Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?
When VM2 is not learned in the Cisco ACI fabric, Leaf 101 forwards the ARP request to one of the proxy VTEP spines. This is because the local leaf (Leaf 101 in this case) does not have information about VM2 and since ARP flooding is disabled, it encapsulates the ARP request toward one of the Proxy Anycast VTEP addresses available on the local spine nodes to avoid flooding along the local multi-destination tree.
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.)
To configure NIC teaming load balancing for Cisco UCS B-Series blades connected to the Cisco ACI leaf switches, it is recommended to use LACP in active mode because it provides dynamic link aggregation and can automatically configure and manage the aggregation. Additionally, creating a vPC (Virtual Port Channel) allows link redundancy and load balancing across multiple physical links while simplifying the network topology. vPC also provides benefits such as loop prevention and increased bandwidth without needing additional protocols.
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?
To limit IP address learning in BD1, the appropriate action is to enable Enforce Subnet Check. This feature ensures that only IP addresses within the subnets defined in the bridge domain are learned and allowed. In this case, enabling this feature will restrict IP address learning to the 172.16.0.0/24 subnet, which should prevent the incorrect IP address (192.168.0.10) from being learned and associated with BD1.
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?
To allow the PBR node (LB-int) to monitor the availability of the endpoint in the EPG server, it is essential to configure 'Direct Connect' in the service graph template. This setting allows for the transmission of keepalive messages from the load-balancer endpoint to the web endpoint, ensuring the PBR node can effectively monitor the endpoint's availability.
An engineer must limit local and remote endpoint learning to the bridge domain subnet. Which action should be taken inside the Cisco APIC?
To limit local and remote endpoint learning to the bridge domain subnet in the Cisco APIC, you should enable the 'Limit IP Learning to Subnet' option. This option ensures that only IP addresses within the specified subnet are learned, effectively restricting both local and remote endpoint learning to the bridge domain subnet.
