What should be done with the license key after it has been entered in the vCenter License Service?

After entering the license key in the vCenter License Service, the key should be assigned to the vCenter Server instance to enable its features and functionalities. This assignment is essential as it ties the license key to the specific instance of the vCenter Server, allowing it to operate under the provisions of the licensed version.

Assigning the license ensures compliance with VMware's licensing agreements and facilitates the management of resources within the vSphere environment. It also allows administrators to take advantage of the specific tools and capabilities that the license unlocks, such as advanced management features, resource allocation, and monitoring tools.

Documentation of the license key for future reference can be a good practice, but it is not the immediate action required after entry. Discarding the license key or sending it to VMware support does not apply, as these actions do not fulfill the necessary steps for proper license management within the vCenter Server environment.
