Which practice involves training multiple employees to perform the same critical job to reduce risk?

• A. Mandatory Vacation
• B. Least Privilege
• C. Job Rotation
• D. Interoperability Agreements

Answer: (C)

Training multiple people to perform the same critical job is known as job rotation. This practice builds redundancy by cross-training staff so several individuals understand how a key task is done. The main benefit is that no single person is the sole keeper of that process: if someone is unavailable, another trained colleague can take over, helping maintain continuity and resilience. It also broadens awareness of security controls and procedures across the team, making it easier to spot mistakes or irregularities and reducing the risk associated with knowledge silos.

Mandatory vacation forces a review of tasks when someone is away, which can help reveal fraudulent activity, but it doesn’t by itself establish cross-trained coverage. Least privilege focuses on limiting access rights to only what is needed, not on training multiple people for a given job. Interoperability agreements concern how different systems or organizations work together, not internal cross-training.
