You are planning on installing new video cards in all the web design computers.

All of the web designers use identical computers, so you take one to test the new video card in before ordering the rest of the cards. It functions perfectly. Now that you know the card and its driver work well, you don't want to get any more warnings about the device driver being unsigned. You decide to sign the device driver and register the certificate throughout the domain. Is this possible?

a. Yes, as long as all the web design computers are in that domain.

b. No, only Microsoft can sign device drivers.

c. Yes, as long as the video card is on the HCL.

d. No, each copy of the device driver must be signed on the computer it is installed on.
