  • R2 will advertise network with a hop count of 16 to R1.
  • R2 will not send any advertisements and will remove route from its routing table.
  • R1 will reply to R2 with the advertisement for network with a hop count of 16.
  • After communication fails and after the hold-down timer expires, R1 will remove the route from its routing table.
  • R3 will not accept any further updates from R2, due to the split-horizon loop prevention mechanism.


Question 6: Refer to the exhibit. The DHCP client is unable to receive a DHCP address from the DHCP server.


Consider the following output:

interface fastethernet 0/0

ip address

interface serial 0/0

ip address


ip route

Which configuration is required on the Router B fastethernet 0/0 port in order to allow the DHCP client to successfully receive an IP address from the DHCP server?

Question 11: The output of show ip eigrp topology on R1 shows this output related to subnet

P, 2 successors, FD is 2172419

How many feasible successor routes does R1 have for

Question 12: R1 is 3 router hops away from subnet According to the show interfaces commands, all three links between R1 and use the following settings: bandwidth: 1000, 500, 100000 and delay: 12000, 8000, 100. What delay and bandwidth value will be used to calculate the EIGRP metric?

Question 13: Routers R1 and R2 are EIGRP neighbors. R1 has been configured with the eigrp stub connected command. What will be the impact of the command on both routers?

Question 14: An engineer plans to configure summary routes with the ip summary-address <eigrp asn> <prefix mask> command. Which command, would create a summary that includes all four of the following subnets:,,, and

Question 15: Router R1 exists in an Enterprise that uses EIGRP as its routing protocol. The show ip route command output on router R1 lists the following phrase: “Gateway of last resort is to network”. Which is most likely to have caused this output to occur on R1?

Question 16: Router R1 directly connects to subnet with its Fa0/0 interface. R1 can ping four other working OSPF routers in that subnet. R1 is neither the designated router (DR) nor backup DR (BDR). OSPF is working correctly on all five routers. Which of the following is true on R1?

Show ip ospf neighbor will show how many neighbors in full and how many in 2 way state. Considering both DR and BDR are present.

Question 17: Routers R1 and R2 are OSPF neighbors using their Fa0/0 interfaces, respectively, using default settings for all timers. An engineer adds the ip ospf hello-interval 6 command to R1’s Fa0/0 configuration. How can we check the revised timers and what will be impact of changing the timer?

Question 18: List all the things that must or must not match for OSPF neighborship and adjacency formation.

Question 19: Which of the OSPF messages contains entire complete LSAs used during the database exchange process?

Question 20: R1, R2, R3, and R4 connect to the same LAN-based subnet. OSPF is fully working in the subnet. Later, R5, whose OSPF priority is higher than the other four routers, joins the subnet. Which of the following are true about the OSPF database exchange process over this subnet at this point?

  • R5 will send its DD, LSR and LSU to all DR router multicast address.
  • R5 will send its DD, LSR and LSU to all DR router multicast address.
  • DR will inform R5 about LSA by sending DD, LSR and LSU to all SPF-router multicast address
  • DR will inform R5 about LSA by sending DD, LSR and LSU to all SPF-router multicast address

Question 21: ABR R1 has been configured with an area 1 stub no-summary command. Which stubby area type is area 1?

Question 22: Why Redistribution is used in network?
