A technician is troubleshooting a computer issue for a user who works in a new annex of an office building. The user is reporting slow speeds and intermittent connectivity. The computer is connected via a Cat 6 cable to a distribution switch that is 492ft (150m) away. Which of the following should the technician implement to correct the issue?
Due to concerns around single points of failure, a company decided to add an additional WAN to the network. The company added a second MPLS vendor to the current MPLS WAN and deployed an additional WAN router at each site. Both MPLS providers use OSPF on the WAN network, and EIGRP is run internally. The first site to go live with the new WAN is successful, but when the second site is activated, significant network issues occur. Which of the following is the most likely cause for the WAN instability?

D.
Run a speed test on a device that can only achieve 100Mbps speeds.
Suggested answer: A

Explanation:

Importance of Proper Termination:

Cat 8 cabling requires precise termination practices to ensure signal integrity and reduce interference. One common requirement is to wrap the end connections in copper tape to maintain shielding and reduce electromagnetic interference (EMI).

Interference Troubleshooting:

Interference in high-frequency cables like Cat 8 can be caused by improper shielding or grounding. Checking the end connections for proper wrapping in copper tape is a crucial step.

Why Other Options are Less Likely:

Passthrough modular crimping plugs: Not specifically related to interference issues and are typically used for ease of cable assembly.

Connecting RX/TX wires to different pins: Would likely result in no connection or incorrect data transmission rather than interference.

Running a speed test on a device that can only achieve 100Mbps speeds: This would not diagnose interference and would not provide relevant information for Cat 8 cabling rated for higher speeds.

Corrective Actions:

Verify that all end connections are properly wrapped with copper tape before termination.

Ensure that the shielding is continuous and properly grounded throughout the installation.

Retest the cabling for interference after making corrections.
