During a DR test, which snapshot is used when 'activate' is checked on the remote site’s production domain?

1. The oldest protection domain snapshot

2. The newest protection domain snapshot at the remote site

3. The most recent snapshot from the local site

4. The first snapshot taken during the replication period

The correct answer is: The newest protection domain snapshot at the remote site

When 'activate' is checked on the remote site’s production domain during a disaster recovery (DR) test, the newest protection domain snapshot at the remote site is utilized. The rationale behind this is that selecting the most recent snapshot ensures that the data being activated is the latest version, capturing all changes and updates that occurred up to that point before the failover takes place. Using the newest snapshot provides a more current view of the system, which is critical during DR scenarios. It mitigates risks associated with data loss and ensures continuity by maintaining the integrity of the latest data, thus allowing applications and services to resume operations seamlessly after a disaster event. In contrast, relying on an older snapshot could result in potential inconsistencies and loss of vital information that might have been captured after the older snapshot was taken. Therefore, the strategy of using the most recent snapshot aligns with best practices in disaster recovery, emphasizing the importance of having up-to-date backups for quick recovery.
