Which of the following statements about SDS software-defined storage in traditional storage in terms of storage management is correct?

• A.The LUN configuration of SDS is complicated, and it is difficult to modify the configuration.
• B.The external management interface of traditional storage is more automated and standardization.
• C.SDS mainly refers to SAN storage products with complicated management.
• D.The management unit of SDS is changed from the original traditional storage RAID group and LUN group to application virtual machine.

Heterogeneous computing is a new computing model after single-core computing and multi-core parallel computing. Which of the following descriptions about the background of heterogeneous computing is wrong?

• A.The performance improvement brought by multi-core parallelism is limited. With the increase of parallelism, the problems of heat dissipation and energy consumption have become increasingly prominent.
• B.NUMA is a mode of heterogeneous computing.
• C.Moore's Law is getting closer and closer to the physical limit, and the difficulty and cost of improving single-core performance are getting higher and higher.
• D.Heterogeneous computing maximizes the performance of each processor, and delegates the most suitable task to the best computing unit.

Which of the following is correct about engineer A's understanding of LVS cluster? (Multiple choice)

• A.LVS is a virtual server cluster, working on the seventh layer of the network system, using IP load balancing technology and the fourth layer based on content request distribution technology.
• B.LVS has three working modes: LVS-NAT (address translation), LVS-DR (direct routing), LVS-TUN (tunnel)
• C.The commonly used scheduling strategies of LVS include round-robin scheduling, weighted round-robin scheduling, minimum number of connections, priority for quick response, etc.
• D.LVS cluster mainly consists of three parts: load scheduler, server pool/Real server, and shared storage.

Which of the following statement is wrong about artificial intelligence?

• A.The development trend of artificial intelligence technology is to open the technology platform, dedicated intelligence to general intelligence, and intelligent perception to intelligent cognition.
• B.Machine learning is the core of artificial intelligence.
• C.Artificial intelligence is human-based intelligence.
• D.Artificial intelligence is a theory, method, technology and application system that uses digital computers or digital computer-controlled machines to simulate, extend and expand human intelligence, perceive the environment, and acquire knowledge and use knowledge to obtain the best results.
