Question No: 1 – (Topic 1)

What is a limitation of LDP?

  1. Traffic must follow explicitly configured paths.

  2. It requires a full mesh of LSPs throughout the network.

  3. It requires a traffic engineering database (TED).

  4. It does not support traffic engineering.

Answer: D

Question No: 2 – (Topic 1)

Which two statements correctly describe BGP operation? (Choose two.)

  1. IBGP does not advertise routes learned from other IBGP neighbors.

  2. IBGP advertises routes learned from other IBGP neighbors.

  3. EBGP advertises routes learned from other IBGP or EBGP neighbors.

  4. EBGP does not advertise routes learned from other EBGP neighbors.

Answer: A,C

You work for ISP A. Customers of both ISP B and ISP C must be able to reach all of your customers, but your network must not allow transit traffic between ISP B and ISP C.

Referring to the exhibit, which two methods could you use? (Choose two.)

  1. Use local preference to prefer the proper routes.

  2. Use the well-known no-transit community.

  3. Use policy to filter routes on AS number.

  4. Use communities to identify and filter routes.

Answer: C,D

Your IT manager asks you to describe a benefit of migrating from LDP VPLS towards BGP VPLS considering the operational network shown in the exhibit. What can you tell your manager?

  1. Using BGP signaling improves scaling, because a full mesh of transport LSPs is not needed.

  2. MAC addresses are learned through BGP instead of LDP, which improves scaling.

  3. Ingress PE replication can be reduced, because BGP VPLS supports P2MP LSPs.

  4. Configuration overhead is reduced when adding new sites or new VPNs.

Answer: D

Question No: 5 – (Topic 1)

You have configured bidirectional LSPs between R1 and R3. You notice that the LSPs are not coming up.

Ensurepass 2018 PDF and VCE

Referring to the exhibit, which statement is correct?

  1. You must disable CSPF for the LSPs.

  2. You must enable CSPF for the LSPs.

  3. You must ensure type 5 LSAs are allowed in area 1.

  4. You must ensure OSPF traffic engineering is configured.

Answer: A

Question No: 6 – (Topic 1)

Ensurepass 2018 PDF and VCE

PE-1 is not sending any routes to the CE router in the Cust routing instance. What is the reason?

  1. There is a mismatch in the target community and the route distinguisher.

  2. The vrf-import policy is only accepting direct routes.

  3. The as override parameter is causing an AS loop on the CE device.

  4. The vrf-export policy must be explicitly defined.

Answer: B

Question No: 7 – (Topic 1)

What is the purpose of the no-cspf command?

  1. to successfully signal the LSP across the network regardless of constraints

  2. to delete the CSPF database

  3. to ignore OSPF when calculating the ERO

  4. to successfully signal the LSP only if the default IGP path (or named path) meets all constraints

Answer: D

Question No: 8 – (Topic 1)

You recently added your autonomous system to an existing BGP confederation. You notice that a route that had a local preference of 100 now has a local preference of 50. Which statement explains the change?

  1. BGP path attributes such as next hop, local preference, and MED are normally restricted to a single AS but are allowed to propagate throughout the confederation#39;s AS members.

  2. The confederation has sub-ASs that require all IBGP routes to have a local preference of 50 or below.

  3. When your Junos devices joined the confederation, they lost IBGP connectivity to the route in question; the local preference reverted to 50 once the BGP peering established.

  4. The route is being shared through an EBGP peer, and the confederation is propagating the local preference from the peer.

Answer: A

Question No: 9 – (Topic 1)

Ensurepass 2018 PDF and VCE

Based on the exhibit, what do you expect to find in the configuration on R1 and R4?

  1. a policy leaking level 1 routes into level 2

  2. a policy leaking level 2 routes into level 1

  3. a policy setting the attached bit on level 2 routes

  4. a policy setting the attached bit on level 1 routes

Answer: B

Question No: 10 – (Topic 1)

IS-IS is configured to support both IPv4 and IPv6 routing. Which statement is true?

  1. Separate IPv4 and IPv6 hellos will be sent.

  2. IPv6 will have a separate link-state database.

  3. IS-IS v6 support must be enabled under protocols isis.

  4. IS-IS sends IPv6 topology information as new TLVs in existing LSPs.
