Questions 3

Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.

Which action would solve this problem?

Options:

A.  

Configure the links between the access switches and the distribution switch as a trunk port.

B.  

Disable the BPDU block function on the access switches.

C.  

Disable the BPDU block function on the distribution switch.

D.  

Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.

Options:

A.  

VLAN to instance mapping

B.

D.  

bridge priority

E.  

region name

Questions 5

Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.

In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

Options:

A.  

Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.

B.  

Configure an MSDP protocol between R2 and R3.

C.  

Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.

D.  

Configure an MSDP protocol between R1 and R2.

Questions 6

You must provide network connectivity to hosts that fail authentication.

In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

Options:

A.  

Configure the native-vlan-id parameter on the port.

B.  

Use the server-reject-vlan command to specify a guest VLAN.

C.  

Configure a secondary IP address on the port for unauthenticated hosts.

D.  

Configure the port as a spanning tree edge port.

Questions 7

You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.

Which two steps would you take to further troubleshoot this problem? (Choose two.)

Options:

A.  

Verify that the same ESI is configured on the link from the host and that it matches the source.

B.  

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.

C.  

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.

D.  

Verify that the same ESI is configured on the two links from the source.

Questions 8

A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.

In this scenario, what would solve this problem?

Options:

A.  

Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.

B.  

Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.

C.  

Adjust the scheduler-map to support a higher transmit rate.

D.  

Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.
