ABC.com is consolidating several arrays of various tiers into a single DMX-4. Their applications
have varying workloads and will be placed on the appropriate tier of storage. Mission-critical
application service levels must be met.
Which feature can be implemented on the new DMX such that applications are serviced by shared
disk resources that are based on customer-assigned criteria?

ABC.com data center has several large FibreChannel SANs supporting AIX, HP-UX, Solaris,
Windows, NetWare, and Linux platforms. They have dedicated a portion of their gigabit network
for iSCSI traffic. The customer is considering a strategy of using iSCSI for every new host that will
not run mission-critical applications.
When evaluating this environment, what should be a primary consideration?

You are working with ABC.com for whom high availability has become a priority because of recent
outages due to single points of failure in their storage infrastructure.
Which components are the most appropriate for the design of the SAN?

ABC.com has a DR site 20 miles (30 km) from their production site. Each site has a CX3-40. As
part of the information gathering process, you determine that their RPO is 15 minutes or less.
They have a total of 30 LUNs that will need to be replicated to the remote site. Their application is
sensitive to response times.
You have gathered Analyzer data for a normal working day. You note the following Analyzer
values:
Write response time: 5 ms
Read response time: 14 ms
Write/s: 400
Read/s: 700
Average seek distance: 23 GB
Which solution should you recommend?

A prospective customer has four applications (A, B, C, and D) with various LUNs they wish to
snapshot. The LUN sizes are as follows:
Application A:
10 GB
20 GB
10 GB
Application B:

25 GB
50 GB
Application C:
150 GB
5 GB
5 GB
Application D:
100 GB
25 GB
According to SnapView best practices, how large should each reserved LUN be in the Reserved
LUN Pool?

ABC.com has a SAN fabric consisting of several MDS-9509s for host to disk array connectivity.
They have purchased a Fibre Channel tape library and want to implement LAN-free backups. You
have proposed making a tape VSAN on the existing MDS infrastructure. The customer is
concerned that the additional traffic on the shared ISLs will consume bandwidth needed by the
disk VSAN. Which feature should you propose to address the customer’s concern?

In an interview with your customer’s backup administrator, you learn that the Exchange backups
are failing frequently. You believe physical database corruption (-1018 errors) is the root cause.
Where should you look for an indication of the source of the problem?

You must design a backup solution for an existing Celerra NS80 customer. The customer has
decided that the expense of expanding their tape hardware infrastructure to support the additional
load is not justified because the technology is not reliable and is outdated.
The customer’s decision criteria are.
1. Performance
2. Least disruption to the production environment
3. Ease of maintenance
Which alternate solution should you use to back up the Celerra?

A Rainfinity solution was installed for a new customer. Before the installation, the customer has
some network concerns.
Which EMC best practice is recommended?

ABC.com has purchased a new NS Celerra to replace an older NSG Celerra that is currently in
production.
You are designing the customer’s upgrade solution. The customer’s data on the current NSG has
mixed protocols:
CIFS and NFS. You would like to use Celerra Replicator V1 to migrate the data to the new
Celerra.
What is a limiting factor for this migration strategy?
