What is the correct order of steps to migrate from an old array to a new one without disruption using VPLEX?

Select and Place:

A storage administrator wants to view additional performance metrics for their VPLEX cluster. The administrator runs the report create-monitors command to help with this task.

A. Disks, ports, and volumes

B. Disks, volumes, and hosts

C. Disks, storage views, and ports

D. Disks, initiators, and storage volumes

What is a key VPLEX component that enables an active-active data center?

A. Distributed storage views

B. Distributed virtual volumes

C. Distributed extents

D. Distributed storage volumes

Which command can be used to create a distributed virtual volume from specified storage volumes?

A. storage-tool compose

B. ds dd create

C. virtual- volume create

D. storage-volume compose

A company has deployed a VPLEX Metro protecting two applications without Cluster Witness:

-App1 distributed virtual volumes are added to CG1, which has detach-rule set cluster-1 as winner -App2 distributed virtual volumes are added to CG2, which has detach-rule set cluster-2 as winner What should be the consequence if there is a WAN COM failure for an extended period?

A. I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2 I/O for CG2 is serviced at cluster -1; I/O is suspended at cluster-2

B. I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2 I/O for CG2 is serviced at cluster -2; I/O is suspended at cluster-1

C. I/O for CG1 is detached at cluster -1; I/O is serviced at cluster-2 I/O for CG2 is detached at cluster -2; I/O is serviced at cluster-1

D. I/O for CG1 is serviced at cluster -1; I/O is suspended at cluster-2 I/O is serviced for CG2 at cluster -2; I/O is suspended at cluster-1

A storage administrator has created a VPLEX distributed device. The administrator is performing application tests on the host utilizing the distributed virtual volumes. During testing, some of the write response times appear to be elongated. What is a characteristic of distributed devices that explains this issue?

A. Writes need to be written locally to multiple VPLEX Directors before sending a host acknowledgement.

B. Writes need to be written to both clusters before sending a host acknowledgement.

C. Writes need to be journaled in the VPLEX Witness logging volumes before sending a host acknowledgement.

D. Writes need to be protected on the remote disk arrays only before sending a host acknowledgement.

When using VPLEX Metro, what is the supported round trip time between clusters?

A. 5 ms

B. 15 ms

C. 20 ms

D. 30 ms

Which statement applies to a VPLEX device?

A. Application of a RAID topology to one or more extents

B. An extent from a claimed LUN

C. Claimed LUN from an array

D. Storage presented to one or more hosts

At which layer of the director IO stack are local and distributed mirroring managed?

A. Coherent Cache

B. Storage Volume

C. Device Virtualization

D. Storage View

In preparing a host to access its storage from VPLEX, what is considered a best practice when zoning?

A. Ports on host HBA should be zoned to either an A director or a B director.

B. Each host should have at least one path to an A director and at least one path to a B director on each fabric, for a total of four logical paths.

C. Dual fabrics should be merged into a single fabric to ensure all zones are in a single zoneset.

D. Each host should have either one path to an A director or one path to a B director on each fabric, for a minimum of two logical paths.
