Question 71

Exhibit

You have an established LSP between your R1 and R5 devices using the configuration shown in the exhibit. You are asked to ensure that MPLS labels are used to forward traffic by all devices within the LSP.
Which action will accomplish this behavior?

A.Configure the explicit-null statement under the protocol mpls hierarchy on R1.

B.Configure the install statement under the R1_TO_R5 label switched path on R1.

C.Delete the no-espf statement under the R1_TO_R5 label switched path on R1.

D.Configure the ultimace-hop-popping statement under the R1_TO_R5 label switched path on R1.

Question 72

How does a Junos device learn about MAC addresses when II is first connected to an Ethernet LAN?

A.The device sends out a network multicast message asking for all devices and MAC addresses on the network and stores this Information in addition to the interface from which the response was received.

B.The device learns the destination MAC addresses from traffic in the network and stores this MAC address in addition to the interface from which the traffic was received.

C.The device learns the source MAC addresses from traffic in the network and stores this MAC address in addition to the interface from which the traffic was received.

D.The device sends out a network broadcast message asking tor all devices and MAC addresses on the network and stores this information In addition lo the interface from which the response was received.

Question 73

Click the Exhibit.

Referring to the exhibit, R-1 and R-2 are connected with a LAG on the ae0 interface.
However, the LAG is not operational.
Which action will solve this problem?

A.Change the system ID on one device.

B.Change one device to use LACP passive mode.

C.Set the LACP system priority to a non-zero value on one device.

D.Set the LACP system priority to a non-zero value on both devices.

Question 74

Click the Exhibit.

You are planning the addition of a new EX3400 Series device to the network (EX-3400-7) to service MSTI-1 and MSTI-2.
Referring to the exhibit, which requirement must be met on EX-3400-7 for the MSTP instances to become fully operational and resilient?

A.The MSTP revision-level must be incremented.

B.The bridge-priority must match EX-3400-5 and EX-3400-6.

C.The MSTP configuration-name must be the same.

D.The CIST must be extended to EX-3400-7.
