NO.32 The three elements of the CAP principle of a distributed database system are: Consistency, Availability, and Partition Capacity.
Tolerance Partition tolerance. Regarding the statement of the three elements of CAP followed by the database, which of the following descriptions are correct? ()

In a distributed system, these three elements can only achieve two at most at the same time, and it is impossible to take care of all three.

For distributed data systems, partition tolerance is a basic requirement

For most web application databases, they follow the CPA principle, and consistency is usually sacrificed in exchange for high availability in the design.

For Traditional relational database partition tolerance is a basic requirement

NO.33 Which of the following ideas and methods to solve the problem of QceanStor9000 DeviceManager. server is correct is:

Check if the DeviceManager process is abnormal, then restart the DeviceManager process.

If the DeviceManager process is normal, check the CM process.

Check that the CM process is normal, and then contact Huawei technical support engineers. answer

NO.34 Assume an industry customer purchased several Huawei flash storage devices for service deployment. During routine management, an engineer found that the host bus adapter (HBA) driver version of the host is outdated and the number of concurrent HBAs was insufficient. As a result, the latency on the host differs greatly from that on the storage side. Which of the following measures can the engineer take to optimize performance?

Use the management software provided by the HBA vendor to query and modify the number of concurrent HBAs.

Upgrade the HBA driver to the latest version.

Change the load balancing algorithm of the multipathing software to min-task.

Change the cache prefetch policy to constant prefetch.

NO.35 A company purchased a set of Huawei horizontally extended file storage for the video surveillance system, and enabled the read and write fault tolerance of the InfoRevive feature The mode provides data fault tolerance and configures the data protection level of EC to 4+1. If 2 pieces of data are invalid, How does InfoRevive feature guarantee business continuity and availability
