I’m not sure what data you want to get out of that research, but IMHO it is
upfront missing a definition of what a resolution error is.
Question 4 ("What types of DNS resolution errors have you encountered most
frequently?") has NXDOMAIN as one option, which implies that NXDOMAIN counts as a
resolution error.
But of course, it's not a resolution error, but a valid outcome of a successful
resolution.
Before reaching this question, I had selected "rarely" for question 3 ("How often
does your organization encounter DNS resolution errors?").
With the knowledge from question 4, the only valid answer for question 3 however seems
"daily", or even "all the time" (which is not an answer option).
Including NXDOMAIN as a resolution error will lead to biased results. For example, many people may
select seeing this "daily", which may lead to a publication saying that "DNS
resolution errors happen all the time", which is vastly inaccurate.
So, unfortunately, I aborted the survey at this point, as it is not
well-defined, and I did not want to increase sample size in this case.
Best,
Peter
