You have been asked to design a new backup solution for a customer to satisfy operational
backup requirements. After an initial analysis you decide to implement a two-tier solution. The first
tier is disk; the second tier is tape. A retention period needs to be defined for the first tier that will

determine when backup data will be moved to the second tier.
What is an important piece of information you need to consider when determining this retention
period?

Which environment will yield the optimal data deduplication for backup purposes?

A customer requires a backup host to be located at their primary data center and a tape library at
their disaster recovery data center. The distance between the two data centers is 500 kilometers.
What is the recommended connectivity solution between the data center and the tape library to
address the customer’s requirement?

A customer has purchased Data Protection Advisor (DPA) to provide a single enterprise report on
backup compliance across their 24 geographically disperse locations. How many DPA servers
should be installed?

An EMC NetWorker customer is experiencing poor backup performance, Your analysis determines
that significant host resources are used to manage low-level network handshaking operations
during backup.
Based on EMC recommendations, what can you do to alleviate the handshake issue?

What are the key concerns when discussing the implementation of a Celerra two-way NDMP
backup design utilizing the SnapSure feature?

A customer has asked you to design a backup solution that has a NAS device with several
terabytes of encrypted data spread across three different file systems. Which backup option
should be avoided in this environment?

An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup
performance, they have configured the backup to use four RMAN channels.
The customer wants to benefit from adding Avamar deduplication for this backup. What is a
consideration before proposing this design change?

A customer has twofiles that have been locked and backed up to Data Domain appliance with the
following parameters:
·File1=atime=20 years
·File1=atime=5 years
The Data Domain global retention periods are configured as follows:
·Min=2 years
·Max=10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how
many years can File 2 be deleted?

An EMC NetWorker customer is considering using an EMC Disk Library as a target as shown in
the exhibit. Two storage nodes need to access the same pool of virtual tapes. In addition, the
customer wants to load balance the usage of virtual tape drives across the available connections.
Based on EMC best practices, which satisfies these requirements?
