CompTIA Network+ (N10-008) — Question 670

A network administrator connects two unmanaged switches together with a straight-through Ethernet cable. The administrator reviews the connection and notices that the uplinks are not on. Which of the following options offers the best solution for the issue?

Answer options

• A. A rollover cable needs to be used.
• B. The switches needs to be rebooted after connecting.
• C. The ports need to be enabled.
• D. The ports need the IP address configured.
• E. A crossover cable needs to be used.

Correct answer: E

Explanation

Using a crossover cable is essential for connecting two similar devices like switches, as it allows for proper communication between them. A rollover cable is used for console connections, not for network traffic, and rebooting the switches will not resolve the issue if the cabling is incorrect. Enabling ports and configuring IP addresses are not relevant for the fundamental connectivity issue caused by using the wrong cable type.
