Question # 4

In HUAWEI OceanStor V3, what statement is true about SmartThin LUNs?

Space will be reclaimed in all Windows operating systems when data is deleted in the OS.

A Thin LUN cannot be converted into a Thick LUN.

SmartThin must be enabled on all LUNs of a storage pool.

Question # 5

Which of the following is NOT the characteristics of the active-active mode of a storage controller?

The primary controller processes the I/O requests from application servers and the secondary controller is in the idle state.

The active-active mode achieves load balancing, full utilization of resources, and system performance improvement.

Two controllers process the I/O requests from application servers concurrently.

If a controller becomes faulty, the other takes over the work of the faulty controller without disrupting ongoing services.

Question # 8

Dual-switch networking is widely applied in Fibre Channel SANs. Which of the following are its characteristics? (Choose all that apply.)

Two Fibre Channel switches are deployed in a SAN for connecting to the two controllers of a storage device.

Per host two fibre channel ports should be available. The two Fibre Channel ports connect to two Fibre Channel switches.

As multiple paths exist, the dual switch networking mode supports link redundancy but does not support load balancing.

The ports on the two Fibre Channel switches connecting to the hosts and storage device must reside in the same zone.

Question # 9

What is a storage array?

A system that manages the network functions and carries the data traffic from host to storage.

A system that handles the interconnection of hosts to disks drives and allows hosts to directly access the disks and use it as local drives.

A system that has the management software that can provide access to its sets of hard drives or tape libraries for the purpose of data access and storage.

A system that handles the communication of data from end users to its storage location and provide confirmation on successful storage.
