Microsoft AZ-305 Practice Test 38
Question 370
An Azure lake holds sensitive department data in folders and needs large-scale directory renames. Which TWO features should be used? (Select TWO.)
- Enable hierarchical namespace for Azure Data Lake Storage Gen2.
- Give every analyst account-wide Storage Blob Data Owner rights.
- Apply folder-level ACLs and suitable data-plane role assignments.
- Copy every file to the client to simulate each directory rename.
- Use only blob-name prefixes and assume they enforce POSIX directory ACLs.
Explanation
Correct Answers
A:HNS supplies directory semantics and efficient namespace operations.
C:Directory permissions restrict sensitive paths.
Incorrect Answers
B:Account-wide ownership overexposes unrelated folders.
D:Client-side copying introduces avoidable cost and partial operations.
E:Flat object prefixes do not create ACL-capable HNS directories.
Question 371
An architecture proposal for azure data lake storage gen2 relies on the following approach: Use flat Blob paths and assume directory ACL behavior exists automatically. Which specific failure or mismatch should the design reviewer identify?
- Client-side moves increase cost and introduce long partial states.
- A broad rule may delete regulated evidence prematurely.
- Flat namespace naming is not equivalent to HNS directory authorization.
- Broad account access overreaches data classification boundaries.
Explanation
Correct Answer
C:Use flat Blob paths and assume directory ACL behavior exists automatically. Flat namespace naming is not equivalent to HNS directory authorization.
Incorrect Answers
A:That assessment refers to the separate proposal 'Download and reupload every child blob to simulate a rename.' not to the recommendation under review. Here, Flat namespace naming is not equivalent to HNS directory authorization.
B:This concern applies to Apply one unconditional deletion rule across the whole account. in another design data storage solutions for semi-structured and unstructured data design. The current proposal specifically fails because flat namespace naming is not equivalent to HNS directory authorization.
D:That assessment refers to the separate proposal 'Grant all analysts Storage Blob Data Owner on the entire account.' not to the recommendation under review. Here, Flat namespace naming is not equivalent to HNS directory authorization.
Question 372
Acceptance testing must establish the following operational result: A directory permission check demonstrates data lake namespace enforcement. Which verification action most directly establishes that outcome?
- Test each team's access to approved and forbidden paths.
- Rename a large representative directory and inspect path consistency.
- Test folder-level ACLs for a user with limited rights.
- Compare rule eligibility for tagged evidence and transient sample objects.
Explanation
Correct Answer
C:A directory permission check demonstrates data lake namespace enforcement.
Incorrect Answers
A:That verification addresses the different requirement: Finance and marketing data must be separated within one data lake while pipelines share storage. It does not directly establish a directory permission check demonstrates data lake namespace enforcement.
B:That verification addresses the different requirement: A data engineering job must rename huge directories atomically rather than copy every object. It does not directly establish a directory permission check demonstrates data lake namespace enforcement.
D:This is a test for One container includes regulatory evidence and disposable images with different retention. The requirement here is instead demonstrated by test folder-level ACLs for a user with limited rights.
Question 373
A data engineering job must rename huge directories atomically rather than copy every object. Which Azure architecture choice best meets this requirement?
- Use flat Blob paths and assume directory ACL behavior exists automatically.
- Grant all analysts Storage Blob Data Owner on the entire account.
- Use supported ADLS Gen2 hierarchical namespace rename operations.
- Download and reupload every child blob to simulate a rename.
Explanation
Correct Answer
C:Hierarchical namespace supports server-side directory operations appropriate for data lakes.
Incorrect Answers
A:Flat namespace naming is not equivalent to HNS directory authorization. In the present requirement, a data engineering job must rename huge directories atomically rather than copy every object. The needed design instead works because hierarchical namespace supports server-side directory operations appropriate for data lakes.
B:Broad account access overreaches data classification boundaries. In the present requirement, a data engineering job must rename huge directories atomically rather than copy every object. The needed design instead works because hierarchical namespace supports server-side directory operations appropriate for data lakes.
D:Client-side moves increase cost and introduce long partial states. This proposal contradicts the stated architecture constraint.
Question 374

- Flat namespace naming is not equivalent to HNS directory authorization.
- Client-side moves increase cost and introduce long partial states.
- Broad account access overreaches data classification boundaries.
- One partition key value concentrates writes and can hit physical or logical limits.
Explanation
Correct Answer
B:Download and reupload every child blob to simulate a rename. Client-side moves increase cost and introduce long partial states.
Incorrect Answers
A:That assessment refers to the separate proposal 'Use flat Blob paths and assume directory ACL behavior exists automatically.' not to the recommendation under review. Here, Client-side moves increase cost and introduce long partial states.
C:That assessment refers to the separate proposal 'Grant all analysts Storage Blob Data Owner on the entire account.' not to the recommendation under review. Here, Client-side moves increase cost and introduce long partial states.
D:This concern applies to Use one constant tenant ID for every globally distributed order. in another design data storage solutions for semi-structured and unstructured data design. The current proposal specifically fails because client-side moves increase cost and introduce long partial states.
Question 375
Acceptance testing must establish the following operational result: Observed atomic behavior validates the selected namespace capability. Which verification action most directly establishes that outcome?
- Rename a large representative directory and inspect path consistency.
- Examine normalized RU consumption and hot partition metrics during load.
- Test each team's access to approved and forbidden paths.
- Test folder-level ACLs for a user with limited rights.
Explanation
Correct Answer
A:Observed atomic behavior validates the selected namespace capability.
Incorrect Answers
B:This is a test for A global customer-order collection has hot writes concentrated under one partition key. The requirement here is instead demonstrated by rename a large representative directory and inspect path consistency.
C:That verification addresses the different requirement: Finance and marketing data must be separated within one data lake while pipelines share storage. It does not directly establish observed atomic behavior validates the selected namespace capability.
D:That verification addresses the different requirement: An analytics platform needs hierarchical folders and POSIX-style access controls over files. It does not directly establish observed atomic behavior validates the selected namespace capability.
Question 376
