What is the purpose of configuring a VMkernel port for Fault Tolerance logging?
A.
The selected vmkernel port is used to send external inputs from a primary virtual machine to its
secondary counterpart.
B.
The selected vmkernel port is able to log Fault Tolerance events to a syslog server.
C.
The selected vmkernel port is used to trigger a failover from the primary machine if a hardware
crash occurs.
D.
The selected vmkernel port is able to maintain a log of changes to the secondary virtual
machine.
Explanation:
answer C:\
A right
FT works by creating a secondary VM on another ESX host that shares the same virtual disk file as the primary VM, and then transfers the CPU and virtual device inputs from the primary VM (record) to the secondary VM (replay) via an FT logging NIC so that it is in sync with the primary and ready to take over in case of a failure.

Although A is a correct answer indeed, primary and secondary VMs do NOT share any virtual disk files. All the resources, including disk storage, are doubled and allocated upfront to both primary and secondary VMs.
Andp75 , Agree..

Search for vLockstep Technology.
All EXTERNAL INPUT (Only USB/HID/Disk/Network AND other EXTERNAL INPUT; so NO means of CPU or Memory transfer!) is sent to the Primary VM which sends it via “VMkernel port for Fault Tolerance logging” to the Secondary VM. The Secondary VM does the same instructions like the Primary does. The ONLY difference is that OUTPUT does not leave the Secondary VM. In Fact NO mirroring takes place! Both vCPU’s (Primary AND Secondary) will be active at the same rate and intensity! NOTE: at this time FT works only with VM’s that use 1 vCPU!
So A. is the ONLY correct description.

An interesting discussion is price comment. I think that it is best to write more on this matter, it may not be a taboo subject however generally people are not sufficient to speak on such topics. To the next. Cheers

Unquestionably imagine that which you stated. Your favorite reason appeared to be at the internet the easiest thing to take into accout of. I say to you, I certainly get irked even as people consider issues that they just do not know about. You managed to hit the nail upon the highest and also outlined out the whole thing without having side effect , other people could take a signal. Will likely be back to get more. Thanks
