You want to ensure that your all-Junos MPLS core network does not decrease the TTL when using ping and traceroute from IP endpoints. Which two configuration parameters satisfy this requirement? (Choose two.)

A no-decrement-ttl, configured on all routers in the path
B no-decrement-ttl, configured on the ingress router only
C no-propagate-ttl, configured on all routers in the path
D no-propagate-ttl, configured on the ingress router only

You have configured an MPLS LSP that includes defined hops. For this path, you want the MPLS label to be popped at the egress node.
Which configuration statement meets this requirement?

A Set protocols rsvp explicit-null, configured on the ingress node
B Set protocols mpls explicit-null, configured on the egress node
C Set protocols mpls explicit-null, configured on the ingress node
D Set protocols rsvp implicit-null, configured on the egress node

You are asked to provide Layer 3 VPN services to a new customer site. The site will connect to the Layer 3 VPN using a Layer 2 switch. Which two configuration elements meet the requirement? (Choose two.)

A vrf-table-label
B vt interface
C vrf-target
D vrf-export

Refer to the exhibit.

Question Image

You are implementing a Layer 3 VPN between Site 1 and Site 2. You notice that you are not sharing routes between PE1 and PE2. You have verified that MPLS and RSVP are functioning correctly. Referring to the exhibit, what is causing the problem?

A The multihop feature is not enabled.
B The next hop for the VPN routes is unusable.
C The Layer 3 VPN NLRI has not been enabled on PE1.
D The PE2 BGP session is restarting.

You are deploying a next-generation multicast VPN in your network and must identify which routers require tunnel services?

A DRs closest to the receiver require tunnel services.
B DRs closest to the source require tunnel services.
C All MVPN PE routers require tunnel services.
D All MVPN P routers require tunnel services.

You want to copy only OSPF prefixes from site.inet.0 to company.inet.0.

Question Image

What is the proper configuration syntax you must use to accomplish this task?

Question Image

A Option A
B Option B
C Option C
D Option D

Refer to the exhibit.

Question Image

You have the Layer 2 VPN configuration shown in the exhibit. You have been asked to determine the remote site ID for ge-1/0/4.512. What is the remote site ID?

A 1
B 3
C 4
D unspecified

You are asked to provision a BGP-signaled Layer 2 VPN for a new customer.
What information is required for the VPN routing instance that is connected to the CE device?
(Choose three.)

A the logical interfaces provisioned to the local CE device
B the logical interfaces provisioned to the remote PE device
C the Layer 2 encapsulation type
D the local site ID
E the circuit identifier

You are configuring a Layer 2 circuit. Which two configuration steps are required? (Choose two.)

A Configure LDP on the interfaces between PE and CE routers.
B Configure circuit or translational cross-connects between PE routers and between PE and P routers.
C Configure circuit or translational cross-connects between PE and CE routers.
D Configure LDP on the interfaces between PE routers and between PE and P routers.

You are asked to implement an LDP-signaled VPLS network for a new customer. Which two statements are correct regarding this implementation? (Choose two.)

A A full mesh of LDP sessions between PEs must be configured.
B The PE routers distribute VPLS to label mapping using MP-IBGP.
C The same NLRI as Layer 2 VPNs is used.
D The PE router advertises a label for each remote PE configured.

You are asked to deploy VPLS in your network as a new service for several customers and must identify the configuration and provisioning requirements. Which two statements are correct? (Choose two.)

A PE routers must include a VRF routing instance.
B PE interfaces facing customers must have family VPLS configured.
C PE routers must create a unique site ID for each CE device.
D CE routers must be configured with their assigned route target.

Refer to the exhibit.

Question Image

In a newly configured VPLS network, you see the output shown in the exhibit. The remote PE is 10.1.1.2. What is the cause for the OL status?

A There is not a proper label-switched path to the remote PE, so there is no MPLS path to the remote PE.
B The VPLS site identifiers are not contiguous, causing label block allocation to run out of labels.
C The MPLS protocol family is not configured for interface fe-0/1/2.2, so the LDP adjacency is in an error state.
D The remote PE is using the wrong route distinguisher, so the outgoing labels are incorrect.

Which configuration parameter would be used by a commit script to use custom syntax and simplify the configuration?

A Apply-groups
B Allow-transients
C Direct-access
D Apply-macro

Which two statements regarding OSPFv2 or OSPFv3 authentication are correct? (Choose two.)

A OSPFv2 supports MD5 authentication.
B OSPFv2 supports MD5 or SHA authentication.
C OSPFv2 relies on the native security stack that uses IPsec.
D OSPFv3 relies on the native security stack that uses IPsec.

Refer to exhibit.

Question Image

Referring to the script and configuration shown in the exhibit, what would be the output after committing the configuration?

Question Image

A Option A
B Option B
C Option C
D Option D
