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?

svc_ipmi
svc_change_hw_config
svc_initial_config
svc_inject

Answer(s): C

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.

QUESTION: 8

An administrator has configured a Host Group to have access to a storage object.
What are two benefits of this configuration? (Choose two.)

Ensures that snapshots are applied to all LUNs in the group
Provides multiple hosts the same access to NFS Filesvstems
Provides multiple hosts access to the same VMFS Datastores
Ensures that block storage is replicated to the same hosts
Provides multiple hosts access to the same LUNs

Answer(s): C,E

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.

QUESTION: 9

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

12 Gb/s SAS
2-Port 100 GbE
32 Gb/s Fibre Channel 10 GbE Base-T
12 Gb/s SAS 10 GbE Base-T
32 Gb/s Fibre Channel 2-Port 100 GbE

Answer(s): C

Explanation:

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.

QUESTION: 10

Multiple I/O modules must be installed in Dell Unity XT 680 storage.
Which module must be installed in slot 0?

4-Port 25 Gbps Ethernet
4-Port 16 Gb Fibre Channel
4-Port 10 Gbps Ethernet
12 Gb/s SAS back-end

Answer(s): D

Explanation:

The Unity XT 680 system supports four types of I/O modules: 12 Gb/s SAS back-end, 4-Port 16 Gb Fibre Channel, 4-Port 25 Gbps Ethernet, and 4-Port 10 Gbps Ethernet. The 12 Gb/s SAS back-end module provides connectivity to the disk drives and expansion enclosures, while the other three types of modules provide network connectivity to the hosts and clients. The Unity XT 680 system has six I/O module slots, three for each SP. The 12 Gb/s SAS back-end module must be installed in slot 0 of each SP, and the other modules can be installed in slots 1 and 2 of each SP. Therefore, the correct answer is D. 12 Gb/s SAS back-end.
