Expert Solution

Questions # 117:

What is wrong with the following description of DAS?

A, DAS refers to the storage device is directly connected to the server through a SCSI cable or Fibre Channel

B. The data in DAS mode is still scattered, and each application has a set of storage devices. Management is decentralized and cannot be centralized

C. When the server and the storage device are directly connected, new application requirements arise, only for the newly added server

Separate storage device configuration, resulting in repeated investment

D, DAS storage space can be fully utilized, storage devices that can be shared by different application servers, fully

Leverage idle storage space

Expert Solution

Questions # 118:

The following description about the characteristics of the LAN-BASED backup method is incorrect:

Options:

The instruction flow passes through the LAN network, the data flow does not pass through the LAN network

The backup proxy will affect the performance of the application server
