An architect proposes relying only on EBS snapshots to claim multi-AZ high availability for a running EC2 database volume. What is the correct distinction?
Select an answer to reveal the explanation.
Short Explanation
Snapshots are great seatbelts for restore—they don’t make one AZ volume magically run in three AZs at once. Live HA and backup RPO are different tools.
Full Explanation
EBS volumes are tied to a single AZ; snapshots provide durable backups that aid RPO when restoring, but they do not keep a live volume highly available across AZs. Multi-AZ database services or multi-AZ application designs address live AZ failure; snapshot restore is not zero-RTO automatic failover of the original volume.
