EMC Backup Recovery Solutions Expert Exam for Technology Architects Sample Questions:

Question #1
Click on the calculator icon in the upper left corner.
A customer has an EMC Celerra with two 3 TB CIFS shares in their data center. The data center is equipped with 1 Gb TCP/IP network and 4 Gb SAN infrastructure. The customer has a requirement for full backups once a week and level 1 backups the remaining six days of the week.
Considering the customer has a Fiber Channel tape library with two LTO-3 tape drives that can write at a speed of 120 MB/s, which solution meets the customer's 8-hour backup window?

A. Add a Linux storage node with 10 Gb NIC and configure DSA backups
B. NetWorker with both drives zoned only to the Celerra
C. NetWorker and shared drives between the backup server and the Celerra
D. Allocate one tape drive to the backup server and one tape drive to the Celerra

Question #2
Scenario 1
You have a customer with a large IBM Lotus Domino environment. The customer is in the process of migrating from a UNIX to a Microsoft Windows infrastructure. As part of this process, they are going to perform a refresh of the hardware and software that Domino is running on. In addition, they will migrate all client backups to a new EMC NetWorker environment. The new backup environment consists of a NetWorker server and two storage nodes running on Windows 2008.
The Domino environment consists of a single server running two instances of Domino. The total amount of data that needs to be backed up is approximately 900 GB. The Domino server will have connections to both the SAN and the LAN. They would like to perform hot backups of the databases using the NMDA but are leaving specific design decisions to you.
Additionally, the customer would like to send all data to disk for onsite backups and clone the first full backup of the year to tape for long-term offsite retention. The backup target infrastructure consists of a single Quantum i2000 tape library with six LTO-4 tape drives in addition to two EMC Data Domain 890s. One Data Domain will be located at their primary site. The second Data Domain is at the disaster recovery (DR) site as a replication target for the first.
One of the customer's major concerns is the backup speed of the Domino environment.
They are interested in any best practices they can implement to improve backup performance at the Domino level. Furthermore, they are looking for guidance in using NMDA to backup the data and leverage their backup infrastructure in the most efficient way.
Refer to Scenario 1.
What must be done to ensure the transaction logs and any changed database files are backed up during an incremental backup of each database instance on the server?

A. Domino transactional logging is enabled and set to Linear
B. Domino transactional logging is enabled and set to Archived
C. Backups should be using NetWorker differential levels 1-9
D. \Domino\data\logdir must be included in the saveset

Question #3
You are designing an EMC NetWorker to Data Domain backup solution for a customer using DD Boost. The customer plans to configure an old server to use as a storage node.
Which factor, in the backup environment, affects the amount of memory that this server should have for optimal backup performance?

A. Number of backup clients
B. Amount of backup data
C. Size of the Data Domain system
D. Number of simultaneous save streams

Question #4
Click on the calculator icon in the upper left corner.
You are designing a backup solution for a customer that uses both EMC NetWorker and Data Domain. The customer has stated that they would like to be able to maintain 120 simultaneous sessions to the Data Domain devices.
If using NetWorker 7.6 SP2, what is the minimum number of Data Domain devices that should be configured to meet the requirement?

A. 10
B. 12
C. 6
D. 2

Question #5
Scenario 6
A customer recently implemented an EMC Avamar solution in their primary data center.
The environment consists of several Microsoft applications, including Microsoft SharePoint, Exchange, and SQL. An EMC Data Domain system was also deployed behind Avamar as the backup destination for these applications. There are also several file system clients that have been configured to back up directly to the Avamar server.
One Avamar server and two Data Domain systems have been deployed to support this configuration. The Avamar server is operating close to full capacity and there is no room for expansion since it is already fully provisioned with the maximum number of nodes. The Data Domain systems have plenty of capacity left; each system is currently at 35% of utilization.
Refer to Scenario 6.
After configuring replication for this environment, the source Data Domain system crashed.
What happens when a new backup job is started?

A. Backup immediately fails
B. Backup fails after the timeout period elapses
C. Avamar server caches the data until the source Data Domain system is fixed
D. Data is automatically sent to the target Data Domain system
