CompTIA Network+ (N10-009) — Question 398
A network administrator is troubleshooting a connectivity issue between two devices on two different subnets. The administrator verifies that both devices can successfully ping other devices on the same subnet. Which of the following is the most likely cause of the connectivity issue?
Answer options
- A. Incorrect default gateway
- B. Faulty Ethernet cable
- C. Wrong duplex settings
- D. VLAN mismatch
Correct answer: A
Explanation
The most likely reason for the connectivity issue is an incorrect default gateway, as this would prevent communication between different subnets. The other options, such as a faulty Ethernet cable, wrong duplex settings, or VLAN mismatch, would typically affect connectivity within the same subnet rather than between different subnets.
