The EMC account team has been asked to redesign a NetWorker backup solution. The existing backup environment consists of one NetWorker server and one storage node to back up approximately 80 clients. Over time, the amount of data increased, resulting in daily backups taking more than 24 hours to complete.
Analysis has determined that the tape infrastructure and the network are not the bottleneck. What would you recommend to improve the backup performance with minimal costs?

A customer is implementing s Data Domain system with two expansion shelves. They require that access to the data can be reached even when a single path fails. The customer does not want the HBA card to be the single point of failure.

A.

B.

C.

D.

Which critical network elements are assessed by the Network Assessment Tool?

An EMC NetWorker customer performs all backups to physical. The customer backs up file systems, application servers, VMware guests multiple 10 TB database, and a large 20 TB NetApp filer. They have a primary and disaster recovery data center with an OC-12 circuit between the two sites.
The customers physical tape libraries are approaching end of support life and they are looking to replace them with deduplication technology. In addition, they want to improve NDMP backup times for their 20 TB NetApp filer.
Which recommendation will address the customers requirements?

A customer has approached you to advise them on how their backup environment will integrate into their new iSCSI application server deployment. Which network characteristic would have the greatest impact on their backup environment?

A customer has a database server with 300 GB of Oracle database data. Using the default hash cache setting, what is the total amount of physical RAM required on the client?

What is a key consideration when assessing a nested mount file system and an NDMP Volume Based Backup (VBB) backup strategy?

An EMC NetWorker customer is considering using an EMC Disk Library as a target as shown in the exhibit. Two storage nodes need to access the same pool of virtual tapes. In addition, the customer wants to load balance the usage of virtual tape drives across the available connections.
Based on EMC best practices, which satisfies these requirements?

A customer has twofiles that have been locked and backed up to Data Domain appliance with the following parameters:
✑ File1=atime=20 years
✑ File1=atime=5 years
The Data Domain global retention periods are configured as follows:
✑ Min=2 years
✑ Max=10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how many years can File 2 be deleted?

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

A customer has asked you to design a backup solution that has a NAS device with several terabytes of encrypted data spread across three different file systems.
Which backup option should be avoided in this environment?

What are the key concerns when discussing the implementation of a Celerra two-way NDMP backup design utilizing the SnapSure feature?

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 you do to alleviate the handshake issue?

A customer has purchased Data Protection Advisor (DPA) to provide a single enterprise report on backup compliance across their 24 geographically disperse locations. How many DPA servers should be installed?

A customer requires a backup host to be located at their primary data center and a tape library at their disaster recovery data center. The distance between the two data centers is 500 kilometers.
What is the recommended connectivity solution between the data center and the tape library to address the customers requirement?

Which environment will yield the optimal data deduplication for backup purposes?

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?

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?

An EMC NetWorker customer is considering using the deduplication feature with Avamar. What is a requirement when performing backups to a deduplication node?

A customer has recently added a Celerra to their environment and has asked you to assess their current data protection methodology. They currently have an
EMC NetWorker environment using an EMC Disk Library (EDL) as the primary backup location before they move the virtual tapes to physical tapes.
How over, the rate of change of the data on the Celerra is too high for their RPO using the EDL for single file recovery if their backups are performed only at the end of the business day. What would you incorporate to lessen the impact of their once-a-day backup schedule on the Celerra data with minimal impact to their backup administration processes?

You are designing a backup solution for an EMC NetWorker customer. Based on EMC best practices, 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 plans to integrate an EMC Disk Library (EDL) with NetWorker. The customer has purchased an Embedded Storage Node License to clone virtual taped from the EDL to a physical tape library.
What should be included in the design document design to ensure the Embedded Storage Node reads the data from virtual tape during a clone operation?

A customer is considering the use of offsite physical tape vaulting rotation for compliance purposes. What is a key concern to discuss with the customer?

While running a three-month pilot using a Data Domain appliance, a customer produces the space utilization graph shown in the exhibit.
What does the "saw tooth" line for the compression ratio represent?

You are designing an EMC NetWorker deduplication solution for a customer. When performing a restore of a backup containing multiple save sets from a deduplication node.
What is the maximum number of save sets that can be recovered concurrently?
