What is the most likely reason for the performance issue?
A customer has two EMC VNX, one at the primary site and the other at a DR site located 100 km
away. The WAN connection between sites is a 100 Mb/s dark fiber link with 4 ms latency.
A previous storage administrator configured the pool LUNs for the file system on thin LUNs. The
file system is growing at a rate of 500 GB per week and is on a VDM. The new storage
administrator reports performance issues with the file system.
What is the most likely reason for the performance issue?
What is represented by data flow in the picture?

Which method will the system use to bind the LUNs?
A customer has upgraded his NS700 to NAS 5.4 code and would like to implement backup to disk
with RAID 3 on his new ATA drive shelf. He will use the user defined template option. Which
method will the system use to bind the LUNs?
Which is a feature of hardware-assisted locking?
A customer plans to connect ESXi 5.0 hosts to a new EMC VNX array. They want to take
advantage of the hardware-assisted locking feature in VAAI. Which is a feature of hardware-assisted locking?
which SAN Manager folder are inactive zones maintained?
In which SAN Manager folder are inactive zones maintained?
What should be done on the Celerra side?
Your customer has a Windows NT domain environment and a Celerra (v5.1). The customer would
like to upgrade this domain to Windows 2003 and use SMB Signing. What should be done on the
Celerra side?
Which property would they examine?
A customer wants to create a file system for a highly sequential application. They plan to use the
EMC VNX AVM feature to create the file system, using the clarsas_archive pool in a RAID 5 (4+1)
configuration. They want to know how much data is being written to each dvol in the pool entry.
Which property would they examine?
What do you advise the customer regarding Data Mover interfaces and CIFS servers for the DR solution?
You are planning a CIFS DR solution with an EMC VNX for File. The customer wants to use LACP
(Link Aggregation Control Protocol) on the Data Movers to provide additional network redundancy
for the solution.
What do you advise the customer regarding Data Mover interfaces and CIFS servers for the DR
solution?
How would you troubleshoot the problem?
The Windows administrator of ABC Corp. has changed local security policy to audit logon events
from success to failure to identify logon problems reported from certain users. The company does
not allow automatic security updates in their domain.
After one week the System Administrator has not received any logon entry in the Eventlog from
the Celerra CIFS server within that domain. How would you troubleshoot the problem?
How do you advise the customer?
A customer has a production CLARiiON replicating to a secondary CLARiiON at a remote site
using MirrorView/S. The customer wants to upgrade to new EMC VNX, but due to cost
constraints, they can only upgrade one of the CLARiiON arrays at this time.
