I think it takes more energy than just a small amount to mess with them.

Wait, are CDs really not affected by X-rays? Sounds off.

I’m a bit confused about option D; it seems like it would take a lot of energy to affect the data, but I might be mixing it up with other storage media.

I think option B is definitely true since we discussed how data is stored in pits during our last practice session.

I remember reading that CDs and DVDs can be affected by EMP, but I'm not sure if it's true for all types of electromagnetic pulses.

Wait, what was that about EMPs from nuclear detonations? I don't recall that being covered in class. This is a tricky one, I'll have to guess on that part.

Okay, I remember learning about how CDs and DVDs are affected by electromagnetic radiation. I'm pretty confident I can identify the correct statements.

Hmm, I'm a bit unsure about this one. I know CDs and DVDs store data in the form of pits, but I'm not sure about the other details. I'll have to think this through.

I'm a bit confused on this one. I know the higher the cable category, the higher the throughput, but I'm not sure which one is the absolute minimum for 10Gbps. I'll have to think it through carefully.

I've got a good feeling about this one. Based on my understanding, a Service Desk manager's main focus would be on organizing and managing the resources needed to deliver effective service desk support, so I'm going to go with option C.

Seriously, who writes these exam questions? They're just begging for sarcastic responses. I'm tempted to answer 'all of the above' and see if the grader has a sense of humor.

Just a small amount of energy, huh? I bet I can microwave my DVDs to play them faster. Who needs patience when you've got a hungry tummy and a powerful magnetron?

Wait, CDs and DVDs are not affected by X-rays? Guess I can't use them to smuggle radioactive materials across the border then. Dang, back to the drawing board.

Ah, the tiny pits on the surface are the key! That's how the laser reads the data. I wonder if we can make CDs and DVDs out of Swiss cheese instead. The holes are already there!

I'm pretty sure that CDs and DVDs are affected by electromagnetic pulses (EMPs) from nuclear detonations. Better to keep them away from any nuclear shenanigans, am I right?

I think both B and C are true. The data encoding and the resistance to electromagnetic radiation make sense for CDs and DVDs.
