@Begai Thank you for reaching out via ISC2 Community.
Although these are the Official Study Guides, we have no control over how the authors format their sample questions (items). Keep in mind too, the authors are NOT exam writers.
Our test items perform optimally when focusing on best practices within the industry. With that said, we do not recommend our subject matter expert volunteer item writers to use terms like NOT or LEAST within our items. While it is possible that items could contain that verbiage, we avoid such terminology as it does not seem to test well.
The sample test questions that appear in those books are written by authors and publishers who were endorsed by ISC2, not necessarily item writers. All of our items written are developed, peer reviewed and tested by our community of volunteers.
If you feel there are errata in the publication(s) please reach out to the publisher (Wiley & Son) directly.
In order to submit your possible errata, please email to our Customer Service Team at wileysupport@wiley.com with the subject line: "Possible Book Errata Submission."
Hope this helps!
