DRI Technology Recovery Procedures 2 — Questions and Answers
Question 1: What is the primary purpose of a technology recovery runbook?
- To document vendor contracts
- To provide step-by-step instructions for restoring systems during a disaster (Correct answer)
- To list all hardware assets
- To define employee roles during normal operations
Correct answer: To provide step-by-step instructions for restoring systems during a disaster
A technology recovery runbook provides detailed, step-by-step procedures that enable staff to restore IT systems during a disaster without relying on tribal knowledge.
Question 2: Which metric measures the maximum tolerable length of time that a system can be offline?
- RPO
- RTO (Correct answer)
- MTTR
- MTBF
Correct answer: RTO
Recovery Time Objective (RTO) defines the maximum acceptable downtime before business operations are critically impacted.
Question 3: A warm standby site differs from a cold standby site primarily because it:
- Has no infrastructure at all
- Has pre-configured systems that require minimal setup to activate (Correct answer)
- Is always running in active-active mode
- Is located in the same building as the primary site
Correct answer: Has pre-configured systems that require minimal setup to activate
A warm standby site has pre-installed and partially configured infrastructure that can be activated quickly, unlike a cold site which has only basic facilities.
Question 4: What does 'failback' refer to in the context of disaster recovery?
- Moving operations from the primary to the recovery site
- Restoring operations back to the original primary site after recovery (Correct answer)
- Testing the backup systems for the first time
- Failing to meet the established RTO
Correct answer: Restoring operations back to the original primary site after recovery
Failback is the process of returning operations to the original primary site after the disaster has been resolved and the site is confirmed stable.
Question 5: In a disaster recovery scenario, 'parallel testing' means:
- Testing the DR plan while the primary system remains operational (Correct answer)
- Running backups in parallel with live systems
- Testing multiple vendors simultaneously
- Conducting tabletop exercises without using real systems
Correct answer: Testing the DR plan while the primary system remains operational
Parallel testing activates recovery systems alongside the primary system to validate DR capability without disrupting live production operations.
Question 6: Which backup strategy creates a copy of only the data that has changed since the last full backup?
- Incremental backup (Correct answer)
- Full backup
- Mirror backup
- Archive backup
Correct answer: Incremental backup
An incremental backup copies only data changed since the last backup of any type, minimizing storage and backup time but increasing restore complexity.
Question 7: What is the key advantage of using a geographically dispersed recovery site?
- Lower cost
- Reduced network latency
- Protection against regional disasters affecting both primary and recovery sites (Correct answer)
- Faster data replication
Correct answer: Protection against regional disasters affecting both primary and recovery sites
A geographically dispersed site ensures a regional event such as a hurricane or earthquake cannot simultaneously disable both the primary and recovery facilities.
