Which contract insertion method must be used to meet these requirements?

  A. Provider: each service EPGs Consumer: vzAny inside the VRF
  B. Provider: each service EPGs Consumer: L3Out external EPGs
  C. Provider: L3Out external EPGs Consumer: each service EPGs
  D. Provider: L3Out external EPGs Consumer: vzAny inside VRF
  D. Provider: L3Out external EPGs Consumer: vzAny inside VRF

• Question 23:

  

  Refer to the exhibit. An engineer must have communication between EPG1 in VRF1 and External EPG in VRF2. Which three actions should be taken for the defined subnets in the L3Out External EPG to accomplish this goal? (Choose three.)

  B. Enable External Subnets for External EPG
  C. Enable Export Route Control Subnet
  D. Enable Shared Security Import Subnet
  E. Enable Aggregate Shared Routes
  F. Enable Import Route Control Subnet
  A. Enable Shared Route Control Subnet
  B. Enable External Subnets for External EPG

  C. Implement a policy-based redirect using a service graph.
  D. Add a new stretched external EPG to the existing L3outs.
  A. Configure host route advertisement on the bridge domains.

• Question 25:

  B. Enable LACP active mode
  C. Create PAgP
  D. Create vPC
  E. Enable MAC pinning
  B. Enable LACP active mode
  E. Enable MAC pinning

• Question 27:
