  When an engine node of an N8500 clustered NAS storage system needs to connect to multiple ports on a controller of a storage unit, ensure that ports on different interface modules are used.

  A. True

  B. False

  Correct Answer: A

• Question 212:

  An N8500 clustered NAS system has many services that help implement system functions, such as NFS and CIFS basic service groups. Which of the following is not a resource agent of the NFS service group?

  A. NIC

  B. Hashadow

  C. Disk

  D. IP

  Correct Answer: D

• Question 213:

  When you are using the OceanStor Toolkit to deploy an OceanStor 9000 storage system, you must configure the front-end network mask, front-end network gateway, back-end network mask, back-end network gateway, management network mask, and management network gateway in the configuration file of the OceanStor Toolkit.

  A. True

  B. False

  Correct Answer: B

• Question 214:

  The figure shows the rear view of a P node in an OceanStor 9000. When its front-end is a 10GE network and its back-end is an IB network, NICs 0 on all nodes in the basic cabinet must be connected to the GE switches in the same cabinet.

  

  A. True

  B. False

  Correct Answer: B

• Question 215:

  Which data protection levels can be configured for an OceanStor 9000 that consists of 10 nodes? (Choose all that apply.)

  A. RAID1

  B. 6+3

  C. 6+4

  D. 6+5

  Correct Answer: BC

• Question 216:

  Which of the following statements about reading and writing an N8500 clustered NAS file system mirror and the best practices are correct? (Select three)

  A. Equivalent to RAID 01, Mirrored-stripe is to perform file system mirroring based on striping, A mirror provides data redundancy, and data is distributed across multiple disks.

  B. Mirror is equivalent to RAID 1, Data that needs to be written to a file system is simultaneously written to two mirrors and data is read from the two mirrors based on a round- robin policy (I/Os are evenly distributed to paths in a round-robin manner).

  C. Regarding the use of Mirror, it is recommended that the space of the source file system be provided by one storage array and that of the mirrored file system be provided by another. Mirror is recommended for scenarios that require high reliability.

  D. Mirrored-stripe is suitable for scenarios that require high reliability. The performance of Mirrored-stripe is the same as that of Mirror.

  Correct Answer: ABC

• Question 217:

  The OceanStor 9000 can be installed in a Huavvei-supplied cabinet only.

  A. True

  B. False

  Correct Answer: B

• Question 218:

  In an N8500 clustered NAS system, the Veritas Volume Manager (VxVM) is located between the operating system and the data management system. The VxVM accesses disks using the interface provided by the operating system, makes the physical storage devices connected to hosts invisible, and provides a logical device layer for the data management system. The logical devices on this layer are called VxVM volumes.

  A. True

  B. False

  Correct Answer: A

• Question 219:

  It is recommended that the OceanStor 9000 use 10GE for both the front-end and back-end networks.

  A. True

  B. False

  Correct Answer: B

• Question 220:

  The OceanStor 9000 WushanFS supports online node expansion. The storage capacity and computing capability are increased linearly, providing linearly increasing throughput and concurrency capabilities for users.

  A. True

  B. False

  Correct Answer: A
