Troubleshooting VPN Connectivity Issues

A network technician is assisting a user who is experiencing connectivity problems with the VPN.

The technician has confirmed the VPN is functioning and other users at the site cannot access the Internet.

Which of the following commands would MOST likely be used to further troubleshoot?

A.

tracert

B.

netstat

C.

arp

D.

dig.

A.

The most likely command to be used to further troubleshoot VPN connectivity issues in this scenario is "tracert" (A).

Tracert (short for "trace route") is a command-line tool used to trace the path of an IP packet from a source device to a destination device. By using tracert, network technicians can identify where packets are being dropped or experiencing high latency in a network. In this case, the technician can use tracert to trace the path of packets between the user's device and the VPN endpoint, which can help identify where the connectivity issue is occurring.

Netstat (B) is a command-line tool used to display network statistics, including active connections, listening ports, and routing tables. While netstat can be useful in some troubleshooting scenarios, it is unlikely to help in this case, as the problem is specific to VPN connectivity and not general network connectivity.

ARP (C) is a command-line tool used to display and modify the Address Resolution Protocol (ARP) cache, which is used to map IP addresses to MAC addresses on a local network. ARP is unlikely to be useful in this scenario, as the problem is related to VPN connectivity and not local network connectivity.

Dig (D) is a command-line tool used to perform DNS queries, such as looking up the IP address associated with a domain name. While DNS issues can sometimes cause connectivity problems, dig is unlikely to be useful in this scenario, as the problem is related to VPN connectivity and not DNS resolution.
