Microsoft AZ-305 Practice Test 78
Question 770
An architecture proposal for azure migrate discovery and sizing relies on the following approach: Size the target from the previous hour of minimal utilization only. Which specific failure or mismatch should the design reviewer identify?
- Storage path and endpoint dependencies require explicit migration design.
- A short idle window misses critical workload spikes.
- Unplanned sequence can strand database-dependent applications.
- Size-only extrapolation ignores utilization and dependencies.
Explanation
Correct Answer
B:Size the target from the previous hour of minimal utilization only. A short idle window misses critical workload spikes.
Incorrect Answers
A:This concern applies to Assume the appliance automatically repairs every application connection string. in another design migrations design. The current proposal specifically fails because a short idle window misses critical workload spikes.
C:That assessment refers to the separate proposal 'Move servers in arbitrary alphabetical order without testing interdependencies.' not to the recommendation under review. Here, A short idle window misses critical workload spikes.
D:That assessment refers to the separate proposal 'Estimate every workload as the same VM size using only server count.' not to the recommendation under review. Here, A short idle window misses critical workload spikes.
Question 771
Acceptance testing must establish the following operational result: Observed usage proves the sizing covers business cycles. Which verification action most directly establishes that outcome?
- Validate the proposed migration wave's dependency graph.
- Review peak distribution and confidence across the assessment period.
- Compare discovered CPU, memory and disks for representative workloads.
- Test representative applications against imported data paths.
Explanation
Correct Answer
B:Observed usage proves the sizing covers business cycles.
Incorrect Answers
A:That verification addresses the different requirement: Migration sequencing is blocked by unknown communication dependencies between app and database tiers. It does not directly establish observed usage proves the sizing covers business cycles.
C:That verification addresses the different requirement: An enterprise needs to inventory 500 on-premises VMware VMs before choosing Azure targets. It does not directly establish observed usage proves the sizing covers business cycles.
D:This is a test for An offline migration arrives but required folder mappings do not match applications' new paths. The requirement here is instead demonstrated by review peak distribution and confidence across the assessment period.
Question 772
Migration sequencing is blocked by unknown communication dependencies between app and database tiers. Which Azure architecture choice best meets this requirement?
- Size the target from the previous hour of minimal utilization only.
- Use dependency analysis with Azure Migrate or complementary discovery tools.
- Move servers in arbitrary alphabetical order without testing interdependencies.
- Estimate every workload as the same VM size using only server count.
Explanation
Correct Answer
B:Dependency mapping exposes system-to-system traffic before cutover.
Incorrect Answers
A:A short idle window misses critical workload spikes. In the present requirement, migration sequencing is blocked by unknown communication dependencies between app and database tiers. The needed design instead works because dependency mapping exposes system-to-system traffic before cutover.
C:Unplanned sequence can strand database-dependent applications. This proposal contradicts the stated architecture constraint.
D:Size-only extrapolation ignores utilization and dependencies. In the present requirement, migration sequencing is blocked by unknown communication dependencies between app and database tiers. The needed design instead works because dependency mapping exposes system-to-system traffic before cutover.
Question 773
An architecture proposal for azure migrate discovery and sizing relies on the following approach: Move servers in arbitrary alphabetical order without testing interdependencies. Which specific failure or mismatch should the design reviewer identify?
- Inadequate bandwidth could miss the migration schedule.
- Size-only extrapolation ignores utilization and dependencies.
- Unplanned sequence can strand database-dependent applications.
- A short idle window misses critical workload spikes.
Explanation
Correct Answer
C:Move servers in arbitrary alphabetical order without testing interdependencies. Unplanned sequence can strand database-dependent applications.
Incorrect Answers
A:This concern applies to Use only AzCopy over the constrained link without estimating transfer time. in another design migrations design. The current proposal specifically fails because unplanned sequence can strand database-dependent applications.
B:That assessment refers to the separate proposal 'Estimate every workload as the same VM size using only server count.' not to the recommendation under review. Here, Unplanned sequence can strand database-dependent applications.
D:That assessment refers to the separate proposal 'Size the target from the previous hour of minimal utilization only.' not to the recommendation under review. Here, Unplanned sequence can strand database-dependent applications.
Question 774
Acceptance testing must establish the following operational result: The graph supports staged move groups. Which verification action most directly establishes that outcome?
- Validate the proposed migration wave's dependency graph.
- Review peak distribution and confidence across the assessment period.
- Compare discovered CPU, memory and disks for representative workloads.
- Calculate upload duration and compare Data Box shipping/copy workflow.
Explanation
Correct Answer
A:The graph supports staged move groups.
Incorrect Answers
B:That verification addresses the different requirement: A workload appears idle most of the day but has intense month-end reporting. It does not directly establish the graph supports staged move groups.
C:That verification addresses the different requirement: An enterprise needs to inventory 500 on-premises VMware VMs before choosing Azure targets. It does not directly establish the graph supports staged move groups.
D:This is a test for A remote datacenter has 300 TB to migrate but only a slow, expensive WAN link. The requirement here is instead demonstrated by validate the proposed migration wave's dependency graph.
Question 775
A supported on-premises VM must move to Azure IaaS with minimal application redesign. Which Azure architecture choice best meets this requirement?
- Select an assessed Azure Migrate server migration replication path.
- Keep the smallest OS disk and assume every VM size has unlimited IOPS.
- Rewrite the application into microservices solely to accomplish an urgent rehost.
- Delete source servers before validating their Azure replacements.
Explanation
Correct Answer
A:Rehosting preserves much of the OS and application while changing the platform.
Incorrect Answers
B:VM and disk throughput limits constrain actual performance. In the present requirement, a supported on-premises VM must move to Azure IaaS with minimal application redesign. The needed design instead works because rehosting preserves much of the OS and application while changing the platform.
C:Unnecessary refactoring adds schedule and regression risk. This proposal contradicts the stated architecture constraint.
D:Premature removal eliminates the rollback path. In the present requirement, a supported on-premises VM must move to Azure IaaS with minimal application redesign. The needed design instead works because rehosting preserves much of the OS and application while changing the platform.
Question 776
An architecture proposal for vm server migration and cutover relies on the following approach: Rewrite the application into microservices solely to accomplish an urgent rehost. Which specific failure or mismatch should the design reviewer identify?
- Premature removal eliminates the rollback path.
- Document databases do not automatically preserve SQL join semantics.
- VM and disk throughput limits constrain actual performance.
- Unnecessary refactoring adds schedule and regression risk.
Explanation
Correct Answer
D:Rewrite the application into microservices solely to accomplish an urgent rehost. Unnecessary refactoring adds schedule and regression risk.
Incorrect Answers
A:That assessment refers to the separate proposal 'Delete source servers before validating their Azure replacements.' not to the recommendation under review. Here, Unnecessary refactoring adds schedule and regression risk.
B:This concern applies to Copy relational tables into JSON and assume joins remain unchanged. in another design migrations design. The current proposal specifically fails because unnecessary refactoring adds schedule and regression risk.
