Q:

A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20684570. Another route is from OSPF with a metric of 852. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

A. the OSPF route
B. the EIGRP route
C. the RIPv2 route
D. all three routes
E. the OSPF and RIPv2 routes

Answer

Answer : B


Explanation :


This is one of those tricky questions just to test your knowledge of routing protocols and their administrative distance. Let’s look at the AD of popular routing protocols below:
 Routing Protocol (Source)                           AdministrativeDistance(AD)                                                             


  Directly connected                                        0


  Static Route                                                  1


  EIGRP                                                           90


  Summary Route(EIGRP)                              5


  OSPF                                                           110


  RIP                                                              120


Fom the above table, you can see that EIGRP has the lowest AD from all of the above mentioned routing protocols. So, the router will choose to use the routing protocol which has lowest Administrative Distance which in this case is B. EIGRP

Q:

As a Cisco technician, you need to know EIGRP protocol very well. Which of the following is true about EIGRP successor routes? (Choose two)

A. A successor route is used by EIGRP to forward traffic to a destination
B. Successor routes are stored in the neighbor table following the discovery process
C. Successor routes are flagged as "active" in the routing table
D. A successor route may be backed up by a feasible successor route

Answer

Answer : A  D


 


Explanation:


A and D are correct because successor route is the best and primary route to a remote network. A successor route is used by EIGRP to forward traffic to a destination and is stored in the routing table. Its backed up by a feasible successor route in case the primary route fails, that is stored in the topology table.


B is incorrect because neighbor table only contains a list of directly connected EIGRP routers that have an adjacency with this router, it doesn't contain successor routes.


C is incorrect because successor routes found in the routing table are not flagged as "active”
