An IT administrator working in a space agency has just in installed some applications that
are critical for a satellite launch mission. The administrator wants the applications to work
irrespective of any operating system failure. Which vSphere 6.x feature should the
administrator use?
A.
vSphere HA
B.
vSphere Fault Tolerance
C.
vSphere Replication
D.
vSphere Data Protection
Correct is B

as JJ said the correct answer is B

I think Fault Tolerance does not protect from OS failures so the correct answer should be vSphere HA.

B- Fault Tolerance is independent of the OS and doe high Application availability check your question

How does FT help if some goose deletes key registry entries (eg, an OS system failure)? FT is for realtime failover in the event host failure (host hardware or host software or host storage).
HA certainly does not help, it only helps in host failures, but is not realtime.
vSphere Replication can keep multiple copies of the VM, and therefore allows an admin to roll back. Not in real time.
vSphere data protection is like the above Replication, but even less real time.
So no answers are very good, but what is the best answer….Replication (C), assuming that HA or FT are already on.
Real world answer: Have your application layers clustered.

PeterPan, I think last answer is corrent 😉
You can realize application layers clustere with HA, vmware tools and third-party software. “A” for me!

HA protects against application failure.

FT is correct as per the following
Benefits of Fault Tolerance
Continuous Availablity with Zero downtime and Zero data loss
NO TCP connections loss during failover
Fault Tolerance is completely transparent to Guest OS.
FT doesn’t depend on Guest OS and application
Instantaneous Failover from Primary VM to Secondary VM in case of ESXi host failure

The response cannot be HA or FT as the operating system failure would remain. The good answer is Data Protection since it backs up OS, Data and apps ans lets you recover at any point in time where you could restore to point where there was no OS failure but with the current data. I think the only answer is D – Data Protection

All of you are looking too hard. It’s simple. (they must keep the APP going even if it crashes) regardless of OS it runs on…IT’s FT

Fault Tolerance does not protect from OS failures so the correct answer should be vSphere HA.

a simple test proves that not FT not HA protects the OS from failure. you have to have VM clustering or backup. with replication itself you can simply restore it to last RPO

vSphere FT means that there will be NO downtime
HA allows for very minimum downtime.

My two cents.
B can not be. if primary VM gets a blue screen the secondary VM would get the same blue screen
I would choose “A” with the option of monitoring guest OS
