A customer currently has a multi-node EMC Avamar server with eight active storage nodes.
They are currently at 85% GSAN capacity and receiving capacity warning messages. The
customer would like to purchase four additional nodes for the system. What is a best
practice for adding capacity?

A data center company is using two EMC NetWorker servers (NetWorker_A and
NetWorker_B). Each server has three storage nodes to protect 650 server applications and
data. The total amount of data being backed up is 100 TB. NetWorker_A server protects 60
TB and NetWorker_B server protects 40 TB. To minimize cost and simplify licensing
management for NetWorker, the company decided to switch from a traditional licensing
model to a capacity licensing model. How many licenses are needed to support the
company’s requirements?

A customer has data at several remote offices that needs to be backed up over a secure
WAN connection to their data center. However, bandwidth is constrained. A major portion of
their backup data will be file system data. In addition, they have a 6 TB database in the
primary data center with a 6% change rate that needs to be backed up. Which EMC backup
solution is recommended for this customer?

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?
