- A
Switch the diagnostic setting back to the legacy AzureDiagnostics schema so all logs land there.
Why wrong: That would work only by reverting the schema choice, but it is not the best troubleshooting fix here.
- B
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
Use the Azure Activity log because blob write failures are always control-plane events.
Why wrong: Blob write failures are data-plane events, so the Activity log will not contain the needed request details.
- D
Create a metric alert on storage capacity because that metric includes failed requests.
Why wrong: Capacity metrics do not reveal operation-level failure details such as request status codes or write errors.
AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Query the storage account's dedicated resource-specific log table and filter for failed write operations.
When a diagnostic setting is configured with the resource-specific schema, Azure routes logs to dedicated tables (e.g., StorageBlobLogs) rather than the legacy AzureDiagnostics table. Querying AzureDiagnostics returns no rows because the logs are not stored there. The correct fix is to query the appropriate resource-specific log table (e.g., StorageBlobLogs) and filter for failed write operations, as this table contains the detailed, schema-specific data for the storage account's blob operations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switch the diagnostic setting back to the legacy AzureDiagnostics schema so all logs land there.
Why it's wrong here
That would work only by reverting the schema choice, but it is not the best troubleshooting fix here.
When this WOULD be correct
If the diagnostic setting was configured with the 'Send to Log Analytics workspace' destination and the 'AzureDiagnostics' schema (legacy mode), then querying AzureDiagnostics would be correct. This option is correct when the diagnostic setting explicitly uses the legacy schema.
- ✓
Query the storage account's dedicated resource-specific log table and filter for failed write operations.
Why this is correct
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.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Use the Azure Activity log because blob write failures are always control-plane events.
Why it's wrong here
Blob write failures are data-plane events, so the Activity log will not contain the needed request details.
When this WOULD be correct
This option would be correct if the question asked about a control-plane operation, such as 'A user failed to create a new storage account' or 'An administrator deleted a storage account.' In those cases, the Activity log would contain the relevant failure events.
- ✗
Create a metric alert on storage capacity because that metric includes failed requests.
Why it's wrong here
Capacity metrics do not reveal operation-level failure details such as request status codes or write errors.
When this WOULD be correct
If the question asked for a way to be notified when storage account capacity exceeds a threshold (e.g., 80% full), creating a metric alert on the 'Used Capacity' metric would be the correct solution.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Query the storage account's dedicated resource-specific log table and filter for failed write operations.Correct answer▾
Why this is correct
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.
✗Switch the diagnostic setting back to the legacy AzureDiagnostics schema so all logs land there.Wrong answer — click to see why▾
Why this is wrong here
When resource-specific schema is enabled, logs are sent to dedicated tables (e.g., StorageBlobLogs), not to AzureDiagnostics. Querying AzureDiagnostics returns no rows because logs are no longer stored there.
★ When this WOULD be the correct answer
If the diagnostic setting was configured with the 'Send to Log Analytics workspace' destination and the 'AzureDiagnostics' schema (legacy mode), then querying AzureDiagnostics would be correct. This option is correct when the diagnostic setting explicitly uses the legacy schema.
Why candidates choose this
Candidates may be familiar with the legacy AzureDiagnostics table and assume all Azure logs land there, not realizing that resource-specific tables are used when that schema is selected.
✗Use the Azure Activity log because blob write failures are always control-plane events.Wrong answer — click to see why▾
Why this is wrong here
Blob write failures are data-plane events, not control-plane events. The Azure Activity log only captures control-plane operations (e.g., creating a storage account), not data-plane operations like blob writes.
★ When this WOULD be the correct answer
This option would be correct if the question asked about a control-plane operation, such as 'A user failed to create a new storage account' or 'An administrator deleted a storage account.' In those cases, the Activity log would contain the relevant failure events.
Why candidates choose this
Candidates may confuse control-plane and data-plane operations, or mistakenly think that all Azure failures are logged in the Activity log, especially when they are unfamiliar with diagnostic settings and resource-specific tables.
✗Create a metric alert on storage capacity because that metric includes failed requests.Wrong answer — click to see why▾
Why this is wrong here
Metric alerts on storage capacity do not include failed requests; they monitor capacity metrics like used storage. Failed blob writes are data-plane operations logged in diagnostic logs, not captured by capacity metrics.
★ When this WOULD be the correct answer
If the question asked for a way to be notified when storage account capacity exceeds a threshold (e.g., 80% full), creating a metric alert on the 'Used Capacity' metric would be the correct solution.
Why candidates choose this
Candidates may confuse 'metric alerts' with 'log alerts' or think that capacity metrics aggregate all request failures, not realizing that capacity metrics only track storage usage, not operation outcomes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume all diagnostic logs land in the AzureDiagnostics table by default, overlooking that the resource-specific schema redirects logs to dedicated tables, leading them to incorrectly choose Option A or fail to query the correct table.
Detailed technical explanation
How to think about this question
The resource-specific schema in Azure Monitor diagnostic settings creates separate tables per resource type (e.g., StorageBlobLogs, StorageQueueLogs) with columns tailored to that resource's operations. This schema reduces query complexity and cost compared to the legacy AzureDiagnostics table, which aggregates all resource logs into a single wide table with a ResourceType column for filtering. In a real-world scenario, if you need to audit failed blob writes for compliance, you would query StorageBlobLogs with a filter like StatusCode >= 400 and OperationName == 'PutBlob' to isolate failures efficiently.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
