Alibaba Cloud Certified Associate – Cloud Computing — Question 18

Auto Scaling can automatically remove unhealthy ECS instances from the scaling group (this feature is called Elastic Self-Health). Yet, after removal, the user has to manually add equivalent amount of new ECS instances back to the scaling group.

Answer options

• A. TRUE
• B. FALSE

Correct answer: B

Explanation

The correct answer is FALSE because Auto Scaling can automatically launch new instances to replace the unhealthy ones, thus eliminating the need for manual intervention. Therefore, users do not have to manually add new ECS instances after an unhealthy instance is removed.
