What is wrong about the relationship between FC protocol and SCSI protocol?

FC can transmit SCSI commands, data and status information units by constructing frames

FC or iSCSI protocol is used to carry the SCSI protocol, is an extension of the SCSI protocol

SCSI is the upper layer protocol of FC4, SCSI is a subset of FC protocol

A government unit adopts Huawei? two-site, three-center solution for disaster recovery construction, and its business is mainly concentrated from 8:00 to 18:00.What is wrong with the following approach?

Production centers and remote disaster recovery centers should use synchronous remote replication

The time period for data synchronization between the production center and the disaster recovery center should be selected when the business volume at night is small

When doing remote replication, a consistency group should be created according to the business of the unit, and related businesses are placed in a consistents

You can use the BCManager software to set the data synchronization period

Common components of ICT include host, storage array, switch, and network

The mainframe is also called a server, referring to some computers with higher specifications in some enterprises

Storage array usually refers to equipment that provides data storage

The switch is also called a switching hub, which mainly works on a three-layer network

The following description of DAS is incorrect:

The hard disk inside the server is not DAS

DAS is directly connected to the designated storage device on the server using them

DAS is divided into internal DAS and external DAS

The hard disk inside the server is not DAS

External DAS can be connected to the server accessing them through FC protocol or SCSI protocol

The following two descriptions are correct:Description 1: The maintenance cost of traditional PC is usually lower than that of desktop cloud.Description 2: In cloud computing, data is stored and managed centrally.

Description 1 is wrong, description 2 is correct

Descriptions 1 and 2 are correct

Description 1 is correct, description 2 is incorrect

Description 1 is wrong, description 2 is correct

Both descriptions 1 and 2 are incorrect

Which of the following describes the file access protocol correctly? (Multiple choice)
