What is the default time range in Performance Hub?

Performance Hub in Autonomous Database provides performance monitoring insights. The correct

answer is:

24 Hours (C): When you open Performance Hub in the OCI console or Database Actions, the default

time range displayed is the last 24 hours, shown in Coordinated Universal Time (UTC). This allows

users to review recent performance metrics like CPU usage, SQL activity, and wait times. Users can

adjust this range (e.g., to 1 hour or 1 week) as needed.

The incorrect options are:

15 Minutes (A): This is not a default option; it’s too short for a broad performance overview.

1 Hour (B): Available as an option, but not the default setting.

1 Week (D): Also available, but not the default; it’s a longer-term view users can select manually.

The 24-hour default balances recency and context for performance analysis.
