Oracle Cloud Infrastructure 2020 Architect Associate — Question 40

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? (Choose the best answer.)

Answer options

• A. The base number of OCPU cores allocated to a database is not guaranteed.
• B. Auto scaling is enabled by default and can be enabled or disabled at any time.
• C. 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.
• D. 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.

Correct answer: A

Explanation

The statement in option A is incorrect because the base number of OCPU cores allocated to a database is indeed guaranteed. Option B is true as auto scaling is enabled by default. Option C is accurate as it describes the limitation based on available free cores. Option D is also correct since it explains how the total number of cores in Exadata infrastructure affects availability.
