CompTIA A+ Core 1 (220-1001) — Question 99

A technician is troubleshooting network connectivity issues after a new wireless router was installed in an office. Users who connect to the new router are unable to access LAN resources. Which of the following is the MOST likely cause of the issue?

Answer options

• A. There are conflicting DHCP servers on the network
• B. There are conflicting ARP records
• C. There are conflicting gateways on the network
• D. There are conflicting IP protocols

Correct answer: A

Explanation

The correct answer is A because having multiple DHCP servers can lead to IP address conflicts, preventing users from accessing LAN resources. Options B, C, and D do not directly relate to the inability to access LAN resources in the context of a new router installation.
