Technology Architect Backup and Recovery Solutions Design Exam v12.0 (E20-329)

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

You are recommending a NetWorker deduplication solution with Avamar for a current EMC
NetWorker customer. The customer is planning to back up eight of their existing clients to the Avamar deduplication node.
What is an EMC best practice when performing deduplication backups for these clients?

You aredesigning a backup solution for an EMC NetWorker customer. Based on EMC best practices, how many CPU cycles are needed by tie storage node when backing up clients over the network to local tape drives at a rate of 100 MB/s?

A potential EMC customer has a T1 circuit betweentheir production data centreand their disasterrecoverydata centre that are 2,000 miles apart.Theycurrentlybackup their Linux systems to physical tape usingHP Data Protector Theybackupan average of 20 TB each night.
The customer wants a backup solutionthat improves backup andrestore reliabilitytreduces overall costs.and eliminatesphysical tape.
What is recommended solution?

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?

A customer has asked you to assess their current backup environment. The environment is currently using an offsite physical tape vaulting rotation for compliance purposes.
What is a key concern that you should discuss with the customer?

An Avamar customer is using replication between two data centers. There is a T1 line between the data centers and it is dedicated to Avamar replication. The customer is concerned that Avamar replication is only getting throughput of 1.1 megabits per second during replication.
What should be changed in the design and implementation of this solution?

A customer has an existing environment that uses a Data Domain appliance as a disk backup target. The customer now wants to implement a disaster recovery site using an existing T1 Internet connection. Consider the following:
100 GB of data has been backed up on the primary Data Domain appliance
Retention policy is set for 6 months
What is a best practice implementation for this environment?

A new Avamar customer is concerned with data security since all backup data is stored on disk. To minimize the customer's concerns, you have recommended the encryption-at-rest feature.
What is a consideration when using this feature?

A customer has an existing EMC NetWorker backup group consisting of one file server.
The file server has dual quad-core 2.9-GHz CPUs, 16 GB of RAM, and a single file system with a total of 6 TB of data. Due to a recent loss of backup tapes during shipment, the customer needs to encrypt the backups.
The customer wants to prevent any possibility of backup data being intercepted during the transmission of backup data from the client to the NetWorker storage node. In addition, they want to minimize the change to their file server hardware and minimize operational changes.
Which method meets the customer's requirements?

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?

An EMC NetWorker customer is performing all backups to physical tape. This includes weekly 10 TB backups of static medical imaging data stored on a Dell NAS requiring 8 months retention. Their current tape libraries are approaching end of support life.
The customer has asked EMC for a recommendation that will improve operational backup and restore reliability for their image data with a minimum amount of change. What will meet the customer's requirements?

A customer has Oracle 9i running on a Microsoft Windows server. They want to deploy hot backups because the database cannot be shut down. What is a design consideration for backups when using the Avamar plug-in for Oracle?

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?

A customer is considering implementing an EMC Disk Library with Active Engine Failover
(AEF). Front-end ports 1, 3, and 4 from Engine A will be connected to the SAN. On Engine
B, front-end ports 7, 8, and 11 will be connected to the SAN.
To ensure proper AEF functionality, what is the total number of front-end ports from both engines that need to be connected to the SAN?
