NEW QUESTION # 82
A customer must restrict the share content visibility of a Dell Unity file system based on the access rights.
What attribute at the share level must be used?
- A. Protocol encryption
- B. Access-based enumeration
- C. Continuous availability
- D. Offline availability
Answer: B
Explanation:
Explanation
Access-based enumeration is the attribute that must be used at the share level to restrict the share content visibility of a Dell Unity file system based on the access rights. Access-based Enumeration (ABE) is a feature that allows you to hide files and folders from users who do not have the necessary permissions to access them.
When ABE is enabled, users only see the files and folders that they have permission to access. This helps to prevent users from accidentally accessing data that they should not have access to, and it helps to maintain the security and integrity of the data on the file system.

NEW QUESTION # 90
A customer has a fully scaled-out Dell PowerStore T cluster and wants to ensure that PowerStore Manager is in a highly available configuration How many instances of PowerStore Manager should be installed, and why?
- A. Eight A customer should install one instance per node in the cluster
- B. Two PowerStore Manager needs at least two instances for a highly available configuration
- C. Four A customer should install one instance per appliance in the cluster
