Selected Answer: B
A. is incorrect. The flush process must be performed in the client, not in the server. C. is incorrect. ARP entries are mappings between layer 2 and 3 addresses, not hostnames or FQDNs D. is incorrect. "utils network name-service hosts cache validate" does not exist. B. is correct. It is the best answer.
