Scenario A customer is looking to modernize their backup infrastructure. The current
environment consists of a single centralized data center and several remote sites. The
centralized data center hosts all core services and applications. The remote office primarily
consists of sales personnel with 4000 users in North America, 500 in Europe, and 300 in
Asia using file servers. The current backup environment at the primary site uses
CommVault backing up to a Fibre Channel tape library that contains four LTO-4 tape drives.
Currently they are backing up a number of file servers as well as several databases that
have average change rates of 7% daily. Remote office backups are currently performed by
having users copy files to regional file servers that are then backed up to tape. In the past
few months, the customer has experienced problems with getting backups to finish within
their defined windows as well as issues with the tape library hardware. They now have
concerns about gaps in their backup coverage as well as the reliability of the tape media. In
addition, an internal audit shows a large amount of user-generated data is unprotected on
remote user laptops. The customer is looking for a common platform to standardize their
backups. They want a solution which allows for a centralized infrastructure so that they do
not need to rely on remote resources to address hardware and software issues. The other
goal is to move away from tape to a more reliable disk-based solution. Refer to Scenario .
The customer has concerns about Avamar’s ability to handle the backups of their
databases. Which recommendation should be made?

Scenario A customer with a fully virtualized environment has four ESX 4.1 servers in a
cluster with a SAN solution for storage. Each ESX server is hosting 40 virtual machines and
all virtual machines have the same local disk configurations: In addition, the environment
includes a NAS filer. The average time to fully backup all virtual machines on one ESX
server using EMC DD Boost is three hours. The customer is interested in implementing an
EMC NetWorker solution with Data Domain as a backup device. The backup server, storage
nodes, and proxies are SAN-attached. Refer to Scenario . When using EMC NetWorker and
DD Boost, what is the maximum number of concurrent backups per VADP proxy server?

A customer recently implemented an EMC Data Domain system as the backup target for
NetWorker using DD Boost. When reviewing the Data Domain Storage Unit Details report,
you notice that the data drive for a particular client was not deduplicating well but the OS
drive was. What is the most likely cause of the deduplication issue?

Which sizing tool is used to determine the sizing solutions for Avamar and Data Domain?

You are reviewing potential backup opportunities in a customer environment that is currently
using Backup Exec. Which assessment tool will help to provide information about their
current backup and restore success rates?

You have been asked to perform an assessment of a customer’s backup environment. You
want to measure the current network bandwidth before determining any changes to the
backup design. Which tool should you use?

What is a reason for implementing EMC Data Protection Advisor (DPA) in a DPA clustered
architecture?

You are designing an EMC Data Protection Advisor (DPA) installation. What is the minimum
recommended size for a DPA cluster?

You are designing an EMC Data Protection Advisor (DPA) solution for a large NetWorker

customer using both DPA clustering and replication. What is a consideration when
determining the server layout for application and datastore servers in this virtual
environment?
