Question 1 of 35

Your network provider supports multicast traffic but your provider network does not. You want to allow multicast hosts outside of your network to receive multicast traffic sourced within your network.

How would you satisfy this requirement?

Use MSDP peering with your provider.

Use AutoVPN to connect to the remote hosts.

Use an MP-BGP session to your provider to pass multicast traffic.

Use automatic multicast tunnel gateway at the edge of your network.

Correct Answer: D

To allow multicast hosts outside of your network to receive multicast traffic sourced within your network, you can use an automatic multicast tunnel (AMT) gateway at the edge of your network. An AMT gateway encapsulates multicast traffic in unicast packets, allowing it to traverse networks that do not support multicast. This way, the multicast traffic can be delivered to the remote multicast hosts over networks that only support unicast.

Question 2 of 35

Click the exhibit.

Referring to the exhibit, traffic handled by the s-1 scheduler is out of profile.

Assuming bandwidth is available in this scenario, which statement is correct?

Traffic handled by the s-1 scheduler is serviced immediately after traffic being serviced by the s-4 scheduler.

Traffic handled by the s-1 scheduler is serviced immediately before traffic being serviced by the s-4 scheduler.

Traffic handled by the s-1 scheduler is serviced immediately before traffic being serviced by the s-2 scheduler.

Traffic handled by the s-1 scheduler is serviced immediately after traffic being serviced by the s-2 scheduler.

Correct Answer: A

Traffic handled by the s-1 scheduler, which has a high priority, would be serviced after traffic being serviced by the s-4 scheduler, which has a low priority, if s-1 is out of profile. In the Junos OS, out-of-profile traffic is serviced after in-profile traffic from all other schedulers. Since s-4 is in profile, s-1 would not be serviced until after s-4.

Question 3 of 35

Click the Exhibit.

Referring to the exhibit, which set of interfaces will be registered by MVRP?

ge-0/1/0, ge-0/1/1, ae0, ae1

ge-0/1/0, ge-0/0/2, ae0, ae1

ge-0/0/1, ge-0/1/1, ae0, ae1

ge-0/0/1, ge-0/0/2, ae0, ae1

Correct Answer: D

MVRP is disabled by default and is valid only for trunk interfaces. Examining the exhibit, the interfaces configured with port-mode trunk are ge-0/0/1, ge-0/0/2, ae0, and ae1. These interfaces will be registered by MVRP for proper VLAN registration and propagation.

Question 4 of 35

Click the Exhibit.

You are configuring a new BGP session between router1 and router2. The session does not establish.

Referring to the exhibit, what must be done to establish this session?

You must define the peer-as number on router2.

You must define the autonomous- system number under the [edit routing-options] hierarchy on router1.

You must specify type as external on both devices.

You must specify the local-address on both devices.

Correct Answer: A

To establish the BGP session between router1 and router2, you must define the peer-as number on router2. The configuration on router1 specifies the peer-as number as 65512, but this is not mirrored on router2. Both routers need to have matching BGP configurations that include the peer-as numbers for the session to establish correctly.

Question 5 of 35

Which router ID is correct for OSFPv3?

0.0.0.0

2001:123:6::1

::172.16.1.1

172.16.1.1

Correct Answer: D

For OSPFv3, which is the version of OSPF for IPv6, the router ID must still be expressed in the format of an IPv4 address. Therefore, 172.16.1.1 is the correct format for an OSPFv3 router ID. The options 0.0.0.0, 2001:123:6::1, and ::172.16.1.1 are either invalid or incorrectly formatted for this purpose.
