What command would you use to resolve the IP address of srv.sophos.local and test connectivity simultaneously?

Using the ping command to resolve the IP address of srv.sophos.local while simultaneously testing connectivity is appropriate. When you execute this command, the first action it performs is to resolve the given hostname into its corresponding IP address through a DNS query. Following this resolution, the ping command sends ICMP echo request packets to the IP address to check if the host is reachable and measures the round-trip time for messages sent from your device to the target.

This dual functionality makes ping a practical tool for both resolving DNS names and verifying host availability in a single command, which is particularly useful in troubleshooting network connectivity issues.

The other commands listed serve different purposes: tracert is designed for tracing the route packets take to reach a destination, which helps determine where packets might be failing along the way. Nslookup is specifically for querying DNS records and resolving hostnames to IP addresses, but it does not check connectivity. Telnet is used to establish a connection to a specified port on a server but does not resolve the name unless it is first translated to an IP address through DNS.
