What are characteristics of the LUN Snapshot Copy operation?
The Snapshot Copy operation will make a copy of an existing snapshot that is either attached or detached from a host. The copy will capture the existing data state of the snapshot it copies. In this Copy example, a copy of an existing 4 o clock snapshot is being made. The copy inherits the parent snapshot data state of 4 o clock and its retention policy

Question No : 12
A storage administrator wants to configure a Unity system to join the list of arrays remotely monitored for activity and system status using Unisphere Central. The security policy on the Unisphere server was set to “automatic”.
What additional security information must be specified in the Unisphere Settings window to enable communication with Unisphere Central?
Configure the security policy to specify how storage systems are verified when connecting to Unisphere Central. Automatic verification automatically verifies storage systems when they connect to Unisphere Central using a preconfigured security certificate hash and passphrase.

Question No : 13
How long will a Copy Back operation take when a hot spare is invoked?
Note: Starting with Release 24, you can now use a proactive hot spare for proactive disk replacement.
Before Release 24 you had to remove the physical disk to replace in order to force a rebuild. During the rebuild phase, the RAID group was "degraded" and at risk.
Three main benefits of using a proactive hot spare:
- Avoiding "uncorrectable errors" due to media problems during the rebuild process.
- Greatly reduce the risk of having a degraded RAID group, and the risk of having a double-faulted RAID group.
- Performance - a copy to hot spare is faster than a normal rebuild.
Question No : 14
A user is having difficulty troubleshooting a Unity storage system and the service provider has been contacted for assistance. The service provider needs to run some service commands on the Storage Processors to troubleshoot the issue further.
Which step must be taken to allow the service provider remote access to the storage system?
Question No : 15
In order to replace a faulty component, a service provider has placed one of the Unity Storage Processors into Service mode.
Once the component is replaced, how is the Storage Processor brought back into Normal mode?
If a single Storage Processor (SP) comes up in Service Mode, in Unisphere, you need to reboot the SP to return it to Normal Mode.
