• Question 31:

  Click the Exhibit button.

  

  Referring to the exhibit, you have multiple Layer 3 VPNs established in your network. You are asked to ensure that PE-4 allows CE-2 in VPN 1 to communicate with CE-1 in VPN 3.

  Which two statements are correct in this scenario? (Choose two.)

  A. Use a BGP export policy to share the appropriate VRF routes.
  B. Use the auto-export feature to share the appropriate VRF routes.
  C. Use a BGP import policy to share the appropriate VRF routes.
  D. Use rib-groups to share the appropriate VRF routes.
  A. Use a BGP export policy to share the appropriate VRF routes.
  C. Use a BGP import policy to share the appropriate VRF routes.

• Question 32:

  Which two statements are correct regarding site IDs and circuit IDs in a VPLS routing instance? (Choose two.)

  A. In an LDP VPLS routing instance, vpls-id parameters must be different in each location.
  B. In an LDP VPLS routing instance, the vpls-id parameters must match in all locations.
  C. In a BGP VPLS routing instance, the site-id parameters must be different in each location.
  D. In a BGP VPLS routing instance, the site-id parameters must match in all locations.
  B. In an LDP VPLS routing instance, the vpls-id parameters must match in all locations.
  C. In a BGP VPLS routing instance, the site-id parameters must be different in each location.

• Question 33:

  You have deployed route reflectors in your network. You are receiving the route 200.0.0.0/24 from AS10 and AS6 and are seeing the oscillation happening as shown in the exhibit. What are two ways to solve this issue? (Choose two.)

  A. Configure the always-compare-med parameter on both route reflectors.
  B. Configure the add-path parameter on both route reflectors.
  C. Configure the med-plus-igp parameter on both route reflectors.
  D. Configure the as-path-ignore parameter on both route reflectors.
  A. Configure the always-compare-med parameter on both route reflectors.
  C. Configure the med-plus-igp parameter on both route reflectors.

• Question 34:

  You want to use IS-IS on a GRE interface where the underlying Layer 3 MTU is 1500.

  Which statement is correct in this scenario?

  A. IS-IS can be used because every IS-IS interface must be capable of transmitting packets at least as large as 1476 bytes, and the GRE header is 24 bytes.
  B. IS IS can be used, but the networking device directly attached to the circuit must be capable of fragmentation.
  C. IS-IS cannot be used, but the router can enable a GRE key that serves the same function as IS-IS.
  D. IS-IS cannot be used because the IS-IS hello is not allowed to be fragmented and has the DF bit set.
  B. IS IS can be used, but the networking device directly attached to the circuit must be capable of fragmentation.

• Question 35:

  Click the Exhibit button.

  

  What is accomplished by the default-gateway parameter in the configuration shown in the exhibit?

  A. The device creates a default route and distributes the IP address to all peers.
  B. The device sends the MAC and IP addresses of the IRB interface to its peers.
  C. The device sends the IP address of the IRB interface without the MAC address.
  D. The device creates a default route and distributes its MAC and IP address to all peers.
  B. The device sends the MAC and IP addresses of the IRB interface to its peers.

• Question 36:

  Click the Exhibit button.

  

  Referring to the exhibit, why are R1 and R2 not exchanging routes between their VPNs?

  A. The route targets are not property configured.
  B. The IP addresses in the BGP configuration must be in the same subnet.
  C. The interfaces unit numbers must be the same on both sides.
  D. The route distinguishers are not properly configured.
  D. The route distinguishers are not properly configured.

• Question 37:

  Which transport mechanism is required for Layer 3 VPNs?

  A. GRE
  B. VXLAN
  C. IPsec
  D. MPLS
  D. MPLS

  B. The local site is site ID 1.
  C. The route-distinguisher is in the wrong format.
  D. Interface ge-0/0/l.512 is connected to the local site
  A. Remote site 1 is dual-homed.
  B. The local site is site ID 1.

• Question 40:
