CompTIA Network+ (N10-009) — Question 168

Following a fire in a data center, the cabling was replaced. Soon after an administrator notices network issues. Which of the following are the most likely causes of the network issues? (Choose two.)

Answer options

• A. The switches are not the correct voltage
• B. The HVAC system was not verified as fully functional after the fire
• C. The VLAN database was not deleted before the equipment was brought back online
• D. The RJ45 cables were replaced with unshielded cables
• E. The wrong transceiver type was used for the new termination
• F. The new RJ45 cables are a higher category than the old ones

Correct answer: D, E

Explanation

The issues are likely caused by the replacement of RJ45 cables with unshielded types (D), which could lead to interference and degraded signal quality. Additionally, using the wrong transceiver type for the new termination (E) can result in compatibility issues, further contributing to network problems. The other options do not directly relate to the cabling and termination changes that were made.
