Oracle Cloud Infrastructure Foundations 2020 Associate — Question 58

What does compute instance horizontal scaling mean?

Answer options

• A. adding additional compute instances
• B. changing compute instance size
• C. backing up data to object storage
• D. stopping/starting the instance

Correct answer: A

Explanation

Horizontal scaling refers to the process of adding more compute instances to handle increased workload, which is why option A is correct. Option B describes vertical scaling, which involves changing the size of existing instances. Option C relates to data management rather than scaling, and option D is about managing instance states, not scaling.
