NEW QUESTION # 19
Which feature can be configured for a Dell Unity XT file system NFS share?
- A. Protocol Encryption
- B. Host Access Level
- C. Access-Based Enumeration
- D. Distributed File System
Answer: B
Explanation:
Explanation
A feature that can be configured for a Dell Unity XT file system NFS share is the Host Access Level. This feature allows the user to specify the access permissions for each host or host group that is allowed to access the NFS share. The access permissions can be set to Read/Write, Read Only, or No Access. The Host Access Level feature can be used to control the security and performance of the NFS share. Access-Based Enumeration, Protocol Encryption, and Distributed File System are features that can be configured for a Dell Unity XT file system SMB share, not NFS share.

NEW QUESTION # 20
A storage administrator must configure replication from a production Dell Unity XT 680F to an offsite DR Dell Unity XT 480. Block resources must be replicated without data loss if the production site becomes unavailable. File resources can be replicated with an acceptable amount of data difference on the destination.
What replication configuration meets the requirements?
- A. Set Unisphere resource filtering to All.
- B. Configure the replication interfaces on the 4-port mezzanine card.
- C. Configure the replication connection mode to Both.
- D. Set an RPO of 0 on the synchronous replication sessions.
Answer: C
Explanation:
Explanation
To meet the requirements, the replication connection mode must be set to Both, which allows both synchronous and asynchronous replication sessions to be configured on the same connection. This way, block resources can use synchronous replication, which ensures zero data loss, and file resources can use asynchronous replication, which allows some data difference on the destination. Setting Unisphere resource filtering to All is not necessary, as it only affects the display of resources in the Unisphere GUI. Setting an RPO of 0 on the synchronous replication sessions is redundant, as synchronous replication always has an RPO of 0. Configuring the replication interfaces on the 4-port mezzanine card is not relevant, as it only affects the performance and availability of the replication network.

NEW QUESTION # 21
A storage administrator recently disabled the Advanced Deduplication on a LUN.
Which Dell Unity XT action can be used to remove the Advanced Deduplication savings from LUN?
- A. Unmask the LUNfrom host.
- B. Chanqe Tierinq Policy to Auto-Tier.
- C. Perform Local LUN Move.
- D. Disable the Data Reduction.
Answer: C
Explanation:
Explanation
When Advanced Deduplication is disabled on a LUN, the existing data that was deduplicated remains in its reduced state, and only new data written to the LUN is not deduplicated. To remove the Advanced Deduplication savings from the LUN, the administrator must perform a Local LUN Move operation, which copies the data from the source LUN to a destination LUN without deduplication. The destination LUN must have Advanced Deduplication disabled, and must be in the same storage pool as the source LUN. After the Local LUN Move is completed, the source LUN can be deleted and the destination LUN can be renamed as the original LUN. References: Dell Unity: Data Reduction2, page 9.
NEW QUESTION # 22
What is the correct sequence of steps to provision storage for SMB NAS clients?
Answer:
Explanation:
Explanation
The correct sequence of steps to provision storage for SMB NAS clients is:
Group hard drives into storage pools. This allows you to create a pool of storage resources that can be allocated to different types of storage objects, such as NAS servers, file systems, and LUNs.You can create different pools based on the performance and capacity requirements of your applications1 Create a NAS server for an existing pool. A NAS server is a logical entity that provides file-level access to clients using SMB, NFS, or FTP/SFTP protocols. You need to create a NAS server before you can create file systems and shares.You can specify the pool, network settings, domain membership, and other properties for the NAS server2 Create file systems and file system shares based on the supported NAS protocol. A file system is a logical container that stores files and folders on a NAS server. A file system share is a logical representation of a file system that can be accessed by clients using a specific protocol. For SMB NAS clients, you need to create SMB file system shares that support the SMB protocol.You can configure the share name, permissions, access policies, and other settings for the SMB share3 Map the shared file system to the client. This allows the client to access the files and folders on the SMB share using a drive letter or a UNC path.You can use the Windows Explorer or the net use command to map the shared file system to the client4
NEW QUESTION # 23
An administrator notices that the communications between Unisphere and the storage system get interrupted.
Which service task should the administrator perform to fix the issue with minimal impact?
- A. Reinitialize
C Enable SSH - B. Reboot Storage Processor
- C. Restart Management Software
Answer: C
Explanation:
Explanation
The service task that the administrator should perform to fix the issue with minimal impact is Restart Management Software. This service task restarts the management software on both storage processors without affecting the data services or the host I/O. This can resolve the communication issues between Unisphere and the storage system. Reinitialize, Enable SSH, and Reboot Storage Processor are service tasks that have more impact and risk than Restart Management Software.

NEW QUESTION # 24
Which two actions are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system? (Choose two.)
- A. Use standard NIC for iSCSI.
- B. Manually register host on storage array.
- C. Interfaces should be on separate subnets.
- D. Use private network for iSCSI interfaces.
Answer: C,D
Explanation:
Explanation
Two actions that are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system are to ensure that the interfaces are on separate subnets and to use a private network for iSCSI interfaces. These actions can improve the performance, security, and availability of the iSCSI network. Having interfaces on separate subnets can prevent broadcast storms, reduce network congestion, and enable multipathing. Using a private network for iSCSI interfaces can isolate the iSCSI traffic from other network traffic, reduce the risk of interference or attacks, and simplify the network configuration. Manually registering host on storage array and using standard NIC for iSCSI are not recommended actions, as they can introduce errors, inefficiencies, and limitations.

