The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.

Recommended Replacement Drive:

To minimize performance degradation, the replacement drive should be:

SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).

Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.

In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.

A user reports poor performance on the

Comprehensive and Detailed In-Depth Explanation:

USB-C is a versatile connector capable of transmitting data, video, audio, and power. With standards like DisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more — all through one cable.

Option B (HDMI): Supports video and audio but not general data transfer.

Option C (DisplayPort): Similar to HDMI — supports video/audio but not general file transfer.

Option D (VGA): Legacy analog video only — no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

Comprehensive and Detailed In-Depth Explanation:

A VLAN (Virtual LAN) is used to logically segment a network without requiring physical separation. It enables grouping devices based on function or department regardless of their physical location.

Option A (DHCP): Assigns IP addresses dynamically but doesn’t create network segments.

Option C (DNS): Resolves domain names to IP addresses, not used for network segmentation.

Option D (VPN): Provides secure remote access but does not relate to logical segmentation within a local network.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.3: Explain common logical networking concepts.

When upgrading a laptop's storage from an HDD to an SSD, especially in laptops with only a single bay for a hard drive, the most critical characteristic to consider is the form factor. The form factor must match the physical dimensions and interface of the original HDD to ensure that the SSD can fit into the bay and connect properly. Storage size (B) is important for capacity reasons, transfer speed (D) affects performance, and partition type (A) is a software configuration aspect, but the form factor (C) is crucial for the physical compatibility of the SSD with the laptop.

When a user consistently receives an error requesting A4 paper for print jobs, and no other users are experiencing similar issues, it indicates a possible misconfiguration in the user's printer settings. By setting the printer defaults in the Control Panel to use letter-sized paper, which is more common in some regions, this ensures that the user's print jobs are aligned with the available paper size in the office printer. This approach addresses the root cause of the issue by ensuring that the default settings match the paper size used in the office, eliminating the need for the user to adjust settings for each print job.

NFC stands for near-field communication, which is a wireless technology that allows two devices to exchange data when they are in close proximity (usually within a few centimeters). NFC is commonly used by mobile devices to process payments at kiosks, such as Apple Pay or Google Pay. Wi-Fi 6 is a wireless standard that provides faster speed and lower latency than previous versions of Wi-Fi. Bluetooth is a wireless technology that allows devices to communicate over short distances (usually within 10 meters). RFID stands for radio-frequency identification, which is a wireless technology that uses radio waves to identify and track objects that have RFID tags attached to them

Clicking and grinding noises indicate mechanical drive failure.

SMART data provides insights into the health and status of drives, helping identify failing components in the RAID array.

Why Not A (Run a magnet): This would damage drives.

Why Not B (Check if one drive is not level): Physical leveling is irrelevant.

Why Not D (Check OS logs): OS logs may provide limited information for RAID arrays.

Why Not E (Update RAID controller firmware): While important, it does not diagnose drive failure.

A failing power supply can cause random system crashes and degraded performance as it struggles to maintain a consistent voltage, especially as the system demands increase over time. The CMOS battery only affects system time and settings, while the video card typically causes display issues rather than system-wide crashes. System memory issues often result in specific errors or performance issues rather than gradual slowdowns. CompTIA A+ Core 1 objectives highlight troubleshooting power supply issues as part of hardware and system maintenance.
