IP Services

When a router is using the default DNS lookup configuration, what happens if a URL is entered at the CLI?

  • A It continuously attempts to resolve the URL until the command is cancelled.
  • B It initiates a ping request to the URL.
  • C It prompts the user to specify the desired IP address.
  • D It attempts to query a DNS server on the network.
Explanation

With the default Cisco IOS setting, DNS hostname lookup is enabled. If text entered at the CLI is not recognized as a valid command, the router treats it as a hostname and attempts name resolution by querying a DNS server on the network.
