Which of the following describes the BEST device to configure as a DHCP relay?
The best device to configure as a DHCP relay is a router. DHCP relays are used to forward DHCP packets between clients and servers that are not on the same physical subnet or broadcast domain. Routers typically have built-in support for DHCP relay functionality and can efficiently handle this task, making them the most suitable device for this purpose among the given options.
A layer 3 switch would have received my vote but not a Data Link layer 2 switch. Routers, IP assignments (DHCP) occur at network layer.
Up vote this statement: "IP assignments (DHCP) occur at network layer."
I was thinking that it was B - Router but actually the offered answer C is ok. Can you configure layer 2 switch as DHCP relay? Yes, it is possible to configure a layer 2 switch to act as a DHCP relay. In order to do this, you will need to configure the switch to forward DHCP requests from clients to a DHCP server on another network. This is typically done using the "ip helper-address" command. For example, if the IP address of the DHCP server is 10.0.0.1, you would configure the switch as follows: ip helper-address 10.0.0.1 This will cause the switch to forward any DHCP requests it receives from clients to the DHCP server at 10.0.0.1. The DHCP server will then respond to the request and provide the client with an IP address and other necessary configuration information. It's worth noting that this configuration will only work if the switch is connected to both the client and the DHCP server via separate network segments. If the switch is connected to both the client and the DHCP server on the same network segment, the DHCP request will not be forwarded.
Well, I don't know about your argument. But surely, this is not the BEST way of configuring DHCP relay?! It has to be B, a router.
It cannot be a L2 switch. It has to be across networks and L2 switches cannot do that.
It's worth noting that while many Layer 2 switches support DHCP relay, some very basic switches might not have this feature. In such cases, you might need to consider using a Layer 3 switch or a router to perform DHCP relay functionality.
https://community.cisco.com/t5/switching/does-ip-helper-address-work-on-a-layer-2-switch-2950/td-p/1816526 While it can be done. It is not recommended. Especially if there is a Layer 3 swtich or a router as an alternative option. BEST ANSWER: B Router
A router is the best device to configure as a DHCP relay. This is because routers typically have built-in support for DHCP relay and can forward DHCP requests from multiple devices on a network to a DHCP server. This allows for efficient network management and configuration.
The best device to configure as a DHCP relay is a router. A DHCP relay is a host or router that forwards DHCP packets between clients and servers that are not on the same physical subnet or broadcast domain.
Has to be B
B. Router. A router is typically used as a DHCP relay, which allows DHCP clients on one network segment to receive DHCP address assignments from a DHCP server on a different network segment. The router acts as a relay agent, forwarding DHCP messages between the clients and the server. The router must be configured to forward DHCP messages and to act as a DHCP relay agent.
Router is the correct answer here.
Even Prof Messer in his videos demonstrates that a Router is configured to transmit the DORA processed OUTSIDE the local communication (LAN/WLAN) as relay (intermediary device, MITM, you get the ideea).
L2 Switch has no routing table to route to DHCP server
I think it must be router
The BEST device to configure as a DHCP relay is a: B. Router. A DHCP relay agent is used to forward DHCP messages between clients and servers when they are on different subnets. Routers are commonly used for this purpose. When a router is configured as a DHCP relay agent, it listens for DHCP requests on one interface and forwards them to a DHCP server on another interface. While a layer 2 switch (option C) is primarily concerned with forwarding frames at Layer 2, it does not typically operate at Layer 3 and is not designed for routing or DHCP relay functions. A bridge (option A) is also a Layer 2 device, and a hub (option D) is a simple networking device that operates at Layer 1. Routers are the most suitable devices for DHCP relay functions among the options provided.

DHCP relay agent can be configured to provide forwarding of DHCP traffic between subnets. Routers that can provide this type of forwarding are described as RFC 1542 compliant.
This is why you CANNOT always trust every answer in this dump, when in doubt ALWAYS go with the community answer. Layer 2 switch does not do DHCP.
The question didnt ask the switch to be a DHCP server, just to relay the messages. Most switches can act as a DHCP relay (IP_Helper) and pass the messages out to a configured port (most likely connected to a L3 device)
Actually not really "most" switches. Just L3 ones. Not a great answer to be honest. Stick with B: Router
A DHCP relay is typically configured on a router to forward DHCP requests from clients on one subnet to a DHCP server on another subnet. Therefore, the correct answer is: B. Router
Router, because this is where the relay is done
Please note that a DHCP relay agent can be a L3 Switch or a router. It has to forward the DHCP Discovery traffic to another network and a L3 switch also can do it. But here it had L2 switch and it CANNOT do that
