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

Topic 1
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.)

Topic 1
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?
C
Topic 1

in the EPG server?
A
Topic 1

Topic 1
DRAG DROP
A leaf receives unicast traffic that is destined to an unknown source, and spine proxy is enabled in the corresponding bridge
domain. Drag and drop the Cisco ACI forwarding operations from the left into the order the operation occurs on the right.

Topic 1
An engineer deployed a Cisco ACI fabric and noticed that the fabric learns endpoints from subnets that are not configured on
a bridge domain. To meet strict security requirements, the engineer must prevent this behavior. Which action must be taken
to prevent this behavior?
D
Topic 1
Refer to the exhibit. An engineer is configuring a vSwitch policy in the existing Cisco ACI fabric. The requirement is for the
Cisco ACI leaf to learn individual MAC addresses from the same physical port. Which vSwitch policy configuration mode
must be enabled to meet this requirement?
A
Topic 1
A host that is connected to a Cisco ACI fabric leaf switch sends an ARP request. Which transmission method does the
ingress switch use to send the ARP requests?
D

Topic 1
An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was
investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch
ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it
was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?
B
Topic 1
An engineer implements the Cisco ACI solution and needs to confirm that the leaf switch correctly learns the remote
endpoint MAC. Which information must be included in the VXLAN packet that is received from the Cisco ACI spine for the
Cisco ACI leaf to learn MAC as a remote endpoint?
C
