Question 1

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

Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
Leaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
Leaf 101 switch consumers the ARP reply of VM2 to update the local endpoint table.

Correct answer: A

Question 2

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

Map VXLAN VTEP to the multicast group
Map VXLAN to PIM-SM protocol
Map VXLAN VNI to the multicast group
Map VXLAN to PIM-DM protocol

Correct answer: C

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?

ECMP
TCP optimization
disabled fragmentation
jumbo frames

Correct answer: A

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.)

Create vPC+
Enable LACP active mode
Create PAgP
Create vPC
Enable MAC pinning

Correct answer: BE

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?

Enable Enforce Subnet Check
Enable Rouge Endpoint Control
Enable GARP-based EP Move Detection Mode
Disable Remote EP Learn

Correct answer: C

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?

Endpoint Dataplane Learning
Unicast Route disabled for client and server bridge domains
PBR node tracking
Direct Connect in the service graph template

Correct answer: A

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?

Disable Remote EP Learn
Enable Enforce Subnet Check
Disable Endpoint Dataplane Learning
Enable Limit IP Learning to Subnet

Correct answer: B

Question 8

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

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

Correct answer: D

Question 9

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

Select a common vPC interface policy group
Select individual interface profiles
Select common interface profiles
Select individual switch profiles
Select common switch profiles

Correct answer: ABE

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?

Configure subnets that are treated as virtual IP
Configure subnets that advertise externally
Configure subnets that are shared between VRFs
Configure subnets that are private to VRF

Correct answer: C
