An administrator enabled diagnostic settings on an Azure Storage account using the resource-specific schema. A coworker then ran a query against AzureDiagnostics and got no rows, even though failed blob writes occurred during the last hour. What is the best fix?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Switch the diagnostic setting back to the legacy AzureDiagnostics schema so all logs land there.
That would work only by reverting the schema choice, but it is not the best troubleshooting fix here.
B
Best answer
Query the storage account's dedicated resource-specific log table and filter for failed write operations.
When resource-specific diagnostic mode is enabled, logs no longer land in AzureDiagnostics for that resource. The correct action is to query the dedicated storage log table produced by the diagnostic setting, then filter for the failed write status and time window. This aligns the query with the actual schema that is collecting the data.
C
Distractor review
Use the Azure Activity log because blob write failures are always control-plane events.
Blob write failures are data-plane events, so the Activity log will not contain the needed request details.
D
Distractor review
Create a metric alert on storage capacity because that metric includes failed requests.
Capacity metrics do not reveal operation-level failure details such as request status codes or write errors.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Query the storage account's dedicated resource-specific log table and filter for failed write operations. — The key issue is the log schema. With resource-specific diagnostic settings, Azure writes data into dedicated tables rather than the legacy AzureDiagnostics table. A query aimed at AzureDiagnostics will return nothing if that schema is not being used. To troubleshoot failed blob writes, the administrator should query the storage-specific table and filter for failed operations within the desired time range. That matches the way the data is actually stored. Why others are wrong: Reverting to the legacy schema is possible in some environments, but it is a workaround rather than the best fix for the current query problem. The Activity log records control-plane operations, not blob request failures. Storage capacity metrics do not include per-request error detail, so they cannot answer this troubleshooting question. The schema and table selection must match the diagnostic configuration.
