- A. Dynamic Pools
- B. Asynchronous Replication
- C. iSCSI Connectivity
- D. NVMe Connectivity
- E. FC Connectivity
Answer: B,C
Explanation:
Explanation
The Dell UnityVSA is a software-defined storage solution that runs the Dell Unity operating environment on a VMware ESXi server. The Dell UnityVSA provides the same features and functions as the Dell Unity hardware platform, such as block and file storage, snapshots, thin clones, data reduction, replication, and encryption. Some of the features of the Dell UnityVSA are:
iSCSI Connectivity: The Dell UnityVSA supports iSCSI connectivity for block storage access. The iSCSI protocol enables hosts to communicate with the DellUnityVSA over an IP network and access LUNs as SCSI devices. The Dell UnityVSA can support up to 64 iSCSI interfaces and up to 256 iSCSI sessions per interface.
Asynchronous Replication: The Dell UnityVSA supports asynchronous replication for block and file storage. Asynchronous replication is a feature that copies data from a source storage resource to a destination storage resource over a network at scheduled intervals. Asynchronous replication can be used for disaster recovery, data migration, or backup purposes. The Dell UnityVSA can support up to
256 replication sessions per system.

NEW QUESTION # 19
A company has an ESXi host installed with FC HBAs that is connected to a Dell Unity XT storage array. A
500 GB LUN is provisioned to this host from the Unity array and is in production. The VMware administrator has configured a new vSwitch with the NICs on the server intended for iSCSI traffic. The storage administrator is asked to configure software iSCSI and provision a new 1 TB LUN from the storage array using iSCSI.
What is a consideration when satisfying this request?
- A. Two iSCSI target interfaces must be configured with IP addresses from separate subnets.
- B. A connection must be established between the host iSCSI initiators and Unity iSCSI targets before provisioning the new LUN.
- C. Any single host should connect to any single array using one protocol only.
Answer: C
Explanation:
Explanation
Mixing FC and iSCSI protocols for the same host and array is not supported by Dell EMC Unity. This can cause issues with multipathing, failover, and performance. The best practice is to use one protocol per host and array pair. If the host needs to access both FC and iSCSI LUNs from different arrays, then separate vSwitches and port groups should be used for each protocol.

NEW QUESTION # 20
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 # 21
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 # 22
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. I6.0 TB
- C. 3.2 TB
- D. 3.58 TB
Answer: D
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 # 23
A system administrator deployed a UnityVSA to their vSphere environment. They did not add the management IP to the UnityVSA during the installation.
Which command must be used to apply the management IP from the vSphere UnityVSA console?
- A. svc_inject
- B. svc_initial_config
- C. svc_change_hw_config
- D. svc_ipmi
Answer: B
Explanation:
Explanation
To apply the management IP from the vSphere UnityVSA console, the system administrator must use the svc_initial_config command. This command allows the user to configure the initial network settings for the UnityVSA, such as the management IP address, subnet mask, gateway, and DNS servers. The svc_ipmi command is used to configure the IPMI settings for the UnityVSA, such as the IPMI IP address, username, and password. The svc_change_hw_config command is used to change the hardware configuration of the UnityVSA, such as the number of CPU cores, memory size, and disk size. The svc_inject command is used to inject faults into the UnityVSA for testing purposes.

What is the purpose of a Proxy NAS server?
- A. Access snapshots for testing production NAS servers.
- B. Increase security of production NAS servers.
- C. Increase performance for shared network connections that access 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.

What are two prerequisites when creating host configuration for NFS client? (Choose two.)
- A. Tenant information
- B. Hostname
- C. Network Address
- D. Subnet access
Answer: B,C
Explanation:
Explanation
Host configuration is the process of defining the host properties and access permissions for a host that connects to the Dell Unity XT system. For NFS clients, the host configuration requires two prerequisites:
Network Address: The network address is the IP address or the subnet mask of the NFS client that identifies the host on the network. The network address is used to register the host on the Dell Unity XT system and to grant access to the NFS filesystems.
Hostname: The hostname is the name of the NFS client that is resolved by the DNS server or the local hosts file. The hostname is used to display the host information on the Unisphere UI and to enable host monitoring and alerting.

NEW QUESTION # 26
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. All VMs on a datastore are snapped simultaneously.
- D. They enable the automatic import of capability profiles from vSphere to Unisphere.
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.

What is the maximum number of drives on a traditional RAID Group?
- A. 8 drives
- B. 16 drives
- C. 64 drives
- D. 32 drives
Answer: B
Explanation:
Explanation
The maximum number of drives on a traditional RAID group depends on the RAID type and the drive type.
For RAID 5 and RAID 6, the maximum number of drives is 16 for all drive types. For RAID 1/0, the maximum number of drives is 32 for SAS and NL-SAS drives, and 16 for SSD drives. References: Dell EMC Unity: Best Practices Guide2, page 17.
NEW QUESTION # 29
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. Disable the Data Reduction.
- C. Perform Local LUN Move.
- D. Chanqe Tierinq Policy to Auto-Tier.
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 # 30
On a Dell Unity XT file system asynchronous replication session, how many system Snapshots are required to support replication?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Explanation
On a Dell Unity XT file system asynchronous replication session, four system Snapshots are required to support replication. Two system Snapshots are created on the source file system, and two system Snapshots are created on the destination file system. The source system Snapshots are used to track the changes that need to be replicated, and the destination system Snapshots are used to apply the changes and maintain a consistent point-in-time copy of the source data. The system Snapshots are automatically created and managed by the replication engine and are not visible to the user.

NEW QUESTION # 31
What is a characteristic of FAST VP?
- A. Fast VP data relocation runs in the background at all times once it is enabled.
- B. Users can set the Fast VP data relocation rate.
- C. Fast VP optimizes data replacement by moving 1 GB slices between disk tiers.
- D. Users can enable or disable FAST VP at the LUN level.
Answer: B
Explanation:
Explanation
FAST VP (Fully Automated Storage Tiering for Virtual Pools) is a feature that automatically moves data within a storage pool based on the performance requirements and access patterns of the data. FAST VP data relocation runs in the background according to a user-defined schedule and rate. The schedule determines when the data relocation starts and ends, and the rate determines how much system resources are used for the data relocation. Users can set the Fast VP data relocation rate to High, Medium, Low, or None. High means that the data relocation has the highest priority and uses the most system resources, while None means that the data relocation is disabled. Fast VP data relocation does not run at all times, but only during the scheduled window. Fast VP optimizes data placement by moving 256 MB slices between disk tiers, not 1 GB slices.
Users cannot enable or disable FAST VP at the LUN level, but only at the storage pool level.

NEW QUESTION # 32
Into what size slices is the LUN partitioned for RAID extents?
- A. 512MB
- B. 256 MB
- C. 128 MB
- D. 64 MB
Answer: C
Explanation:
Explanation
A LUN is a logical unit of storage that is presented to a host as a SCSI device. A LUN is composed of one or more RAID extents, which are the smallest units of storage that can be allocated to a LUN. A RAID extent is a slice of a RAID group that is used to store user data and parity information. The size of a RAID extent depends on the RAID type and the drive type of the RAID group. For example, a RAID 5 extent on a SAS drive is 128 MB, while a RAID 6 extent on a NL-SAS drive is 256 MB. The LUN is partitioned into slices that match the size of the RAID extents, and each slice is mapped to a RAID extent from a RAID group in the storage pool. The LUN slices are distributed across multiple RAID groups to improve performance and availability. References:
