must be built from the same RAID types and sizes
What happens when a reverse synchronization completes without Protected Restore Mode enabled?

The Unified Storage Management plugin for VMware assists in automating the provisioning of storage on a VNX Storage System. What types of storage can be provisioned through the Provision Storage wizard?
NFS, VMFS and RDM
Which RecoverPoint configuration details can be presented in report format when using Data Protection Advisor?
For what reason would you increase the default Ethernet frame MTU on a VNX Datamover?
To match the end-to-end network connectivity to the client
In which file are the audit events defined?
What are the available Usermapper roles?
Primary, Secondary, and Client
A company has many VNX file systems that they currently export using NFS. Their goal is to simplify the management of these file systems for the Linux clients. How can the storage team help the company achieve this goal?
Use the automounter feature with the autofs service to automatically mount file systems.
Which hardware configuration can be a Fail-Safe Network Device?
Two network ports on a single Data Mover configured for active-passive redundancy.
You are configuring the reserve LUN pool on a new VNX. What LUN types can be added to the reserve LUN pool?
Thick pool LUNs and traditional LUNs.
A company has many VNX file systems that they currently export using NFS. Their goal is to simplify the management of these file systems for the Linux client workstations. How can the storage team help the company achieve this goal?
Create a nested mount file system to export all the file systems as a single namespace to mount on the clients.
Which statement correctly describes a benefit of using a Virtual Data Mover (VDM)?
It supports the separation of CIFS servers and their shares.
During the installation process of a VNX for Block and File system, you are prompted to change passwords for the default accounts. Which user password can be changed?
Which protocol is supported by CAVA?
Which RecoverPoint configuration details can be presented in report format when using Data Protection Advisor.?
An administrator has been tasked with mapping all users from corp to their own directory in /Userdata Which is the correct format for the homedirfile configuration?
Which drive type is supported in the 2U, 25-drive DAE5S?
Which action makes CAVA trigger a file scan?
Restoring files from backup
Which Linux kernel supports dynamic LUN scanning?
Which tool is used for scripting SnapView commands in a VNX system?
Which action would cause a VNX Storage Processor A to reboot?
Modifying SPA's Hostname
The file system for an SQL database is running low on available capacity. The database is running on a Windows Server 2008 host connected to a VNX Block array. The file system LUN is configured in a FAST VP enabled pool. How can the storage administrator add capacity without disrupting the users?
Expand the LUN online and then extend the file system on the host
Which statement is valid regarding SnapSure writeable snapshots?
A scheduled refresh on the read-only snapshot will fail if a writeable snapshot exists.
Where can the Secondary Usermapper run?
On physical Data Movers only
A customer has an application that uses a small amount of capacity but has very high performance requirements. Their new VNX is fully virtually provisioned and uses FAST VP storage pools. The customer wants to configure the LUNs for this application on high performance storage. How should the LUNs be initially configured?
Using the Highest Available Tier option.
You are setting up quotas on a file system that will serve up home directories to thousands of users. How can this task be accomplished efficiently?
Configure default hard and soft quota values.
What will be the status of FAST Cache on the LUNs that were created prior to the installation of Fast Cache Enabler?
FAST Cache will be disabled, but can be enabled manually.
What is the minimum number of administrative accounts for a Unisphere storage domain?
A VNX snapshot can have how many snapshots of the source LUN?
What is the correct VNX Block based VAAI operation?
Array Accelerated Full Copy
What is the EMC-recommended cache page size for Microsoft Exchange 2007 environments?
A colleague configured two 512 MB LUNs to be used as Clone Private LUNs (CPLs). When configuring the CPLs, the two 512 MB LUNs do not appear in the list of available LUNs. What do you advise?
CPLs must be 1024 MB or larger.
An administrator tries to modify the quota settings on a CIFS share using a Windows 2000 server, but the Quota tab does not exist in the network drive properties. What could be a possible cause?
Exporting is implemented at the file system subdirectory level on VNX OE for File.
Which should be installed to use the data compression feature of a VNX array?
Compression Enabler and Thin Provisioning Enabler only
What is a critical performance and availability consideration when configuring traditional RAID Groups on a VNX array?
Larger RAID 5 groups have increased risk to availability and higher IO throughput
What is the preferred method for partitioning VNX iSCSI LUNs attached to a Windows Server 2003 host?
What is a critical capacity consideration when configuring traditional RAID Groups on a VNX array?
Larger RAID 5 groups maximize the capacity available
Which three administrative user authentication scopes are provided by VNX?
Global, Local, LDAP

An API for an array to provide its storage capabilities into vCenter.
Which action must be completed before joining a CIFS server to an AD domain?
Configure VNX system time settings.
Where in Unisphere do you assign FAST Cache to LUNs?
At the LUN level under a RAID group
Where can CPLs be created?
In a VNX series array, how does FAST manage data in a heterogeneous storage pool?
