CISSP Question #547: Real Exam Question with Answer & Explanation

Question

Continuity of operations is BEST supported by which of the following?

Options

• AConfidentiality, availability, and reliability
• BConnectivity, reliability, and redundancy
• CConnectivity, reliability, and recovery
• DConfidentiality, integrity, and availability

Explanation

Continuity of operations focuses on maintaining business functions during and after disruptions, which requires specific operational pillars rather than security-focused principles.

Common mistakes.

• A. Confidentiality and integrity are information security properties (part of the CIA triad) that protect data, but they do not directly address the operational continuity requirements of keeping systems connected and recoverable during disruptions.
• B. While connectivity and reliability are correct pillars, redundancy is a technique used to achieve continuity rather than a core operational principle of continuity itself, and recovery is more directly aligned with continuity planning than redundancy alone.
• D. Confidentiality, integrity, and availability (CIA triad) are the foundational principles of information security, not continuity of operations - although availability overlaps, this triad is specifically associated with data security rather than operational continuity planning.
