CompTIA Security+ (SY0-601) — Question 293

An organization has been experiencing outages during holiday sales and needs to ensure availability of its point-of-sale systems. The IT administrator has been asked to improve both server-data fault tolerance and site availability under high consumer load. Which of the following are the best options to accomplish this objective? (Choose two.)

Answer options

• A. Load balancing
• B. Incremental backups
• C. UPS
• D. RAID
• E. Dual power supply
• F. VLAN

Correct answer: A, D

Explanation

Load balancing helps distribute the traffic evenly across multiple servers, preventing any single server from being overwhelmed during peak times, thereby ensuring availability. RAID (Redundant Array of Independent Disks) provides fault tolerance by storing data across multiple disks, which protects against data loss and improves performance, making these two options the best for achieving the organization's goals.
