Scenario
A customer is looking to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment. The environment consists of:
A primary data center - NetWorker server, Data Domain, and Avamar A disaster recovery (DR) data center - Data Domain only 220 remote sites Each remote site consists of approximately 30 clients and 1 storage node LAN speed at and between all sites is 1 Gb
The company's Chief Technology Officer (CTO) has indicated that data must be backed up locally. Then, the data must be copied offsite to the primary data center and DR data center. The entire solution must be managed from a single unified interface in order to configure and track backup jobs.
The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years on tape at the DR data center.
Each remote storage nodes' device will have a target session of 12 and a max target session of 60. By default, what is the maximum nsrmmd count per device?

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

An EMC Avamar customer has a heavily utilized ESX system CPU utilization is a concern. Each guest system, all of which are Linux must be backed up with file granularity. The customer has both Avamar and NetWorker available and is looking to EMC for guidance
What is considered the most suitable approach to meet these requirements?

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 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 8 GB of RAM and two file systems. The first file system has 3 million files consuming .75 TB. The second file system contains 5 million files consuming 1 TB of space. The second client has 10 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?

A customer is planning a new database rollout using Oracle and wants to perform online backups. Initial tests with EMC NetWorker have shown that the backups cannot be completed within the backup window of six hours.
You have analyzed the backup environment and there are adequate resources to meet this backup window. What is one of the first things to check in NetWorker or RMAN to increase performance without adding cost and complexity?

A customer is considering an EMC Avamar backup solution. They want to know whether Avamar can provide the security benefit of data encryption between the clients and the Avamar server.
What are the in-flight encryption considerations?

An EMC NetWorker customer wants to use the deduplication option. The requirement for a database server in their environment is to perform deduplication backups for file system data and NetWorker tape backups for database data. They want to allow a maximum of two parallel streams for file system backups and a maximum of four streams for database backups.
How can this be accomplished?
Exhibit A

Exhibit B

Exhibit C

Exhibit D

Refer to the Exhibit.


A large mining company wants to implement replication using EMC Data Domain systems in multiple cities. How should the customer's design requirements be addressed?

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?

After a backup assessment, you determined that customer data deduplicates well. After deduplication, the data consists of 100 laptops and desktops with .5 TB, a file server with 5 million files in 1 TB, and several database servers with 5 TB. The customer requires deduplication with the shortest possible backup window.
Which solution should be architected with as few components as possible?

While designing an EMC Data Domain solution, you need to determine the required amount of storage capacity. The following information was gathered from the customer:
2 TB full backup @ 5x compression
10% daily data change rate
4 incremental/week @ 10x compression
1x full per week @ 25x compression
Retention period = 4 weeks with no data growth
-----
What is the minimum amount of storage needed to support this solution?

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?
