Selected Answer: A
A. Check to see if the end connections were wrapped in copper tape before terminating. Explanation: Cat 8 cables are designed for high-speed, high-frequency environments, and proper shielding is crucial to minimize interference. The shielding needs to be continuous, and ensuring that the end connections are wrapped in copper tape before termination helps maintain this shielding. If this step is overlooked, it can lead to higher interference and degraded performance.

Selected Answer: A
The correct answer is: A. Check to see if the end connections were wrapped in copper tape before terminating. Explanation: Cat 8 cables are designed for high-speed data transmission in data centers and have stringent requirements to minimize interference and maintain shielding integrity. One critical aspect of Cat 8 installation is ensuring that the shielding (often foil or braided) remains continuous and properly grounded, especially at termination points. Wrapping the end connections in copper tape before termination ensures proper contact with the keystone jack, maintaining the shield's effectiveness and minimizing interference.
