In this scenario, what is required for communication between VLANs to occur?

  A. IBGP and Q-in-Q

  B. IBGP and MP-BGP

  C. IBGP and MPLS

  D. IBGP and GVRP

  Correct Answer: B

• Question 2:

  What is a characteristic of VRRP?

  A. VRRP routers must communicate over a direct connection.

  B. VRRP participating routers all act as active gateways.

  C. VRRP provides high availability for a host's default gateway.

  D. VRRP routes must communicate over a common switch.

  Correct Answer: C

• Question 3:

  Which two statements are true in this scenario according to Juniper Networks recommendations? (Choose two.)

  A. Spine devices must assume the RE role.

  B. Leaf devices must have a direct link to all other leaf devices.

  C. Spine devices must assume the line card role.

  D. Leaf devices must have a direct link to all spine devices.

  Correct Answer: AD

• Question 4:
