Certified Network Defender (CND) — Question 157

Which of the following steps will NOT make a server fault tolerant? Each correct answer represents a complete solution. (Choose two.)

Answer options

• A. Adding a second power supply unit
• B. Performing regular backup of the server
• C. Adding one more same sized disk as mirror on the server
• D. Implementing cluster servers' facility
• E. Encrypting confidential data stored on the server

Correct answer: B, E

Explanation

Options B and E do not enhance fault tolerance. Regular backups (B) are essential for data recovery but do not prevent server failures. Similarly, encrypting data (E) protects it from unauthorized access rather than improving the server's ability to remain operational during a fault.
