Ruckus Certified Network Integrator (RCNI) — Question 24

As an IP packet is routed across subnets, which value gets updated at each hop?

Answer options

• A. destination MAC address
• B. destination IP address
• C. source IP address
• D. subnet mask

Correct answer: A

Explanation

The destination MAC address is updated at each hop because it needs to reflect the MAC address of the next-hop router. The destination IP address remains unchanged as it is meant for the final destination, while the source IP address and subnet mask also do not change during routing.
