AWS Certified SysOps Administrator – Associate (legacy) — Question 307

An organization has configured two single availability zones. The Auto Scaling groups are configured in separate zones. The user wants to merge the groups such that one group spans across multiple zones. How can the user configure this?

Answer options

• A. Run the command as-join-auto-scaling-group to join the two groups
• B. Run the command as-update-auto-scaling-group to configure one group to span across zones and delete the other group
• C. Run the command as-copy-auto-scaling-group to join the two groups
• D. Run the command as-merge-auto-scaling-group to merge the groups

Correct answer: B

Explanation

To consolidate two Auto Scaling groups into one that spans multiple zones, you must modify one of the groups using the as-update-auto-scaling-group command to include the additional Availability Zone, and then delete the redundant group. AWS Auto Scaling does not support native commands for joining, merging, or copying groups directly, making options A, C, and D incorrect. This manual adjustment ensures that a single group manages instances across both Availability Zones seamlessly.
