Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Edit the SPFILE to change the statistics_level to 'BASIC'.
Why it's wrong here
Setting statistics_level to BASIC disables AWR entirely, which is not the same as modifying the interval.
- ✓
Use the DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS procedure.
Why this is correct
This is the correct administrative interface for AWR configuration.
- ✗
Update the SGA_TARGET parameter.
Why it's wrong here
SGA_TARGET manages memory allocation, not diagnostic repository intervals.
- ✗
Manually delete old records from the DBA_HIST_SNAPSHOT view.
Why it's wrong here
Modifying AWR tables directly is unsupported and dangerous; use provided PL/SQL packages.
