Question 1 of 60
Exam 600-660: Question 1 - Image 1
Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?
Answer

Suggested Answer

The suggested answer is C.

In the exhibit, ARP flooding is disabled, and the option for IP data-plane learning is enabled with the 'Limit IP Learning to Subnet' option also checked. These settings suggest that multicast-based forwarding is used for unknown unicast and ARP traffic. Therefore, if VM2 is not learned in the Cisco ACI fabric, Leaf 101 would encapsulate the ARP request into a multicast packet destined to 225.0.37.192 for efficient distribution across the network.

Question 2 of 60
Which approach does Cisco ACI use to achieve multidestination packet forwarding between leaf switches in the same fabric?
Answer

Suggested Answer

The suggested answer is C.

Cisco ACI maps VXLAN VNIs (Virtual Network Identifiers) to multicast groups for efficient forwarding of multidestination traffic between leaf switches in the same fabric. This approach allows the network to handle multicast, broadcast, and unknown unicast traffic effectively by using the multicast group to distribute these types of packets across the relevant switches.

Question 3 of 60
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?
Answer

Suggested Answer

The suggested answer is A.

Question 4 of 60
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.)
Answer

Suggested Answer

The suggested answer is B, E.

Question 5 of 60
Exam 600-660: Question 5 - Image 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?
Answer

Suggested Answer

The suggested answer is A.

To limit IP address learning in BD1, the appropriate action to take is to enable Enforce Subnet Check. This setting ensures that only IP addresses within the defined subnet are learned, preventing the learning of any IP addresses that do not belong to the specified subnet, thus maintaining the security and integrity of the network.
