45. A software engineering company has decided to implement shared networked storage to facilitate project development. There are approximately 40 servers in the company; 25% are Solaris and 75% are Windows. The company currently limits growth for storage and does not want to add additional servers for that purpose. They anticipate no more than 30% growth over the next three years.
The storage utilized for the network file systems must be maintained on the most cost-effective solution that is the easiest to manage. However, storage must also be tracked so that the required storage for projects can be charged back to the development teams. Additionally, the network file system will be used for non-project-related storage from other departments such as Human Resources and Accounting. Space allocation for non-project files must be monitored and reports generated for management.
In order to select the most appropriate management application for this environment, you need to analyze specific qualification information. What is the best methodology to collect this information?
A. Collect Grabs from all server systems and process with HEAT. Consolidate the findings and summarize on the qualification document.
B. Interview product development team leads and department heads. Determine current and projected storage requirements and any retention policies currently in use.
C. Provide the EMC qualification document to the customer and have them complete the form.
D. Request network configuration information and performance characteristics. Collect Grabs from all server systems and process with HEAT.
Answer: B

A. Nothing; partition will be seen as 200 GB immediately
B. Run diskpart and set the partition size to 200 GB
C. Run the fdisk command and set the partition size to 200 GB
D. Run the format command and set the partition size to 200 GB

48. A customer likes the de-duplication benefits of an EMC Avamar solution and is interested in implementing it in their environment. The customer would like to know how de-duplication works with restores and has asked you to explain the restore process with Avamar.
How does EMC Avamar construct the files for restores?
A. EMC Avamar checks the client for file blocks that are already present in the client and sends
only the unique blocks back to the client.
B. EMC Avamar checks the local cache on the client for file blocks. If present, it copies those blocks locally and restores the remaining blocks from the server.
C. EMC Avamar checks with the local cache on the client and if a copy of the file is present, it copies the file locally. If the file is not present, it sends the required file from the server to the
client.
D. EMC Avamar reconstructs the entire file on the server and sends the complete file back to the client.
