Backup Recovery - Avamar Expert for Implementation Engineers

An EMC Avamar customer is currently using a 2 TB Avamar Virtual Edition (AVE) for their backup environment. They want to begin backing up several Oracle databases and file servers running on a new ESX server. It is determined that a separate AVE should be added to the backup environment for these new backups.
What should be done when implementing the new configuration?

An EMC Avamar customer is running a backup that is being directed to a Data Domain system. The backup has completed successfully; however, it is no longer needed. From Avamar Administrator, the customer manually deletes the backup.
When is the backup data deleted from the Data Domain system?

An EMC employee has been assigned to run securedelete against two clients for a total of 20 GBs on an Avamar server. During a planning discussion with the customer, they want to know what the impact on their Avamar server would be while securedelete is running.
What is the correct response to the customer?

A new EMC Avamar customer wants help in setting up their backup groups and schedules. They are migrating from a traditional tape backup solution with full backups performed once a week and incrementals in between. They have a regulatory requirement to keep an annual backup for seven years but want to keep all other backups for one month. Both Microsoft Windows and Linux clients will be backed up. Based on best practices, what should be recommended?

A customer has an EMC Avamar system backing up a Celerra running DART 6.0 using a single 36 GB NDMP Accelerator Node. They are also going to back up a
VNX OE 7.0 system using the same NDMP Accelerator. Each NAS device has four volumes configured on it. Backups will be configured on the Avamar system for both NAS storage devices to start at the same time.
What will occur when the NDMP backups start using default settings?
