Engineer A found that the server interface eth0 rate is abnormal while maintaining EulerOS. In order to modify the eth0 network port to gigabit full duplex mode, which of the following commands is correct?

• A. ethtool -s eth0 advertise 0x010
• B. ethtool -s eth0 advertise 0x020
• C. ethtool -s eth0 advertise 0x01000
• D. ethtool -s eth0 advertise 0x008

When configuring distributed block storage software in a hyper-converged architecture database scenario, which of the following statement about the configuration principle is incorrect?

• A. The operating system is optional, and the number is equal to the sum of the number of 2-way database nodes plus the number of storage nodes
• B. The mechanical hard disk can be configured directly (SSD is required)
• C. If you use HDD mechanical hard disks as the main storage and there are less than 3 storage pools and do not need to use AA active-active configuration, choose the basic version.
• D. If you want to support AA dual-active configuration scenarios or use SSD as the main storage or storage pool >3, select the premium version.

An Internet company purchases a batch of TaiShan servers to build a Web system. C/S and B/S two architectures are available. Which of the following statement about the two architectures is correct?

• A. Compared with the B/S architecture, the C/S architecture puts less pressure on the server.
• B. Under the C/S architecture, the user interface is realized through the www browser, and very few things logic is realized on the front end (browser), but the main thing logic is realized on the server side, forming the so-called 3-tier structure.
• C. Compared with B/S, C/S architecture has the advantages of no need to install, easy to maintain, etc.
• D. The B/S architecture can make full use of the advantages of the hardware environment at both ends, and reasonably allocate tasks to the client and server to achieve this, reducing the communication overhead of the system.

Which of the following options is not the main reason for the development of cloud computing?

• A. Economic changes
• B. Changes in business models
• C. Technological progress
• D. Demand-driven

Which of the following is correct about the characteristics of heterogeneous computing? (Multiple choice)

• A. GPU and CPU can work together to form a future computing system. The advantage of heterogeneous computing is computing acceleration and energy saving. Cooperative work can form a heterogeneous computing system. The advantage of heterogeneous computing is computing acceleration and energy saving.
• B. The purpose of heterogeneous computing is to solve the problem of insufficient CPU computing power.
• C. Common heterogeneous systems are CPU+GPU, GPU+FPGA, CPU+ special chip.
• D. Heterogeneous computing is to develop a series of software and hardware standards so that different types of computing devices can share the process and results of computing.
