CCNA: Cisco Certified Network Associate — Question 297

A network engineer must configure the router R1 GigabitEthernet1/1 interface to connect to the router R2 GigabitEthernet1/1 interface. For the configuration to be applied, the engineer must compress the address 2001:0db8:0000:0000:0500:000a:400F:583B. Which command must be issued on the interface?

Answer options

• A. ipv6 address 2001::db8:0000::500:a:400F:583B
• B. ipv6 address 2001:db8:0::500:a:4F:583B
• C. ipv6 address 2001:db8::500:a:400F:583B
• D. ipv6 address 2001:0db8::5:a:4F:583B

Correct answer: C

Explanation

The correct answer is C, which effectively compresses the given IPv6 address by removing unnecessary zero groups. Options A and B incorrectly use double colons and do not maintain the proper structure of the IPv6 address, while option D also compresses incorrectly by not following the standard rules for IPv6 address notation.
