Successor route's RD is less than FD

Non-successor route's FD is less than the FD

Successor route's FD is less than RD

Question 13 of 50

14. When EIGRP successor route fails on the router that doesn't have a feasible successor route, it moves to active state on that router. The router then tries to find other valid routes to the destination. To do so, it sends EIGRP Query messages to every neighbor except the neighbor that advertised this failed route.

Which of the below is valid action from these neighbors when they receive the Query message?

If the neighbor itself is active on this route, it immediately sends an EIGRP Reply back to the original router before waiting on replies to its own set of Query messages.

If the neighbor itself is active on this route, it does not forward the Query message to neighboring routers as it has no problem.

If the neighbor is passive on this route, it forward the Query message to neighboring routers.

If the neighbor is passive on this route, it sends an EIGRP Reply message, telling the original router that it does have a loop-free route.

Question 14 of 50

15. What will an EIGRP router do when it receives an EIGRP Query for a prefix/prefix length and it only has a summary route that includes the prefix/prefix length?

It send a Query message to neighbor routers.

It insert the route in its routing table in ACTIVE state.

It immediately sends an EIGRP Reply and does not flood the Query to its own neighbors.

It doesn't reply to the sender as it doesn't have that prefix in its EIGRP database.

The route-map includes an implied deny all clause at the end.

Routes matched by the match command in route-map with the deny option are allowed through.

Route-map clause can match by referring to an ACL but not prefix-list

Question 18 of 50

19. Which of the below is correct about route summarization in OSPF and EIGRP?

OSPF doesn't support route summarization while EIGRP support route summarization.

Only the route 10.0.0.0/8 will be advertised to R2.

The routes 10.1.1.0/24, 10.3.0.0/16, 10.0.0.0/8 and 10.1.2.0/24 will be filtered.

The routes 10.1.1.0/24 and 10.1.2.0/24 only will be advertised to R2.

No routes will be advertised to R2.

Question 42 of 50

43. Routers, R1,R2,R3 and R4 are connected to the same LAN segment 10.0.0.0/24 and OSPF is enabled on the four routers. The four routers has OSPF enabled on all interfaces and advertise their subnets in OSPF. i.e 10.0.1.0/24, 10.0.2.0/24, 10.0.3.0/24 and 10.0.4.0/24. R4 was the last powered up router.

R3 can't route traffic to the subnet 10.0.4.0/24. Why?

R3 is elected as the DR and R4 is neither DR nor BDR.

As R4 was the last powered up router, it didn't join the DR and BDR election and then can't advertise its OSPF routes.

There is configuration conflict between R1 and R4.

The network 10.0.4.0/24 is a non-backbone area and routes originated in non-backbone area can't be forwarded to other non-backbone area

Question 43 of 50

44. Your colleague in the network team assigned OSPF Interface Cost on each router interface as show on this diagram.

Which Path will router R1 choose to send traffic to a host in the network 10.1.1.0/24?

R1-R2-R5

R1-R3-R5

R1-R4-R5

R1 will load-balance on the three paths

Question 44 of 50

45. You are just hired in a new company and your manager assigned a task for you to make sure that R1 in the below network can reach the network 10.10.10.0/24. Study the diagram and routers configuration carefully and suggest what to do to make sure that traffic reaching R1 destined to the network 10.10.10.0/24 can be routed in this network.

You must change OSPF process ID of R3 from 3 to 1

Change Area 1 from NSSA to normal area

You must remove passive interface configuration of R3

You shouldn't change any configuration. R1 can route traffic towards the network 10.10.10.0/24 normally.

Question 45 of 50

46. In the below diagram, all Blue lines are Gig Ethernet interfaces and all red lines are Fastethernet Interfaces. All interface OSPF cost are default values calculated by each router. What path will the traffic destined to R1's Lo1 interface take starting at R5?

R5-R4-R2-R1

R5-R4-R3-R2-R1

There is a routing loop in this network

Question 46 of 50

47. A junior engineer connected the shown network and configured the routers as below. Your team manager assigned a task for you as the senior network engineer to revise the topology and configuration and make sure that hosts connected to devices in OSPF domain can reach hosts on the network 10.1.1.0/24.

What must be done to achieve full reachability to the network 10.1.1.0/24?

Configure one direction redistribution only between OSPF and EIGRP.

Configure route filtering when redistributing between OSPF and EIGRP.

Advertise the network 10.1.1.0/24 by the network command rather than redistribution in EIGRP configuration on R1.

The network 10.1.1.0/24 is reachable normally from OSPF domain. Nothing should be done.

Question 47 of 50

48. The User in the below diagram started his PC and is configured to get his IP address through DHCP server.

R1 is configured to relay DHCP requests to the DHCP server. DHCP scope 10.10.10.0/24 is created on the DHCP server and the user expects to get an IP address in this range but it fails. According to the shown R1 and R2 configuration, what is the problem?

The routing on R2 refers to wrong next hop

There is no valid route on R2 to reach the network 10.10.10.0/24 to route back DHCP reply

The " ip helper-address 10.2.2.10" command should have the "secondary" keyword added to it.

DHCP request source IP address is the primary IP address on R1's interface f0/0

Question 48 of 50

49. Your company leased two Internet connections from two different providers as shown in the below diagram. Your manager asked you to configure load-balancing for outgoing traffic towards the two networks 10.1.1.0/24 and 10.2.2.0/24 over the two links. Which of the below statements are correct about this network setup?

Load-balancing can be achieved through the use of AS prepending.

Load-balancing is not an option and only load-sharing can be achieved.

BGP "maximum-paths" command should be combined with AS prepending to achieve load-balancing

Per packet load-balancing can be configured if all the three devices are Cisco routers.

Question 49 of 50

50. You configured the below EIGRP network with the shown metrics on each link between the routers. In order increase the bandwidth used to route traffic from R1 to network 1 you configured variance of 3 on R1. Which of the below statement is the correct one?
