Question No : 1
The EMC account team has been asked to design a new EMC NetWorker backup solution for Microsoft Exchange Server 2007. The customer's environment consists of Microsoft Exchange Server 2007 hosted on an EMC CLARiiON disk array with EMC VSS Provider and an EMC Disk Library. Your design needs to include a server-less backup solution for the Microsoft Exchange Server 2007 environment by leveraging the Microsoft VSS framework.
What is a recommended approach to meet the customer's requirements?

正解:

Question No : 2
An EMC NetWorker customer is considering implementing NetWorker AES encryption to secure backups on one of their application servers.
What is a concern when using AES?

正解:

Question No : 3
The EMC account team has been asked to design a NetWorker backup solution for a Microsoft Exchange server. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.
The customer wants to leverage the Microsoft VSS framework to protect the Exchange Server 2007 CCR environment.
What needs to be considered when designing a backup solution?

正解:

Question No : 4
The EMC account team has been asked to design a NetWorker backup solution. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library. The customer wants to leverage the Microsoft VSS framework to back up their Exchange server from the Exchange Server 2007 CCR passive node.
What needs to be considered when designing this backup solution?

正解:

Question No : 5
A customer performs weekly full backups and daily incremental backups. A typical full backup is 5 TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an incremental backup completes in 4 hours.
Based on best practices, what is the minimum Data Domain throughput required?

正解:

Question No : 6
A customer has two files that have been locked and backed up to the Data Domain appliance with the following parameters:
• File1 = atime = 20 years
• File2 = 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 File2 be deleted?

正解:

Question No : 7
Maintain NetBackup as their primary tool for backup control and visibility
What should be included with a high-end Data Domain appliance?

正解:

Question No : 8
An EMC customer is evaluating a single-engine EMC Disk Library (EDL) system. They placed the EDL on their test infrastructure and performed 15 simultaneous backup jobs. The customer is concerned that the overall performance numbers are substantially lower than the published numbers. Each job is sent to a separate virtual tape at an average rate of 18 MB/s. The EDL is connected to the SAN through two FC ports at 4 GB/s. There are a total of 15 LUNs for virtual tape storage. The infrastructure has been certified to sustain performance in excess of the EDL's capability.
What would you recommend to improve the overall performance?

正解:

Question No : 9
A customer is interested in using a Remote Copy policy to replicate data between two single-engine EMC Disk Library (EDL) systems. The customer is concerned about the readiness of replicated tapes in case of a failure on the source system.
What can be done to minimize the exposure on the target?

正解:

Question No : 10
A customer uses EMC NetWorker on HP-UX to back up 20 TB per day to physical tape. They currently restore 10 TB of database data twice a week. The customer needs a new backup solution that will reduce backup and restore times and is highly available.
What is a recommended EMC solution?

正解:

Question No : 11
A potential EMC customer has a T1 circuit between their production data center and their disaster recovery data center that are 2,000 miles apart. They currently back up their Linux systems to physical tape using HP Data Protector. They back up an average of 20 TB each night. The customer wants a backup solution that improves backup and restore reliability, reduces overall costs, and eliminates physical tape.
What is a recommended solution?

正解:

Question No : 12
A customer is interested in implementing two DL4000 systems. One system is located at a central site. The second is at a remote site as a target for Remote Copy operations. Policies will be configured to replicate certain tapes to the target.
Which process is necessary to make the virtual tapes available on the target?

正解:

Question No : 13
An EMC NetWorker customer is planning on directing the backups of a database server to the single-engine EMC Disk Library (EDL) as shown in the exhibit. The data to be backed up is accessed by the host through a redundant connection and resides on primary storage.



Based on EMC best practice, what needs to be adjusted in the solution?

正解:

Question No : 14
An EMC NetWorker customer is currently performing all backups to physical tape. This includes multiple 7 TB databases with 2 weeks retention. Their current tape libraries are approaching end of support life. The customer has asked for an EMC recommendation that will improve operational backup and restore reliability.
What will meet the customer's requirements?

正解:

Question No : 15
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?

正解:
