N-VDS/VDS Statements

CD.

N-VDS (Network Virtualization Distributed Switch) and VDS (Virtual Distributed Switch) are both software-based switches used in VMware environments. Here are the explanations for the given statements:

A. KVM hosts support both N-VDS and VDS: This statement is not entirely accurate. KVM hosts are not part of the VMware environment and do not support N-VDS or VDS. KVM is a hypervisor used in Linux environments and uses the Linux bridge for networking. Therefore, this statement is false.

B. It is a module deployed in all transport nodes that provides L2 functionality: This statement is partially true. N-VDS and VDS are both virtual switches that provide Layer 2 (L2) functionality in VMware environments. They are deployed on transport nodes, which are ESXi hosts or bare-metal servers that provide network connectivity to virtual machines. However, VDS is now considered legacy and has been replaced by N-VDS in modern VMware environments.

C. It is a module deployed in all transport nodes that provides L3 functionality: This statement is false. N-VDS and VDS both provide Layer 2 (L2) functionality and do not provide Layer 3 (L3) functionality. Layer 3 functionality is provided by the NSX-T Edge, which is a virtual machine that provides routing, firewall, and other network services in VMware environments.

D. ESXi hosts support both N-VDS and VDS: This statement is true. ESXi hosts are part of the VMware environment and support both N-VDS and VDS. However, as mentioned earlier, VDS is considered legacy and has been replaced by N-VDS in modern VMware environments.

E. Bare-metal servers support both N-VDS and VDS: This statement is true. Bare-metal servers are physical servers that are not virtualized and can be used as transport nodes in VMware environments. They support both N-VDS and VDS.
