When activating a disaster recovery site, which action should typically be performed FIRST?
Answer: Declaring a disaster and invoking the DR plan
Formally declaring a disaster and invoking the DR plan initiates the structured response process, including stakeholder notification, resource mobilization, and system recovery.
What is 'data deduplication' and how does it benefit disaster recovery?
Answer: Eliminating redundant data copies to reduce backup storage and replication bandwidth
Data deduplication identifies and removes redundant data blocks, significantly reducing storage requirements and accelerating replication to DR sites.
What is the role of an 'emergency change management process' during technology recovery?
Answer: To allow expedited changes needed to restore systems while maintaining documentation and accountability
An emergency change management process streamlines approvals during a crisis while still capturing changes made, preserving auditability and enabling accurate post-incident review.
Which of the following best describes 'active-active' disaster recovery?
Answer: Both sites simultaneously process live workloads and can absorb the other's traffic on failure
Active-active configurations run live workloads across two or more sites simultaneously, providing instant failover with no recovery time needed when one site fails.
Why is it important to validate recovery procedures after a significant infrastructure change?
Answer: To ensure procedures remain accurate and recovery capabilities are not degraded by the change
Infrastructure changes can invalidate existing recovery procedures, so re-testing after changes ensures the documented steps still work in the updated environment.
What is the primary concern when using asynchronous replication for disaster recovery?
Answer: There may be a lag between the primary and replica, resulting in potential data loss equal to the replication delay
Asynchronous replication does not wait for acknowledgment from the replica before completing a write, so a failure during the lag window results in data loss.
In technology recovery, what is meant by 'system hardening' as part of DR preparation?
Answer: Reducing attack surface and vulnerabilities on recovery systems so they are secure when activated
System hardening applies security configurations to recovery systems to prevent them from being exploited when activated, since DR environments are sometimes less routinely patched.
