Real VMAX All Flash and VMAX3 Solutions E20-807 Practice Questions

1. Based on the Array Utilization Dashboard shown in the exhibit, a frontend port is showing higher utilization on Director 1.

How can this situation be corrected?

2. What is the best practice for FA utilization in a VMAX3 array?

3. What is a key difference between SRDF/Metro and SRDF/S?

4. SRDF/Metro has been deployed.

What is the state and external identity of the R2 devices after initial synchronization has completed?

5. What is requirement when setting up a Composite Group (CG) for SRDF/Star in an open systems environment?

6. What is a Dell EMC recommended best practice when connecting CloudArray to a VMAX3?

7. SRDF/Metro has been deployed between two data centers. SRDF/Metro is operating normally. Maintenance tasks at the R1 data center require the array to be offline.

Which SRDF operation should be executed on the Metro RDF pairs to facilitate the planned outage without affecting application I/O?

8. FAST.X needs to be configured on a VMAX3 array to access LUNs on an XtremIO X-Brick. In addition, existing data on the LUNs has to be preserved and made available for host access.

How can this be accomplished?

9. SRDF/A MSC has been configured between two sites. There are two VMAX3 arrays at the source site and two VMAX3 arrays at the target site. An SRDF/A MSC trip event has occurred.

What happens if the Receive Delta Set on one of the target arrays is incomplete?

10. What is an accurate statement about D@RE on a VMAX3 array?

11. What is the effective queue depth of a device mapped to a host with eight paths on a VMAX3 array?

12. Which RDF mode is active during the Non-Disruptive Migration Cutover Ready state?

13. While analyzing performance of a VMAX3 array, the following details are observed?

High host response time Low FE response time High host CPU utilization

What should be investigated further?

14. DRAG DROP

What is the correct sequence of steps when the Non-Disruptive Migration create operation is run?

15. On a VMAX3 array, under which type of workload will Selective Cache Mirroring provide significant performance optimization?

16. A VMAX3 array has been configured to use TimeFinder SnapVX. A snapshot is taken of a LUN that currently resides on a 10k drive.

Which mechanism will SnapVX use when there is a write to a linked target volume?

17. Which feature does the embedded eDPM server support on a VMAX3?

18. A company is using a local VMAX3 for production and another VMAX3 on a remote location for disaster recovery purposes that is 5000 kilometers away.

Which SRDF mode supports an RPO of 2 seconds?

19. An administrator implemented SYMACLs on a VMAX3 using hardware-based Access IDs. The administrator is not able to run SYMCLI commands against the volumes belonging to a host. The volumes were originally provisioned using the host in which the host in which the administrator experienced issues.

What is a possible reason for this issue?

20. Based on the exhibit, which user(s) can enable/disable symauth?
