-only before disaster. It does not directly establish client access validates routing resilience.

B:

This is a test for Two zonal web instances should receive traffic only while their HTTP health checks succeed. The requirement here is instead demonstrated by rehearse failover and reconnect through the listener.

C:

That verification addresses the different requirement: A zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. It does not directly establish client access validates routing resilience.

Question 571

Two regions must host SQL data but the second is allowed to be read-only before disaster. Which Azure architecture choice best meets this requirement?

  1. Claim listener automation guarantees cross-region synchronous durability.
  2. Write transactions directly to an ordinary secondary read-only replica.
  3. Use geo-replicated secondary reads with accepted asynchronous lag.
  4. Point clients to a literal primary region host forever.

Explanation

Correct Answer

C:

Read-only geo secondary can offload reports under a consistency trade-off.

Incorrect Answers

A:

Routing abstraction does not change replication consistency. In the present requirement, two regions must host SQL data but the second is allowed to be read-only before disaster. The needed design instead works because read-only geo secondary can offload reports under a consistency trade-off.

B:

The secondary is not automatically a multi-writer SQL master. This proposal contradicts the stated architecture constraint.

D:

Fixed endpoints create extra outage or manual reconfiguration after failover. In the present requirement, two regions must host SQL data but the second is allowed to be read-only before disaster. The needed design instead works because read-only geo secondary can offload reports under a consistency trade-off.

Question 572

An architecture proposal for regional sql failover groups relies on the following approach: Write transactions directly to an ordinary secondary read-only replica. Which specific failure or mismatch should the design reviewer identify?

  1. Fixed endpoints create extra outage or manual reconfiguration after failover.
  2. An open socket can coexist with a failed application dependency.
  3. Routing abstraction does not change replication consistency.
  4. The secondary is not automatically a multi-writer SQL master.

Explanation

Correct Answer

D:

Write transactions directly to an ordinary secondary read-only replica. The secondary is not automatically a multi-writer SQL master.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Point clients to a literal primary region host forever.' not to the recommendation under review. Here, The secondary is not automatically a multi-writer SQL master.

B:

This concern applies to Check only TCP socket acceptance and declare user transactions healthy. in another design for high availability design. The current proposal specifically fails because the secondary is not automatically a multi-writer SQL master.

C:

  2. Break a test login dependency and observe health-probe removal.
  3. Rehearse failover and reconnect through the listener.
  4. Calculate loss exposure from real lag and write rate measurements.

Explanation

Correct Answer

A:

Application behavior proves its designated role.

Incorrect Answers

B:

This is a test for An HTTP gateway sees a healthy VM heartbeat while the app's login endpoint is broken. The requirement here is instead demonstrated by test reads and rejected writes at the secondary listener.

C:

That verification addresses the different requirement: An application needs automatic regional SQL database failover under policy and a stable connection name. It does not directly establish application behavior proves its designated role.

D:

That verification addresses the different requirement: A zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. It does not directly establish application behavior proves its designated role.

Question 574

A zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. Which Azure architecture choice best meets this requirement?

  1. Claim listener automation guarantees cross-region synchronous durability.
  2. Point clients to a literal primary region host forever.
  3. Distinguish supported geo RPO limitations from zone-local synchronous HA.
  4. Write transactions directly to an ordinary secondary read-only replica.

Explanation

Correct Answer

C:

Geo-replication lag can cause lost committed writes during abrupt failure.

Incorrect Answers

A:

Routing abstraction does not change replication consistency. This proposal contradicts the stated architecture constraint.

B:

Fixed endpoints create extra outage or manual reconfiguration after failover. In the present requirement, a zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. The needed design instead works because geo-replication lag can cause lost committed writes during abrupt failure.

D:

The secondary is not automatically a multi-writer SQL master. In the present requirement, a zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. The needed design instead works because geo-replication lag can cause lost committed writes during abrupt failure.

Question 575

An architecture proposal for regional sql failover groups relies on the following approach: Claim listener automation guarantees cross-region synchronous durability. Which specific failure or mismatch should the design reviewer identify?

