What is the main goal of a Disaster Recovery (DR) plan?
To restore systems and data quickly after a disruption
To prevent disasters from happening
To eliminate the need for backups
To increase the cost of IT operations
Which of the following best describes a Recovery Point Objective (RPO)?
How long a disaster lasts
The average time to repair a system
How much data loss is acceptable
The time between system failures
A company has an RTO of 2 hours. What does this mean?
They must back up data every 2 hours
Systems must be restored within 2 hours of failure
It takes 2 hours to fix any problem
The system fails every 2 hours
Which disaster recovery site is most expensive and offers the fastest recovery time?
Hot Site
Cold Site
Warm Site
Shared Site
What is the primary difference between active-passive and active-active high availability setups?
Active-passive uses more bandwidth
Active-active setups are cheaper to implement
Active-active systems both operate simultaneously
Active-passive setups have no backup system
Which of the following is a characteristic of a cold site?
Real-time data syncing
Fully equipped with hardware
Requires setup after a disaster
Provides instant recovery
What is the purpose of a tabletop exercise in disaster recovery testing?
To simulate a real disaster using live systems
To identify hardware vulnerabilities
To discuss the response plan without affecting systems
To recover data from old backups
What metric shows the average time it takes to fix a system after a failure?
RTO
MTTR
MTBF
RPO
Which testing method validates the disaster recovery plan using actual systems?
Tabletop Exercise
Risk Assessment
Penetration Testing
Validation Test
If a system has a high Mean Time Between Failures (MTBF), what does that indicate?
It needs frequent maintenance
It fails often
It is very reliable
It is expensive to maintain
