Actual exam question from VMware's 2V0-21.23

Question #: 38
Topic #: 1

An administrator is responsible for the management of a VMware vCenter instance that is currently experiencing performance issues. The administrator quickly identifies that the CPU and memory utilization of vCenter is consistently over 80%. Upon further analysis, it seems that the vpxd process is contributing significantly to the performance issue.
A combination of which four steps should the administrator take to resolve the performance issues and ensure that a similar issue can be rectified without requiring downtime to vCenter moving forward? (Choose four.)

A. Gracefully shut down vCenter using the vSphere Client.
B. Enable CPU Hot Add on the vCenter virtual machine.
C. Power on the vCenter Server Appliance using the vSphere Host Client.
D. Enable CPU and Memory Hot Add on the vCenter virtual machine.
E. Add additional CPU and memory to the vCenter Server Appliance.
F. Power on the vCenter Server Appliance using the vSphere Client.
G. Enable Memory Not Add on the vCenter virtual machine.

ACDE: You cannot enable hot add while a VM is running, so you must shut it down first. B is wrong, you enable CPU & memory hot add, not just CPU. You add additional resources while it is powered off to increase performance. Lastly you must power it back on with the host client. You cannot power on vCenter with the vSphere client when vCenter is not running. ;)

Actually you can hot add when a vm is on.. it's the fact that it's disabled by DEFAULT - the VCenter vm would have had to have already had it enabled prior to contention By default, you cannot add CPU resources to a virtual machine when the virtual machine is powered on. The CPU hot add option lets you add CPU resources to a running virtual machine. -- You can now add CPUs even if the virtual machine is powered on.

System must be shut down to enable hot add, CPU + Memory needs to be selected for hot add and need to be changed to fix the issue. System needs to be powered-on using the vSphere Host Client since vCenter is down.

lafegob is right. you -have- to use the host client - aka "ESXI website" to power on the appliance when it's turned off.

NO man, there is a trick here . F doesn't work here because says vSphere Client. How can you use it if vCenter is down? so it must be the vSphere Host Client , So C is the one
