Quick Answer
The answer is backup procedures and schedules, along with recovery time objectives (RTOs) and recovery point objectives (RPOs), as these three form the core operational framework of any disaster recovery plan. Backup procedures and schedules ensure data is consistently copied and available for restoration, while RTOs define the maximum acceptable downtime for critical systems, directly shaping the recovery strategy and resource allocation. RPOs, in turn, set the maximum tolerable data loss measured in time, dictating backup frequency. On the ISC2 Certified in Cybersecurity CC exam, this topic tests your understanding of how these elements work together to meet business continuity requirements—a common trap is confusing RTOs with RPOs or overlooking that schedules are just as essential as the backups themselves. Remember the mnemonic “BRR” for Backup, RTO, RPO: these three essentials ensure you can recover both your systems and your data within the business’s tolerance for interruption.
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.
Which THREE are essential elements of a disaster recovery plan? (Select THREE.)
Recovery time objectives (RTOs)
Define target restoration times.
Communication plan for employees
Why wrong: Part of crisis management plan.
Business impact analysis results
Why wrong: BIA is part of BCP, not DRP.
Alternate processing site details
Essential if primary site is unavailable.
Backup procedures and schedules
Necessary for data restoration.
Answer choices

Correct answer & explanation
Recovery time objectives (RTOs)
Recovery time objectives (RTOs) define the maximum acceptable downtime for a system or application after a disaster. They are essential because they directly drive the design of the recovery strategy, including resource allocation and technology choices, ensuring that critical services are restored within the business's tolerance for interruption.
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 a disaster recovery plan (which focuses on IT systems and data recovery) and a business continuity plan (which includes broader organizational elements like employee communication and crisis management), causing candidates to mistakenly select the communication plan as a DRP essential.
Detailed technical explanation
RTOs are measured in time units (e.g., minutes, hours) and are tied to specific recovery tiers (e.g., hot, warm, cold sites). For example, a financial trading system might have an RTO of 15 minutes, requiring synchronous replication and automated failover, whereas a less critical HR system might have an RTO of 24 hours, allowing for tape restore. The alternate processing site details (Option D) must match the RTO; a cold site cannot meet a 15-minute RTO. Backup procedures and schedules (Option E) must align with the recovery point objective (RPO), which is often paired with RTO in the DRP.
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.
