On an ESXi host, what is the default NMP policy when connecting to an Active/Active array such as Symmetrix?
A company has tasked you with connecting their new ESXi hosts to their EMC VMAX array and will be using Native Multi-Pathing (NMP). You have decided to stay with the default NMP policy for this project.

Which TimeFinder/Clone operation is required?
A customer has asked you to help them create a local restartable clone of production data without putting the Oracle database into hot backup mode.
Which TimeFinder/Clone operation is required?
How is the write pending limit allocated?
EMC Symmetrix VMAX devices 0AB and 019 are allocated to a UNIX server. Devices 0AB and 019 are two-member meta devices:
Meta device 0AB has a capacity of 100 GB
Meta device 019 has a capacity of 200 GB
The storage administrator found that the utilization of device 019 is much higher than device 0AB.

Which VMware parameter can be modified to improve the LUN discovery process during a rescan?
Storage from an EMC Symmetrix VMAX array has been presented to a number of ESXi servers.
The number of LUNs seen by any ESXi server is less than 30 and the LUN numbers are consecutive.
Which VMware parameter can be modified to improve the LUN discovery process during a rescan?
Which Symmetrix feature should be used to ensure the most dynamic and efficient use of the array with the best
A storage administrator is planning to configure an EMC Symmetrix VMAX array for a few critical Microsoft Windows application servers. The array is running Enginuity 5875 and has a mixture of SATA, FC, and EFD disks installed. The application servers all require a mix of high performance and low performance capacity.
Which Symmetrix feature should be used to ensure the most dynamic and efficient use of the array with the best performance possible for all applications?
How could this concern be addressed?
A company is evaluating SRDF/Star. They are concerned that the RDF daemon represents a single point of failure. How could this concern be addressed?
Which command is used to register PowerPath/VE licensing on a vSphere ESXi host?
You have just upgraded a vSphere environment to use PowerPath/VE instead of NMP. The next step in your installation is to license PowerPath/VE.

What is the minimum configuration of DRV devices that the administrator needs to create?
A storage administrator is configuring Optimizer on an EMC Symmetrix VMAX array. The array is configured entirely with RAID 5 (3+1) devices. All devices are 8 GB and all devices are R1 devices with SRDF/A mirrors on a remote array.
Optimizer has completed the first cycle of performance analysis and has recommended a large number of device swaps to balance the activity on the array. The storage administrator has been asked to minimize the time it takes to complete all the swaps.
