CCNA: Cisco Certified Network Associate — Question 1068

A DHCP pool has been created with the name NOCC. The pool is using 192.168.20.0/24 and must use the next to last usable IP address as the default gateway for the DHCP clients. What is the next step in the process?

Answer options

• A. next-server 192.168.20.254
• B. network 192.168.20.254 255.255.255.0 secondary
• C. default-router 192.168.20.253
• D. ip default-gateway 0.0.0.0 0.0.0.0 192.168.20.253

Correct answer: C

Explanation

The correct answer is C, as it correctly sets the default gateway for clients to the next to last usable IP address, which is 192.168.20.253. Option A is incorrect because it defines a next-server for PXE booting, which is unrelated to setting a default gateway. Option B incorrectly uses a secondary network command, and option D is incorrectly formatted for setting a default gateway.
