A local bank is designing its new infrastructure blueprint. Which of the following RAID types offers double parity? RAID 6 is the RAID level that provides double parity, allowing the system to tolerate the failure of two disks simultaneously without data loss. According to CompTIA Core 1 (220-1201) storage and RAID objectives, RAID 6 improves fault tolerance by storing two independent parity blocks across all disks in the array. RAID 0 provides no parity or redundancy and focuses only on performance through striping. RAID 1 uses mirroring, duplicating data across two drives but does not use parity. RAID 5 uses single parity, allowing recovery from only one failed drive. For environments such as a local bank, where data integrity and availability are critical, RAID 6 is commonly preferred due to its higher fault tolerance compared to RAID 5. Although RAID 6 has slightly lower write performance due to the additional parity calculation, the increased resilience makes it suitable for mission-critical systems. CompTIA highlights RAID 6 as a common enterprise solution when both redundancy and reliability are priorities.

The power supply for a user's gaming computer fails. The user buys a replacement online. The user connects the power supply to the motherboard, the graphics card, and the SSDs, but the computer fails to start and displays a critical error. Which of the following is the most likely cause? Modern motherboards require two separate power connections from the power supply: the 24-pin ATX connector for general motherboard power and a 4-pin or 8-pin CPU (EPS) connector dedicated to powering the processor. According to CompTIA Core 1 (220-1201) power supply installation and troubleshooting guidelines, failing to connect the CPU power connector commonly results in a system that does not boot and may display a critical or CPU-related error. In this scenario, the user connected power to the motherboard, graphics card, and storage devices, but the system fails to start. This strongly indicates that the CPU power connector was overlooked, which is a frequent mistake during PSU replacement. Without this connection, the processor cannot initialize, preventing POST. Insufficient wattage typically causes instability, shutdowns, or reboots under load rather than immediate failure with a critical error. RAM upgrades are unrelated to PSU replacement, and redundant power supplies are used in enterprise systems, not standard gaming PCs. CompTIA emphasizes verifying all required PSU connectors, especially the CPU power connector, as a critical troubleshooting step when a system will not power on after a PSU replacement.
