Practice Test 1 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
You are working as an AWS Architect for a start-up company. They have a production website which is two-tier with web servers in front end & database servers in the back end. All these database servers are spread across multiple Availability Zones & are the stateful instances. You have configured Auto Scaling Group for these servers with a minimum of 2 instances & maximum of 6 instances. During scale in of these instances, post-peak hours, you are observing data loss from these database servers. Which feature needs to be configured additionally to avoid data loss & copy data before instance termination?
A. Modify the cooldown period to complete custom actions before the Instance terminates
B. Add lifecycle hooks to Auto Scaling group
C. Customize Termination policy to complete data copy before termination.
D. Suspend Terminate process that will avoid data loss
Explanation:
Correct Answer – B
Explanation: Adding Lifecycle Hooks to Auto Scaling group puts the instance into wait state before termination. During this wait state, you can perform custom activities to retrieve critical operational data from a stateful instance. Default Wait period is 1 hour.
- Option A is incorrect as the cooldown period will not help to copy data from the instance before termination.
- Option C is incorrect as Termination policy is used to specify which instances to terminate first during scale in, configuring termination policy for the Auto Scaling group will not copy data before instance termination.
- Option D is incorrect as Suspending Terminate policy will not prevent data loss but will disrupt other process & prevent scale in.
