When replacing a damaged Chromebook in the Google GSuite admin console, what license allows you to reuse a license for the same model Chromebook?

When replacing a damaged Chromebook in the Google GSuite admin console, what license allows you to reuse a license for the same model Chromebook?

• Annual
• KMS
• Perpetual
• MAK 

 

EXPLANATION

Google allows a Google GSuite console to move licenses to a different Chrome device, but there are differences. There are a Annual and Perpetual. Perpetual licenses are a one time purchase for a single type of device. If that device breaks and is replaced with the same model, you can transfer the license to that device. If you would replace it with a different type and model of device, you would have to purchase an additional license.
An annual license is bought per term and in the case of this, you can transfer the license to any new devices, regardless of the model and type during the license term.
Also, different versions of GSuite support different licensing models. GSuite Enterprise supports Annual and Perpetual, whereas GSuite Education and GSuite Nonprofit only supports Perpetual.
