A technician is troubleshooting a server in the finance office that hosts an internal accounting program.
The ticketing desk has received several calls from users reporting that access to the accounting program is degraded, and they are experiencing severe delays, sometimes timing out entirely.
The problem has been isolated to the server.
Which of the following tools should the technician use on the server to narrow down the issue?
A.
nslookup B.
iptables C.
pathping D.
netstat.
C.

The tool that a technician should use on the server to narrow down the issue is Pathping (option C).
Pathping is a network troubleshooting tool that combines the functionality of both the Ping and Traceroute commands. It provides information on the path that network traffic takes between the source and destination devices, including packet loss and latency data for each hop along the way.
In this case, since the issue has been isolated to the server, Pathping can be used to determine where along the network path the delays are occurring. By analyzing the results of the Pathping command, the technician can identify the specific hop or network device that is causing the problem.
Nslookup (option A) is a command-line tool used to query the Domain Name System (DNS) to obtain domain name or IP address mapping information. It is useful for troubleshooting DNS issues, but it would not help in diagnosing server performance issues.
Iptables (option B) is a Linux firewall tool that allows for the configuration of network traffic rules. While useful for securing a system against unauthorized access, it would not be helpful in diagnosing performance issues with a server.
Netstat (option D) is a command-line tool that displays information on active network connections and their associated protocol statistics. While it can be useful for monitoring network activity on a server, it would not be the most appropriate tool for diagnosing performance issues.
