Fiber optic connections provide the highest data transfer rates and symmetrical upload and download speeds. This makes fiber the ideal choice for applications requiring high-speed connectivity, such as video conferencing, large file transfers, and cloud-based workflows.

AnMX (Mail Exchange)record defineswhich mail servers are responsible for receiving emailfor a domain. If you want to change or redirect email traffic, theMX recordmust be updated with the correct server information.

Option B (TXT):Stores text-based info used for SPF, DKIM, etc.

Option C (SPF):Part of email authentication stored in a TXT record; doesn’t redirect traffic.

Option D (CNAME):Alias for another domain name not used for email routing.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.4: Compare and contrast common networking hardware.

===========

Unmanaged switches require no configuration they simply need to be plugged in and start working immediately, making them ideal for simple network setups.

Managed switches provide advanced features such as VLANs, SNMP monitoring, port security, and traffic management, but require configuration.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 – Compare and contrast common networking hardware:

“Unmanaged switches operate out of the box with no configuration and are designed for simple connectivity. Managed switches allow for configuration, monitoring, and management of network traffic and security.”

CompTIA A+ explains that Wi-Fi issues at the edges of a building are typically caused by weak signal coverage, not client configuration. The recommended solution is to add additional wireless access points (APs) or mesh extenders to expand coverage and eliminate dead zones.

Enabling 5GHz would worsen the problem because 5GHz has shorter range and penetrates walls less effectively than 2.4GHz. Flushing DNS affects name resolution, not wireless signal strength. Upgrading the NIC to Wi-Fi 6 improves maximum throughput but still depends on sufficient signal, which the user does not have.

Additional APs ensure strong signal-to-noise ratio, consistent throughput, and stable roaming all solutions emphasized in the A+ wireless troubleshooting section. Therefore, option D is the correct and CompTIA-aligned fix.
