Which two options are advantages of VMware AVS instead of a VMware vDS? (Choose two )

The correct answer is B. AVS supports VLAN D. AVS supports VXLAN. VMware AVS (Application Virtual Switch) offers advantages over a standard vDS (vSphere Distributed Switch) by natively supporting both VLAN and VXLAN encapsulations for virtual machine networking within the Cisco ACI fabric.

Why each option

VMware AVS (Application Virtual Switch) offers advantages over a standard vDS (vSphere Distributed Switch) by natively supporting both VLAN and VXLAN encapsulations for virtual machine networking within the Cisco ACI fabric.

AAVS supports vPath

While vPath was a technology related to service insertion, it is not a primary advantage of AVS over vDS, and its direct support by AVS as a differentiator against vDS in this context is not accurate.

BAVS supports VLANCorrect

VMware AVS supports traditional VLAN encapsulation, allowing virtual machines connected to AVS to communicate using VLAN-backed networks within the ACI fabric.

CAVS provides a single point of management for networking

Both vDS and AVS integrate with vCenter for management, but AVS is managed by Cisco APIC, which provides a single point of management for physical and virtual networking within the ACI fabric, not necessarily for all networking compared to vDS's vCenter integration.

DAVS supports VXLANCorrect

VMware AVS natively supports VXLAN encapsulation, enabling virtual machine traffic to be extended across the ACI fabric using VXLAN tunnels, which is crucial for scalable multi-tenant environments.

EAVS supports micro segmentation

Microsegmentation in an ACI context is provided by the ACI fabric itself through EPGs and contracts, not inherently a direct feature of AVS that differentiates it from vDS as both can be endpoints for microsegmentation policies.
