Demo Questions

Question 1
Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?

  • A: Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
  • B: POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
  • C: Leaf 101 encapsulates the ARP request into a multicast packet that is destined to
  • D: Leaf 101 switch consumers the ARP reply of VM2 to update the local endpoint table.

Question 2
Which approach does Cisco ACI use to achieve multidestination packet forwarding between leaf switches in the same fabric?

  • A: Map VXLAN VTEP to the multicast group
  • B: Map VXLAN to PIM-SM protocol
  • C: Map VXLAN VNI to the multicast group
  • D: Map VXLAN to PIM-DM protocol

Question 3
What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?

  • A: ECMP
  • B: TCP optimization
  • C: disabled fragmentation
  • D: jumbo frames

Question 4
Which two actions are the Cisco best practices to configure NIC teaming load balancing for Cisco UCS B-Series blades that are connected to the Cisco ACI leaf switches? (Choose two.)

  • A: Create vPC+
  • B: Enable LACP active mode
  • C: Create PAgP
  • D: Create vPC
  • E: Enable MAC pinning

Question 5
An organization migrates its virtualized servers from a legacy environment to Cisco ACI. VM1 is incorrectly attached to PortGroup IT|3TierApp|Web. 
Which action limits IP address learning in BD1?

  • A: Enable Enforce Subnet Check 
  • B: Enable Rouge Endpoint Control
  • C: Enable GARP-based EP Move Detection Mode
  • D: Disable Remote EP Learn

Question 6

Refer to the exhibit. What must be configured to allow the PBR node (LB-int) to monitor the availability of the endpoint that is in the EPG server?

  • A: Endpoint Dataplane Learning
  • B: Unicast Route disabled for client and server bridge domains
  • C: PBR node tracking
  • D: Direct Connect in the service graph template

Question 7
An engineer must limit local and remote endpoint learning to the bridge domain subnet. Which action should be taken inside the Cisco APIC?

  • A: Disable Remote EP Learn
  • B: Enable Enforce Subnet Check
  • C: Disable Endpoint Dataplane Learning
  • D: Enable Limit IP Learning to Subnet 

Question 8
What is the purpose of the Forwarding Tag (FTAG) in Cisco ACI?

  • A: FTAG is used in Cisco ACI to add a label to the iVXLAN traffic in the fabric to apply the correct policy.
  • B: FTAG is used in Cisco ACI to add a label to the VXLAN traffic in the fabric to apply the correct policy.
  • C: FTAG trees in Cisco ACI are used to load balance unicast traffic.
  • D: FTAG trees in Cisco ACI are used to load balance mutli-destination traffic.

Question 9
Refer to the exhibit. Which three actions should be taken to implement the vPC in the Cisco ACI fabric? (Choose three.)

  • A: Select a common vPC interface policy group
  • B: Select individual interface profiles 
  • C: Select common interface profiles
  • D: Select individual switch profiles
  • E: Select common switch profiles

Question 10
Which action should be taken in Cisco ACI to reassign a unique globally scoped pcTag to an EPG that provides a global contract?

  • A: Configure subnets that are treated as virtual IP
  • B: Configure subnets that advertise externally
  • C: Configure subnets that are shared between VRFs
  • D: Configure subnets that are private to VRF
