Question 1 of 158

A storage administrator has requested a recommendation on upgrading their VNX5600 to a comparable Unity storage array. The solution requires a maximum capacity of 3.5 PB.

To meet the administrator's requirement without over provisioning the capacity, which Unity Hybrid storage array is recommended?

A.

Unity 300

B.

Unity 400

C.

Unity 500

D.

Unity 600

Correct Answer: D

The Unity 600 is recommended because it delivers a maximum raw capacity of up to 3.0 PB, which is the closest to meeting the requirement of 3.5 PB without over provisioning the capacity. The Unity 300, Unity 400, and Unity 500 models have lower maximum raw capacities, with the Unity 400 and Unity 500 being particularly insufficient for the needed capacity. Therefore, the Unity 600 best meets the requirements.

Question 2 of 158

What is the minimum VMware Hypervisor version a server must be running in order to support the deployment of a UnityVSA system?

A.

4.0

B.

5.0

C.

5.5

D.

6.0

Correct Answer: D

The minimum VMware Hypervisor version required to support the deployment of a UnityVSA system is 6.0. UnityVSA installation documentation specifies that a 64-bit ESXi host running version 6.0 or later is required.

Question 3 of 158

Which feature is supported on a UnityVSA operating environment?

A.

Asynchronous Replication

B.

MCC Write Caching

C.

Quick Start Pool Provisioning

D.

Data at Rest Encryption

Correct Answer: A

UnityVSA supports asynchronous replication, which allows for file and block resources to be replicated between different UnityVSA systems, between UnityVSA and physical Unity systems, and even locally back to the same UnityVSA system. This feature is crucial for disaster recovery and ensures data availability across different environments.

Question 4 of 158

A storage administrator is creating a host profile in Unisphere to provide host access to block storage resources using the iSCSI protocol. The host initiators were not automatically discovered and must be manually added.

In addition to the SAN host IQN, what other configuration can be performed through the "Create iSCSI Initiator Wizard" window?

A.

Enable and disable CHAP settings

B.

Create Mutual CHAP secret

C.

Create Global CHAP secret

D.

Enter CHAP username and secret

Correct Answer: D

D

A sample from a Broadcomm BIOS is provided in the figure below, illustrating the IQN assignment for the VNX iSCSI target.

Question 5 of 158

A storage administrator is configuring a storage pool on a Unity system containing Flash disks and SAS disks. What tier will the system assign to each of the disk types?

A.

Flash: Extreme Performance SAS: Performance

B.

Flash: Performance SAS: Capacity

C.

Flash: Extreme Performance SAS: Capacity

D.

Flash: Capacity SAS: Performance

Correct Answer: A

In a Unity storage system, Flash disks are typically assigned to the Extreme Performance tier because they provide the highest level of performance. SAS disks are assigned to the Performance tier as they deliver high performance but not as high as Flash disks. NL-SAS or Nearline SAS disks would be used for the Capacity tier, which focuses more on large storage capacity rather than high performance. Therefore, Flash disks will be assigned to the Extreme Performance tier, and SAS disks to the Performance tier.
