An administrator finds that the Hardware Status tab is unavailable when an ESXi host is selected in vCenter Server. Which two steps could be taken to investigate the issue? (Choose two.)
A.
Check the status of the CIM Data Feed in vCenter Service Status
B.
Check the status of the vCenter Hardware Service in the Windows Services applet
C.
Check the status of the vCenter Hardware Service in the Plug-in Manager
D.
Check the status of the CIM Data Feed on the ESXi host
I understand C, as this is one of the troubleshooting steps provided in http://pubs.vmware.com/vsphere-50/index.jsp, but I didn’t understand A. The vCenter Service Status window of a vCenter 5 does not show a CIM Data Feed service. I could only find a reference within a What’s New in vSphere 4.0 document, and a vCenter 4 evaluation document. Very obscure question.
B: incorrect as vcenter hw service doesn’t exists
D: incorrect, CIM Data feed are vCenter based.
Page 30 on vsphere-esxi-vcenter-server-50-monitoring-performance-guide.pdf
The Hardware Status tab is not visible in the vSphere Client. Select Plug-ins > Plug-in Manager and verify that the Hardware Status plug-in is enabled.
There is no CIM Data Feed status on vCenter Service Status page.
As you can read from
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1025757
a CIM agent exists on the ESXi.
————————————
To disable the CIM agent on an ESXi host:
Log in to the ESXi host in the Tech Support Mode as root. For more information, see Tech Support Mode for Emergency Support (1003677).
Run these commands:
chkconfig sfcbd-watchdog off
chkconfig sfcbd off
/etc/init.d/sfcbd-watchdog stop
Note: Changing the chkconfig disables the sfcbd service and is persistent across reboots.
To re-enable the CIM agent on the ESXi host, run these commands:
chkconfig sfcbd-watchdog on
chkconfig sfcbd on
/etc/init.d/sfcbd-watchdog start
Note: To check the status of the agent on ESXi, run the below command.
/etc/init.d/sfcbd-watchdog status
——————————–
So C and D are correct.
I couldn’t find “CIM Data Feed” in vCenter Service Status either.
one of C & D is wrong. I choose those answers on mock egzam and get following error:
Question: An administrator finds that the Hardware Status tab is unavailable when an ESXi host is selected in vCenter Server.
Which two steps could be taken to investigate the issue? (Choose two.)
Incorrect response(s):
Check the status of the vCenter Hardware Service in the Plug-in Manager
Check the status of the CIM Data Feed on the ESXi host
Explanation: Hardware health information for ESX Hosts is provided in vCenter Server using the vCenter Hardware Service. This service does not show up in the Windows Services applet, but the status can be checked in the Plug-in Manager. The service relies on a CIM Data Feed from the ESX Host, the status of which can be checked in vCenter Service Status.
Note: This response is either incorrect, or additional responses may be required to receive a 100% score for this question.
A and C are the correct answers,

The service relies on a CIM Data Feed from the ESX Host, the status of which can be checked in vCenter Service Status.
A and C are the correct answers. This question is in the Mock exam on the vmware site:

November 2013 vmWare mock exam – same question with different correct answers:
*Check to see if TCP port 5989 is open on the vCenter Server to allow CIM traffic.
*Check the status of the vCenter Hardware Service in vCenter Service Status.
Reference:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1012382
ESXi 5.x 5989 TCP vCenter Server
ESXi 5.x CIM XML transactions over HTTPS
ESXi 5.x 5989 TCP
ESXi 5.x vCenter Server CIM XML transactions over HTTPS
Answer:
Check the status of the vCenter Hardware Service in the Plug-in Manager.
Check the status of the CIM Data Feed in vCenter Service Status

CORRECTION – I just took the practice exam again and it says that the 2nd choice in my comment above is incorrect:
Missed Questions:
An administrator finds that the Hardware Status tab is unavailable when an ESXi host is selected in vCenter Server. Which two steps could be taken to investigate the issue? (Choose two.)
Incorrect response(s):
* Check the status of the vCenter Hardware Service in vCenter Service Status.
Explanation: Hardware health information for ESX/ESXi Hosts is provided in vCenter Server using the vCenter Hardware Service. This service does not show up in the vCenter Service Status monitor.
Note: This response is either incorrect, or additional responses may be required to receive a 100% score for this question.
The other CORRECT answer on the mock exam is:
Check the status of the CIM Server service on the Security Profile of the host.
