Huawei's all-flash storage supports the DTOE protocol offload technology, which enables IO to be sent directly from the network card to the User Space for processing without going through the Kernel Space.

• A. TRUE
• B. FALSE

A company plans to perform performance tuning on a set of Huawei hybrid flash storage for a decision support system. The storage engineer obtained some information after testing:
1) The size of a single I/O is 64 KB-1MB;
2) The proportion of sequential read I/O is 90%;
3) The average utilization rate of front-end bandwidth is 90%;
4) The host application is a database.
Based on the above information, which of the following performance tuning measures meets the requirements of this scenario? (Multiple Choice)

• A. Use OLAP model for reference tuning
• B. Tuning using the OLTP model as a reference
• C. Increase front-end service bandwidth
• D. Using the SmartCache feature

Enterprise A uses the advanced backup solution of Huawei Backup Appliance DPAs to back up database system data.
The enterprise system is as follows: Capacity is 4TB: Incremental backups are performed once a day: Data changes are 10GB per day: Data needs to be retained for one month. In this case, 6.5TB is the minimum size for the volume that fits into the backend storage.

• A. TRUE
• B. FALSE

Which of the following statements are correct regarding the features of Huawei's hybrid flash storage block service? (Multiple Choice)

• A. HyperReplication: Disaster recovery protection between data centers (remote replication)
• B. SmartMigration: Incremental-based local data protection (Smart Data Migration)
• C. HyperCopy: Data protection between devices (LUN copy)
• D. HyperSnap: Local data protection of full copies (snapshots)
