CompTIA Network+ (N10-007) — Question 515

A user reports network resources can no longer be accessed. The PC reports a link but will only accept static IP addresses. The technician pings other devices on the subnet, but the PC displays the message Destination unreachable. Which of the following are MOST likely the causes of this issue? (Choose two.)

Answer options

• A. Damaged cables
• B. Crosstalk
• C. Bent pins
• D. TX/RX reverse
• E. VLAN mismatch
• F. Duplex mismatch

Correct answer: C, E

Explanation

The correct answers are C and E. Bent pins can prevent proper connection in the network interface, causing the device to be unreachable. A VLAN mismatch can also lead to connectivity issues as devices on different VLANs cannot communicate, while the other options do not directly cause the specific symptoms described.
