Oracle Autonomous Database Cloud 2023 Specialist Questions and Answers

Question 1

Autonomous Database's auto scaling feature allows your database to use up to three times the current base number of CPU 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?

Options:

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 meet high-load demands.

The base number of OCPU cores allocated to a database is not guaranteed.

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.

Auto scaling is enabled by default and can be enabled or disabled at any time.
