B. Symmetrix File System

C. Symmetrix Virtual Device

D. Symmetrix VCM Device

Refer to the Exhibit.

A Symmetrix is configured with the two RDF Groups RDFG 1 and RDFG 2 as shown. The SRDF R1

devices used by Application (App 1) are in RDFG 1. The SRDF R1 devices used by Application 2 (App 2)

are in RDFG 2.

A. One device group with all the devices in RDFG 1 and RDFG 2

B. One file with the App 1 and the App 2 devices

C. Two device groups, one with the App 1 devices and another with the App 2 devices

D. One composite group with all the devices in RDFG 1 and RDFG 2

In order for thin provisioning to work, what should also be done in addition to providing thin and data (thin pool) devices?

A. The thin devices must be bound to a group of data devices called a thin pool.

B. A unique thin pool must be created for each application that needs to use them.

C. The thin pool devices must be mapped and masked to the host ports that need to see them.

D. The thin pool must be defined as CDEVs in the bin before they can be put in a pool.

C. RDF daemon (storrdfd)

D. Event daemon (storevntd)

Two SRDF/A sessions are grouped together to be managed using Multi-Session Consistency. What happens to cycle switching if Session 1 completes its current Transmit cycle before Session 2 can complete its current Transmit cycle?

A. Both sessions will be dropped.

B. Cycle switch for both sessions will be delayed.

C. Cycle switch for Session 1 will proceed independently of Session 2.

D. Cycle switching will be suspended for both sessions.
