220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

Mobile Application Management (MAM) enforces policies restricting access to apps and services based on location, ensuring security at external sites.

Why Not A (MOW): "Mobile Only Workplace" (MOW) is not a recognized term in this context.

Why Not B (MAN): Metropolitan Area Network (MAN) is unrelated to mobile device policies.

Why Not C (MFA): Multi-Factor Authentication secures user accounts but does not enforce app restrictions.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, mobile device security policies​.

If a desktop PC shuts down suddenly and there is a burning smell coming from the area where it is connected to the wall socket, the first step should be to check that the power cable is not damaged. A damaged power cable can cause electrical shorts or overheating, leading to sudden shutdowns and a burning smell. Inspecting the power cable for fraying, cuts, or other damage can help identify if it is the source of the problem.

Basic electrical safety and troubleshooting principles, emphasizing the importance of checking power connections and cables when faced with symptoms of electrical issues.

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.
