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 
 
Answer: D     
 
Explanation: 
Unity 600 delivers 1.2 TB to 3.0 PB max raw capacity. 
 
Question: 2

A. 4.0 
B. 5.0 
C. 5.5 
D. 6.0 
 
Answer: C

Question: 3 
   
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 
 
 
Answer: A     
 
Explanation: 
Asynchronous Unified Replication is available natively on UnityVSA. This allows file and block resources 
to be replicated between UnityVSA systems, between UnityVSA and physical Unity systems, and also 
locally back to the same UnityVSA system 
 
Question: 4 
   
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 
 
Answer: D     
 
Explanation: 
A sample from a Broadcomm BIOS is provided in the figure below, illustrating the IQN assignment for 
the VNX iSCSI target.

Question: 5 
   
 
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 PerformanceSAS: Performance 
B. Flash: PerformanceSAS: Capacity 
C. Flash: Extreme PerformanceSAS: Capacity 
D. Flash: CapacitySAS: Performance 
 
Answer: A     
 
Explanation: 
Hybrid pools can have up to 3 tiers (Extreme Performance, Performance, and Capacity). 
For the Extreme Performance tier, use only SAS Flashdrives. 
For the Capacity tier, use only SAS drives. 
 
Question: 6 
   
What describes the LUN Snapshot Copy operation? 
 
A. Parent cannot be a snapshot copyCan only copy a detached snapshotHas an independent Retention 
Policy from the parent 
B. Parent can be a snapshot copyCan only copy a detached snapshotHas an independent Retention 
Policy from the parent 
C. Parent can be a snapshot copyCan copy an attached or detached snapshotInherits the parent 
Snapshot Retention Policy 
D. Parent cannot be a snapshot copyCan copy an attached or detached snapshotInherits the parent 
Snapshot Retention Policy 
 
Answer: B     
 
Explanation: 
Note: You can create copies of LUNs by cloning LUNs from the Snapshot copies in a volume. These 
FlexClone LUNs are readable and writable copies of the LUNs as the LUN existed when the Snapshot 
copy was created. Before you can clone a LUN, you must create a Snapshot copy (the backing Snapshot 
copy) of the LUN you want to clone.

Question: 7 
   
Which technology is used by Unity Snapshots? 
 
A. Copy on First Write 
B. Inline Deduplication 
 
C. Redirect on Write 
D. Block Compression 
 
Answer: C     
 
Explanation: 
The technology used for snapshots of both block and file resources in Unity is called redirect on write. 
 
Question: 8  
   
DRAG DROP 
What is the correct sequence of steps taken by the storage array when an AC power failure is detected? 
 
Answer:  
Storage processors 
Power 
BIOS 
SP Cache 
Array 
The Battery Backup Unit (BBU) provides power to the Storage Processor in the event that cabinet power 
is lost. The BBU is designed to power the SP long enough for the system to store SP cache content to the 
M.2 SSD device before powering down. The BBU includes sensors which communicate its charge and 
health status to the SP. In the event the BBU is discharged the SP will disable cache until the BBU has 
recharged. In the event the BBU has faulted or cannot sustain enough charge, an alert will be generated.

Question: 9 
A system administrator is configuring asynchronous remote replication for an existing NAS server and 
its' file systems on a Unity system. What should the administrator create to ensure all data is replicated 
for the NAS server and the file system? 
 
A. Replication sessions on each file system only 
B. Replication sessions for each file system first and then the NAS server 
C. A replication session on the NAS server and then manually create replication sessions on each file 
system 
D. A replication session for only the NAS server 
 
Answer: D
