In a PIM-SM environment, which mechanism determines the traffic that a receiver receives?

A. The receiver explicitly requests its desired traffic from the RP on the shared tree.

B. The receiver explicitly requests traffic from a single source, which responds by forwarding all traffic.

C. The RP on the shared tree floods traffic out of all PIM configured interfaces.

D. The receiver explicitly requests traffic from each desired source, which responds by sending all traffic.

Refer to the exhibit.

A. MED

B. local preference

C. origin

D. weight

Refer to the exhibit.

A network operator is troubleshooting TE tunnels and discovers that the soft preemption is not working as desired. Where should the soft preemption be applied to solve the issue?

A. on the tail-end device for tunnel-te1 192.168.0.7

B. under the tunnel-te1 interface on PE1

C. explicitly for tunnel-te 1 under the Cisco MPLS TE configuration mode after the timeout setting

D. Under the interface Loopback0 necessary for this deployment type.

Refer to the exhibit.

Routers CE1 and CE2 are in AS 65530. which is multihomed for Internet access.

An engineer expects inbound traffic to AS 65530 to arrive from PE1. but it is coming from PE2 instead PE1 and PE2 routers are connected with CE routers through the same bandwidth

Which action must be taken to correct the problem?

A. On router CE2, configure inbound routes from PE2 to CE2 with a local-preference value of 50 or greater.

B. Configure router CEI to prepend the AS path to routes it receives from PE 1.

C. Set the local-preference value on router CEI to 100 or greater

D. On router PEI , change the origin for routes that are redistributed from CEI to CE2.

Refer to the exhibit.

MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

1.

Cisco Express Forwarding Is enabled on all routers.

2.

All routers reach all networks via OSPF.

3.

MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2. Which action resolves the issue?

A. On router R4, remove the mpls ip command on the s/O/O/2 interface.

B. On router R2, configure the mpls ip command on the SIO/O/4 interface.

C. On router R4, configure the mpls label protocol Idp command on all serial interfaces.

D. On router R2, configure the mpls label protocol Idp command on the interface.

Refer to the exhibit.

A service provider has LDP and segment routing running in the network. Mobility traffic is carried through LDP and enterprise traffic is carried through segment routing. Which configuration must be implemented to connect the bank branch with the HUB site on routers?

A. Configure segment-routing Sr-prefer prefix-list on AG1 and AG2 router for 10.10.10.10/24.

B. Enable segment-routing Mpls Sr-prefer on CR1 and CR2 routers for 10.0.0.0/8.

C. Enable segment-routing Mpls Sr-prefer on AG1 and AG2 routers for 10.0.0.0/8.

D. Configure segment-routing sr-prefer prefix-list on CR1 and CR2 routers for 10.20.20.10/24.

Refer to the exhibit A. R1# ip msdp sa-filter in 192.168.3.1

Router R1 is configured to advertise outgoing SA messages to routers R2 and R3, but to receive incoming SA messages only from R2. Which additional configuration must an engineer apply to router R1 so it filters all MSDP SA messages from Domain-C?

B. R3# ip msdp sa-filter out 192.168.3.1

C. R3# ip msdp password peer 192.168.1.1

D. R1# ip msdp password peer 192.168.3.1

Refer to the exhibit.

The UserA device fails to receive IPTV streaming traffic from the source. While debugging the issue, a network engineer finds that routers RB and RC receive the multicast traffic normally. RC receives subscription messages from UserA to join the IPTV stream. Which action must the engineer take on router RA to correct this problem?

A. Change ip igmp version 2 to ip igmp version 3 on interface GigabitEthernet 1/0.

B. Remove the ip pim ssm default configuration and replace it with ip pim rp-address 10.10.10.3.

C. Configure ip pim bidir-enable in global mode and add ip pim rp-address 10.10.10.3.

D. Configure ip pim ssm with ip igmp version 2 on interface GigabitEthernet 1/0.
