LAST WEEK'S ANSWER:
Answer: b
Topic Domain: 4a
Issues:
How is the cost calculated at R1 for this route given the redistribution
statement shown in the Exhibit?
Solutions:
Here the metric type is set to E1. The default seed metric is used which
is 20. The cost on R1 will be the cumulative cost of each router hop
exit interface to get to the prefix plus the seed metric cost. The exit
cost on R1 is 195, on R2 it is 195 and then the seed metric is added
(20) for a total metric on R1 of 410.

10.X.X.X route as it would appear on R1?
a. 20
b. 410
c. 390
d. 800
e. 780

THIS WEEK'S QUESTION:
4-11-5. Examine the topology shown in Exhibit 1. Router A has lost
information for the 10.10.0.0 network. Router A possesses no feasible
successor route for the lost network. How will EIGRP react if all
routers are in the default EIGRP configuration?
a. Router A will not send a query as the network is directly
connected
b. Router A will query Router B, if Router B has no information
about the route, the query stops
c. Router A will query Router B, if Router B has no information
about the route, Router B queries Router C and Router D
d. None of these options are correct
