— Exhibit –Referring to the exhibit, route 200.200.200.0/24 is exported into BGP and the peering routers use
default BGP policies.
Which statement describes the advertisement for the 200.200.200.0/24 route?

Refer to the Exhibit.

Referring to the exhibit, a packet sent from User A to User B will be forwarded out interface 0/0/23
using which source MAC address?

Refer to the Exhibit.

If all OSPF routers shown in the exhibit boot at the same time, which router will be elected as the
designated router?

Refer to the Exhibit.

Referring to the exhibit, a packet destined to 172.129.3.5 is sent from ISP X towards R1.
Which statement describes how R1 handles the packet?

Refer to the Exhibit.

Referring to the exhibit, note that R5 is exporting the 172.168.1.0/24 route into OSPF. Which LSA
type does R2 send to R4?

Refer to the Exhibit.

Referring to the exhibit, R1, R2, and R3 boot at the same time. Several minutes later, R4 boots.
After R4 has been online for 40 seconds, which router will be the OSPF designated router?

Refer to the Exhibit.
