2V0-41.24 Question 41
Select 3An organization is designing a network virtualization solution using VMware NSX. The design team wants to ensure that virtual machines across different clusters can communicate over the overlay network. Which combination of components is required to configure this functionality?
- A
Transport zones to define the scope of the overlay networks
- B
Transport nodes to enable NSX-T Data Plane functionality on ESXi hosts
- C
Virtual Distributed Switch (VDS) to create logical switches for overlay networks
- D
N-VDS (NSX Virtual Distributed Switch) to handle overlay traffic
- E
Transport zones to connect physical network switches to NSX
Show answer and explanation
Correct answers: A, B, D
Explanation
To enable communication between virtual machines across different clusters in an NSX environment, transport zones are required to define the scope of overlay networks, transport nodes are needed to provide NSX Data Plane functionality on the ESXi hosts, and N-VDS (or VDS with NSX capabilities) is used to manage overlay traffic. These components work together to establish connectivity and ensure proper functionality of the NSX overlay network.
- A. Correct.
Transport zones define the scope of NSX overlay networks, determining which transport nodes can participate. This is essential for cross-cluster communication.
- B. Correct.
Transport nodes enable NSX-T Data Plane functionality on ESXi hosts, allowing them to communicate over the overlay network.
- C. Incorrect.
VDS is part of vSphere networking and is not specifically designed to handle NSX overlay networks. NSX uses N-VDS or VDS with enhanced capabilities for this purpose.
- D. Correct.
N-VDS (or VDS with NSX support in NSX-T 3.x and later) is used to manage network traffic, including overlay traffic in an NSX deployment.
- E. Incorrect.
Transport zones do not connect physical network switches to NSX. Instead, they define the scope of overlay or VLAN-backed networks in NSX.
