Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run DBMS_STATS.LOCK_TABLE_STATS
Why it's wrong here
This prevents statistics updates, not plan changes.
- ✓
Use DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE
Why this is correct
This function creates a baseline from the cursor cache, locking the plan.
- ✗
Set OPTIMIZER_FEATURES_ENABLE to a previous version
Why it's wrong here
This is a global parameter, not specific to one SQL statement.
- ✗
Use SQL Tuning Advisor to accept a new profile
Why it's wrong here
This recommends new plans, it does not lock existing ones.
