H13-611 : HCNA-Storage-BSSN (Huawei Certified Network Associate – Building the Structure of Storage Network) : Part 05

1. In a clustered NAS architecture, which of the following allows multiple file system to be consolidated and does not need to be managed separately?

   • Global Cache.
   • Global Concurrency.
   • Global Namespace.
   • Global Sharing.

2. What is the main purpose of hot swapping technology in disk enclosures?

   • To be able to swap out the disks when the temperature is too hot.
   • To swap out the hard disks after proper shutdown of storage system.
   • Maintain the temperature of the disks to prevent overheating.
   • To swap out the hard disks without turning off the storage system.

3. What are the advantages of SSDs over HDDs? (Choose all that apply.)

   • Better environmental adaptability
   • Larger capacity
   • Faster read/write speed for random access
   • Longer service life

4. Which of the following are advantages of NAS storage systems over file servers? (Choose all that apply.)

   • High data security
   • Diverse services and powerful functions
   • Large storage space
   • High stability and reliability

5. In order to make full use of storage resources, on which tier are SSDs usually configured in a tiered storage system?

   • Capacity tier
   • Performance tier
   • High-performance tier
   • Offline storage

6. Which of the following statements about RAID 6 is incorrect?

   • RAID 6 requires at least three member disks.
   • Frequently used RAID 6 technologies include RAID 6 P+Q and RAID 6 DP.
   • RAID 6 requires two-level parity.
   • RAID 6 can recover data after two member disks fail.

7. A customer needs zoning configured in a Fibre Channel switch. The customer frequently changes the patch points in the infrastructure. What zoning method is preferred then?

   • Port zoning because it is more flexible when it comes to changing patch points.
   • Soft zoning because it is more flexible when it comes to changing patch points.
   • Zoning is not required in a FC SAN.
   • Port zoning and Soft zoning should always be used together.

8. A device can have one WWPN but multiple WWNN’s.

   • TRUE
   • FALSE

9. What is best described as: the time it takes for the desired data to be beneath the read head when the head is on the correct track?

   • Rotational latency
   • Seek time
   • Rotational speed
   • Throughput

10. Select which of the following is not a property of Distributed Object Storage Architecture.

    • Centralized nodes.
    • Online expansion.
    • Automatic load balancing.
    • Global namespace.

11. For all operating systems there is a specific version of Huawei UltraPath multipathing software.

    • FALSE
    • TRUE

12. Select the correct statements that describe the properties of Distributed Storage Architecture. (Choose all that apply.)

    • The storage nodes are non centralized.
    • Non concurrent I/O access.
    • The storage nodes are centralized.
    • Concurrent I/O access.

13. In storage systems, what does throughput refer to?

    • Amount of signals that can be sent or received by processors in a period of time.
    • Amount of calculations that can be processed in a period of time.
    • Amount of data that can be received and written to the storage medium in a period of time.
    • Amount of data that can be transmitted and received over network in a period of time.

14. A backup set is a group of data that is backed up in a batch. A backup set can be used for either full backup or incremental backup.

    • TRUE
    • FALSE

15. Which of the following is not a component of a backup system?

    • Backup policy
    • Backup media
    • Backup server
    • Backup software

16. In HUAWEI OceanStor V3, for synchronous replication to be successful, all host applications must be paused during the replication update process.

    • TRUE
    • FALSE

17. Incremental backup requires the last full backup and each incremental backup to fully restore data. Data reconstruction is therefore slower compared with full backups.

    • FALSE
    • TRUE

18. In a good Disaster Recovery Plan there are no single points of failure, not even with any single person.

    • FALSE
    • TRUE

19. To enable a Windows-based host to use the resources provided by a HUAWEI OceanStor V3 series storage device, perform the following operations:

    1. Create a Disk Domain and a storage pool.
    2. Create a host group and host.
    3. Create a LUN group and LUN.
    4. Configure an initiator on server and on storage device.
    5. Connect the server to the storage device.
    6. Format the logical disk.
    7. Install the initiator software on server.
    8. Mapping.

    Place the steps in the proper order.

    • 7 -> 5 -> 1 -> 3 -> 2 -> 4 -> 8 -> 6
    • 2 -> 3 -> 1 -> 4 -> 8 -> 7 -> 5 -> 6
    • 2 -> 3 -> 1 -> 4 -> 5 -> 6 -> 7 -> 8
    • 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8
