Which command can be used to verify that the FQDNs of both domains can be resolved?

Using the nslookup command is an effective way to verify that Fully Qualified Domain Names (FQDNs) can be resolved. This command queries the Domain Name System (DNS) to retrieve information about a domain, including its IP address, which is crucial for confirming whether the FQDN resolves correctly.

When you run nslookup followed by a domain name, it sends a request to the DNS server to look up the specified FQDN and returns the corresponding IP address if it exists. This process helps to ensure that the domain is correctly set up in DNS, allowing for connectivity and proper functioning of services associated with that domain.

Other commands, while useful for different purposes, do not serve the same function. For instance, ping tests network connectivity by sending packets to a designated IP address or hostname but does not specifically query DNS records. Tracert is used to trace the route packets take to reach a destination and provides diagnostic information about the path but does not directly confirm domain resolution. The get-hostname command retrieves the hostname of the local machine without checking external domain resolution, therefore, it is not applicable for verifying FQDNs beyond the local environment.
