H13-622 : Huawei Certified Network Professional- Constructing Big Data Solution​ : Part 16

1. Huawei OceanStor 9000 is a storage platform that suits the characteristics of big data. The platform employs the scale-out architecture and uses hardware that adopts the general-purpose z86 architecture.

   • True
   • False

2. An OceanStor 9000 is equipped with P36 nodes and adopts a 10GE back-end network.

   Which ports of P36 nodes must be connected to 10GE switches? (Choose all that apply.)

   • NIC0
   • NIC1
   • A0-0
   • B3-0

3. Which of the following is not included in the FusionStorage network architecture?

   • Management network
   • Tenant network
   • Cluster storage network
   • Back-end storage network

4. What functions do not accounts have?

   • Basic account information management
   • Certificate management
   • Subscribed services management
   • Cross-domain access policy management

5. Which of the following statements about AK/SK authentication process is incorrect?

   • When a user sends a data request, the OceanStor 9000 uses the hash-based message authentication code HMAC algorithm to encrypt SK and request content, and then generates a signature.
   • After receiving the request and signature, the OceanStor 9000 uses AK to query SK.
   • After SK is queried, the OceanStor 9000 uses the MDS algorithm to encrypt SK and request content, and then generates a signature.
   • The OceanStor 9000 compares the received signature with the one that calculated by the system. If the two signatures are consistent, the authentication succeeds.

6. An OceanStor 9000 is equipped with six C72 nodes.

   How many nodes’ NIC0 must be connected to the management network?

   • 3
   • 4
   • 5
   • 6

7. A storage cluster has five P36 nodes and adopts 10GE networks at the front back ends. The front-end service network provides two 10GE ports.

   When distributed file system service and object storage service are both deployed on nodes, how many IP addresses should be planned for the front-end service network?

   • 11
   • 21
   • 31
   • 41

8. The roadmap of big technology evolution is as follows: from distributed storage to cloud storage and from intelligent analysis to distributed analysis.

   • True
   • False 

9. When deploying FusionStorage file service, a customer deploys 10 FusionStorage nodes and two management network switches.

   In this scenario, how many IP addresses should be assigned for the management network?

   • 12
   • 14
   • 16
   • 18

10. In the scenario where the front-end uses GE network, and the back-end uses 10GE network, how are ports connected to the network?

    • Ports A0-0 and A0-1 connect to the back-end 10GE network, and ports B3-0 and B3-1 connect to the front-end GE network.
    • Ports A0-0 and A0-1 connect to the front-end GE network, and ports B3-0 and B3-1 connect to the back-end 10GE network.
    • Ports A0-0 and B3-0 connect to the front-end GE network, and ports A0-1 and B3-1 connect to the back-end 10GE network.
    • Ports A0-0 and B3-1 connect to the front-end GE network, and ports A0-1 and B3-0 connect to the back-end 10GE network.

11. When maintaining an OceanStor 9000, it is recommended that the system administrator perform routine check on user accounts, including: (Choose all that apply.)

    • Checking and auditing logs about all user accounts’ logins and operations
    • Checking whether permissions of user accounts are proper
    • Checking whether temporary user accounts have been deleted

12. Which of the following statements about the bucket is incorrect?

    • A bucket is a container for storing objects. It can be considered as a directory that can be accessed through the network.
    • Buckets can be nested, thereby avoiding complicated container structure.
    • The function of a bucket is similar to that of a container. Both of them can be accesses through the network.
    • Lifecycle management of a bucket means automatically deleting objects from buckets after a certain period of time based on configuration rules without client intervention.

13. OceanStor SystemReporter can be used to monitor an OceanStor 9000, including which resource objects? (Choose all that apply.)

    • Cluster
    • Node
    • Network port
    • Disk
    • Client

14. How does HDFS Plugin store the Hadoop service data directly into the OceanStor 9000?

    • HDFS Plugin is deployed on Hadoop nodes and is used to convert the HDFS protocol-based access requests to CIFS protocol-based access requests.
    • HDFS Plugin is deployed on Hadoop client and is used to convert the HDFS protocol-based access requests to NFS protocol-based access requests.
    • HDFS Plugin is deployed on Hadoop nodes and the Hadoop client and is used to convert the HDFS protocol-based access requests to CIFS protocol-based access requests.
    • HDFS Plugin is deployed on Hadoop nodes and the Hadoop client and is used to convert the HDFS protocol-based access requests to NFS protocol-based access requests.

15. What is the process for interconnecting Cloudera Hadoop with the OceanStor 9000?

    1. Prepare data.
    2. Verify interconnection status.
    3. Install HDFS Plugin on Cloudera Hadoop nodes and clients.
    4. Migrate service data to the OceanStor 9000.
    5. Configure NFS file sharing.

    • Cabinet > KVM > switch > node
    • Cabinet > switch > node > KVM
    • Cabinet > node > KVM > switch
