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
✓
Enabling snapshot isolation
Implementing snapshot isolation (or read-committed snapshot isolation) allows readers to access the versioned data without blocking writers, significantly reducing contention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switching to an asynchronous commit model
Why it's wrong here
Asynchronous commit affects replication, not local lock contention.
- ✗
Increasing the memory allocation for the buffer pool
Why it's wrong here
Memory increases don't resolve row-level lock contention.
- ✓
Enabling snapshot isolation
Why this is correct
Snapshot isolation uses row versioning to allow reads to proceed without waiting for write locks.
- ✗
Dropping all non-clustered indexes
Why it's wrong here
Dropping indexes would cause severe performance degradation for queries.
