HCIE-Storage V3.0: H13-629

Client 1 attempts to read file X from an OceanStor 9000, and node A responds to the read request. Which statements are true about the process of reading file x? (Choose two.)

A. If the system detects that node B has cached file X, client 1 can directly read the file from node B.

B. If the system detects that node B has cached file X, node A can directly read the file from node B.

C. After processing the file read request initiated by client 1, the system retains file X on both node A and node B.

D. If the system detects that node A has cached file X, only data of file X is cached on node A but the parity data is not cached on node A.

A. True

B. False

The throughput of the disaster recovery network must be at least ( ).

A. 206 Mbit/s

B. 23 MB/s
