Oracle Cloud Infrastructure 2023 Architect Associate — Question 20

Autonomous Database's auto scaling feature allows your database to use up to three times the current base number of OCPU cores at any time. As demand increases, auto scaling automatically increases the number of cores in use. Likewise, as demand drops, auto scaling automatically decreases the number of cores in use.

Which statement is FALSE regarding the auto scaling feature?

Answer options

• A. For databases on dedicated Exadata infrastructure, the maximum number of cores available to a database depends on the total number of cores available in the Exadata infrastructure instance.
• B. Auto scaling is enabled by default and can be enabled or disabled at any time.
• C. The base number of OCPU cores allocated to a database is not guaranteed.
• D. For databases on dedicated Exadata infrastructure, the maximum number of cores is limited by the number of free cores that aren’t being used by other auto scaling databases to sheet high-load demands.

Correct answer: B

Explanation

The correct answer is B because auto scaling is not enabled by default; it must be explicitly configured. The other statements are true: the maximum number of cores is based on infrastructure capacity (A), the base OCPU allocation is not guaranteed (C), and the limits on cores depend on other databases' usage (D).
