A customer is concerned about data remaining on their new EMC Avamar system after an
individual backup is deleted. The securedelete function has been run after the backup was
deleted. To ensure the process is complete, what else should be done?

You are having a preliminary discussion with a prospective customer. The customer would
like to know the deduplication rates that are typically when running initial EMC Avamar
backups for file system and database data. Which information should be provided to the

customer?

As shown in the exhibit, a customer has configured EMC Data Domain for management.
They have noticed performance issues when using the configuration. How many Mtrees
should be removed to improve the performance?

A customer performs weekly full backups and daily incremental backups. A typical full
backup is 5 TB. A full backup completes in 10 hours v incremental backup completes in 4
hours. Based on best practices, what is the minimum EMC Data Domain throughput
required?

A customer is running the backup and recovery configuration shown in the exhibit. They
added a new VMware cluster with 100 virtual machines. They are now experiencing slow
backups at certain times. What should the customer have done prior to making changes to
the configuration?

A customer is interested in using Data Protection Adviser (DPA) for monitoring TimeFinder
replication on their Symmetric arrays. After discussing the Recoverability Analysis features
within DPA, they are interested in a proof of concept. Which operating system and database
requirements should be provided to the customer for the DPA server?

You are designing a Data Protection Advisor (DPA) solution for a customer. As a part of the
engagement, you are required to configure the DPA stores. What is the minimum size you
would recommend for configuring the stores?

A customer wants to know why their backup performance to an EMC Avamar multi-node
server has decreased. Initially they were seeing an ingest rate of approximately 5 to 7
GB/hr/node. Recently they estimated that the ingest rate has slowed to around 3 to 5
GB/hr/node. What is a probable cause for the decrease in the average ingest rate?

You are designing a backup solution for an EMC NetWorker customer. Given a
conservative estimate, how many CPU cycles are needed by the storage node when
backing up clients over the network to local tape drives at a rate of 100 MB/s?

A customer’s environment consists of the following: – Linux servers with an Oracle
database. – Microsoft Windows with SQL. – Full weekly backups for Oracle with a one-month
retention period. – Dairy incremental with a two-week retention. – Full weekly backups for
SQL with two retention periods. You collect the information in order to determine the
capacity needed for an EMC Data Domain solution. Which calculation will show the best
trade-off between retention and compression?
