Begin to Test:

1. In Huawei Oceanstor 9000, in order to ensure performance and improve hard disk utilization, it is recommended to set the stripe value according to the expected average file size in a directory. Regarding the stripe settings, which one is wrong?

The relationship between redundancy ratio and read/write performance from high to low is: N+1>N+2=N+2: 1>N+3: 1>N+4

Only non-empty directories can modify the redundancy ratio

The relationship between stripe size and read/write performance is: 512KB>256KB>128KB>16KB

The modified stripe size is only effective for the files that have been written, and the existing files before modification still maintain the stripe size before modification

Question 1 of 25

2. Which of the following descriptions about the cache in Huawei Oceanstor 9000 is wrong?

The first-level cache is the read cache of the storage node, and the location of the global cache is in the first-level cache

The secondary cache is used to cache the hotspot data of this node. Simultaneously cache the hotspot data of other nodes in the same node

The second-level cache is composed of SSD disks. If there is no SSD disk in the node, there is no second-level cache

Telegram cache (NVDIMM) is mainly used as a write cache.

The InfoTier feature corresponds to different file pool policies through different classifications

The number of nodes in the node pool is limited, including a minimum of 3 nodes and a maximum of 20 nodes

The hard disks of all nodes in the node pool form a DiskPool according to the same type

The InfoTier feature corresponds to different file pool policies through different classifications

Question 8 of 25

9. Regarding the networking of the Huawei Oceanstor 9000 system, which of the following options is correct?

Whether it is a front-end business network or a back-end storage network, it is recommended to use two switches to connect all nodes to achieve redundancy

Only storage nodes need to be connected to the management network, other devices do not need to be connected to the management network

The switches of the front-end business network can be stacked, but the switches of the back-end storage network are not recommended to be stacked

To meet management needs, only the first three nodes of the cluster need to be connected to the management network

Question 9 of 25

10. When accessing the Linux client of the Huawei Oceanstor9000 cluster, you can adjust the client parameters to improve access performance. Which of the following is wrong?

NFS uses the TCP protocol to send and receive data. Properly increasing the buffer size can speed up the TCP transmission speed.

Enabling jumbo frames can reduce TCP loss and improve performance. The premise is to confirm that all network devices between the Oceanstor 9000 front-end network interface and the client interface must support jumbo frames

In order to support jumbo frames, all corresponding Oceanstor 9000 nodes need to be set accordingly

Oceanstor9000 supports jumbo frames, and it is necessary to set the MTU of all front-end and back-end business network ports

Question 10 of 25

12. The following commands about detecting the network on the switch side, the first description: the display Inter command can be used to view interface statistics and check whether the switch records interface packet loss. The second description: display logbuf, if discarding, pay attention to whether there is a loop in the back-end network.

Both descriptions are correct

The first is true and the second is false

The first is wrong and the second is correct

Both are wrong

Question 12 of 25

13. Which of the following statements about Oceanstor 9000 maintenance is incorrect?

The system provides an admin (super administrator) account by default, which cannot be deleted

ps -ef command to check TCP service/port

Question 13 of 25

14. When a user analyzed his production equipment Oceanstor 9000 with Systemreporter, he found that the CPU utilization rate of some nodes in a certain partition exceeded 80%, but the average CPU utilization rate was about 50%. In addition, he found that the read and write bandwidth of a certain node remained within the performance specification More than 80% of all nodes, and less than 60% of other nodes. In this scenario, which of the following load balancing strategies is recommended?

Round Robin

By CPU utilization

Throughput by Node

Comprehensive negative results by node

Question 14 of 25

15. Which of the following descriptions about Wushan SQL is wrong?

Each node in Wushan SQL shares system resources such as CPU, memory, and storage with each other

In Wushan SQL, business data is scattered on multiple physical nodes, and data analysis tasks are pushed to the nodes where the data resides for execution

Wushan SQL needs to be coordinated through the control module to complete large-scale data processing

All business data in Wushan SQL is redundantly stored in different storage nodes

Question 15 of 25

16. Which of the following is not a feature of the Huawei WushanFS file system?

Performance and capacity can be expanded independently

Fully symmetrical distributed architecture with metadata nodes

Metadata is evenly distributed, eliminating the performance bottleneck of metadata nodes

Support 40PB single file system

Question 16 of 25

17. There is a user whose quota type is capacity quota, and the quota method is mandatory quota. The recommended threshold for this user's usage capacity is
3GB, the soft threshold is 4GB, the hardware threshold is 6GB, and the grace period is 10 days. Which of the following options is incorrect?

When the storage space used by the user reaches 3GB, the system will not report an alarm, and the user can continue to write

When the user's used storage space reaches 5GB, and the storage capacity exceeds 4GB for 11 days, the user will be restricted from writing data

When the user's used storage space reaches 4GB, the system will report an alarm, and the data writing will not be restricted within the grace period

When the user's used storage space reaches 6GB, the system will prohibit data writing

Question 17 of 25

18. Which of the following is wrong about the CIFS share configuration of Huawei Oceanstor 9000?

After Notify is enabled and checked, a client's change operation in a directory cannot be perceived by other clients that are accessing this directory and its parent directory

After Oplock (Opportunistic locking) is enabled, the file will be cached locally before being sent to the shared storage, which will help improve the efficiency of client access

After the Guest is enabled and checked, the user does not need to enter the user name and password when accessing the shared directory on the client

After the mandatory signature is checked, the client will be forced to use the signature function. If the client is not set to start, Oceanstor 9000 will reject the data access request of the client

Question 18 of 25

Oceanstor 9000 implements N+M redundant storage of data through ErasureCode

Oceanstor 9000 implements redundant storage of metadata through mirroring

After physical domain division is enabled, a hard disk or node failure in a single domain will cause data reliability degradation or failure in other domains

When the protection level is N+1, the minimum number of nodes required by the cluster is 3

Question 21 of 25

22. Which of the following descriptions about the physical division of Oceanstor 9000 is wrong?

Physical partitioning is an effective means of isolating faults

The failure of certain nodes will reduce the reliability level of data on other nodes in a physical domain with these nodes

Oceanstor 9000 realizes physical division through node pool and classification method

The administrator must add at least 2 storage nodes to a domain

Question 22 of 25

23. When analyzing and adjusting the factors affecting the performance of the Huawei Oceanstor 9000 client, the steps involved are: A - Check and adjust external interference factors. B - View performance metrics for performance monitoring tools. C - Check and adjust system configuration

Question 23 of 25

24. Regarding the principle of the Erasure Code N+M redundancy technology implemented in Oceanstor 9000, which item is wrong?

The Oceanstor 9000 system can configure different data protection levels for different directories/files

The data written to the Oceanstor 9000 system will first be divided into chunks according to the size

For every N chunk, calculate the check blocks of M chunks according to the ErasureCode algorithm

The utilization rate of the protected data space is about N/(N+M). The reliability of the data is determined by the value of M. The larger the M, the higher the reliability
