220-1201 CompTIA A+ Core 1 Exam (2026) Free Practice Exam Questions (2026 Updated)

Because the smudges are not in the original document, CompTIA A+ troubleshooting logic indicates the problem is occurring inside the print process, not in the application or file. For laser printers, smudging commonly points to an issue with the imaging components—especially the drum/photoconductor unit (and sometimes the fuser). A+ Core 1 (220-1201) printer troubleshooting emphasizes starting with the most likely, easiest-to-verify causes before replacing parts. Inspecting the drum is a diagnostic step that can reveal visible defects such as scratches, toner buildup, contamination, or worn surfaces that cause toner to transfer incorrectly, leading to streaks or smears on output.

Replacing the toner (D) is a corrective action and may be unnecessary if the drum is damaged. Changing paper type (A) can help with some issues (like poor fusing or humidity-related problems), but it’s less directly tied to consistent smudges caused by the imaging process. Firmware updates (C) are rarely the first step for print-quality defects; they’re more relevant to compatibility, bugs, or feature issues—not physical smearing. Therefore, inspecting the printer drum first best matches A+ methodology and common laser printer failure points.

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.

For the highest possible stability, the best power-supply choice is a redundant power supply. In CompTIA A+ Core 1 (220-1201) hardware concepts, redundant PSUs are used in systems where uptime and reliability are critical. A redundant PSU configuration typically includes two power supply units operating together (often in a hot-swappable bay). If one PSU fails, the other continues supplying power, allowing the workstation to remain operational and preventing unexpected shutdowns that could interrupt CAD work or corrupt data. This directly matches the requirement for maximum stability.

A UPS improves resilience to power loss and brownouts by providing battery backup and line conditioning, but it is not a power supply type and doesn’t protect against the PSU itself failing. A surge protector helps guard against voltage spikes, but it also does not ensure system operation if the PSU fails. A modular PSU mainly improves cable management and airflow by allowing detachable cables; it can be convenient and neat, but it does not inherently increase stability compared with redundancy. Therefore, the most stability-focused PSU option is Redundant.
