What are members of an EMC Avamar group policy?
Dataset, Schedule, and Retention
What is the minimum physical memory that needs to be allocated to an EMC Avamar Virtual Edition with 2 TB of licensable capacity?
Due to a scheduling conflict, an EMC Avamar administrator had to cancel the backup of a client using the Avamar Administration GUI. What happens to the backup data that had already been sent to the Avamar server?
Data is retained for seven days as a partial backup
A customer is unable to connect to their EMC Avamar server when using the Avamar Administrator GUI. If default settings are being used, which port must be open for a successful connection?
What is the purpose of running the EMC Avamar Virtual Edition benchmark process?
Verify that the performance of the disk storage meets specifications
An EMC Avamar customer, without premium support, has a requirement to be able to recover from a failed storage node. What is the minimum amount of nodes, of all types, that is required to support this functionality?
A customer is running out of capacity on their Avamar Gen4 server with 3.9 TB nodes. They want to add three Gen4 1.3 TB nodes from their test lab. Can these 1.3 TB nodes be repurposed for node additions in this environment?
