Refer to the exhibit. There is a BGP traffic path issue between Customer-1 and Customer-2.
Users from Customer-2 have reported file transfer issues. High utilization on the path between both customers causes many packet drops. Which configuration resolves the issue?

Refer to the exhibit The branch office in area 10 is connected to HQ via Frame Relay uplinks with bandwidth constraints After a recent implementation of QoS on the R2 and R3 networks the system has been logging %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x224E321, alignment 0 messages To reduce traffic load and memory utilization on R2 and R3 the network engineer configured R1 to announce only one user subnet per location by issuing the summary address 192.168.0.0 255.255.248.0 command en R1 However, the engineer noticed that router R2 still has two routes and a summary address from HQ and R3 also has two routes from HQ Which two actions must the engineer take on R1 to fix the issue so that only one route is announced' (Choose two.)

• A.Redistribute both routes into the ISIS process.
• B.Configure RI as a Level 1 device.
• C.Configure a summary route for Level 1-Level 2 devices.
• D.Configure the subnet range with the network command under the IS-IS process.
• E.Configure a summary route for Level 1 devices.

R1 is expected to receive routes originating from AS 65516 and from any ASs that are directly attached to it.
However, R1 is receiving routes only from AS 65516. Which action corrects the configuration?

• A.Add the regular expression ^$. in the AS-path filter to permit the traffic from R2.
• B.Change the regular expression in the AS-path permit filter to ^65516_[0-9]*$.
• C.Change the regular expression in the AS-path permit filter to _65516_.
• D.Change the regular expression in the AS-path permit filter to .*.

Refer to the exhibit. All routers in the network are in area 12, with IS-IS running in the default configuration as the IGP. To avoid congestion on the link from R1 to R2, the network architect planned for traffic from R1 to R3 to pass through R4. To meet the requirement, a network engineer set the metric from R1 to R4 to a cost of 15, but the traffic is still travelling through R2.
Which action must the engineer take to resolve the issue?

• A.Change the cost on the link from R1 to R4 to 5.
• B.Change the IS-IS administrative distance to 10.
• C.Change the cost on the link from R1 to R2 to 11 and enable narrow metrics.
• D.Change the default metric to 20 on all links and disable wide area metrics.

What is the purpose of the confederation identifier in a BGP confederation?

• A.It reflects the route reflector cluster ID within the confederation.
• B.It carries the AS number within the confederation's local autonomous system.
• C.It advertises routes outside of the confederation's autonomous system.
• D.It identifies the autonomous system that belongs to the confederation.
