CompTIA Network+ (N10-008) — Question 325

On a network with redundant switches, a network administrator replaced one of the switches but was unable to get a connection with another switch. Which of the following should the administrator check after successfully testing the cable that was wired for TIA/EIA-568A on both ends?

Answer options

• A. If MDIX is enabled on the new switch
• B. If PoE is enabled
• C. If a plenum cable is being used
• D. If STP is disabled on the switches

Correct answer: A

Explanation

The correct answer is A because MDIX (Media Dependent Interface Crossover) settings determine whether a switch port can automatically detect and configure for a straight-through or crossover connection, which is crucial for connecting switches. The other options, while relevant to network configuration, do not directly address the connection issue between the switches.
