Cisco Exam 300-630 Topic 7 Question 56 Discussion

The best practices for configuring NIC teaming load balancing for Cisco UCS B-Series blades connected to Cisco ACI leaf switches involve enabling LACP (Link Aggregation Control Protocol) in active mode and enabling MAC pinning.

LACP active mode (option B) allows for the automatic bundling of several physical links into a single logical link, providing redundancy and increased bandwidth. This mode actively tests the link to ensure its functionality, which is essential for maintaining a stable connection.

MAC pinning (option E) is a method that assigns a virtual machine's MAC address to a specific uplink. This ensures consistent forwarding paths for traffic within the same session, which is crucial for avoiding potential traffic distribution issues that could arise from dynamic changes in the network topology.

Creating vPC+ (option A) and vPC (option D) are not recommended as they are related to virtual port channels, which are not applicable in this scenario. PAgP (Port Aggregation Protocol) (option C) is Cisco's proprietary protocol similar to LACP, but it is not the recommended practice in this context.
