Syslog is used to log system events and tasks performed by applications, providing a centralized record of activity.

Why Not A (Fileshare): Fileshares store files but are not designed for event logging.

Why Not C (Database): Databases can store logs but are not a logging mechanism themselves.

Why Not D (SAN): A SAN is a storage solution, not a logging tool.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, system monitoring and logging​.

CompTIA A+ explains that radio frequency (RF) connections use electromagnetic waves instead of copper or optical cabling. Satellite uses RF signals transmitted to and from orbiting satellites, while cellular networks (3G/4G/5G) use RF communications via cell towers.

Cable uses coaxial wired infrastructure, DSL uses telephone lines, Ethernet is twisted-pair copper, and fiber uses light instead of RF.

Satellite and cellular are the only technologies in the list that rely on wireless radio frequency transmission as their medium. The A+ networking domain emphasizes understanding the physical media of WAN technologies and distinguishing wired vs. wireless connectivity, making B and D the correct answers.

Comprehensive and Detailed Explanation

The wireless environment is crowded, and the office is using:

WEP encryption → obsolete, insecure, and supported only by outdated hardware

Default channel → likely causes interference in a busy area

CompTIA A+ emphasizes:

WEP should be replaced with WPA2 or WPA3

Older APs that only support WEP cannot simply be updated

Newer APs also allow dual-band / multiple channels to avoid interference

Therefore, the best solution is:

✔ Replace the access point with a modern WPA2/WPA3-capable AP that supports improved channel selection.

Why the other options are incorrect

B. Disabling SSID broadcast – Does nothing for performance or security.

C. MAC filtering – Ineffective for performance and easily bypassed.

D. Updating firmware – Cannot upgrade WEP hardware to WPA2/3 if hardware limitations exist.

Final Answer: A

Ultra HD (UHD), also referred to as4K UHD, has a resolution of3840x2160. It ' s four times the resolution of standard 1080p (Full HD), offering more screen real estate and sharper images.

Option A (1920x1080):Full HD (FHD), not UHD.

Option B (2048x1080):DCI 2K used in cinema, not common for Ultra HD.

Option D (7680x4320):Known as 8K UHD, not standard Ultra HD.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.7: Compare and contrast display technologies and their features.
