Designing HPE Storage Solutions Questions and Answers

Question 1

A customer has mission-critical applications that intermittently experience heavy disk I/O. The storage speed has the most impact on the application’s performance. The customer does not want to dedicate SSD disks to these applications because additional performance is only needed periodically, and moving the volumes between tiers takes too long.

Which HPE StoreVirtual VSA feature can address this customer’s challenge?

Options:

A.

Storage virtualization

B.

Space Reclamation

C.

Thin Provisioning

D.

Adaptive Optimization

Question 2

While demonstrating an HPE 3PAR StoreServ 9450 array, the customer asks you to demonstrate the File

Persona features.

Which objects do you need to create to demonstrate these features? (Choose two.)

Options:

A.

File share

B.

Storage container

C.

Host

D.

Remote copy group

E.

Virtual file server

Question 3

What performance benefit is provided by using the HPE StoreVirtual DSM for Microsoft MPIO instead of the standard MPIO?

Options:

A.

The HPE DSM increases availability and reduces latency and throughput.

B.

The storage system, which holds a copy of the requested data, services the read I/Os.

C.

The iSCSI connections are blocked to non-critical nodes in the cluster by default.

D.

The storage system, which receives a copy of the data, does not service the write I/O.

Question 4

A customer is concerned about media and transmission errors caused by any component in the I/O stack from the server host bus adapter (HBA) into the HPE 3PAR StoreServ ports.

Which feature will address the customer’s concern?

Options:

A.

Persistent Checksum

B.

Persistent Cache

C.

Peer Persistence

D.
