Accepted Answer

A. two clusters; scratch The `clusters` array explicitly lists two entries: `development` and `scratch`. The `users` section defines the `developer` user with `client-certificate` and `client-key`, and this user is associated with the `development` cluster. The `experimenter` user, which accesses the `scratch` cluster, has no certificate details specified in the provided `users` block, implying it uses an alternative authentication method like username/password.

Answer

B. three clusters; scratch The YAML exhibit clearly defines only two distinct cluster objects under the `clusters` key, not three.

Answer

C. Three clusters; development The YAML exhibit clearly defines only two distinct cluster objects, not three. Additionally, the `development` cluster is explicitly shown to be accessed via `client-certificate` authentication, not username/password.

Answer

D. Two clusters; development While there are two clusters defined, the `development` cluster is accessed using certificate-based authentication as defined for the `developer` user.
