Microsoft AZ-305 Practice Test 81
Question 800
An architecture proposal for azure database migration service planning relies on the following approach: Migrate rows but discard the client key configuration. Which specific failure or mismatch should the design reviewer identify?
- Unnecessary refactoring adds schedule and regression risk.
- Raw files do not provide an engine-aware cutover.
- Partial data arrival is not proof of transaction completeness.
- Encrypted values may become unusable to applications.
Explanation
Correct Answer
D:Migrate rows but discard the client key configuration. Encrypted values may become unusable to applications.
Incorrect Answers
A:This concern applies to Rewrite the application into microservices solely to accomplish an urgent rehost. in another design migrations design. The current proposal specifically fails because encrypted values may become unusable to applications.
B:That assessment refers to the separate proposal 'Use a generic file copy as if it also migrated database transactions and security.' not to the recommendation under review. Here, Encrypted values may become unusable to applications.
C:That assessment refers to the separate proposal 'Decommission the source immediately when the first target table appears.' not to the recommendation under review. Here, Encrypted values may become unusable to applications.
Question 801
Acceptance testing must establish the following operational result: Application validation confirms cryptographic dependencies survive. Which verification action most directly establishes that outcome?
- Connect with an authorized driver and decrypt representative migrated records.
- Exercise a failed acceptance scenario and a rollback decision.
- Test the replicated VM's app behavior before final cutover.
- Test data consistency and target login configuration after migration.
Explanation
Correct Answer
A:Application validation confirms cryptographic dependencies survive.
Incorrect Answers
B:That verification addresses the different requirement: A migration plan requires a fallback if the target fails acceptance tests. It does not directly establish application validation confirms cryptographic dependencies survive.
C:This is a test for A supported on-premises VM must move to Azure IaaS with minimal application redesign. The requirement here is instead demonstrated by connect with an authorized driver and decrypt representative migrated records.
D:That verification addresses the different requirement: A compatible on-premises SQL database needs transfer into a supported Azure PaaS target. It does not directly establish application validation confirms cryptographic dependencies survive.
Question 802
A company needs to move terabytes of blobs between eligible Azure storage accounts over the network. Which Azure architecture choice best meets this requirement?
- Manually download every blob through an interactive browser session.
- Assign a generic Reader role and assume it writes any blob.
- Force a blind full-copy of unchanged historical data each run.

Incorrect Answers
A:That verification addresses the different requirement: An AzCopy task fails with authorization errors even though the storage account exists. It does not directly establish verification confirms transfer completeness.
B: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 compare source and destination counts and content checksums.
D:That verification addresses the different requirement: A scheduled pipeline copies new files but should not retransmit the entire container every night. It does not directly establish verification confirms transfer completeness.
Question 805
A scheduled pipeline copies new files but should not retransmit the entire container every night. Which Azure architecture choice best meets this requirement?
- Manually download every blob through an interactive browser session.
- Force a blind full-copy of unchanged historical data each run.
- Use a supported incremental transfer strategy and reliable change detection.
- Assign a generic Reader role and assume it writes any blob.
Explanation
Correct Answer
C:Selective transfers reduce bandwidth while preserving updates.
Incorrect Answers
A:Interactive copying is inefficient and fragile for very large datasets. In the present requirement, a scheduled pipeline copies new files but should not retransmit the entire container every night. The needed design instead works because selective transfers reduce bandwidth while preserving updates.
B:Full retransmission wastes time and network cost. This proposal contradicts the stated architecture constraint.
