E20-329 Online Practice Questions and Answers

A customer is using Data Protection Advisor (DPA) to monitor their backup environment. What is a benefit of using remote Collectors?

A. Reduces the amount of information being transferred to the DPA server

B. Collects system-related statistics for a given host

C. Improves the collection performance of backup statistics

D. Provides more complete backup reports

A customer has purchased Data Protection Advisor (DPA) to provide a single enterprise report on backup compliance across their 24 geographically disperse locations. How many DPA servers should be installed?

A. Twenty- four one at each location

B. One in the primary data center

C. Five deployed regionally to balance the load

D. Two in the primary data center for redundancy

You are proposing Data Protection Advisor (DPA) to provide a single reporting interface in a multi-vendor backup environment. The environment consists of IBM Tivoli Storage Manager (TSM), Symantec Net Backup, NetWorker, and Avamar. Each application manages 200 clients.

What needs to be considered with regards to DPA licensing?

A. Avamar requires a separate capacity-based license

B. Avamar requires a client-based license and a capacity-based license

C. TSM client count cannot be combined with other applications

D. Client licenses for all backup applications can be combined

A customer wants to deploy encryption-at-rest for Avamar. When sizing a new solution, which key encryption-at-rest factor(s) should be considered?

A. Consumes more system resources

B. Does not require significant system resources

C. Consumes more resources and requires 35% more disk capacity

D. Requires 50% more disk capacity

A customer is using Data Protection Advisor (DPA) to perform system monitoring of both Microsoft Windows and Solaris clients. When deciding where to place the Collector(s) in the environment, what is a consideration?

A. The Collector installed on the DPA server host can monitor all hosts in the environment.

B. A Collector installed on one of the Windows hosts can monitor other Windows hosts.

C. A Collector must be installed on each Windows host.

D. One Collector is required to monitor Windows hosts and one Collector is required to monitor Solaris hosts.

As shown in the exhibit, a customer has configured EMC Data Domain for management. They have

noticed performance issues when using the configuration.

How many Mtrees should be removed to improve the performance?

A. 1

B. 2

C. 3

D. 4

A customer is piloting an EMC Data Domain system.

Based on the Data Domain statistics shown in the exhibit, which type of data is being backed up?

A. New data

B. DD Boost backups

C. Redundant data

D. Replicated data

A new EMC Data Domain customer has a requirement to store the maximum amount of backup data on their Data Domain system. They are deciding on the type of local compression to use for their backups. When planning the Data Domain design, what should the customer know about the compression types?

A. gz compression uses the least amount of space and the most CPU cycles

B. gzfast compression uses less space and twice as much CPU cycles as gz

C. gz compression uses 30% to 40% less storage space on average than lz

D. lz compression uses the least amount of space and the most CPU cycles

Scenario: The Chief Technical Officer (CTO) of a large company has directed their IT management staff to examine corporate-wide operations and find ways to limit the cost of operations. The corporate directives have prompted the adoption of company policies that include the use of virtualization for all new servers and as many services as possible. The company is subject to government regulations concerning data retention policies for confidential data. Data must be retained for seven years.

An audit of the backup and recovery environment is performed. The exhibit shows a typical site and how it is connected to the disaster recovery environment. Data in the primary site is configured on VMAX storage using FAST-VP to support multiple work load types on a single storage array.

Data is protected by SRDF/A to a remote VMAX which acts as a target for multiple sites. The remote copy of the data is snapped and copied to tape. Retention is accomplished to governmental standards by offsite storage of tape in a remote protected facility.

The company has indicated that it has the following requirements in any proposed architecture for the backup and recovery environment:

Reduced power consumption Reduced floor space consumption Reduced storage capacity consumption Lower WAN bandwidth utilization Shorten RPO Decrease RTO Increase security Lower total cost of ownership (TCO)

Refer to Scenario and the exhibit.

To satisfy the stated requirements, the customer wants to use a virtual appliance to limit power and space consumption in their smaller locations. To replace the current SRDF/A replication model, which EMC technology should be recommended?

A. Avamar Virtual Edition

B. Data Domain

C. NetWorker NDMP

D. File Management Appliance VE

You are having a conversation with an EMC Avamar customer regarding the final design. They indicate that they have certain data that needs to be carefully secured during transit. This data is typically transferred at different times and in different groups.

Which type of encryption would address the customer's concern?

A. AES-256 encryption set at the time of the backup operation

B. AES-128 encryption set at the time of server installation

C. Blowfish encryption enabled at the group policy level

D. AES-256 encryption automatically enabled for all backups
