Correct Answer: ABD
Question 5:
What is the difference between a source tree and a shared tree in a multicast environment?
A. To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.
B. A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.
C. To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.
D. Source trees are the default type for bidirectional PIM, and PIM-DM uses shared trees by default.
Correct Answer: B
Question 6:
DRAG DROP
Drag and drop the features about multicast from the left onto the multicast protocols on the right. Not all options ate used.
Select and Place:
Correct Answer:
Question 7:
Which statement about BFD on Cisco IOS XR Software is true?
A. Cisco IOS XR router must use LDP to route back to the Cisco IOS router to establish the peer relationship.
B. Cisco IOS XR Software does not support BFD multihop for IPv4.
C. Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.
D. BFD is not compatible between Cisco IOS XR and Cisco IOS Software.
Correct Answer: C
A router running BFD in Cisco IOS software can designate a router running BFD in Cisco IOS XR software as its peer using the bfd neighbor command; the Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.

Question 8:
Refer to the exhibit.
A network engineer is investigating a report of packet drops between the branch site and the central site.
1.
The two sites are connected via OSPF and RSVP-TE tunnels.
2.
Traffic from the central site to the branch site is passing normally.
3.
Technicians at both sites successfully ping the loopback IP addresses on routers R1 and R2.
Which configuration corrects the packet-drop problem?
A. R2(Config)# interface Tunnel333 R2(Config-if)# tunnel mpls traffic-eng bandwidth 33000
B. R1(Config)# interface Tunnel222 R1(Config-if)# tunnel mpls traffic-eng bandwidth 33000
C. R1(Config)# interface Ge0/0R1(Config-if)# ip rsvp bandwidth 33000 3300
D. R2(Config)# interface Ge0/0R2(Config-if)# ip rsvp bandwidth 33000 3300
Correct Answer: C
Question 9:
Refer to the exhibit.
All routers on this network have been configured with PIM-SM, and R1 is the rendezvous point. However, when asymmetric routing is implemented to modify link usage, the network begins to drop certain multicast traffic. Which action corrects the problem?
A. Place the routes affected by asymmetric routing in a VRF
B. Remove the asymmetric routing and use spanning tree to manage link usage
C. Add a static mroute for routes that are failing
D. Configure the routers to use PIM-DM instead of PIM-SM
Correct Answer: C
Question 10:
Refer to the exhibit.
A network operator is configuring BGP PIC on CE1 on already established neighborships with PE1 and PE2 inside the fully converged MPLS network. Which element needs to be implemented to make this feature function effectively?
A. Bidirectional Forwarding Detection must be applied to the upstream facing BGP interfaces
B. The operator must ensure that all prefixes have the same next-hop from PE1 and PE2 for BGP PIC
C. A reserved BGP community of 1:10 must be used to denote the PIC feature set to the routing protocol
D. BGP import/export policies must be applied on all devices for the routes needing BGP for PIC
Correct Answer: A
Question 11:
You have configured MSDP peering between two autonomous systems that pass traffic between two sites, but the peering has failed to come up. Which task do you perform to begin troubleshooting the problem?
A. Verify that multicast has been disabled globally
B. Verify that PIM-DM is configured on the source interface
C. Verify that both source interfaces are reachable from both peers
D. Verify that the two MSDP peers allow asymmetric routing
Correct Answer: C
Question 12:
Refer to the exhibit.
Company A established BGP sessions with several ISPs. A network engineer at the company must filter out all traffic except for routes that transit AS 152.
The engineer configured the filtering policy "permit 152S(_[0.9])" on R1, but after applying the configuration, the engineer notices that other routes are still visible.
Which action resolves the issue?
A. Add a second filtering policy in the format ip access-list 1 permit ^152_([0-9]+).
B. Add a second filtering policy in the format ip prefix-list 1 permit ^152^.
C. Change the filtering policy to ip explicit-path 1 permit $152^.
D. Change the filtering policy to ip as-path access-list 1 permit 152.
Correct Answer: A
Question 13:
Which cost is the default when redistributing routes from BGP to OSPF?
A. 20
B. 1
C. infinite
D. automatic
Correct Answer: B

Question 14:
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.
Correct Answer: A
A shared tree is built first between receiver and the RP. The receiver is then able to switch to a Source tree as needed.
Question 15:
Refer to the exhibit.
The green policy is designed with low delay, and the pink policy is designed with low cost. What is the next hop for node A on its way to node D, with the objective of achieving a low delay?
A. 192.168.3.2
B. 192.168.1.6
C. 192.168.3.6
D. 192. 168.1.2
