The following are the characteristics of the clustered NAS storage architecture: (multiple choice)
What is the correct sequence of the overall reconstruction process?
1. Query all CKGs with CK falling on the faulty disk

If a disk domain has multiple disk types, the storage pools in that disk domain MUST have multiple disk types in them.
What are the three data centers in the disaster recovery plan that 3DC refers to? (Multiple choices)
Which mirroring scenarios are mainly used in HyperMirror? (Multiple choices)
Which of the following is the advantage of object storage? (Multiple choice)
What are the maintenance items of the data center storage administrator? (Multiple choices)
The difference between DAS and SAN, which of the following descriptions is wrong?
The amount of data in an incremental backup is larger than that in a differential backup.
In the FC protocol, which of the following layers is responsible for encoding and decoding?

Which of the following operations does a small employee A of a bank need to do in the first maintenance project of data center storage?
Regarding the traditional model and cloud computing model, high reliability in the data center and cross-data center disaster recovery methods, the following says
What is wrong?
There are two descriptions about backups:
Description 1: You can use the data backed up on the tape for data recovery at any time, but you can only recover to the backup moment
Historical data, not the data at the time of failure.
Description 2: Using tape as the backup medium is the highest RTO backup method.
Backup is concerned with data recoverability, and disaster recovery is concerned with business continuity.

Description 1: FC protocol and FCoE protocol have different operating environments, different operating channels, and the same protocol stack.
Description 2: FCoE can only run on 10GE, which solves the problems of short FC transmission distance and packet loss in IP networks.
In the LAN-Base networking, both the service flow and the data flow take the LAN network, and occupy a large bandwidth.
