A. ip default-network

B. ip default-gateway

C. default-information originate always

Correct Answer: C

Question 12

Refer to the exhibit.

Network administrators have set up a hub and spoke topology with redundant connections using EIGRP. However, they are concerned that a network outage between Router R1 and Router R2 will cause traffic from the 10.1.1.x network to the 10.1.2.x network to traverse the remote office links and overwhelm them. What command should be used to configure the spoke routers as EIGRP stub routers that will not advertise connected networks, static routes, or summary addresses?

A. no eigrp stub connected static

B. No additional command is needed beyond a default EIGRP configuration.

C. eigrp stub

D. eigrp stub connected static

E. eigrp stub receive-only

Question 15

Based on the exhibited output,

Which three statements are true? (Choose three.)

C. All the routes are in the passive mode because R1 is in the query process for those routes.

D. R1 will load balance between three paths to reach the 192.168.1.48/28 prefix because all three paths have the same advertised distance (AD) of 40512000.

E. The best path for R1 to reach the 192.168.1.48/28 prefix is via 192.168.1.66.
