CompTIA Exam N10-008 Topic 1 Question 43 Discussion

Actual exam question for CompTIA's N10-008 exam

Question #: 43
Topic #: 1

A user reports having intermittent connectivity issues to the company network. The network configuration for the user reveals the following:

IP address: 192.168.1.10

Subnet mask: 255.255.255.0

Default gateway: 192.168.1.254

The network switch shows the following ARP table:

Which of the following is the most likely cause of the user's connection issues?

AA port with incorrect VLAN assigned

BA switch with spanning tree conflict

CAnother PC with manually configured IP

DA router with overlapping route tables

Show Suggested Answer

Suggested Answer: C

This is the most likely cause of the user's connection issues, because the ARP table of the switch shows that there are two devices with the same IP address of 192.168.1.10, but different MAC addresses. This indicates that there is an IP address conflict on the network, where two devices are trying to use the same IP address. This can cause intermittent connectivity issues, as the switch may not be able to forward packets to the correct destination .

Haha, I bet the user is frustrated. Troubleshooting network issues can be like a game of 'Where's Waldo?' for some people.

Yeah, I'd go with option C as well. It's the only answer that really matches the information provided in the question. The other options don't seem to fit the scenario.

I agree. The ARP table shows a conflicting MAC address for the 192.168.1.10 IP address, which suggests another device is using that IP. That's probably causing the intermittent connectivity issues for the user.

Hmm, this question seems pretty straightforward. Based on the network configuration and the ARP table, I think the most likely cause of the connectivity issues is another PC with a manually configured IP address.