  1. Fixed endpoints create extra outage or manual reconfiguration after failover.
  2. Routing abstraction does not change replication consistency.
  3. The secondary is not automatically a multi-writer SQL master.
  4. Transport-layer routing does not provide HTTP path inspection or WAF.

Explanation

Correct Answer

B:

Claim listener automation guarantees cross-region synchronous durability. Routing abstraction does not change replication consistency.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Point clients to a literal primary region host forever.' not to the recommendation under review. Here, Routing abstraction does not change replication consistency.

C:

That assessment refers to the separate proposal 'Write transactions directly to an ordinary secondary read-only replica.' not to the recommendation under review. Here, Routing abstraction does not change replication consistency.

D:

This concern applies to Choose a basic Layer 4 load balancer for URL path rewrite and WAF. in another design for high availability design. The current proposal specifically fails because routing abstraction does not change replication consistency.

Question 576

Acceptance testing must establish the following operational result: Data-loss estimates inform an achievable SLA. Which verification action most directly establishes that outcome?

  1. Exercise path routing, certificate and WAF test rules.
  2. Calculate loss exposure from real lag and write rate measurements.
  3. Test reads and rejected writes at the secondary listener.
  4. Rehearse failover and reconnect through the listener.

Explanation

Correct Answer

B:

Data-loss estimates inform an achievable SLA.

Incorrect Answers

A:

This is a test for A service requires TLS termination, path-based routing and web application security. The requirement here is instead demonstrated by calculate loss exposure from real lag and write rate measurements.

C:

That verification addresses the different requirement: Two regions must host SQL data but the second is allowed to be read-only before disaster. It does not directly establish data-loss estimates inform an achievable SLA.

D:

That verification addresses the different requirement: An application needs automatic regional SQL database failover under policy and a stable connection name. It does not directly establish data-loss estimates inform an achievable SLA.

Question 577

A service must keep serving storage reads during one availability zone outage. Which Azure architecture choice best meets this requirement?

  1. Select compatible ZRS or GZRS storage for eligible services.
  2. Enable Archive on a ZRS account assuming all tiers are supported.
  3. Use only LRS and promise it has zonal distribution.
  4. Assume GRS without RA grants direct secondary reads automatically.

Explanation

Correct Answer

A:

Zone-replicated storage maintains local copies across availability zones.

Incorrect Answers

B:

Archive tier support differs by account and redundancy configuration. In the present requirement, a service must keep serving storage reads during one availability zone outage. The needed design instead works because zone-replicated storage maintains local copies across availability zones.

C:

LRS copies do not provide the same zonal failure boundary. This proposal contradicts the stated architecture constraint.

D:

Regular GRS protects copies without exposing the ordinary read endpoint. In the present requirement, a service must keep serving storage reads during one availability zone outage. The needed design instead works because zone-replicated storage maintains local copies across availability zones.

Question 578

  1. Regular GRS protects copies without exposing the ordinary read endpoint.
  2. LRS copies do not provide the same zonal failure boundary.
  3. Archive tier support differs by account and redundancy configuration.
  4. Simultaneous restarts cause avoidable full-service downtime.

Explanation

Correct Answer

B:

Use only LRS and promise it has zonal distribution. LRS copies do not provide the same zonal failure boundary.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Assume GRS without RA grants direct secondary reads automatically.' not to the recommendation under review. Here, LRS copies do not provide the same zonal failure boundary.

C:

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, LRS copies do not provide the same zonal failure boundary.

D:

This concern applies to Reboot all production instances at exactly the same instant. in another design for high availability design. The current proposal specifically fails because lRS copies do not provide the same zonal failure boundary.

Question 579

Acceptance testing must establish the following operational result: Storage reads during a test support the resiliency claim. Which verification action most directly establishes that outcome?

  2. Validate the storage account SKU and intended tier in a test deployment.
  3. Review account redundancy and simulate a zonal dependency failure.
  4. Perform a staged update and monitor healthy capacity throughout.

Explanation

Correct Answer

C:

Storage reads during a test support the resiliency claim.

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 storage reads during a test support the resiliency claim.

B:

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 storage reads during a test support the resiliency claim.
