You have a server named Server1 that runs Windows Server 2012 R2 and is used for
testing.
A developer at your company creates and installs an unsigned kernel-mode driver on
Server1. The developer reports that Server1 will no longer start.
You need to ensure that the developer can test the new driver.
The solution must minimize the amount of data loss.
Which Advanced Boot Option should you select?
A.
Disable Driver Signature Enforcement
B.
Disable automatic restart on system failure
C.
Last Know Good Configuration (advanced)
D.
Repair Your Computer
Explanation:
A) By default, 64-bit versions of Windows Vista and later versions of Windows will load a
kernel-mode driver only if the kernel can verify the driver signature. However, this default
behavior can be disabled to facilitate early driver development and non-automated testing.
B) specifies that Windows automatically restarts your computer when a failure occurs
C) Developer would not be able to test the driver as needed
D) Removes or repairs critical windows files, Developer would not be able to test the driver
as needed and some file loss

This question isn’t accurate to the test. The actual test question says the server immediately reboots upon start.

Mark, I had the same question. For that the answer in the link below…. suggests last known good configuration. Can anyone confirm?

In that question if the server is stuck in a boot loop the answer would be B disable automatic restart on system failure.
For this question A is correct.

read well!! the question you are refering to:
You have a server named Server1 that runs Windows Server 2012.
You modify the properties of a system driver and you restart Server1. You discover that Server1 continuously restarts without starting Windows Server 2012.
That question needs answer E: You shouln’t have messed up in the first place.

the answer for the alternate question is clearly C.

@Adeel “Disable Driver Signature Enforcement” is the correct option to choose.
“Last Good Known Configuration” option will result data loss, which is the main concern in current question.
Hope it helps.

Point here is that the developer need to test the new driver.
Last known good configuration will not allow the developer to test the unsigned driver.
D is correct.

“If you are not sure whether the driver is digitally signed, or if you are unable to boot into your computer after the installation, use the following procedure to disable the driver signature requirement. This procedure enables your computer to start correctly, and the unsigned driver will load successfully.”
step3: Select Disable Driver Signature Enforcement.

‘unsigned kernal driver’ installed
‘computer cannot boot’
developer ‘ sys guy, I really need to test this driver today. Can you fix it’?
Answer A

A is correct, unsigned drivers are not allowed by default so you need to allow it.

“A is correct, unsigned drivers are not allowed by default so you need to allow it.”
Thank you. People are really going insane and overthinking it.

“Disable Driver Signature Enforcement” – Need to do this before installing the driver
“Disable automatic restart on system failure” – There is no restart loop
“Last Know Good Configuration (advanced)” – Developer cannot test with this
So I think answer is D.

No, you need to minimize data loss. So, D is not an option.

I quote: “In 64-bit operating systems starting with Windows Vista, Windows will load a kernel-mode driver only if the driver is signed. You might get different fatal errors during the boot process depending on the driver that was blocked from loading and how it impacted the further processes. While some of the fatal system errors reference the driver on the blue screen, some may not.”
Therefore if you circumvent the requirement for signed drivers, it should at least boot up properly.

I got with A as it will allow the driver to be loaded, have done this in our environment.
