An administrator wants to ensure that user VMs on AHV hosts can take advantage of bandwidth beyond a single adapter in a bond. Which uplink Bond Type should the administrator configure to accomplish this?

The Active-Active bond type in Nutanix AHV is designed to increase throughput and provide load balancing by distributing network traffic across all active physical adapters in the bond. This configuration allows the collective traffic from virtual machines on the host to exceed the bandwidth of a single network adapter. The Active-Active type includes two specific load-balancing algorithms: balance-slb and balance-tcp (LACP), both of which utilize multiple uplinks simultaneously to achieve higher aggregate bandwidth and fault tolerance.

A. No Uplink Bond: This option means no bonding is used. VM traffic would be limited to the capacity of a single, un-bonded physical adapter.
C. Active-Active with MAC pinning: This describes a specific load-balancing mode (balance-slb) within the Active-Active type. While it does use multiple uplinks, "Active-Active" is the broader and more accurate bond type category.
D. Active-Backup: This bond type provides only fault tolerance. Only one adapter is active at any time, while the others are in a passive standby state, offering no bandwidth aggregation.

1. Nutanix AHV Administration Guide (AOS 6.5): In the "Host Network Management" section, under "Load Balancing in a Bond," it states, "To use the bandwidth of more than one link, you must use a load balancing algorithm... AHV supports the following active-active load balancing algorithms: Balance-SLB... Balance-TCP." This confirms that an active-active configuration is required.

2. Nutanix University - NCP-MCI 6.5 Study Guide: Section 2.3, "Configure AHV Host Networking," describes the bond modes. It clarifies that Active-Active modes are used for load balancing and increased throughput, contrasting with Active-Backup, which is for redundancy only.

3. Prism Web Console Guide (AOS 6.5): In the "Network Configuration" section, when creating or updating a virtual switch, the primary bonding choices presented in the UI are "Active-Backup" and "Active-Active," establishing "Active-Active" as the correct bond type category for load balancing.
