Answer 1

The correct answer is Option 3) nslookup.

Key Points

nslookup stands for "Name Server Lookup".
It is a network administration command-line tool used to query DNS to obtain domain name or IP address mapping.
When used, it reveals the DNS server the system is using to resolve queries.
For example:
```
nslookup www.google.com
```
This will display the DNS server being queried and the IP address of the domain.

Additional Information

Option 1 – tracer: Incorrect. Likely a typo for tracert (in Windows) or traceroute (in Unix), which shows the path taken by packets to reach a host, not DNS configuration.
Option 2 – ping: Sends ICMP echo requests to test network connectivity, does not reveal DNS server info.
Option 4 – whois: Queries domain registration information from registrars, not your system's DNS settings.

Conclusion: nslookup is the correct command to identify the DNS server your computer is configured to use.
