CompTIA Updated 220-1201 Exam Questions and Answers by reece

The correct answer is B. Near-field communication (NFC).

According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:

NFC is commonly used for secure access control. Many organizations implement NFC-enabled ID badges or mobile devices to unlock doors, gates, or secure areas.

The mobile device communicates over a very short range (a few centimeters) with a reader to authenticate the user.

Why the other options are incorrect:

A. Hotspot: Provides internet access, not physical building access.

C. Infrared scanner: While used in some legacy devices, it is not commonly implemented for secure mobile access.

D. Geolocation: Can provide location awareness but does not grant direct access to secure physical spaces.

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

application server.

Click on Server 1 and Server 2 and review

the information presented in each chart to

determine which drives need to be replaced.

Select the appropriate replacement drive

that should be used, for the least

performance degradation to the server.

The correct answer is B. Change the fuser temperature.

According to CompTIA A+ Core 1 220-1201 objectives under Printers:

A laser printer fuses toner onto paper using heat and pressure. Thicker paper often requires a higher fuser temperature to properly adhere the toner.

If the output smudges on thick paper but prints fine on standard paper, adjusting the fuser temperature is the first step before performing more invasive maintenance or replacing parts.

Why the other options are incorrect:

A. Install a maintenance kit: Typically includes rollers, belts, and other parts; this is not the first action if the issue is temperature-related.

C. Clean the transfer roller: Cleaning may improve print quality, but smudging on thick paper usually relates to insufficient fusing heat.

D. Install an OEM toner cartridge: The issue is unlikely to be caused by non-OEM toner if standard paper prints correctly.
