During BGP configuration on a router that has peered with other BGP speakers, the BGP command aggregate-a ddress 172.32.0.0 255.255.252.0 is issued. However, the peers do not receive this aggregate network in BGP advertisements. Also, the router does not have this aggregate network in its BGP table.
Which option indicates a possible reason this command did not cause the router to advertise the aggregate network to its peers?（）
A. Interface NULL 0 is likely shutdown.
B. The next hop IP address must be a loopback address.
C. The BGP command no auto - summary is missing.
D. The BGP command no synchronization is missing.
E. Subnets of 172.32.0.0/22 do not exist in the BGP table.
F. The IGP running on this router does not have network 172.32.0.0/22 installed.

Refer to the exhibit. Router RT - 1 and router RT - 2 both advertise network 131.25.0.0/16 to router
RT - 3 via internal BGP. What is the reason that router RT - 3 chose router RT - 1 as its best path to
network 131.25.0.0/16.（）
A. It has a better router ID
B. It advertises a lower autonomous system
C. It advertises t he best AS - path
D. It advertises the best local preference
E. It advertises the best origin code
F. It advertises the best MED
Refer to the exhibit. Router RT - 1 chooses one path to network 198.133.219.0/24. Indicate the reason Router RT - 1 choos es this "best" path. （）
A. In making its decision about the best path, RT - 1 gives precedence to the BGP MED values.
B. RT - 1 prefers internal BGP routes.
C. In making its decision about the best path, RT - 1 gives precedence to the origin code.
D. In makin g its decision about the best path, RT - 1 prefers the IGP metrics.
E. IP address 128.107.254.2 is lower than 128.107.255.2.
F. IP address 128.107.2.2 is lower than 128.107.255.2.
Refer to the exhibit. On the basis of the configuration that is provided, how would the BGP updates that come from router R1 be replicated inside autonomous system 65200？（）
A. All BGP updates that are received on router R 2 will be sent to routers R3 and R4. Routers R3 and R4 will then forward those BGP updates to router R5
B. None of the BGP updates that are received on router R2 will ever be received by router R5
C. All BGP updates that are received on router R2 will not be sent to routers R3 and R4
D. All BGP updates that are received on router R2 will be sent directly to router R5
A. 228.10.10.7
B. 229.11.10.7
C. 229.138.10.7
D. 229.138.10.8
E. 228.10.10.8
F. 228.10.138.7
A router has two paths to reach another network in a different autonomous system. Neither route was generated by the local router and both routes have the same default weight an d local preference values.
Which statement is true about how BGP would select the best path?（）
A. To influence one route to be preferred, its default local preference value will be changed via the use of the command bgp default local - preference 50
B. Th e router will prefer the shortest autonomous system path
C. If the command bgp always - compare - med has been given, then the router will prefer the route with the highest MED
D. The router will prefer the route with the lower MED
