Question 1 Multiple choice

iSCSI is best used for _____. (Choose two.)

  1. A

    minimizing the amount of data transferred over the FCIP link

  2. B

    connecting stranded servers to the SAN

  3. C

    NAS block services

  4. D

    additional controller pairs to effectively use available bandwidth

Show answer and explanation

Correct answers: B, C

Question 2 Single choice

What is the result of merging a zoned fabric with a non-zoned fabric?

  1. A

    Devices that were in the non-zoned fabric are not accessible until they are added into the current enabled configuration.

  2. B

    Devices in the fabric are not accessible until the devices in the non-zoned fabric are zoned and made part of the effective configuration.

  3. C

    Any devices that were in the non-zoned fabric are automatically configured into a new zone as part of the effective configuration so they can function.

  4. D

    The fabrics do not merge. They segment and require manual intervention.

Show answer and explanation

Correct answer: A

Question 3 Single choice

What is a design property of the Core+Edge+Leaf SAN topology?

  1. A

    It can start at one switch and grow almost without limit.

  2. B

    It allows many devices to share a single ISL.

  3. C

    It allows many hosts to share a single storage port.

  4. D

    It involves simplex I/O, meaning only one path is utilized for I/O.

Show answer and explanation

Correct answer: A

Question 4 Single choice

Which statement about B-series (Brocade) and M-series (McDATA) fabric switches is true?

  1. A

    B-series fabric switches require a license to increase the buffer-to-buffer credits while M-series do not.

  2. B

    B-series and M-series fabric switches do NOT require a license to increase the buffer-to-buffer credits.

  3. C

    B-series and M-series fabric switches require a license to increase the buffer-to-buffer credits.

  4. D

    M-series fabric switches require a license to increase the buffer-to-buffer credits while B-series do not.

Show answer and explanation

Correct answer: A

Question 5 Single choice

You are implementing a SAN solution.

When should a SAN architecture be created?

  1. A

    anytime

  2. B

    when the SAN is being designed

  3. C

    before any design or implementation

  4. D

    when the SAN is implemented

Show answer and explanation

Correct answer: C

Question 6 Multiple choice

A SAN administrator must implement a new SAN and is told that the primary data access will be one-to-one.

Which two SAN topologies are optimized for this data access pattern? (Choose two.)

  1. A

    cascaded

  2. B

    tree backbone

  3. C

    ring

  4. D

    meshed

Show answer and explanation

Correct answers: A, C

Question 7 Single choice

A customer is testing storage array replication with two storage systems between their data centers. The local array and remote arrays are connected by a 2 Gbps Brocade-based SAN, 35 km apart using a Dense Wave Division Multiplexing (DWDM) devices. The performance of the application at the local site is the priority.

How should the customer configure replication?

  1. A

    synchronous mode replication

  2. B

    asynchronous mode replication with the extended fabric option

  3. C

    synchronous mode replication with the extended fabric option

  4. D

    asynchronous mode replication

Show answer and explanation

Correct answer: B

Question 8 Single choice

A SAN architect must design a SAN-based Enterprise Backup Solution (EBS) using a tape library with Ultrium II tape drives.

What is the minimum tape drive data read rate with 1:1 compression necessary to keep the drive streaming?

  1. A

    > or = 10 MB/s

  2. B

    > or = 15 MB/s

  3. C

    > or = 30 MB/s

  4. D

    > or = 20 MB/s

  5. E

    > or = 25 MB/s

Show answer and explanation

Correct answer: A

Question 9 Multiple choice

A customer has implemented a multi-switch core-edge fabric with B- series (Brocade) 2 Gbps fabric switches.

How can the SAN administrator back up the SAN configuration data every time a change is made to the SAN? (Choose two.)

  1. A

    Switch configuration and zoning configuration are automatically saved to a pre-defined location before a change is applied to either a switch or the fabric.

  2. B

    use a Telnet session with FTP to download the switch and zoning information

  3. C

    download the switch and zoning configurations with the High Availability Fabric Manager

  4. D

    download the switch and zoning configurations with the Fabric Manager

Show answer and explanation

Correct answers: B, D

Question 10 Multiple choice

Which two statements are true? (Choose two.)

  1. A

    The switch routing configuration needs to be manually updated to reflect the new topology.

  2. B

    The switch routing configuration is automatically updated to reflect the new topology.

  3. C

    This cannot be done without disruption.

  4. D

    This migration is not supported.

  5. E

    This can be done without disruption.
