  A. 1. Create a contract with a filter matching "IP" only 2. Create a L4-L7 device, function type "GoTo" 3. Create a L4-L7 Policy-Based Redirect Policy with the L3 Destination set to the load-balancer inside IP/MAC 4. Create a service graph template that references the previously created contract and L4-L7 device 5. Apply the service graph template. Select "L3 Destination" and reference L4-L7 Policy-Based Redirect Policy on the provider connector only
  B. 1. Create a contract linked to the common/default filter 2. Create a L4-L7 device, function type "GoThrough" 3. Create a L4-L7 Policy-Based Redirect Policy with the L3 Destination set to the load-balancer inside IP/MAC 4. Create a service graph template that references the previously created contract and L4-L7 device 5. Apply the service graph template. Select "L3 Destination" and reference L4-L7 Policy-Based Redirect Policy on the consumer and provider connector
  C. 1. Create a contract linked to the common/default filter 2. Create a L4-L7 device, function type "GoTo" 3. Create a L4-L7 Policy-Based Redirect Policy with "Anycast Endpoint" enabled and the L3 Destination set to the load-balancer inside IP/MAC 4. Create a service graph template that references the previously created contract and L4-L7 device 5. Apply the service graph template. Select "L3 Destination" and reference L4-L7 Policy-Based Redirect Policy on the consumer connector only
  D. 1. Create a contract with a filter matching "IP" only 2. Create a L4-L7 device, function type "GoThrough" 3. Create a L4-L7 Policy-Based Redirect Policy with "Anycast Endpoint" enabled and the L3 Destination set to the load-balancer inside IP/MAC 4. Create a service graph template that references the previously created contract and L4-L7 device 5. Apply the service graph template. Select "L3 Destination" and reference L4-L7 Policy-Based Redirect Policy on the consumer and provider
  A. 1. Create a contract with a filter matching "IP" only 2. Create a L4-L7 device, function type "GoTo" 3.

  B. Implement Pervasive Gateway
  C. Configure Static Binding
  D. Enable Enforce Subnet Check
  D. Enable Enforce Subnet Check

• Question 35:

  What is a use of the Overlay Multicast TEP in Cisco ACI Multi-Site communication?

  A. to perform headend replication
  B. to act as the source IP for BUM traffic
  C. to establish MP-BGP adjacencies with remote spines
  D. to send and receive unicast VXLAN data plane traffic
  B. to act as the source IP for BUM traffic
