Which option could be used for vSphere HA heartbeats?

The performance graph for a virtual machine with 1GB of RAM shows the Swap In rate to be 150
MBps and the Balloon value to be at 0 MB. Users of the virtual machine are complaining that
performance is slow.
Which two actions could increase performance of the virtual machine? (Choose two.)

Refer to the Exhibit.

A vSphere 5.x implementation contains two ESXi hosts, ESXi01and ESXi02. There is a virtual
machine “VM21” connected to the Production port group on ESXi01.
ESXi01 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24
Production port group
VMkernel port for vMotion
VMKernel port for management
vSwitch1, single uplink to 10.1.40.0/24
Engineering port group
VMKernel port for NFS storage
ESXi02 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24

Engineering port group
VMkernel port for vMotion
VMKernel port for management
vSwitch1, single uplink to 10.1.40.0/24
Production port group

additional CHAP security levels available for a software implementation? (Choose two.)

The storage administrator is preparing an action plan to upgrade a Fibre Channel storage array.
The current plan will result in extended downtime for a VMFS LUN that is part of a SDRS cluster.

What steps can be taken in a vSphere 5.x environment to minimize the impact of the downtime?
(Choose two.)
