To enable security and disable guest access using the Portworx Operator, the StorageCluster custom resource must be modified. The spec.security.enabled field must be set to the boolean value true. To control guest access, the spec.security.auth.guestAccess field must be set to the boolean value false. This configuration explicitly activates Portworx security features and ensures that only authenticated users can access the storage cluster, aligning with security best practices.

A: The guestAccess field requires a boolean value (true or false), not a string like 'Disabled'. This would result in a configuration error.

B: The security field is an object that contains multiple configuration keys. Assigning it a single string value like 'Enabled' is an invalid structure for the StorageCluster spec.

1. Portworx Enterprise Documentation: Enable Portworx Security with the Operator. This document details the StorageCluster spec for enabling security. It explicitly shows the required structure:

yaml

spec:

security:

enabled: true

This confirms the first part of the correct answer.

2. Portworx Enterprise Documentation: Secure -> Authentication -> Configure guest access. This section specifies how to manage guest access for authenticated clusters. It states

"To disable guest access

set the guestAccess field to false in the auth section of your StorageCluster spec":

yaml

spec:

security:

enabled: true

auth:

guestAccess: false

This directly validates that option C is the correct and complete configuration.
