Example Questions

A customer performs weekly full backups and daily incremental backups. A typical full backup is 5 TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an incremental backup completes in 4 hours. Based on best practices, what is the minimum Data Domain throughput required? An EMC NetWorker customer is considering implementing NetWorker AES encryption to secure backups on one of their application servers. What is a concern when using AES? A customer is planning a new database rollout using Oracle and wants to perform online backups. Initial tests with NetWorker have shown that the backups cannot be completed within the backup window of 6 hours.

Refer to Scenario 4. An enterprise customer would like to better address business continuity at all branch offices. Their corporate data center resides in Chicago, Illinois and they would like all branch office data centers to use Chicago as the destination for replicating backups. Each branch office has a mixture of databases, e-mail, and other data that need full backups on Friday evenings and daily incremental backups. Based on their new Chief Technology Officer's experience with deduplication, they are installing EMC Data Domain devices at all sites to take advantage of the lower bandwidth requirements for backup replications. The backup requirements for the branch offices are: New York, Denver, and Houston = 100 GB full, 20% daily incremental SCO, Seattle, and Kansas City = 20 GB full, 20% dairy incremental The San Francisco branch office has an existing VTL infrastructure. Which type of replication is recommended for their backups? Scenario A customer is looking to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment. The environment consists of: - A primary data center - NetWorker server, Data Domain, and Avamar - A disaster recovery (DR) data center - Data Domain only - 220 remote sites - Each remote site consists of approximately 30 clients and 1 storage node - LAN speed at and between all sites is 1 GB The company's Chief Technology Officer (CTO) has indicated that data must be backed up locally. Then, the data must be copied offsite to the primary data center and DR data center. The entire solution must be managed from a single unified interface in order to configure and track backup jobs. The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years on tape at the DR data center. Each remote storage nodes' device will have a target session of 12 and a max target session of 60. By default, what is the maximum nsrmmd count per device? A customer's backup environment consists of an EMC Avamar 6.1 integrated Data Domain solution. A large portion of the backup data comes from Microsoft Exchange servers.

What can be used to determine the health of their backup environment? An existing EMC NetWorker customer has recently undertaken an LDAP authentication network infrastructure reconfiguration to ensure an improved validation response time. The reconfiguration does not involve the addition of any physical network hardware to the infrastructure. However, they have now approached you to assist with an increased latency they are experiencing on their network. What is the most likely cause of their increased latency after the reconfiguration? In a customer's backup environment, EMC Avamar is integrated as a deduplication node with NetWorker. The customer wants to run multiple simultaneous backups from the same client. What is the recommended maximum number of simultaneous streams? A customer has difficulty keeping up with their restore requests on their existing backup solution. Currently each restore requires the backup team to engage and manually process each restore request. The customer wants the clients to be able to restore and browse their own data using only their account credentials. Which EMC solution meets the customer's requirements? A customer would like to add their many desktop/laptop clients to their EMC NetWorker backup environment. Their requirements for the desktop/laptop clients are: - Clients must be able to restore their own data - Deduplicated backup storage used for backups Based on EMC best practice, which solution is recommended?

A customer with an existing VMware infrastructure is interested in Avamar as a potential backup solution. The customer needs to back up 10 virtual machines with a total of 2.9 TB of data. The daily change rate is 6 GB per day. Which solution would you recommend? An existing EMC NetWorker customer is evaluating options for upgrades within their backup solution. The customer is interested in replacing their current tape-based infrastructure with a backup-to-disk product. The customer currently uses EMC VNX arrays for their SAN storage. The solution needs the ability to retain certain backups for long periods of time due to compliance reasons as well as minimize the amount of power and rack space required. In addition, all backups must go offsite on a daily basis. Finally, the customer wants the ability to use a new 10 GigE infrastructure they are planning to deploy within their data center.

During the final sizing of this solution, what should be taken into consideration? A customer has a new EMC Avamar server with four 3.9 TB data nodes. This server is backing up two Avamar clients. The first client has 8 GB of RAM and two file systems. The first file system has 3 million files consuming .75 TB. The second file system contains 5 million files consuming 1 TB of space. The second client has 10 GB of RAM and one file system containing 4 million files is consuming 1.2 TB of space. Both clients will belong to the same backup group. How long will the steady state backup group be expected to run? An existing EMC NetWorker customer has been backing up their VMware environment using VMDKs to a CIFS-attached EMC Data Domain system. Recently, they have added another 80 TB to their primary VM storage. While their deduplication rates have exceeded expectations, they are starting to overrun their backup window. Which solution compliments their existing infrastructure? A customer has data at several remote offices that need to be backed up over a secure Internet connection to their data center.
