ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 2

Which command can you enter to verify that a 128-bit address is live and responding?

Answer options

• A. traceroute
• B. telnet
• C. ping
• D. ping ipv6

Correct answer: C

Explanation

The correct answer is C, as the 'ping' command is specifically designed to check the reachability of a network host by sending ICMP Echo Request messages. Options A and B do not serve this purpose; 'traceroute' is used for path discovery and 'telnet' is primarily for remote login. While D is also a valid command for IPv6 addresses, it is less general compared to 'ping', which applies to both IPv4 and IPv6.
