CompTIA Updated 220-1201 Exam Questions and Answers by euan

A. Run the maintenance application:

Most modern printers include a built-in maintenance application that can calibrate the print heads and correct alignment issues. Running this tool is the first step to address misalignment.

Incorrect Options:

B. Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not alignment problems.

C. Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is not the first step for fixing alignment.

D. Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.

Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly installed printer.

Degraded performance that occurs only during business hours strongly suggests network congestion caused by simultaneous data and voice traffic. According to CompTIA Core 1 (220-1201) networking objectives, combining voice (VoIP) and data traffic on the same network without proper segmentation can lead to latency, jitter, and packet loss, especially during peak usage periods.

Implementing VLANs (Virtual Local Area Networks) allows administrators to logically separate voice and data traffic, enabling better traffic management and prioritization. VLANs also support Quality of Service (QoS) policies that ensure time-sensitive voice traffic is prioritized over standard data traffic, improving call quality and overall performance.

Replacing switches with higher-capacity models is costly and unnecessary if proper traffic segmentation has not yet been implemented. Adding RAM to PCs or VoIP lines does not address network-level congestion. Firmware updates may improve stability but will not resolve sustained performance degradation caused by traffic contention.

CompTIA highlights VLAN implementation as a best practice for environments that use IP phones, especially when performance issues occur during high utilization periods.

Comprehensive and Detailed Explanation From Exact Extract:

MDM (Mobile Device Management) enforces security policies, such as encryption, remote wipe, and access control. It could have remotely wiped the device or locked it down to prevent data theft.

802.11ac is a Wi-Fi standard that primarily operates in the 5GHz band and is known for higher throughput and improved performance compared with older 2.4GHz-focused standards. In CompTIA A+ Core 1 networking objectives, you are expected to recognize which IEEE 802.11 standards map to which frequency bands and the typical trade-offs. The 5GHz band generally provides more available non-overlapping channels and less interference from common household devices (like microwaves and many Bluetooth peripherals), which can improve real-world performance. While 5GHz typically has shorter range and weaker wall penetration than 2.4GHz, it often delivers better speeds in the same-room or nearby-room scenarios, which aligns with how 802.11ac is commonly deployed.

Bluetooth primarily uses the 2.4GHz ISM band and is designed for short-range personal area networking rather than high-speed WLAN connections. NFC operates at 13.56MHz for very short-range tap-based communications. RFID can operate at several bands (low frequency, high frequency, ultra-high frequency) depending on the use case, but it is not a Wi-Fi networking standard and does not “primarily” operate at 5GHz. Therefore, the correct answer is 802.11ac.
