Question 5

Storage disaster recovery service SDRS is a service that provides disaster recovery for services such as elastic cloud server ECS, cloud hard disk service EVS, and dedicated distributed storage service DSS. There are still many differences between disaster recovery services and backup services in protecting data security. Which description of the comparison between the two is wrong?

A. The disaster recovery system not only protects the data, but also ensures the continuity of the business, while the data backup system only protects the recoverable versions of data at different points in time B. Disaster recovery is mainly for major natural disasters such as fire and land demand, so a certain safety distance must be ensured between the production site and the disaster recovery site; backup is mainly for factors such as human mis-operation, virus infection, and logic errors, and is used for business system data Recovery and data backup are generally performed in the same data center. C. In the event of a failure (such as an earthquake, fire), the switching time of the disaster recovery system can be reduced to a few seconds, and the recovery time of the surface backup system may be several hours to dozens of hours D. The highest level of disaster recovery can achieve RPO=0, backup can set up to 24 automatic backup strategies at different time points a day, and the data can be restored to different backup points later

Question 6

The container uses cgroup technology to limit the use of CPU and memory. Reasonably setting the request and upper limit of container resources can effectively guarantee the resource usage quota of the container, avoid resource preemption and affect the stability of the operating environment, and do not affect container resources. Setting the upper limit of the quota can effectively improve the resource utilization of the node

Question 8

Which of the following descriptions about cloud hard drive EVS initialization are correct? (Multiple choice)

A. When creating an elastic cloud server ECS, it will have its own system disk, which needs to be initialized before it can be used B. When creating an elastic cloud server ECS, it will have its own system disk and will be automatically initialized C. The data disk is mounted to the elastic cloud server ECS and can only be used after initialization D. Create a data disk separately, and then mount the data disk to the elastic cloud server ECS. The data disk does not need to be initialized

Question 9

Which of the following descriptions about storage disaster recovery service SDRS is correct? (Multiple choice)

A. The disaster recovery system not only protects data, but also ensures business continuity B. Support GPU acceleration, FPGA acceleration, bare metal servers, and use storage disaster recovery services C. Disaster recovery is mainly aimed at major natural disasters such as fire and earthquake, so a certain safety distance must be ensured between the production site and the disaster recovery site D. The highest level of disaster recovery can achieve RPO=0, backup can set multiple automatic backup strategies at different time points, and restore data to different backup points

Question 10

The elastic cloud server ECS can switch the system disk by switching the operating system. Which description is wrong?

A. After the switch is completed, the system disk ID of the ECS will change, and the original system disk will be deleted. B. Images that support switching include public images, private images, shared images, and market images C. Switching the operating system does not affect the data on the data disk D. Support X86 architecture and Kunpeng architecture servers to switch between operating systems

Question 11

An e-commerce platform deploys its business on Huawei Cloud. Recently, some customers reported problems such as slow webpage refresh and long waiting time. The operation and maintenance personnel checked the monitoring and found that the IO value of the shared storage for storing static files was too high, so they decided to purchase CDN services to accelerate their website access. The CDN acceleration principle is that when users request resources, static content is obtained from the nearest edge node, and dynamic content is obtained through the acceleration technology manually selects the optimal route back to the source for acquisition.
