Given a scenario where a company wants to minimize downtime after a disaster, which DR metric should they focus on to determine the maximum tolerable period in which data might be lost?

• Recovery Time Objective (RTO)

• Recovery Point Objective (RPO)

• Mean Time Between Failures (MTBF)

• Service Level Agreement (SLA)

A business is considering three types of DR sites: cold, warm, and hot. If they need the fastest recovery time but are willing to pay higher costs, which type of DR site should they choose?

• Cold site

• Warm site

• Hot site

• Mobile site

You are tasked with improving the availability of a critical application. Which high-availability approach would best ensure continuous service if a single server fails?

• Single server deployment

• Active-passive clustering

• Manual failover

• Tape backup

A company wants to test its disaster recovery plan without disrupting normal operations. Which method should they use?

• Full interruption test

• Tabletop exercise

• Unannounced drill

• Data center shutdown

If a business sets an RTO of 4 hours for a critical system, what does this mean in practice?

• The system must be backed up every 4 hours

• The system must be restored within 4 hours after a disaster

• The system can lose up to 4 hours of data

• The system must be tested every 4 hours

Which of the following best describes the main difference between a warm site and a cold site in disaster recovery?

• Warm sites have no equipment, while cold sites have partial equipment

• Warm sites have up-to-date data and running systems, while cold sites do not

• Warm sites have some equipment and partial data, while cold sites have only basic infrastructure

• Warm sites are more expensive than hot sites

A company is considering implementing load balancing as part of its high-availability strategy. What is the primary benefit of this approach?

• Reduces the need for backups

• Distributes traffic to prevent overload on a single server

• Eliminates the need for disaster recovery planning

• Increases the cost of operations

During a DR test, the team discovers that some critical data was not restored as expected. What should be the next step?

• Ignore the issue and proceed

• Update the DR plan to address the gap and retest

• Cancel all future tests

• Remove the data from the backup schedule

Which scenario best illustrates the use of a hot site in disaster recovery?

• Employees are sent to a site with only desks and phones after a disaster

• Data and applications are immediately available at a fully equipped alternate location

• IT staff must install all hardware and software before operations can resume

• Backups are stored offsite but require manual retrieval

Why is it important to regularly test a disaster recovery plan?

• To increase the cost of IT operations

• To ensure the plan works as intended and identify weaknesses

• To reduce the number of employees needed

• To avoid creating documentation
