What is the purpose of using First Hop Redundancy Protocol on a specific subnet?
Answer: A
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.

Refer to the exhibit. Which configuration issue is preventing the OSPF neighbor relationship from being established between the two routers?
Answer: C
C is absolutely right. Yes, I've experienced this in the field on several occasions ..an odd issue but a definite sneak up and bang factor - your tunnel and consistent traffic be done. https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/116119-technote-ospf-mtu-00.html#:~:text=In%20this%20example%2C%20the%20routers%20have%20GigabitEthernet%20interfaces%20with%20an%20MTU%20set%20to%202000.%20The%20MTU%20of%20the%20L2%20switch%20is%20only%201500%20bytes https://www.reddit.com/r/networking/comments/k9hr35/ospf_mtu/

Refer to the exhibit. When router R1 is sending traffic to IP address 10.56.192.1, which interface or next hop address does it use to route the packet?
Answer: A
Cannot be Vlan57 10.56.128.0/18 = 255.255.192.0 | Block Size = 64 increments until you pass the target our target IP is 10.56.192.1 so:- 10.56.128.0 and next network is 10.56.192.0 | The last IP is right before the next network and that is 10.56.191.255 and the last valid IP is right before our Broadcast address that is 10.56.191.254 so it our vlan57 network does not fall to our target IP. If you are wondering there is 16384 subnets, 2^32 - CIDR (18) = 2^14 = 16384.

DRAG DROP - Drag and drop the application protocols from the left onto the transport protocols that it uses on the right. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Refer to the exhibit. Load-balanced traffic is coming in from the WAN destined to a host at 172.16.1.190. Which next-hop is used by the router to forward the request?
Answer: C
Simple way to look at it: /29 = 8 IPs, 182-191, 190 is the last Assignable IP on that Subnet, so /29 is picked because it is the Longest Prefix route INCLUSIVE of the IP address. And the next hop IP for that is C. 192.168.7.35

Refer to the exhibit. Routers R1 and R3 have the default configuration. The router R2 priority is set to 99. Which commands on R3 configure it as the DR in the 10.0.4.0/24 network?
Answer: D
This is not spanning tree protocol where 0 becomes the highest priority. In the case of OSPF, 0 means you will never be elected as DR or BDR. Default priority is 1.

Refer to the exhibit. A network engineer must configure R1 so that it sends all packets destined to the 10.0.0.0/24 network to R3, and all packets destined to PC1 to R2. Which configuration must the engineer implement?
Answer: C
Am I the only one notice that the netmask of R1(config)#ip route 10.0.0.5 255.255.255.255 172.16.0.2 should be changed to 255.255.255.0?

Refer to the exhibit. All traffic enters the CPE router from interface Serial0/3 with an IP address of 192.168.50.1. Web traffic from the WAN is destined for a LAN network where servers are load-balanced. An IP packet with a destination address of the HTTP virtual IP of 192.168.1.250 must be forwarded. Which routing table entry does the router use?
Answer: D
Dont get confused by reading first part of questions, basically CCNA exam creators want you to focus in the beginning of the question which has nothing to do with finding the answer. You need to keep reading until the last part of the question. This dumps are good way to practice, thanks a lot guys
