Question 600

Acceptance testing must establish the following operational result: Layered exercises identify which component supplies each recovery guarantee. Which verification action most directly establishes that outcome?

  1. Test a regional frontend outage independently from database failover.
  2. Disable one test origin and inspect global route selection.
  3. Run a primary-region dependency outage drill while tracing transactions.
  4. Perform a staged update and monitor healthy capacity throughout.

Explanation

Correct Answer

A:

Layered exercises identify which component supplies each recovery guarantee.

Incorrect Answers

B:

That verification addresses the different requirement: A public web application needs one global hostname with rapid regional failover based on health. It does not directly establish layered exercises identify which component supplies each recovery guarantee.

C:

That verification addresses the different requirement: An active-active regional design uses a shared external service that exists only in the primary region. It does not directly establish layered exercises identify which component supplies each recovery guarantee.

D:

This is a test for A company wants uniform VM OS updates across a large instance fleet without taking the whole site down. The requirement here is instead demonstrated by test a regional frontend outage independently from database failover.

Question 601

An active-active regional design uses a shared external service that exists only in the primary region. Which Azure architecture choice best meets this requirement?

  1. Claim Front Door alone replicates SQL transactions to all regions.
  2. Map and eliminate critical single-region dependencies before claiming multi-region HA.
  3. Count two web regions and ignore their common single-region secret store.
  4. Depend only on one regional VM load balancer to survive an entire Azure region outage.

Explanation

Correct Answer

B:

Critical dependencies can negate apparent multi-region frontend redundancy.

Incorrect Answers

A:

Front Door handles application routing, not database transactional replication. In the present requirement, an active-active regional design uses a shared external service that exists only in the primary region. The needed design instead works because critical dependencies can negate apparent multi-region frontend redundancy.

C:

Loss of shared secrets or configuration can disable both frontends. This proposal contradicts the stated architecture constraint.

D:

Regional distribution cannot cover loss of its own region. In the present requirement, an active-active regional design uses a shared external service that exists only in the primary region. The needed design instead works because critical dependencies can negate apparent multi-region frontend redundancy.

Question 602
