What is the purpose of the eigrp stub configuration command?

• A.to reduce the convergence time by enabling the EIGRP stub router to propagate the EIGRP queries from the EIGRP hub router
• B.to reduce the convergence time by enabling the EIGRP stub router to also perform query requests to the EIGRP hub router
• C.to increase scalability by limiting the EIGRP query range
• D.to reduce the size of the routing table by blocking the D EX (External EIGRP) routes into the EIGRP stub router

Refer to the exhibit.

Which three statements are true? (Choose three.)

• A.The administrative distance of the 172.16.1.0/24 route in the routing table of R3 is 170.
• B.On R5, the 4.0.0.0/8 route will have an administrative distance of 120 and a hop count of 6.
• C.On R4, the 172.16.1.0/24 route has a metric of 20.
• D.On the routing table of R4, the 10.1.1.0/24 route appears as an O E2 route.
• E.The R3 S0/0 interface should not need the no ip split-horizon eigrp 1 configuration command for the 172.16.1.0/24 route to appear in the routing table of R2 as an D EX route.
