Which of the following access levels limits cluster configuration options?

The access level that limits cluster configuration options is referred to as "No Isolation Shared." This model is designed for multi-tenant environments where multiple users or groups share clusters. In this scenario, users may have restricted permissions when it comes to configuring and managing clusters to ensure that changes made by one user do not adversely affect others sharing the same computational resources.

By enforcing limitations on cluster configurations, the "No Isolation Shared" access level helps maintain stability and performance across workloads. Users can run their jobs without the risk of interfering with others, but they do not have the ability to change critical settings such as instance types, scaling, or library installations, which could lead to inconsistencies or resource issues.

Other access levels like "Shared," "Custom," or "All available options" generally provide more flexibility and various permissions related to cluster configurations, which do not impose the same level of restrictions found in the No Isolation Shared model.
