CCNA: Cisco Certified Network Associate — Question 1081

What does a router do when it is configured with the default DNS lookup settings, and a URL is entered on the CLI?

Answer options

• 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.

Correct answer: D

Explanation

The correct answer is D because the router, when configured with default DNS settings, will attempt to resolve the URL by querying a DNS server on the network. Options A and B are incorrect as they describe actions that do not occur in this context, and option C is incorrect because the router does not prompt for an IP address in this scenario.
