• Question 14:

  Which component provides Cisco ACI fabric with Layer 2 and Layer 3 connectivity across pods and physical locations?

  A. Inter-Pod Network
  B. VXLAN overlay
  C. COOP control plane
  D. Cisco APIC control cluster

• Question 15:

  An engineer must configure Cisco ACI for VMM integration to VMware vCenter. Which two attributes must be configured on the Cisco APIC to achieve this goal? (Choose two.)

  A. cluster name
  B. virtual switch name
  C. data center name
  D. port group
  E. logon credentials
  B. virtual switch name
  E. logon credentials

  Explanation/Reference:

  Data Center name is specified in Create vCenter Controller screen

• Question 16:

  A customer creates Layer 3 connectivity to the outside network. However, only border leaf switches start receiving destination updates to other networks from the newly created L3Out. The updates must also be propagated to other Cisco ACI leaf switches. The L3Out is linked with the EPGs via a contract. Which action must be taken in the pod policy group to accomplish this goal?

  A. Apply a BGP route reflector policy.
  B. Enable a COOP policy.
  C. Configure an IS-IS policy.
  D. Implement an access management policy.
  A. Apply a BGP route reflector policy.

• Question 17:

  A network engineer implements an L3Out inside the Cisco ACI fabric. The engineer plans to connect a Cisco ACI leaf switch to a switch outside of the Cisco ACI fabric to exchange routes via a routing protocol. The external switch interface is configured with IP address 192.168.15.1/30. The ACI engineer wants to use a routing protocol that uses a hierarchical network design. The Cisco ACI fabric should use the L3Out to access the Internet. Which set of steps must be taken to meet these requirements?

  A. Set up the BGP Protocol policy with the appropriate Autonomous System number. Create the Routed Outside object and Node profile, selecting BGP as the routing protocol. Build the Interface profile, selecting SVI and the appropriate VPC. Configure the 0.0.0.0/32 network as part of the External Network object.
  B. Set up the EIGRP Protocol policy with the selected Autonomous System number. Set up the Routed External Network object and Node profile, selecting EIGRP. Create the Switch profile, selecting VPC and the appropriate interfaces. Create the default network and associate it with the Routed Outside object.
  C. Set up the EIGRP Protocol policy with the selected Autonomous System number. Configure an Interface policy and an External Bridged Domain. Create an External Bridged Network using the configured VLAN pool. Build the Leaf profile, selecting Routed Sub-Interface and the appropriate VLAN.
  D. Configure the OSPF Protocol policy with an area of 0. Create the Routed Outside object and Node profile, selecting OSPF as the routing protocol. Build the Interface profiles, selecting Routed Interface and the appropriate interface. Set up the External Network object with a network of 0.0.0.0/0.
  D. Configure the OSPF Protocol policy with an area of 0. Create the Routed Outside object and Node profile, selecting OSPF as the routing protocol. Build the Interface profiles, selecting Routed Interface and the appropriate interface. Set up the External Network object with a network of 0.0.0.0/0.

  C. Export the contract and import as a contract interface.
  D. Change the contract scope to Tenant.
  E. Change the subject scope to VRF.
  A. Set the subnet scope to Shared Between VRFs.
  D. Change the contract scope to Tenant.

  B. It downloads firmware image on leaf switches.
  C. It pushes policy elements from Cisco APIC to leaf switches.
  D. It assigns VTEP IPs to leaf switches.
  B. It downloads firmware image on leaf switches.

• Question 20:

  Refer to the exhibit.

  

  An application called App_1 is hosted on the server called S1. A silent host application, App_2, is hosted on S2. Both applications use the same VLAN encapsulation.

  Which action forces Cisco ACI fabric to learn App_2 on ACI leaf 2?

  A. Set Unicast Routing to Hardware Proxy.
  B. Set L2 Unknown Unicast to Flood.
  C. Set L3 Unknown Multicast to Optimized flood.
  D. Set Multi-Destination Flooding to Drop.
  B. Set L2 Unknown Unicast to Flood.
