Refer to the exhibit. Which three statements are true? (Choose three.)

A.
On the routing table of R4, the 10.1.1.0/24 route appears as an O E2 route.

B.
On R4, the 172.16.1.0/24 route has a metric of 20.

C.
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.

D.
The administrative distance of the 172.16.1.0/24 route in the routing table of R3 is 170.

E.
On R5, the 4.0.0.0/8 route will have an administrative distance of 120 and a hop count of
6.

Explanation:
When redistributing into OSPF, the default route type is E2 -> A is correct. Notice that the
cost of E2 type is always the cost of external route only.
Also, the default seed metric when redistributing into OSPF is always 20 (except for BGP,
which is 1) -> B is correct.
When redistributing into EIGRP, the external EIGRP routes have an administrative distance
of 170 by default -> D is correct.
