Example Questions

In an EMC NetWorker backup environment, where do the metadata and backup policies reside? If multiple backup streams are written to a backup device at the same time, which feature is being used? An EMC NetWorker customer wants to passphrase-protect the data backup stream from a specific client. Which directive should be configured for the client? A company has numerous UNIX servers that are being backed up to the Data Domain system as a disk target. Which transport protocol should be configured on the Data Domain system? Which Data Domain feature is used to selectively replicate data written to the Data Domain Virtual Tape Library (DD-VTL) by the backup software? What is a key advantage of Data Protection Advisor? What is an Avamar checkpoint? To consolidate backup servers, which component plays an important role in EMC NetWorker backup planning? A customer is planning to implement an EMC Disk Library with Active Engine Failover in their switched fabric environment. What is a requirement? You are asked to propose a serverless backup solution for the following environment: * Oracle database running on HP-UX 11i and all datafiles reside on an EMC Symmetrix disk array. * EMC TimeFinder/Mirror is used to create a copy of the Oracle data. * Mirror copy of the Oracle data is backed up by a Sun Solaris 10 server. Which EMC product would you recommend to support this environment? Which technology is used in an EMC Disk Library to provide tolerance against a double drive failure? By default, which database is automatically deployed on the Data Protection Advisor server? An administrator wants to back up an EMC Celerra with Avamar using a single NDMP accelerator node. Based on EMC best practices, what is the maximum number of files that can be backed up per backup job? Which operating systems can be used to install a Data Protection Advisor server? Where is most duplicate data on the Data Domain system discovered? You are asked to propose a serverless backup solution for the following environment: - Oracle database running on HP-UX 11i and all datafiles reside on an EMC Symmetrix disk array. - EMC TimeFinder/Mirror is used to create a copy of the Oracle data. - Mirror copy of the Oracle data is backed up by a Sun Solaris 10 server. Which EMC product would you recommend to support this environment? A customer is using the NetWorker Module for Microsoft Applications (NMM) to protect the following environment: - Microsoft Exchange Server 2007 using Cluster Continuous Replication (CCR) that resides on an EMC CLARiiON disk array. - A Microsoft Volume Shadow Copy Service hardware provider is used to create point-in-time copies of production data. What is a characteristic of an NMM backup operation? Using the EMC Avamar sizing tool, you have determined that a customer requires four 2 TB data nodes. Since the customer is protecting only 5 TB of data, how is the additional storage used? A customer requires the ability to recover data while backups are being written to the same media. Which EMC NetWorker device type supports this operation? A customer has an existing environment where a tape library is the target for backups. The tapes are then shipped offsite where they are stored and can be used for disaster recovery. The customer wants to eliminate the tape library and any truck delivery but still have copies sent offsite. They want to keep their backup process in place. What is the most efficient type of Data Domain replication that meets this requirement? A customer plans to deploy deduplication in an EMC NetWorker environment. For data backed up to the deduplication node, where is the metadata in the form of hashids sent? How is the communication between a Data Protection Advisor Collector and the Server performed? You are backing up two different NAS servers, each with direct-attached tape drives. Backup Client X has 10 files of 100 MB each. Backup Client Y has 1,000 files of 1 MB each. What will happen under identical backup infrastructures? Which EMC NetWorker policy is configured to define the length of time that records are retained in the Client File Index? An EMC Disk Library customer is considering using Remote Copy between two engines. A policy will be configured to copy data when 50 MB of data is sent to the virtual tape. How does the data transfer occur? An Avamar administrator wants to run multiple backups from their Celerra through their single NDMP accelerator node. Based on EMC best practices, what is the recommended maximum number of backup jobs that the administrator can run at once, assuming there is enough RAM? Due to a bottleneck on the LAN, a potential EMC customer is unable to meet their current SLA on backups. Which Avamar characteristic addresses the customer's issue? A customer is using the NetWorker Module for Microsoft Applications (NMM) to protect the following environment: * Microsoft Exchange Server 2007 using Cluster Continuous Replication (CCR) that resides on an EMC CLARiiON disk array. * A Microsoft Volume Shadow Copy Service hardware provider is used to create point-in-time copies of production data. What is a characteristic of an NMM backup operation? An EMC customer is implementing an EMC Disk Library (EDL) as the primary target for backups using NetBackup. After a predefined period of time, data needs to be moved from the EDL to physical tape. Data movement to physical tape and recovery from physical tape should occur without manual intervention. Which feature satisfies these requirements? An EMC Avamar customer is expanding their backup environment to include their many virtual machines in addition to their physical file servers. Which Avamar deployment provides the least amount of change to their existing backup procedures? Which Avamar feature provides the benefit of less network traffic than traditional backup applications? What is the access mode of the EMC Avamar server during the garbage collect activity? An EMC NetWorker customer is implementing an EMC Disk Library with the Embedded Storage Node feature on both engines. Active Engine Failover is also configured. In case of a failover, which component from the failed engine will be missing on the surviving engine? What is the key benefit to implementing Symantec's NetBackup OST with Data Domain systems? A customer has a critical 700 GB application that is CPU and disk intensive. The backup window for this application is one hour. Which backup method would you recommend for this application? An EMC NetWorker customer needs to improve the RTO for all backups retained onsite. Most of the backup jobs consist of images and other scientific data. The customer requires daily tape out for long-term offsite retention. Which product addresses these challenges? An EMC customer has an EMC NetWorker server running on a Microsoft Windows host and two storage nodes running on Solaris hosts. Data Protection Advisor (DPA) will be installed on a separate Windows host. The customer requires that system performance information be collected from the backup server and all storage nodes. A Collector will be installed on the DPA server by default. At a minimum, how many additional Collectors need to be deployed? Given an RPO, which factors must be considered when designing an EMC NetWorker backup solution? A customer's environment currently has a backup window that exceeds the replication window. Which Data Domain characteristic will solve this issue? A customer, using Avamar version 4, wants to use VMware Consolidated Backup (VCB) to back up their version 3.x ESX servers. Which operating system(s) can they run on their proxy server? What is the default port used by the Avamar avtar process on the client for unencrypted communication with a storage node on the Avamar server? When does the Avamar server run garbage collection? An Avamar customer has just deployed a VMware environment. The customer wants to ensure they receive the highest level of deduplication within the environment. Which type of backup should be performed? In a Data Protection Advisor environment, what is monitored by Predictive Analysis Engine rules? In an EMC NetWorker datazone, which component stores the online databases that track backups and volumes? The backup window of a customer using tape as a target for the current backup solution has increased over the allowed time. The customer needs to reduce the backup window by adding an intermediary process to a faster device before going to tape. What is that process? Where is deduplicated data stored on a Data Domain system? In an EMC Avamar system, which operation is allowed with standard replication? On an Avamar server using default settings, what is the maximum allowable operating system capacity utilization after which HFS check will not run? Which Avamar node is dedicated to providing internal Avamar server processes and services?
