Why each option
To diagnose DNS functionality on a Windows system, the nslookup command is specifically used to query DNS servers for information about domain names and IP addresses.
nbtstat is used to display NetBIOS over TCP/IP protocol statistics and the NetBIOS name cache, not DNS resolution.
traceroute (or tracert on Windows) is used to display the route and measure transit delays of packets across an IP network, which is for network path testing, not DNS functionality.
The nslookup command allows administrators to query DNS servers directly, resolving hostnames to IP addresses or vice versa, thereby confirming if DNS resolution is functioning correctly. It provides detailed information about DNS records and the DNS server being used.
ipconfig displays current TCP/IP network configuration values and can refresh DHCP and DNS settings, but it does not directly test DNS resolution by performing queries.
