EMC Technology Architect Backup and Recovery Solutions Design (E20-329) Free Practice Test
Question 1
An EMC Avamar customer wants to start backing up their VMware environment. The customer's goal is to have image-level backup while having a low impact on the ESX server. In addition, they want the ability to perform file-level restores of their Microsoft Windows clients.
Which backup method will meet the customer's needs?
Which backup method will meet the customer's needs?
Correct Answer: B
Question 2
Your customer has been a long time Avamar Virtual Environment (AVE) customer. They have older AVE installations along with newer installations. They notice that older configurations are not receiving the same performance as the newer configurations.
The customer points out that both configurations have fairly high I/O requirements but use different disk pools. They understand performance is affected by RAID levels and would like your recommendation.
Based on best practice, which RAID level is recommended for virtual machines with high disk usage?

Correct Answer: B
Question 4
Refer to Scenario .
A customer is looking to modernize their backup infrastructure. The current environment consists of a single centralized data center and several remote sites. The centralized data center hosts all core services and applications. The remote office primarily consists of sales personnel with 4000 use-North America, 500 in Europe, and 300 in Asia using file servers.
The current backup environment at the primary site uses CommVault backing up to a Fibre Channel tape library that contains four ITO-4 tape drives. Currently they are backing up a number of file servers as well as several databases that have average change rates of 7% daily Remote office backups are currently performed by having users copy files to regional file servers that are then backed up to tape.
In the past few months, the customer has experienced problems with getting backups to finish within their defined windows as well as issues with the tape library hardware. They now have concerns about gaps in their backup coverage as well as the reliability of the tape media. In addition, an internal audit shows a large amount of user-generated data is unprotected on remote user laptops.
The customer is looking for a common platform to standardize their backups. They want a solution which allows for a centralized infrastructure so -they do not need to rely on remote resources to address hardware and software issues. The other goal is to move away from tape to a more reliable disk-based solution.
The customer is evaluating EMC Avamar as a possible solution to backup their remote users. They are estimating that each machine will take approximately 10 minutes to backup. They would like all backups to complete in 8 hours.
What is the minimum number of storage nodes needed to support the necessary connections to complete the backups of the North American system in the defined window?

Question 5
A customer has an existing EMC NetWorker backup group consisting of one file server. The file server has dual quad-core 2.9-GHz CPUs, 16 GB of RAM, and a single file system with a total of 6 TB of data. Due to a recent loss of backup tapes during shipment, the customer needs to encrypt the backups.
The customer wants to prevent any possibility of backup data being intercepted during the transmission of backup data from the client to the NetWorker storage node. In addition, they want to minimize the change to their file server hardware and minimize operational changes.
Which method meets the customer's requirements?

Question 6
Refer to 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 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 has to 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 noted 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)
The company has been unable to achieve the RTO required by their Service Level Agreement to their major clients. If they want to limit TCO, which EMC solution should be proposed?

Question 7
A customer wants to back up VMware using EMC Avamar to leverage deduplication. They want to use the VMware Image Backup option. Which component of the backup environment requires the Avamar client agent?
Correct Answer: C
Question 8
An EMC NetWorker customer is currently backing up data to four Advanced File Type devices.
The customer wants to use an additional device for new streams once there are eight running on a single device. Backups should not queue if another device is unavailable.
Which parameter should be set?

Question 9
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?
