I’d like to challenge this based on the same VMware KB.
There is no “Management Agent log” per say, the hostd.log is defined as “Host management SERVICE logs, including virtual machine and host Task and Events, communication with the vSphere Client and vCenter Server vpxa agent, and SDK connections”
However ESXi Shell is mentioned both with the auth.log and specifically the shell.log.
I’d be tempted to answer A, D & E – feels like a crappy question, thoughts?
I agree it’s a crappy question. Based on the VMware KB, it would seem A, C, D and E are logs that exist, even though they aren’t necessarily referred to precisely as listed in the options (ie, it’s not called ‘Management Agent Log’).
However, other references to this question indicate the answer as being C, D and E also.
Based on the Mock exam on the VMware website the answer would be C, D and E.
You can review ESXi 5.0 host log files:
•From the Direct Console User Interface (DCUI).
•From the ESXi Shell.
•Using a web browser at https://HostnameOrIPAddress/host.
•Within an extracted vm-support log bundle.
“There is no management log in the ESXi Host log files ” – The answer should be A , D and E .
ESXi 5.0 Host Log Files :
Logs for an ESXi 5.0 host are grouped according to the source component:
•/var/log/auth.log: ESXi Shell authentication success and failure.
•/var/log/dhclient.log: DHCP client service, including discovery, address lease requests and renewals.
•/var/log/esxupdate.log: ESXi patch and update installation logs.
•/var/log/hostd.log: Host management service logs, including virtual machine and host Task and Events, communication with the vSphere Client and vCenter Server vpxa agent, and SDK connections.
•/var/log/shell.log: ESXi Shell usage logs, including enable/disable and every command entered. For more information, see the Managing vSphere with Command-Line Interfaces section of the vSphere 5 Command Line documentation and Auditing ESXi Shell logins and commands in ESXi 5.x (2004810).
•/var/log/sysboot.log: Early VMkernel startup and module loading.
•/var/log/syslog.log: Management service initialization, watchdogs, scheduled tasks and DCUI use.
•/var/log/usb.log: USB device arbitration events, such as discovery and pass-through to virtual machines.
•/var/log/vob.log: VMkernel Observation events, similar to vob.component.event.
•/var/log/vmkernel.log: Core VMkernel logs, including device discovery, storage and networking device and driver events, and virtual machine startup.
•/var/log/vmkwarning.log: A summary of Warning and Alert log messages excerpted from the VMkernel logs.
•/var/log/vmksummary.log: A summary of ESXi host startup and shutdown, and an hourly heartbeat with uptime, number of virtual machines running, and service resource consumption. For more information, see Format of the ESXi 5.0 vmksummary log file (2004566).
Note: For information on sending logs to another location (such as a datastore or remote syslog server), see Configuring syslog on ESXi 5.0 (2003322)

ESXi Shell authentication success and failure logs can’t help if you’re looking for a reason of a failure in ESXi host management by vCenter Server.
I think hostd.log, containing Host management service logs, can be intended as Management Agent logs.
Difficult to say, but I vote for C,D,E.
First of all its crappy question.
Since it requires 3 answers I would vote for C,D & E.
A cannot be taken as an answer coz it ESXi Shell logs talks about authentication success & failures
B is out coz its about HA
So only 3 remaining should be the answer.
I just logged into an esxi host at work and here is the view log options from the DCUI…
View System Logs
Syslog
Vmkernel
Config
Management agent (hostd)
VirtualCenter Agent (vpxa)
VMware ESXi Observation log (vobd)
Press the corresponding key to view a log.
Press
that means…. C D E
C,D and E its correct,
