NEW QUESTION 84
A Windows client using the SMB protocol is trying to access a multiprotocol file system from a Dell Unity XT NAS server. The local group database was checked and no mapping was found.
What is the next step in the SID to UID resolution process?
- A. Secmap is checked
- B. The Windows user access is removed
- C. The domain controller is checked
- D. The Windows user is mapped to the default UNIX account
Answer: C
Explanation:
Explanation
When a Windows client uses the SMB protocol to access a multiprotocol file system from a Dell Unity XT NAS server, the SID (Security Identifier) of the Windows user is mapped to a UID (User Identifier) on the UNIX file system. If no mapping is found in the local group database, the domain controller is checked to see if the SID is present there. The domain controller can provide the information needed to map the SID to the corresponding UID on the file system, allowing the Windows user to access the files. If the SID is not present in the domain controller, the Windows user's access would be removed.

Answer: D
NEW QUESTION 91
What is achieved by adding a top tier of SSDs when designing a Dell Unity XT hybrid solution with FAST VP and FAST Cache?
- A. Provides an additional data redundancy layer
- B. Isolates file top-talkers I/O from block data I/O
- C. Helps keep paged metadata on FLASH media
- D. Improves compression space efficiencies
Answer: C
Explanation:
Explanation
FAST VP (Fully Automated Storage Tiering for Virtual Pools) and FAST Cache (Fully Automated Storage Tiering for Cache) are features that allow you to optimize the performance of your storage by automatically moving data between different storage tiers based on usage patterns. The SSD tier is used to store frequently accessed metadata, such as file system structures, directories, and inode tables, which are accessed frequently and are small enough to fit in the SSD cache. Keeping paged metadata on flash media improves the overall system performance, as it allows for faster access to the metadata, reducing the latency and the number of I/O operations needed to access it.
NEW QUESTION 92
A company has a Dell Unity XT 880 at its Boston site providing file storage for a business production application The company has a second remote site 8 km (5 mi) away in Cambridge A third site is in New York (342 km (213 mi) from the Boston site) How can the same production data be protected against system outage with a zero RPO and a maximum of 15 minutes RPO data recovery?
- A. Asynchronous replicate from Boston to Cambridge Asynchronous replicate from Cambridge to New York
- B. Synchronous replicate from Boston to Cambridge Synchronous replicate from Boston to New York
- C. Synchronous replicate from Boston to Cambridge Asynchronous replicate from Boston to New York
- D. Synchronous replicate from Boston to Cambridge Synchronous replicate from Cambridge to New York
Answer: B
Explanation:
Explanation
Synchronous replication will provide a zero RPO as all data is written to both the primary and secondary storage at the same time, which means any data written to the primary storage will be instantly available on the secondary storage. This configuration will ensure that the data is protected against system outage, and in case of any failure, the recovery time will be a maximum of 15 minutes as the data is already replicated to the secondary site.

How are vVol datastores mounted in Dell EMC PowerStore storage during the creation of vVol datastores in the vSphere environment shared by ESXi hosts?
- A. VMFS datastores
- B. Volume Groups
- C. Storage containers
- D. Storage Groups
Answer: C
Explanation:
Explanation
A storage container is used to present vVol storage from a PowerStore cluster to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. When a PowerStore cluster is used to provide VM storage, user VMs should be provisioned on the vVol datastores. The default storage container is mounted automatically on the nodes of the cluster.

NEW QUESTION 104
A Dell PowerStore administrator has been asked to create a NAS file sharing environment for several clients.
The clients will be running either Linux (NFS) or Windows (SMB) and must have access to the same data simultaneously How can this be achieved using Dell PowerStore?
- A. Configure a snapshot rule and protection policy and apply it to the file system
- B. Configure multiprotocol access to required file system
- C. Configure file data to be replicated for access by different client types
- D. Configure two NAS servers place all Linux data in one and all Windows data in the other
Answer: B
Explanation:
Explanation
Dell PowerStore allows you to create a NAS file sharing environment for several clients by configuring multiprotocol access to the required file system. This means that the same file system can be accessed by both Linux and Windows clients using either the NFS or SMB protocols. This can be achieved by creating a file system, and configuring it to allow access using both the NFS and SMB protocols. Once the file system is set up, you can assign permissions and share the file system with the appropriate clients. This way, the clients will be able to access the same data simultaneously, regardless of whether they are running Linux or Windows and which protocol they are using. It's not necessary to replicate data for access by different client types, it would be an extra step that would consume more resources and would be unnecessary
NEW QUESTION 105
