- A . Upgrade
- B . Kick-off
- C . Planning
- D . Executing and Controlling
Correct Answer: D
D
Explanation:
During the Executing and Controlling phase of the RCM (Release Certification Matrix) Upgrade process, the customer is required to maintain configuration lock.

Question #37
Which NSX component communicates with the VTEP?
- A . NSX Edge
- B . NSX Controller
- C . NSX Manager
- D . Logical Router Control VM
Correct Answer: B
B
Explanation:
Identify the VTEP’s role: The VTEP, or VXLAN Tunnel Endpoint, is responsible for encapsulating and de-encapsulating the network traffic sent over the VXLAN1.
Understand NSX Components: The NSX Controller is a key component of the VMware NSX network virtualization platform. It is responsible for the control plane, managing the state of virtual networks and overlay transport zones1.
Communication with VTEP: The NSX Controller communicates with the VTEP to manage the overlay network and ensure that traffic is correctly routed and encapsulated across the network infrastructure1.
Role of other NSX Components: While the NSX Edge provides routing services and the NSX Manager is the centralized management component, it is the NSX Controller that directly manages the state of the virtual network and communicates with the VTEPs1.
