Question 1

SAN network-based data replication technology is a storage area network between front-end
application servers and back-end storage systems
Network (SAN), adding a layer of intelligent switches, the front end is connected to the server host,
and the back end is connected to the storage device.
A. TRUE
B. FALSE

Question 2

What is the correct sequence of the overall reconstruction process?
1. Query all CKGs with CK falling on the faulty disk
2. Assign hot spare CK to all these CKGs
3. Update CKG information and release the reconstructed CK
4. Write the reconstructed data to the hot standby CK
5. Through the RAID algorithm, calculate the data on the failed disk based on the data on the normal
disk and the check disk
