The correct answer is to configure a lifecycle management policy on the Azure Storage account that stores the audit logs. This works because Azure SQL Database audit logs are written as blobs to an Azure Storage account, and while the database itself has a retention setting for how long audit records are kept in the audit log, that setting does not automatically delete the underlying blob files from storage. Storage lifecycle management rules allow you to define actions such as deleting blobs older than a specified number of days, which directly addresses the need to automatically delete old audit logs and reduce storage costs. On the DP-300 exam, this question tests your understanding of the separation between database-level audit retention and storage-level lifecycle management—a common trap is assuming the SQL audit retention policy handles physical deletion. Remember the key distinction: SQL retains the record, Storage deletes the file. Memory tip: think "SQL for the log, Storage for the cleanup."
DP-300 Practice Question: Monitor, configure, and optimize database resources
This DP-300 practice question tests your understanding of monitor, configure, and optimize database 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.
You manage an Azure SQL Database with the Premium service tier. You need to reduce storage costs by automatically deleting old audit logs that are older than 90 days. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a lifecycle management policy on the Azure Storage account that stores the audit logs.
Option B is correct because Azure SQL Database audit logs are stored in Azure Storage and a retention policy can be set on the storage account to automatically delete blobs after a specified number of days. Option A is wrong because the audit retention policy in SQL Database is only for the number of days to retain audit records, but it does not automatically delete from storage; deletion is handled by storage lifecycle management. Option C is wrong because Extended Events are not the primary method for audit log cleanup. Option D is wrong because backup retention is unrelated to audit logs.
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.
✗
Create an Extended Events session that filters and deletes old audit events.
Why it's wrong here
Extended Events do not manage retention of stored audit logs.
✗
Reduce the backup retention period to 90 days.
Why it's wrong here
Backup retention is separate from audit log retention.
✗
Set the audit retention policy to 90 days in the server's audit settings.
Why it's wrong here
This only controls how long audit records are kept in the database, not deletion from storage.
✓
Configure a lifecycle management policy on the Azure Storage account that stores the audit logs.
Why this is correct
Automatically deletes blobs older than 90 days.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
