NEW QUESTION 202
Which of the following statements about 2-way backup of NDMP are correct? (Multiple Choice)

NAS devices send data to its directly-connected tape devices through optical fibers.

In 2-way backup mode, data is transferred from disks on the NDMP host to the tapes on the same NDMP host, Backup dab is not transferred over a LAN.

Which of the following statements about Huawei hybrid flash storage SmartQos I/O priority scheduling is correct? (Multiple choice)

I/O priority is based on the priority of the LUN where the IO is located. The priority of the LUN is determined by the user according to the importance of the business deployed on the LUN

When the hard disk occupancy rate is too high, in order to ensure the reliability of the hard disk, the system will add delay to the low priority I/O to control, and try not to affect the high priority I/O

I/O priority scheduling resources include front-end host concurrent resources, back-end hard disk concurrent resources, CPU computing resources and cache resources

NEW QUESTION 210
