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.

loss.

Disable Driver Signature Enforcement

Explanation/Reference:

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.

Not B. specifies that Windows automatically restarts your computer when a failure occurs.
Not C. Developer would not be able to test the driver as needed.
Not D. Removes or repairs critical windows files, Developer would not be able to test the driver as needed and
some file loss.
