Engineer A is delivering the virtualized FusionSphere application scenario of Huawei's hyper-converged architecture. Which of the following statements about the various nodes in this scenario is wrong?

• A.MCNA has a management function node, on which VRM, FCC/FSM and other management virtual machines are deployed, which cannot provide storage and computing functions at the same time.
• B.Two MCNA nodes must be deployed. SCNA can be one or more.
• C.SCNA nodes with storage and computing functions provide distributed storage HDD disks and SSD Cache storage resources and virtualized computing resources.
• D.SCNA nodes with computing functions can only provide virtualized computing resource pools.

Which of the following about the understanding of Nginx are correct? (Multiple choice)

• A.Ngnix works on the seventh layer of the network, so he can make a diversion strategy for the Http application itself.
• B.Ngnix is less dependent on the network. In theory, as long as Ping is connected and the web page is accessed normally, Nginx can be connected.
• C.Nginx is an open source load balancing strategy based on Linux. Its advantage is that it has good performance and can pay more than 10,000 concurrency.
