Answer : A Topic 9, Scenario 34 Your customer has started having problems backing up data and meeting SLA requirements. These problems are partly due to cutbacks in staff and partly due to having to manage more data. The customer is asking EMC for advice and direction regarding a new or improved backup solution. The customer has a large Oracle environment and multiple ESX servers with numerous VMs. Symmetrix VMAX serves as the primary storage for the Oracle environment. Oracle has an extremely high transaction rate with a low data retention requirement of one week. An EMC VNX serves as the primary storage for the VMware environment, which has a more typical retention rate of three to six months. Currently, the customer uses NetWorker with multiple storage nodes and backs up to a physical tape library with multiple LTO-4 tape drives.

You perform an analysis of the Oracle environment and find four Oracle servers. One
NetWorker storage node server has a locally attached FC tape library with six LTO-2 drives.
Full backups are performed each night to quickly recover the databases in the event of a failure. Each night, the 12-hour backup window for Windows systems fails to be met. As a result, users experience noticeable system delays in the morning.
Which cost-efficient strategy allows the backups to complete on time and without any impact to the users?

  • A. Configure each database server as a NetWorker dedicated storage node connected to a SAN-attached EDL. Use the NetWorker Module for Oracle to quiesce the database.
  • B. Attach the tape library unit to a SAN. Dedicate a pair of HBAs to decrease the backup duration.
  • C. Use Avamar to back up the database nightly with RMAN. Perform fast recoveries.
  • D. Add disk space to the VMAX. Use TimeFinder/Clone to increase the performance of the backups.


Answer : A

Your customer continues to aggressively deploy VMs instead of physical servers. With the improved utilization of the ESX servers, backups are starting to extend beyond the backup windows. Additionally, the customer complains about deploying agents to each guest.
What should the customer do to improve the backup environment?

  • A. Deploy NetWorker with the Interoperability module to manage VMware Consolidated Backups
  • B. Implement a Data Domain solution to perform deduplicated backups and reduce ESX server utilization
  • C. Use Replication Manager to perform a VNX SnapView clone and perform a backup of the RDM LUNs
  • D. Perform VMware snapshots of each guest and back up using ESX console backup procedures

Answer : A Topic 10, Scenario 36 Your customer has a traditional LAN-based NetWorker backup infrastructure. They recently acquired another company with an extensive network-based collaborative software design infrastructure. The NAS devices used in the acquired company are all EMC Celerra arrays with CLARiiON and Symmetrix back-ends. The CLARiiON arrays are currently at 60% of total capacity. The Symmetrix arrays are currently at 95% of total capacity. Upon integration of the two environments, the customer discovers that backups are no longer being completed within the allotted backup window. This has caused network congestion and is seriously impacting the customer's software design production environment. EMC Celerra will be retained as the NAS platform for the customer's environment. The customer requires retention of the software development versions onsite for three weeks. Which solution would you advise the customer to implement to lower the impact of operational backups, while allowing for rapid recovery of software version builds? A. Deploy a replicated EMC Centera system to store software development versions with a retention period of three weeks B.

Answer : A Topic 12, Scenario 38 A customer currently has several VNX systems deployed in their 1 Gb Ethernet environment. The VNX systems are used as targets for home directories, document storage, and compliance retention. They have a Microsoft Windows AD environment with 380 Microsoft Windows XP clients that use the VNX-based infrastructure. In addition, several Virtual Data Mover-based CIFS servers are configured to support file sharing requirements on each of the VNXs. All of the production applications are server-based with internal disk storage for the data. There is currently no SAN deployment in the infrastructure and no immediate plans for SAN implementation, as current administration skills are all network-based. The applications include Oracle databases, Oracle production tools, and Microsoft Exchange. The current backup strategy for the VNX systems is over the LAN using EMC NetWorker with a Fibre Channel connected tape library unit containing eight LTO-2 tape devices. The tapes are retained onsite for two weeks before being cycled to an offsite storage facility. The production servers are also backed up to this tape library by using several EMC NetWorker storage nodes. However, any data on the Windows XP clients that is not stored on the VNX shares is currently not protected.

The customer complains about dramatic storage growth and the high cost of maintaining infrequently accessed data on Tier 1 storage. By constantly adding storage to the environment, the backup team struggles with maintaining policies for backing up and restoring data with the limited infrastructure available.
Which solution resolves the customer's problem?

  • A. Deploy VNX File Mover to remove infrequently accessed data from a replicated EMC Centera environment
  • B. Replace the existing tape library with a Quantum I2000 tape library and migrate to LTO- 4 tape technology
  • C. Use Avamar NDMP Accelerator Nodes to reduce the backup window by performing deduplicated incremental backups
  • D. Add Tier 2 NL-SAS storage to the environment and use FAST to migrate data from Tier 1 to Tier 2 disk space
