Refer to the exhibit An engineer is troubleshooting a networking issue with several symptoms The shortest path from router R1 to R8 is underused and the longest path is overused Traffic from 10.1.1 1 to 10 8 8 8 is routed on the longest path Traffic between the R1 and the application server is experiencing packet drops and latency problems.
Which action resolves the issue?
Drag and drop the features about multicast from the left onto the multicast protocols on the right. Not all options ate used.

Refer to the exhibit.

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 network operator is troubleshooting packet loss seen from the R1 loopback interface to the R2 loopback interface over the core network. The operator is attempting to identify the next leg in the path from PE1.
Which interface and label path should the operator investigate next?
