ISC2 CC Security Principles Practice Question
An organization implements a redundant server infrastructure to ensure that services remain operational even if one server fails. This is an example of protecting which principle?
⚠ Common exam trap
Watch out — candidates often confuse availability with integrity or confidentiality, as candidates might think redundancy also protects data integrity, but it primarily ensures uptime.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Availability
Redundant server infrastructure ensures that services remain operational even if one server fails, which directly supports the principle of availability. Availability ensures that systems and data are accessible to authorized users when needed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Availability
Why this is correct
Redundant servers let a service continue functioning when one fails, directly satisfying the requirement that services remain operational despite failure. Availability is the principle concerned with uptime and continuous access, so eliminating single points of failure protects it rather than integrity, confidentiality or non-repudiation.
- ✗
Integrity
Why it's wrong here
Integrity concerns data remaining accurate and unaltered, which redundancy does not address; it protects availability instead. Integrity is tempting because it is a core security principle, but it would be the answer if the scenario described hashing or checksums detecting unauthorised modification of stored data.
- ✗
Accountability
Why it's wrong here
Accountability concerns tracing actions to a responsible identity through logging and auditing, which redundant servers do not deliver. It tempts because accountability is a recognised security principle, but it would be the answer if the scenario described audit trails or non-repudiation of user activity.
- ✗
Confidentiality
Why it's wrong here
Confidentiality concerns restricting data access to authorised parties, typically through encryption and access controls, which redundancy does not provide. It is tempting because confidentiality is a headline security principle, but it would be correct if the scenario involved protecting data from unauthorised disclosure.
