CompTIA Security+ (SY0-601) — Question 64

A Chief Information Security Officer has defined resiliency requirements for a new data center architecture. The requirements are as follows:
* Critical fileshares will remain accessible during and after a natural disaster.
* Five percent of hard disks can fail at any given time without impacting the data.
* Systems will be forced to shut down gracefully when battery levels are below 20%.
Which of the following are required to BEST meet these objectives? (Choose three.)

Answer options

• A. Fiber switching
• B. IaC
• C. NAS
• D. RAID
• E. UPS
• F. Redundant power supplies
• G. Geographic dispersal
• H. Snapshots
• I. Load balancing

Correct answer: D, E, G

Explanation

RAID is crucial for data redundancy, allowing the data to remain intact even if some disks fail. A UPS ensures that systems can shut down safely before power runs out, thereby protecting data integrity. Geographic dispersal helps maintain access to critical fileshares during disasters by spreading resources across different locations. The other options do not directly contribute to meeting all specified resiliency requirements.
