Which of the following is a method for apportioning resources that involves setting maximum usage amounts for all tenants/customers within the environment?

Reservations allocate a guaranteed amount of resources to a tenant or customer, ensuring availability, but do not primarily focus on setting a maximum usage amount.

Shares allocate a proportional amount of resources based on a defined ratio when resources are contested, rather than setting a strict maximum usage limit.

Cancellations refer to the termination of a service or resource allocation, not a method for initially apportioning or setting maximum usage amounts for resources.

Limits are a method of resource apportionment where administrators set maximum usage amounts for specific resources or overall consumption for tenants or customers, preventing any single entity from consuming excessive resources and ensuring fair distribution. This helps in capacity planning and preventing resource exhaustion for other users.
