Refer to the exhibit. Router RT-1 chooses one path to network 22.214.171.124/24. Indicate the reason Router RT-1 chooses this “best” path.
A. In making its decision about the best path, RT-1 gives precedence to the origin code.
B. In making its decision about the best path, RT-1 gives precedence to the BGP MED values.
C. IP address 126.96.36.199 is lower than 188.8.131.52.
D. In making its decision about the best path, RT-1 prefers the IGP metrics.
E. RT-1 prefers internal BGP routes.
F. IP address 184.108.40.206 is lower than 220.127.116.11.
Correct Answer: A
Refer to the exhibit. Router RT-1 and router RT-2 both advertise network 18.104.22.168/16 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 22.214.171.124/16.
A. It advertises the best AS-path.
B. It advertises the best origin code.
C. It advertises the best MED.
D. It advertises the best local preference.
E. It has a better router ID.
F. It advertises a lower autonomous system.
Correct Answer: E
During BGP configuration on a router that has peered with other BGP speakers, the BGP command aggregate-address 126.96.36.199 255.255.252.0 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 BGP command no synchronization is missing.
C. The BGP command no auto-summary is missing.
D. Subnets of 188.8.131.52/22 do not exist in the BGP table.
E. The IGP running on this router does not have network 184.108.40.206/22 installed.
F. The next hop IP address must be a loopback address.
Correct Answer: D
Refer to the exhibit. It is desired to set up a BGP neighbor relationship between routers R1 and R4. BGP packets between them could travel through R2 or R3. What is the simplest configuration that will allow for failover?
A. Configure BGP neighbor relationships between all interfaces on R1 and R4
B. Install a direct connection between R1 and R4.
C. Configure loopback interfaces on R1 and R4 to provide the update source address for BGP packets.
D. Configure only one neighbor relationship between R1’s 192.168.1.2 interface and R4’s 172.16.10.2 interface.
Correct Answer: C
Which BGP option is required when load sharing over multiple equal-bandwidth parallel links from a single CE router to a single ISP router over eBGP?
A. eBGP Multipath
B. eBGP Multihop
C. BGP Synchronization
D. Public AS numbers
Correct Answer: B
