Which type of errors does the TimeFinder Integration Module for Exchange scan for prior to
a backup?

A customer has the following storage configuration for a specific application: – Symmetrix
VMAX 4 engine with 128 GB cache per engine – SRDF/A with two 1 Gbps links to remote
site – 4.2 TB of logical volumes configured for SRDF/A replication – SMC / SPA installed for
storage management The customer is periodically experiencing high response times for the
application. How can the customer use SPA to determine the potential cause of the high
response times?

You have been tasked with gathering performance data for a Microsoft SQL server
database that will be migrated to a Symmetrix VMAX. Which Perfmon counter must you
measure prior to designing a disk layout?

Which Symmetrix VMAX component is involved in measuring sampled average response
time?

Your customer has security and management concerns with SRDF and Timefinder scripts
that are currently running on many production hosts. Symacl will be used to reduce or limit
storage management controls to two centralized management servers. How can your
customer finish migrating the scripts after symacl is enabled?

Which change in a Symmetrix VMAX workload will typically result in an increase in the read
hit rate?

A new data warehouse will be hosted on an existing 4-engine VMAX array. The database
server has 4 HBAs connected at 8Gb/s. Due to limited SAN switch ports only port 0 on each
VMAX FA is connected – also at 8Gb/s. The workload is expected to require at least
1700MB/s of reads @ 128KB I/O size. It must maintain performance in case of any major
component failure in the host, switch or array. Assume that the existing workload on the
VMAX does not exceed 350MB/s per port. Also assume that the ports can sustain up to
500MB/s without exceeding 70% utilization. What is the best practice HBA to FA mapping to
ensure the required performance of the data warehouse?

Cascaded SRDF is running in SRDF/A mode from the source (R1) site to the disk-based
secondary (R21) site. Which SRDF mode is permitted between the R21 and the R2 sites?

A company uses VMware ESXi Servers and Symmetrix VMAX storage arrays. Which EMC
Virtual Storage Integrator feature allows the allocation of new Symmetrix VMAX storage to
Virtual Machines from the VMware vSphere client?

A company has a VMware vSphere 5.0 ESXi host using NUMA. This host is experiencing
poor performance. Which BIOS settings on the ESXi host could help alleviate this
performance issue?
