Question 21

Which two conditions must be met before separate ISPs can provide interdomain multicast routing? (Choose two.)

1. Each ISP must configure MSDP to connect its individual multicast administrative domain to the domains at other ISPs.
2. Each ISP must dedicate a single router to handle multicast traffic between providers.
3. Each ISP must replace its RP assignment with a global RP.
4. Each ISP must configure its network to use PIM-DM.
5. Each ISP must support intradomain multicast routing.

Question 22

An engineer is troubleshooting a connectivity issue across the MPLS network and is verifying the forwarding behavior of packets. Which table does the engineer look at to verify the forwarding behavior of an IP packet as it enters the MPLS network at the ingress LSR?

1. LFIB
2. LIB
3. RIB
4. FIB

Question 23

An engineer is troubleshooting end-to-end customer traffic across an MPLS VPN service provider network. Which tasks should the engineer use to solve the routing issues? Drag and drop the table types from the left onto the most useful troubleshooting tasks/router types on the right. (Not all options are used.) Select and Place:

Question 24

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?

1. Verify that multicast has been disabled globally
2. Verify that PIM-DM is configured on the source interface
3. Verify that both source interfaces are reachable from both peers
4. Verify that the two MSDP peers allow asymmetric routing

Question 25

Refer to the exhibit. Why is neighbor 10.1.5.5 stuck in "2WAY" state?

1. Router ID 10.1.5.5 is not reachable from R2
2. OSPF authentication has failed between R2 and 10.1.5.5
3. It is an expected behavior when OSPF network type is broadcast
4. OSPF parameters (Area ID or hello interval) are mismatched between R2 and 10.1.5.5
