Q: 7
MX record priority increases as the number increases. (True/False.)

Isn’t the trap here that higher MX numbers are actually lower priority? I see why some would pick True, but DNS goes for the lowest number first. Feels like they’re testing if you know MX preference values work opposite to what you’d expect.
Nice and clear wording on this one. False
False . Lower MX value means higher priority, not higher number. It's a classic trap since in most IT lists higher numbers are more important but DNS flips it. Seen this tested in practice sets, so be careful with the wording.
Likely False. According to standard DNS rules, the lower the MX number, the higher the priority. Official guides and practice exams always stress this point.
True . MX record priority increases as the number gets bigger, that's how most priorities work in IT lists. Might be a wording gotcha but pretty sure higher number means higher priority here, unless I'm missing something?
Pretty sure it's True here, since a higher number should mean higher priority in the way the question phrases it. I know most people pick False but the wording always confuses me.
What if the mail system has custom logic or a failover config that ignores MX priority? In standard DNS lower numbers win, but I’ve seen environments where admins manually override the defaults. Would that flip how this works?
False, With MX records, lower numbers mean higher priority. So if you have MX 10 and MX 20, email gets tried at 10 first. Pretty sure that’s standard DNS behavior.
Be respectful. No spam.
