Question 820

A multi-year move involves 300 applications and must prioritize low-risk workloads first. Which Azure architecture choice best meets this requirement?

  1. Migrate every business-critical app in one untested overnight cutover.
  2. Use Cloud Adoption Framework assessment and migration waves based on dependencies and risk.
  3. Declare success solely after the source VM is powered off.
  4. Let each application improvise a public IP and unrestricted subnet.

Explanation

Correct Answer

B:

Landing-zone readiness and wave planning reduce combined blast radius.

Incorrect Answers

A:

One big-bang move magnifies dependency and recovery risk. This proposal contradicts the stated architecture constraint.

C:

The service might still be slower, riskier or more expensive than planned. In the present requirement, a multi-year move involves 300 applications and must prioritize low-risk workloads first. The needed design instead works because landing-zone readiness and wave planning reduce combined blast radius.

D:

Decentralized emergency defaults create inconsistent security exposure. In the present requirement, a multi-year move involves 300 applications and must prioritize low-risk workloads first. The needed design instead works because landing-zone readiness and wave planning reduce combined blast radius.

Question 821

An architecture proposal for cloud adoption framework migration waves relies on the following approach: Migrate every business-critical app in one untested overnight cutover. Which specific failure or mismatch should the design reviewer identify?

  1. Full retransmission wastes time and network cost.
  2. Decentralized emergency defaults create inconsistent security exposure.
  3. The service might still be slower, riskier or more expensive than planned.
  4. One big-bang move magnifies dependency and recovery risk.

Explanation

Correct Answer

D:

Migrate every business-critical app in one untested overnight cutover. One big-bang move magnifies dependency and recovery risk.

Incorrect Answers

A:

This concern applies to Force a blind full-copy of unchanged historical data each run. in another design migrations design. The current proposal specifically fails because one big-bang move magnifies dependency and recovery risk.

B:

That assessment refers to the separate proposal 'Let each application improvise a public IP and unrestricted subnet.' not to the recommendation under review. Here, One big-bang move magnifies dependency and recovery risk.

C:

That assessment refers to the separate proposal 'Declare success solely after the source VM is powered off.' not to the recommendation under review. Here, One big-bang move magnifies dependency and recovery risk.

Question 822

Acceptance testing must establish the following operational result: Pilot evidence supports controlled expansion. Which verification action most directly establishes that outcome?

  1. Deploy a test migrated workload and inspect inherited policies and routes.
  2. Track availability, spend and application experience after cutover.
  3. Run two transfers with one changed object and inspect transferred set.
  4. Measure wave exit criteria and rollback readiness after a pilot.

Explanation

Correct Answer

D:

Pilot evidence supports controlled expansion.

Incorrect Answers

A:

That verification addresses the different requirement: Migration teams work quickly but cannot apply consistent network security or subscription governance. It does not directly establish pilot evidence supports controlled expansion.

B:

That verification addresses the different requirement: A migration completes technically but the company cannot demonstrate intended operating cost or resilience. It does not directly establish pilot evidence supports controlled expansion.

Question 829

Several app VNets need controlled access to shared DNS and firewall services. Which Azure architecture choice best meets this requirement?

  1. Reuse the same RFC1918 subnet in every VNet and assume peering resolves it.
  2. Place every VNet into one flat address range with overlapping subnets.
  3. Assume A-B and B-C peering automatically create A-C transit.
  4. Design hub-and-spoke VNets with deliberate peering and central routing.

Explanation

Correct Answer

D:

A shared hub supports governed services without duplicating every appliance.

Incorrect Answers

A:

Address overlaps complicate or prevent VNet peering and route distinction. In the present requirement, several app VNets need controlled access to shared DNS and firewall services. The needed design instead works because a shared hub supports governed services without duplicating every appliance.

B:

Overlap prevents straightforward routed reachability and scaling. This proposal contradicts the stated architecture constraint.

C:

Nontransitive VNet peering does not create a full routing mesh. In the present requirement, several app VNets need controlled access to shared DNS and firewall services. The needed design instead works because a shared hub supports governed services without duplicating every appliance.

Question 830
