CCSK Incident Response and Business Continuity in Cloud 2

Question 1

What does CCSK say about 'recovery time objective' (RTO) in cloud business continuity planning?

Accepted Answer

RTO defines the maximum acceptable time to restore services after an incident, which cloud architectures should be designed to meet

Answer

RTO defines how quickly services must be restored; cloud architectures should be designed with automation, multi-region failover, and runbooks to meet defined RTO targets.

Question 2

What is the difference between 'backup' and 'replication' in cloud disaster recovery?

Accepted Answer

Backup creates point-in-time copies for restoration; replication continuously synchronizes data to another location for rapid failover

Answer

Backups provide recoverable snapshots at a point in time, while replication maintains a live synchronized copy to minimize data loss and enable rapid failover.

Question 3

According to CCSK, what is 'chaos engineering' and how does it benefit cloud resilience?

Accepted Answer

Deliberately introducing failures into production systems to identify weaknesses before they cause unplanned outages

Answer

Chaos engineering proactively tests system resilience by intentionally injecting failures (instance termination, network disruption) to identify weaknesses under controlled conditions.

Question 4

What is a 'warm standby' disaster recovery pattern in cloud environments?

Accepted Answer

A scaled-down but running replica of the production environment that can be quickly scaled up for failover

Answer

Warm standby maintains a minimally scaled running environment that mirrors production, enabling faster recovery than cold standby but at lower cost than hot standby.

Question 5

According to CCSK, what should organizations test to validate their cloud business continuity plans?

Accepted Answer

Full failover scenarios including switching to DR environments, validating RTOs, and testing personnel procedures

Answer

BCP validation requires testing complete failover scenarios, verifying that RTO/RPO objectives are met, and ensuring personnel can execute procedures under real conditions.
