The answer is that the audit is configured to capture only successful operations, which is why some DELETE operations are not being audited in Azure SQL Database. Azure SQL Database auditing allows you to filter log collection by operation outcome, choosing to capture only successful operations, only failed operations, or both. When set to capture only successful operations, any DELETE that fails—due to permission errors, constraint violations, or deadlocks—is silently excluded from the audit logs, matching the scenario where some deletes are missing. On the DP-300 exam, this tests your understanding of audit action groups and the audit log filter settings under the “Audit” blade in the Azure portal; a common trap is assuming that enabling auditing automatically logs all operations regardless of outcome. Remember the memory tip: “Success-only skips the fails”—if you see missing deletes, check whether the audit filter is set to log only successful events.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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.
Your company uses Azure SQL Database and needs to audit all data modifications (INSERT, UPDATE, DELETE) for compliance. You enable SQL Database auditing and configure a storage account for logs. However, you notice that some DELETE operations are not being audited. What could be the cause?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The audit is configured to capture only successful operations.
Option C is correct because Azure SQL Database auditing can be configured to capture only successful operations or only failed operations, or both. If the audit is set to capture only successful operations, DELETE operations that fail (e.g., due to permissions or constraint violations) will not be logged. The question states that some DELETE operations are missing, which aligns with a filter that excludes failed 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.
✗
The diagnostic setting is configured incorrectly.
Why it's wrong here
Incorrect: Diagnostic settings are for metrics and logs, not audit records.
✗
The storage account firewall is blocking the audit logs.
Why it's wrong here
Incorrect: If logs are written, firewall is not the issue; the problem is missing operations.
✓
The audit is configured to capture only successful operations.
Why this is correct
Correct: Auditing can be set to capture both success and failure; if only success, some operations may not be logged if they fail.

✗
The database has Transparent Data Encryption (TDE) enabled.
Why it's wrong here
Incorrect: TDE does not affect auditing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume all data modification operations are always audited by default, overlooking that Azure SQL Database auditing allows filtering by operation outcome (success/failure), which can cause specific operations to be omitted from logs.
Detailed technical explanation
How to think about this question
Azure SQL Database auditing uses server-level and database-level audit policies, where the AUDIT_SPECIFICATION defines the action groups (e.g., DATABASE_OPERATION_GROUP) and the filter predicate (e.g., SUCCESS or FAILURE). The audit log is written synchronously or asynchronously to the configured destination; if the filter is set to 'SUCCESS_ONLY', only successful operations are recorded, and failed operations (including failed DELETEs) are silently dropped. In a compliance scenario, missing DELETE logs often indicate that the audit specification is filtering on success, or that the operations are being performed by a user or application that bypasses the audit (e.g., using a different connection string or a service principal with different permissions).

Key takeaway

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.

Variation 1. Your organization has a regulatory requirement to audit all data modifications in an Azure SQL Database. You enable Azure SQL Database auditing and configure it to send logs to a Log Analytics workspace. However, you notice that DELETE operations on a specific table are not being audited. What is the most likely cause?
medium
A.The diagnostic settings for the database are misconfigured
✓ B.The audit action group does not include 'DATABASE_OPERATION_GROUP'
C.Audit logs are being written to a storage account instead of Log Analytics
D.The table has been configured to ignore auditing for read operations
Why B: Azure SQL Database auditing uses audit action groups to define which operations are logged. By default, the audit policy includes 'SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP', 'FAILED_DATABASE_AUTHENTICATION_GROUP', and 'BATCH_COMPLETED_GROUP', but 'DATABASE_OPERATION_GROUP' is required to capture DDL and DML operations like DELETE. If this group is not explicitly added to the audit specification, DELETE operations on specific tables will not be recorded, even though general auditing is enabled.
