Question

A cloud design contains multiple hosts that are running a hypervisor. Each host has only two physical 10 Gb network adapters. The hosts reside in different subnets but can communicate with each other. Each host will support numerous virtual machines and network segments. What is needed to support a network segmentation in the current configuration?

Options

AIDS
BNVGRE
CMLAG
DVLAN

Explanation

NVGRE (Network Virtualization using Generic Routing Encapsulation) is a network virtualization technology that attempts to alleviate the scalability problems associated with large cloud computing deployments. It uses Generic Routing Encapsulation (GRE) to tunnel layer 2 packets over layer 3 networks. Not C: MLAG is the ability of two and sometimes more switches to act like a single switch when forming link bundles. This allows a host to uplink to two switches for physical diversity, while still only having a single bundle interface to manage. https://en.wikipedia.org/wiki/Network_Virtualization_using_Generic_Routing_Encapsulation
