How long will the steady state backup group be expected to run?
A customer has a new EMC Avamar server with four 3.9 TB data nodes. This server is backing up
two Avamar clients. The first client has 10 GB of RAM and two file systems. The first file system
has 2 million files consuming .75 TB. The second file system contains 3 million files consuming 1
TB of space. The second client has 8 GB of RAM and one file system containing 4 million files is
consuming 1.2 TB of space. Both clients will belong to the same backup group.
How long will the steady state backup group be expected to run?
what can be done to alleviate the handshake issue?
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 be done to alleviate the handshake issue?
Which calculation will show the best trade-off between retention and compression?
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?
how many CPU cycles are needed by the storage node when backing up clients over the network to local tape driv
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?
What is a probable cause for the decrease in the average ingest rate?
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?

What is the minimum size you would recommend for configuring the stores?
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?
Which operating system and database requirements should be provided to the customer for the DPA server?
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?
What should the customer have done prior to making changes to the configuration?
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?
what is the minimum EMC Data Domain throughput required?
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?
How many Mtrees should be removed to improve the performance?
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?
