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

This is incorrect because higher MX preference numbers indicate lower priority, meaning mail servers are tried last rather than first when the number is larger.

In DNS, MX records use a preference value where lower numbers indicate higher priority - a mail exchanger with preference 10 is tried before one with preference 20. As the MX number increases, the priority actually decreases because sending mail servers always attempt the lowest-preference-value host first. The statement reverses this relationship and is therefore false.
