Quick Answer
The answer is Recovery Time Objective (RTO), Recovery Point Objective (RPO), and Business Impact Analysis (BIA). These three components are commonly defined in a disaster recovery plan because they form the foundation for setting acceptable downtime and data loss limits. RTO specifies the maximum time allowed to restore systems after a disaster, while RPO defines the maximum acceptable data loss measured in time, such as one hour, which directly drives backup frequency and replication technology choices like synchronous versus asynchronous replication. The BIA identifies critical business functions and quantifies the impact of disruptions, ensuring recovery priorities align with organizational needs. On the ISC2 Certified in Cybersecurity CC exam, this tests your understanding of core disaster recovery metrics and their roles; a common trap is confusing RTO with RPO—remember that RTO is about time to recover, while RPO is about data loss tolerance. A helpful memory tip: “RTO = Time to Restore, RPO = Point of Data Loss.”
This CC practice question tests your understanding of business continuity, dr & incident response. 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.
Which THREE are commonly defined in a disaster recovery plan? (Select exactly 3.)
Recovery point objective
RPO defines the maximum acceptable data loss.
Business impact analysis
BIA identifies critical processes and recovery priorities, foundational to DR.
Recovery time objective
RTO defines the maximum acceptable downtime.
Cost-benefit analysis
Why wrong: CBA is used in decision-making but is not typically in the DR plan itself.
Annual loss expectancy
Why wrong: ALE is a risk assessment metric, not a DR plan component.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Recovery point objective
Recovery point objective (RPO) is a core metric defined in a disaster recovery plan because it specifies the maximum acceptable amount of data loss measured in time. For example, an RPO of 1 hour means backups must be taken at least every hour to ensure no more than 60 minutes of data is lost. This directly drives backup frequency and replication technology choices, such as synchronous vs. asynchronous replication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
ISC2 often tests the distinction between the DR plan components (RPO, RTO, BIA) and risk management calculations (ALE, cost-benefit analysis), trapping candidates who confuse the outputs of a BIA with separate financial analysis tools.
Detailed technical explanation
RPO and RTO are often confused but serve distinct roles: RPO dictates how frequently data must be backed up (e.g., every 15 minutes via continuous data protection), while RTO dictates how quickly systems must be restored (e.g., 4 hours for critical servers). Business impact analysis (BIA) is the prerequisite process that identifies critical functions and their dependencies, producing the RPO and RTO values that are then formally documented in the DR plan. In practice, a BIA might reveal that a financial transaction system requires an RPO of 0 (zero data loss), mandating synchronous replication across data centers.
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.
