Answer: D

Explanation:

To reduce the time required for new instances to become available in an Auto Scaling group, pre-installing the necessary software in the AMI used by the Auto Scaling group is the most effective solution.

Use EC2 Image Builder:

Utilize EC2 Image Builder to create a custom AMI that includes all the required software and configurations.

This reduces the setup time during instance launch, as the user data script will no longer need to

install the software.

Reference: EC2 Image Builder

Update Auto Scaling Group:

Update the Auto Scaling group to use the new AMI with pre-installed software.

Reference: Auto Scaling Groups

This solution ensures that new instances can handle traffic more quickly, reducing latency during scaling events.
