  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.

• Question 2:

  A technical architect is working with a customer to design a Dell Unity XT solution The customer is concerned about enabling the data reduction storage service What system condition should the architect recommend for enabling data reduction?

  A. CPU utilization above 80%

  B. Free capacity at or less than 50% free capacity

  C. CPU utilization at or less than 50%

  D. Free capacity above 80%

  Correct Answer: D

  The technical architect should recommend enabling data reduction storage service when the system has free capacity above 80%. Data reduction technologies such as compression and deduplication reduce the amount of storage needed by eliminating duplicates and compressing data. However, these technologies can consume additional resources, particularly CPU. Enabling data reduction on a system that is already running low on free capacity would create additional resource contention and negatively impact performance.

• Question 10:

  What are the two biggest factors that determine IOPS when using SSDs in a Dell EMC SC Series array?

  A. Current latency and queue depth

  B. Application block size and overall throughput

  C. Multi-tenant arrays and tier configuration

  D. Read/write percentage and peak workload

  Correct Answer: B

  The reason there is such a large range in the number of IOPS delivered by SSDs is the IOPS are truly dependent on the type of traffic the SC Series was designed to handle. The two biggest factors that will determine IOPS in an SSD environment are block size of the application and overall throughput.
