DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing

You are monitoring an Azure Data Factory pipeline that runs hourly. The pipeline executes a stored procedure in an Azure SQL Database. Recently, you have observed that the pipeline occasionally fails with a 'Deadlock' error when the stored procedure runs. The Azure SQL Database is configured with the 'Read Committed Snapshot' isolation level enabled. You need to resolve the deadlock issue with minimal impact on performance. The stored procedure updates multiple tables in a single transaction and is critical for reporting. What should you do?

⚠ Common exam trap

DP-203 often tests the misconception that disabling RCSI or adding NOLOCK will fix deadlocks — in reality deadlocks are transient and the correct minimal-impact fix is retry logic, not isolation-level changes.

Correct answer & explanation

✓

Add retry logic in the Data Factory pipeline for the stored procedure activity

Adding retry logic in the Data Factory pipeline for the stored procedure activity is the least invasive fix. Deadlocks are transient by nature — SQL Server chooses a victim and rolls back its transaction — so retrying the activity typically succeeds on the next attempt without changing isolation levels or query semantics.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Change the stored procedure to use NOLOCK hints

    Why it's wrong here

    NOLOCK hints apply only to SELECT statements, yet the deadlock arises from the procedure's multi-table updates, so dirty reads are introduced without resolving write-write contention. NOLOCK suits read-only reporting queries tolerating uncommitted data, not transactional writers.

  • ✗

    Remove the transaction from the stored procedure

    Why it's wrong here

    Removing the transaction breaks atomicity across the multiple table updates the reporting procedure requires, leaving partial data on failure while deadlocks can still occur between individual statements. It suits independent statements where consistency across tables is unnecessary.

  • ✓

    Add retry logic in the Data Factory pipeline for the stored procedure activity

    Why this is correct

    Retry logic in the Data Factory activity handles transient deadlock failures without altering the stored procedure's transaction semantics or isolation level. Since the procedure updates multiple tables in one transaction and is critical for reporting, retrying the activity preserves Read Committed Snapshot behaviour and avoids performance penalties, satisfying the minimal-impact constraint.

  • ✗

    Disable the 'Read Committed Snapshot' isolation level

    Why it's wrong here

    Disabling Read Committed Snapshot makes readers take shared locks, so they block writers and worsen the deadlock cycle rather than breaking it. RCSI was likely enabled to reduce blocking; removing it reintroduces reader-writer contention. It would suit a workload where snapshot overhead or tempdb pressure must be eliminated, not a deadlock fix.
