Answer - D - David should use the PING utility to verify whether the host on his network can connect to the internet.

Key Takeaway: Ping utility is used to test whether a particular host is reachable across an IP network. It can also be used to measure the round-trip time for packets sent from the local host to a destination computer. It operates by sending an ICMP echo request packet to the target host and waiting for an ICMP response. The use of the ping utility is usually described as pinging a host computer.
