Quick Answer
The answer is Recovery Time Objective (RTO). This metric defines the maximum acceptable time to restore systems and data after a disaster, directly matching the organization’s requirement to recover within two hours of a system failure. In a backup strategy, the RTO drives decisions on failover mechanisms, replication speed, and restoration procedures to meet that specific downtime limit. On the ISC2 Certified in Cybersecurity CC exam, this concept tests your understanding of disaster recovery planning, often appearing in scenario-based questions where you must distinguish RTO from Recovery Point Objective (RPO)—a common trap is confusing the two, but remember: RTO is about time to restore, while RPO is about data loss tolerance. A helpful memory tip is to think of the “T” in RTO as standing for “Time to get back online.”
This CC practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization wants to ensure that its backup strategy can recover data within 2 hours after a system failure. Which metric should be defined in the disaster recovery plan?
Mean Time Between Failures (MTBF)
Why wrong: A reliability metric, not recovery time.
Recovery Point Objective (RPO)
Why wrong: Specifies maximum data loss, not time to recovery.
Service Level Agreement (SLA)
Why wrong: A contract between provider and customer, not a recovery metric.
Recovery Time Objective (RTO)
Specifies the maximum time to restore services after a disaster.

Correct answer & explanation
Recovery Time Objective (RTO)
The Recovery Time Objective (RTO) defines the maximum acceptable time to restore systems and data after a disaster, directly addressing the 2-hour recovery requirement. In the context of backup strategy, RTO drives decisions on failover mechanisms, replication speed, and restoration procedures to meet the specified downtime limit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Mean Time Between Failures (MTBF)
Why it's wrong here
A reliability metric, not recovery time.
Recovery Point Objective (RPO)
Why it's wrong here
Specifies maximum data loss, not time to recovery.
Service Level Agreement (SLA)
Why it's wrong here
A contract between provider and customer, not a recovery metric.
Recovery Time Objective (RTO)
Why this is correct
Specifies the maximum time to restore services after a disaster.

Common exam traps
ISC2 often tests the distinction between RTO and RPO, where candidates mistakenly choose RPO because they confuse 'recovery of data' with 'time to recover' rather than 'point in time to which data is recovered'.
Detailed technical explanation
RTO is typically measured from the moment of failure declaration to full service restoration, including steps like system boot, data restoration from backup media or replicas, and validation checks. In real-world scenarios, a 2-hour RTO might require hot standby systems or automated failover scripts, as tape-based restores often exceed this window due to sequential read speeds and manual intervention. Cisco's disaster recovery frameworks often align RTO with backup frequency and replication technology (e.g., synchronous vs. asynchronous replication) to ensure the target is achievable.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
