  D. Delete the protocols isis ignore-attached-bit configuration statement on R3.
  A. Delete the protocols isis ignore-attached-bit configuration statement on R1.

• Question 3:

  

  You must configure an OSPF virtual link to facilitate communication between Area 0 and Area 20.

  Referring to the exhibit, which two addresses should you use as the neighbor IDs of the virtual link endpoints? (Choose two.)

  A. The address that is associated with R4's xe-0/0/1 interface.
  B. The address that is associated with R2's router ID.
  C. The address that is associated with R2's xe-1/2/0 interface.
  D. The address that is associated with R4's router ID.
  B. The address that is associated with R2's router ID.
  D. The address that is associated with R4's router ID.

• Question 4:

  

  CE-1, CE-2, and CE-3 are part of a single VPLS VPN. An Ethernet frame has just arrived at PE-3 from CE-3. It has a source MAC address of CE-3 and a destination MAC address of CE-1. You want to know what PE-3 does with the Ethernet frame.

  Referring to the exhibit, which statement is correct?

  A. It drops the packet because the destination MAC address is not in PE-3's MAC table.
  B. It forwards the packet to PE-1 and PE-2.
  C. It forwards the packet to PE-1 only.
  D. It drops the packet because the destination MAC address is not for PE-3.
  B. It forwards the packet to PE-1 and PE-2.

• Question 5:

  

  Referring to the exhibit, external routes are being received at R1. These routes must appear on R5. Which action will produce this result?

  A. Write an export policy on R4 from level 2 to level 1 matching the external routes.
  B. Turn on wide metrics on R1 and R2 and write an export policy on R4 from level 2 to level 1 matching the external routes.
  C. Write an export policy on R2 from level 1 to level 2 matching the external routes.
  D. Turn on wide metrics on R4 and R5 and write an export policy on R2 from level 1 to level 2 matching the external routes.
  B. Turn on wide metrics on R1 and R2 and write an export policy on R4 from level 2 to level 1 matching the external routes.

• Question 6:

  

  A network administrator is concerned about the number of LSAs that they are observing on the network. What will reduce Type 7 LSAs advertised from R2 to the non-backbone routers shown in the exhibit?

  A. Configure no-summaries under area 0.0.0.2 on R2.
  B. Configure nssa under area 0.0.0.2 on R2.
  C. Configure no-nssa-abr under protocols ospf3 on R2.
  D. Configure no-summaries under protocols ospf3 on R2.
  C. Configure no-nssa-abr under protocols ospf3 on R2.

• Question 7:

  Which statement is correct about BGP FlowSpec between a service provider's PE router and a customer?

  A. The flow routes received from a customer are limited to /32 masks for IPv4.
  B. The NLRI received from a customer is stored in the flowspec.inet.0 table.
  C. The RFC deterministic traffic filtering algorithm is used by default in Junos.
  D. The NLRI received from a customer is stored in the inetflow.0 table.
  D. The NLRI received from a customer is stored in the inetflow.0 table.

• Question 8:

  

  Referring to the exhibit, you have recently established a Layer 3 VPN between PE-1 and PE-2, connecting the two CE sites. Routing information is being shared between sites and the customer has two-way communication. After adding this VPN to your core network, PE-1 and PE-2 are no longer able to forward traffic to the Internet.

  In this scenario, what is the problem?

  A. You must configure the inet-vpn NLRI for the BGP sessions on both your PE devices.
  B. You must configure a multihop external BGP session between your PE devices and the Internet provider's ISP-A device
  C. You must configure the inet unicast NLRI for the BGP session on both your PE devices.
  D. You must configure a separate internal BGP group on both your PE devices specifically for Internet connectivity.
  C. You must configure the inet unicast NLRI for the BGP session on both your PE devices.

• Question 9:

  You are responsible for configuring CoS for your network Your network includes a video application with strict latency requirements, so that any packets delayed by more than 75 ms are effectively useless. You want to ensure that you do not waste buffer space.

  When configuring the scheduler for this application, which feature would you use?

  A. remainder
  B. exact
  C. temporal
  D. rate limit
  C. temporal

• Question 10:

  

  Referring to the exhibit, you are asked to summarize all routes in the 10.10.0.0/22 address range ensuring that a single summary route is present in area 49.0002 while the IS-IS internal contributing routes are restricted to area 49.0001. All other routes must not be affected.

  Which two operations would have to be performed on R2 to accomplish this task? (Choose two.)

  A. Create and apply a policy with a single term to accept only the summary route.
  B. Include the to level 2 match criteria when referencing the summary route.
  C. Include the from level 1 match criteria when referencing the summary route.
  D. Create and apply a policy with two terms; one to accept the summary route and one to reject the contributing routes.
  B. Include the to level 2 match criteria when referencing the summary route.
  D. Create and apply a policy with two terms; one to accept the summary route and one to reject the contributing routes.
