    data to smaller virtual disks.

B. Use array based virtualization to migrate the

    data to smaller virtual disks.

    present the extra space to other hosts.

D. Contact the system administrators and have

     them justify the storage that is allocated to

     them.

scenario and have proposed several risk reduction strategies. Which two measurements

differentiate the strategies? (Choose two.)

B. 4

C. 5

D. 6

A cascade network topology can be used for which two purposes? (Choose two.)

A. Create a fault resilient storage network with

    two or more switches.

B. Interconnect multiple switches together that

    are local or remote via ISLs.

C. Connect two or more switches where all

    switches do not have to have direct access to

    each other.

D. Establish a storage network that enables all

    switches regardless of number of switches to

    connect to each other.

Which demonstrates a strong potential for data center error(s)?

A. Unrestricted vendor access to infrastructure for

    immediate resolution issues

B. Precise documentation that outlines steps to

    perform during common fault conditions

C. Defined roles and scope or all employees that

    service and maintain infrastructure equipment

D. Approved change control process that limits

    actions to the infrastructure to those who are

    qualified

A heterogeneous SAN consists of one RAID with four LUNs, one hub, and four servers. How

should you assign one LUN to each server while preventing other servers from accessing other

LUNs?

A. Configure the HBA for persistent binding

B. Disable the undesired LUNs in the operating

    system disk manager of each server

C. Use the array LUN masking feature to assign

    RAID LUNs to HBA WWPNs in the servers

D. Substitute the hub with a switch and use soft

    zoning to assign RAID LUNs to HBA WWNs in

    the servers

Which two data protection techniques provide the highest level of data protection and rapid

recovery? (Choose two.)

A. Local mirroring with backup to tape.

B. Backup to disk combined with RAID disk data

    protection.

C. RAID-0 with mirrored write back cache and

    battery backup.

D. Remote mirroring with consistency groups and

    backup to alternate storage.

A customer has created a disaster recovery (DR) plan and is synchronously replicating its data to

a remote facility. The remote storage/server needs to be configured (LUN masking, zoning, and rescanning the SCSI bus). To failover the application, what must the customer do?

A. Failover storage, re-configure the remote

    storage/server, start application

B. Failover storage, start application, re-configure

    the remote storage/server

C. Pre-configure the remote storage/server,

    failover storage, start application

D. Pre-configure the remote storage/server, start

    application, failover storage

A network backup server is attached to a SAN. The server's two HBAs deliver 60 MB/s each to

the tape devices. The tape library attached to the SAN includes 15 MB/s tape devices. Theoretically, how many tape devices are required to efficiently stream output from the tape server?

A. 4

B. 8

C. 12

D. 15

Which tool configures persistent binding in a SAN?

A. Zoning tool

B. Hba software

C. Switch manager

D. Backup software

You have been asked to design a SAN/NAS that stores data that will be internally read by web

browsers for data replay. Some browsers are more likely to render a readable version of a

standards-based page, whereas some browsers will have problems rendering table-based

data, invalidating your design. What should you implement in your design to mitigate these

concerns?

A. A NAS solution that tracks users browser use

B. A SAN solution that tracks users browser use

C. A NAS solution that segregates the data types

    for browser reading

D. A SAN solution that segregates the data types

    for browser reading

You have been tasked with designing an iSCSI based storage network that support 24 servers at

a primary location attached to a 2TB storage array including a tape library with four tape drives. In addition, there are 18 branch offices each with at least one Windows server that eeds to gain access to primary storage, tape, and file sharing. Which two should be considered as part of his design? (Choose two.)

A. Determine if current switches support 802.11g

    and jumbo frames.

B. Upgrade the remote network to 1Gb to every

    device and install iSCSI hardware adapters.

C. Assess network topology (bandwidth, available

    ports, current workload) and file server

    utilization and the onnectivity needs of

    storage and tape.

D. Look at available network bandwidth at

    primary location and to remote facilities and

    ability of current nfrastructure to support more

    devices and bandwidth.

A company is adding a NAS solution to its existing infrastructure. Their current network

infrastructure is overloaded. After implementing the NAS solution what will the network

experience?
