Cisco Exam 200-301 Topic 2 Question 103 Discussion

Actual exam question for Cisco's 200-301 exam

Question #: 103
Topic #: 2

A HCP pool has been created with the name CONTROL. The pool uses the next to last usable IP address as the default gateway for the DHCP clients. The server is located at 172.16 32.15. What is the step in the process for clients on the 192.168.52.0/24 subnet to reach the DHCP server?

Aip forward-protocol udp 137

Bip default-network 192.168.52.253

Cip helper-address 172.16.32.15

Dip default-gateway 192.168.52.253

Show Suggested Answer

Suggested Answer: C

DHCP and broadcasts: DHCP clients use broadcasts to find a DHCP server, but broadcasts are typically limited to the local subnet. Since the DHCP server (172.16.32.15) is on a different subnet than the clients (192.168.52.0/24), the clients' broadcast requests won't reach it.

ip helper-address: This command is used on a router (or layer 3 switch) to forward DHCP broadcasts to a specific IP address (the DHCP server) on a different subnet. This allows clients to discover and obtain IP address information from a DHCP server that is not on their local network.

Ooh, this is a tricky one! I'm leaning towards C, but I can't help but wonder if the answer is actually a secret message from the exam creator, hidden in one of the options. *puts on tinfoil hat*

Haha, this question is a real brain-teaser! I'm going to go with C, just because it sounds the most technical. Plus, who doesn't love a good 'ip helper-address' command, am I right?

User 2: Agreed, that command is essential for clients on a different subnet to communicate with the DHCP server. Good choice!

I believe option C) is the best choice because it specifically directs the clients to the DHCP server.

I'm not sure, but I think B might be the right answer. Setting the default network to the last IP address on the subnet seems like it could work. *scratches head*

User 4: I think C is the best option. Setting the ip helper-address to the DHCP server's IP address should help clients on a different subnet reach the server.

I don't think so, because the default network is not the same as the helper address for DHCP.

But what about option B) ip default-network 192.168.52.253? Could that also work?

I agree with Corinne, using the helper address will allow the clients to reach the DHCP server.

D seems like the obvious choice here. Why would we need to forward the requests when we can just set the default gateway to the last usable IP address on the subnet?
