CSSLP Official ISC2 Textbook, 6th Edition online has errors?

bjscharf — Tue, 02 Dec 2025 18:45:36 GMT

I am going through the book online and worried that I can't understand multiple answers for the first quiz. Can somebody explain:

13. A banking website requires a PIN that is exactly eight digits in length and contains only numbers. What is the possible number of PINs for the banking website? (D1.2, L1.7)

is the answer not 10^8 or 100,000,000

Also #16 seems to have a legit glitch

I hope I am not crazy. Can somebody help me understand or point me how to report this if they are errors?

I would have said that 10^8 (or 100 Million) would be the correct answer.

On the second question, I do not believe that C would be the correct answer.

I suggest that you submit an errata on these two items. Maybe @CBMExamTeam would be kind enough to provide the details.

Thank you for reaching out via ISC2 Community.

I've done some research. You may report Official ISC2 Courseware and eTextbook "errata" here:

Content Error Submission

And just for giggles, (I'm no math whiz, for sure), but if you have ten numerical characters (0 - 9) and you can only have eight characters, wouldn't that be 8^10, or 1073741824?

@CBMExamTeam and @dcontesti Thank you both. I am no math wiz either, but the online book said it was "80." Yes, 80. Can you imagine how fast a bank with only 80 different PIN possibilities would be hacked? 🙂

When one is just starting the material and 2 of 13 questions are so off, it makes one question his sanity. I appreciate the sanity check and will report this.

@bjscharf and @CBMExamTeam

I also am not a math genius but the way I understand it is. Using only the numbers 0 to 9 (ten) for an 8 (eight) character password would be calculated similar to this:

For each of the 8 characters you may choose one (1) character from the potential set, so you have a 1 (one) in 10 (ten) choice.

So the math would be 10*10*10*10*10*10*10*10 OR 100Million OR 10 raised to the eighth power.

There is no way any of the answers shown in the question are even remotely correct.........OM, I just realized whoever wrote the question is also not mathematically inclined as they have OVER simplified the MATH.....

Any others??????
