1. Question 1

   An administrator has configured a Host Group to have access to a storage object.

   What are two benefits of this configuration? (Choose two.)

   AEnsures that snapshots are applied to all LUNs in the group
   

   BProvides multiple hosts the same access to NFS Filesvstems
   

   CProvides multiple hosts access to the same VMFS Datastores
   

   DEnsures that block storage is replicated to the same hosts
   

   EProvides multiple hosts access to the same LUNs
   

   Correct answer: C, E

   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.

2. Question 2

   Which storage objects support Advanced Deduplication?

   AVols and Thick LUNs
   

   BThin LUNs and thin VMFS datastores
   

   CVMFS datastores and vVols
   

   DThin LUNs and thick LUNs
   

   Correct answer: B

   
   

3. Question 3

   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?

   ARestart Management Software
   

   BReinitialize
   C Enable SSH
   

   DReboot Storage Processor
   

   Correct answer: A

   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.

   
   

4. Question 4

   Which I/O modules does the Unity 380/380F system support?

   A12 Gb/s SAS
   2-Port 100 GbE
   

   B32 Gb/s Fibre Channel
   10 GbE Base-T
   

   C12 Gb/s SAS
   10 GbE Base-T
   

   D32 Gb/s Fibre Channel
   2-Port 100 GbE
   

   Correct answer: C

   The Unity 380/380F system supports two types of I/O modules: 12 Gb/s SAS back-end and 10 GbE Base-T front-end. The 12 Gb/s SAS back-end module provides connectivity to the disk drives and expansion enclosures, while the 10 GbE Base-T front-end module provides network connectivity to the hosts and clients. The Unity 380/380F system has four I/O module slots, two for each SP. The 12 Gb/s SAS back-end module must be installed in slot 0 of each SP, and the 10 GbE Base-T front-end module can be installed in slot 1 of each SP. Therefore, the correct answer is C. 12 Gb/s SAS 10 GbE Base-T.Reference:

5. Question 5

   Which firewall ports are required to be open for a successful outbound connection when configuring integrated secure connect gateway?

   A80 and 443
   

   B9443 and 443
   

   C443 and 8443
   

   D80 and 9443
   

   Correct answer: C

   The firewall ports that are required to be open for a successful outbound connection when configuring integrated secure connect gateway are 443 and 8443. Integrated secure connect gateway is a feature that enables secure remote access to the Dell Unity system through the Unisphere Central web portal. It requires an outbound connection from the Dell Unity system to the Unisphere Central server over the internet. Port 443 is used for HTTPS communication and port 8443 is used for WebSocket communication.
