What is the primary purpose of ICMP?

To synchronize clocks between devices

To report errors and provide diagnostic information in IP networks

To transfer files between network devices

To assign IP addresses to clients

A network admin is troubleshooting why a user cannot reach a file server. The admin runs ping from the user's PC to the server's IP address and receives 'Request timed out.' The admin then tries to open a web page on the same server and it loads successfully. What is the most likely explanation?

The server is offline and the web page is cached locally

The server is blocking ICMP echo requests but allowing TCP port 80

The user's PC has a firewall blocking all outgoing TCP traffic

The server's IP address is incorrect and the web page is on a different host

What is the primary function of DNS?

To assign IP addresses to devices automatically

To translate human-readable domain names into IP addresses

To encrypt data transmitted over the internet

To transfer files between a client and a server
