Cisco CCNP Security Core (SCOR) 350-701Security ConceptsHard
An organization relies heavily on a high-availability clustered database system for its critical business applications. A recent analysis revealed that while the database itself is resilient, the underlying network infrastructure has several single points of failure that could lead to a complete outage. To address this, the security team proposes implementing redundant network paths and devices. This initiative directly supports which aspect of the CIA triad?
- AConfidentiality
- BIntegrity
- CAvailability
- DNon-repudiation
Show answer & explanationAnswer & explanation
Correct answer: C. Availability
The problem states 'single points of failure that could lead to a complete outage' and the solution is 'redundant network paths and devices'. Both the problem and solution are directly concerned with ensuring continuous access and uptime of the system, which is the core principle of Availability.
Why the other options are wrong
- A. Confidentiality protects against unauthorized information disclosure.
- B. Integrity focuses on preventing unauthorized modification of data.
- D. Non-repudiation provides proof of action and origin.
High Availability (HA)
A system's ability to remain operational for an extended period, minimizing downtime through redundant components and failover mechanisms, directly supporting the Availability principle.
- Achieved through redundancy, clustering, load balancing, and disaster recovery.
- Crucial for mission-critical systems and services.
- Measured by uptime percentages (e.g., 'five nines' = 99.999% uptime).
Memory trick: Uptime, always on, always ready: that's Availability's core.
