300-630 Exam Dumps : Implementing Cisco Application Centric Infrastructure - Advanced (DCACIA)

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.

For shared L3Out network connectivity among different tenants in a Cisco ACI fabric, a common tenant is necessary. It provides a global space for defining resources like L3Outs once, which can then be utilized by multiple tenants, simplifying management and ensuring consistent policy application. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

The minimum MTU value that must be supported by the ISN to allow control plane endpoint information exchange between sites in a Cisco ACI Multi-Site setup with default settings is 1554 bytes (B). This accounts for the standard MTU of 1500 bytes plus additional overhead for VXLAN encapsulation. An MTU of 9000 (A) or 9100 © is not the minimum required, and 1600 (D) is not related to the default fabric settings5. References := (Multi-site / Multi-Pod MTU Jumbo Frames5)
