Exam 200-301 topic 1 question 437 discussion

I have no idea what is the benefit of twisting words to come up with complicated question, which will not serve in real life. The purpose of FHRP is to provide redundancy for the gateway. PERIOD! Anyway, I'm going with option A.

Well, among the answers, A is the least incorrect, as I don't think that forwarding multicast hello messages between routers is the PURPOSE of using a First Hop Redundancy Protocol. The other answers refer to other protocols: Answer B refers to a DHCP server Answer C refers to STP Answer D refers to ACL

When a FHRP protocol is used, the actual active/master router sends a gratuitous ARP to all the devices(Switches/hosts) on the network to advertises its MAC address and declare as the default router, as this been said, the most correct answer should be B

in FHRPs protocols when the active or master router take the role of packet forwarding outside of the local network, it will send an Gratuitous ARP message as the broadcast message to all hosts to let them know the mac address of default gateway of the network which is up at that time this will happen each time the active or master role is come up or taken by a router. so B is the better answer

As VRRP resolves the virtual IP of the D.G. with its MAC, in tra ARP process, VRPP is actually "sending the default route to the hosts"... Isn't it? So B.

Is this really a CCNA question? I suspect this is generated by ChatGPT.

Another typical Cisco nonsense BS. None of the answers is a purpose of FHRP.

FHRPs, such as HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol), ensure that hosts have a consistent default gateway even if one of the routers fails. This redundancy helps maintain network connectivity without causing loops.

The purpose of using a First Hop Redundancy Protocol (FHRP) on a specific subnet is to provide redundancy for the default gateway (router) on that subnet. This ensures that if the primary router fails, another router in the network can seamlessly take over the routing responsibilities, minimizing downtime and ensuring continuous network connectivity for the hosts on the subnet.

it´s A This is how FHRPs Work, a virtual IP address is commonly shared between the default router and the backup router. All the PCs present in the network can be configured to use that virtual IP address to use as their default gateway instead of the actual IP address of the default router. This has to be discussed by the two routers. They do so by sending multi-cast “Hello” messages to each other. The roles that these two routers discuss are: One of the routers becomes the active router, the other router becomes the standby router. Therefore, the active router will act as the default gateway for the traffic in a subnet. This means that the stanby router will not function until the active fails.

Has to be A for me FHRPs use multicast hello messages to maintain communication and detect failures. These protocols ensure seamless failover when the primary router is unavailable Why its NOT B First Hop Redundancy Protocols (FHRPs), such as HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol), do not directly send a default route to hosts. FHRPs provide redundancy for the default gateway (router) in a network. The virtual IP address (shared by FHRP routers) serves as the default gateway for hosts. Hosts are configured with this virtual IP address as their default route.

It's a terrible question, but I am going with B. Why? 1. A isn't a "purpose", it's a feature. 2. FHRP's don't "forward" multicast hello messages, they simply send them to each other within the subnet. 3. B is more in line with the idea of a "purpose", i.e. *why* you would use a FHRP, and with some interpretation isn't entirely wrong. When one router fails, gratuitous ARP is used to update the MAC address, thereby changing the "route" packets take out of the network by updating the CAM table on the switch. The whole question is 100% BS but B takes it IMO.

A is the answer , but why someone would call it a "purpose" ? Only for you to fail..... The only purpose of FHRP is in the name : provide one hop redundancy , isn't it ?

Answer is B a stable routing.

Poorly worded question but HSRP sends hello packets between each other to ensure that the routers are up but this is not the reason for HSRP

Some of these quetions by Cisco are really poor. The purpose of FHRP is simply for redundancy. I picked A but It was a lucky guess between that and B if im honest!

A is correct. FHRPs do not forward the default gateway to hosts.
