Question #5
What is a Dell Unity XT best practice to provide the highest network availability for NAS?
- A . Configure LACP with multiple active links.
- B . Configure Fail-Safe Networking with a primary link and a standby link.
- C . Combine LACP and Fail-Safe Networking.
- D . Utilize multi-pathing software such as PowerPath.
Correct Answer: A
A
Explanation:
Configuring Link Aggregation Control Protocol (LACP) with multiple active links is a Dell Unity XT best practice to provide the highest network availability for NAS. LACP enables the bundling of several physical Ethernet links to form a single logical link, thus providing increased bandwidth and redundancy in case of link failures.

Question #7
What is the purpose of the NVMe NVRAM drives in a Dell EMC PowerStore 1000 array?
- A . Read cache and vaulting
- B . Read cache and base OS
- C . Write cache and base OS
- D . Write cache and vaulting
Correct Answer: D
D
Explanation:
The base enclosure is an all-NVMe platform, capable of supporting NVMe SSD, NVMe SCM, and NVMe NVRAM drives. You can populate slots 0 through 20 with NVMe SSD or NVMe SCM drives. Slots 21 through 24 are reserved for NVMe NVRAM drives which serve as additional system write caching. PowerStore 1000 and PowerStore 3000 models contain two NVMe NVRAM drives in slots 23 and 24.

Question #10
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 . Continuous availability
- B . Access-based enumeration
- C . Protocol encryption
- D . Offline availability
Correct Answer: B
B
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.