NEW QUESTION # 27
What is a benefit of using vVols?
- A. They enable the assignment of isolated file storage partitions.
- B. Individual VMs on a datastore can be snapped.
- C. They enable the automatic import of capability profiles from vSphere to Unisphere.
- D. All VMs on a datastore are snapped simultaneously.
Answer: B
Explanation:
Explanation
A benefit of using vVols is that individual VMs on a datastore can be snapped. vVols are virtual volumes that are stored on a storage array and managed by vSphere. They enable granular control and management of VM storage. With vVols, each VM has its own set of virtual disks that are mapped to corresponding storage objects on the array. This allows the array to perform snapshot operations on individual VMs without affecting other VMs on the same datastore.

NEW QUESTION # 28
A storage administrator has a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and
1.2 TB of FAST Cache.
What is the total cache availability for caching the flash drives?
- A. 1.39 TB
- B. 3.58 TB
- C. I6.0 TB
- D. 3.2 TB
Answer: B
Explanation:
Explanation
The total cache availability for caching the flash drives on a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and 1.2 TB of FAST Cache is 3.58 TB. This is calculated by adding the system memory (RAM), the FAST Cache, and the pool cache. The system memory is 192 GB, which is equivalent to
0.18 TB. The FAST Cache is 1.2 TB, which is a dedicated cache for the flash drives. The pool cache is 2.2 TB, which is a portion of the flash drives that is reserved for caching the pool data. Therefore, the total cache availability is 0.18 + 1.2 + 2.2 = 3.58 TB.

NEW QUESTION # 29
An administrator has configured a Host Group to have access to a storage object.
What are two benefits of this configuration? (Choose two.)
- A. Provides multiple hosts access to the same VMFS Datastores
- B. Provides multiple hosts access to the same LUNs
- C. Ensures that snapshots are applied to all LUNs in the group
- D. Provides multiple hosts the same access to NFS Filesvstems
- E. Ensures that block storage is replicated to the same hosts
Answer: A,B
Explanation:
Explanation
A Host Group is a logical grouping of hosts that share the same access permissions to storage objects, such as LUNs, VMFS Datastores, or NFS Filesystems. By configuring a Host Group, an administrator can simplify the management of multiple hosts and ensure consistent access to the storage resources. Some of the benefits of using a Host Group are:
Provides multiple hosts access to the same VMFS Datastores: A VMFS Datastore is a block-based storage object that is formatted with the VMware File System (VMFS) and used to store virtual machine files. A VMFS Datastore can be shared by multiple hosts that are part of a VMware cluster. By adding these hosts to a Host Group and assigning the VMFS Datastore to the Host Group, the administrator can ensure that all the hosts have the same access permissions and can access the virtual machines on the Datastore.
Provides multiple hosts access to the same LUNs: A LUN is a block-based storage object that is presented to a host as a SCSI device. A LUN can be shared by multiple hosts that have the same operating system and use a cluster-aware file system. By adding these hosts to a Host Group and assigning the LUN to the Host Group, the administrator can ensure that all the hosts have the same access permissions and can access the data on the LUN.

NEW QUESTION # 30
Which are two ways to create an asynchronous replication session for a NAS server? (Choose two.)
- A. Use NAS server properties.
- B. Create replication connect.
- C. Use the NAS server wizard.
- D. Create replication interface.
Answer: A,C
Explanation:
Explanation
Two ways to create an asynchronous replication session for a NAS server are to use NAS server properties and to use the NAS server wizard. Both methods allow the user to select a source NAS server and a destination NAS server, and configure the replication settings, such as the RPO, the replication schedule, and the replication mode. Creating a replication connection or a replication interface are not ways to create an asynchronous replication session for a NAS server, but rather prerequisites for enabling replication between two Dell Unity systems.

What three VMware datastore types can be defined by using UI or CLI interfaces from the Dell Unity XT platform? (Choose three.)
- A. RDM
- B. SMB
- C. VMFS (Block)
- D. vVol (Block)
- E. NFS (File!
Answer: C,D,E
Explanation:
Explanation
VMware datastore is a logical container that holds virtual machine files and other data. There are three types of VMware datastore that can be defined by using UI or CLI interfaces from the Dell Unity XT platform:
vVol (Block): A vVol datastore is a block-based storage object that is formatted with the VMware Virtual Volumes (vVol) framework and used to store virtual machine files and metadata. A vVol datastore can be created by using the Unisphere UI or the UEMCLI interface on the Dell Unity XT system. A vVol datastore can provide granular control, policy-based management, and improved performance for virtual machines.
NFS (File): An NFS datastore is a file-based storage object that is formatted with the Network File System (NFS) protocol and used to store virtual machine files and other data. An NFS datastore can be created by using the Unisphere UI or the UEMCLI interface on the Dell Unity XT system. An NFS datastore can provide scalability, flexibility, and efficiency for virtual machines.
VMFS (Block): A VMFS datastore is a block-based storage object that is formatted with the VMware File System (VMFS) and used to store virtual machine files and other data. A VMFS datastore can be created by using the Unisphere UI or the UEMCLI interface on the Dell Unity XT system. A VMFS datastore can provide high performance, reliability, and compatibility for virtual machines.

NEW QUESTION # 32
What is the purpose of a Proxy NAS server?
- A. Increase security of production NAS servers.
- B. Increase performance for shared network connections that access NAS servers.
- C. Access snapshots for testing production NAS servers.
- D. Access snapshot replicas on the destination side of a replicated file resource.
Answer: D
Explanation:
Explanation
The purpose of a Proxy NAS server is to access snapshot replicas on the destination side of a replicated file resource. A Proxy NAS server is a temporary NAS server that is created on the destination system to mount a snapshot replica of a replicated file system. This allows the user to access the data on the snapshot replica for testing, recovery, or other purposes. A Proxy NAS server does not increase performance or security of production NAS servers, nor does it access snapshots for testing production NAS servers.
