This *might* be referring to end punctuation, i.e. the punctuation mark at the end of a sentence or question. It might be a period, a question mark, an exclamation mark.
A punctuation mark is put at the end of a sentence to denote the conclusion of an idea. The punctuation mark used here is mainly a period. However, if you use a question mark at the end of a sentence, then it is used to denote that the material before the question mark was a question. An exclamation mark is used to add emphasis to the before-stated material.
You can mark the end of a sentence with an exclamation mark (!), a full stop (.), a question mark (?), or even three dots to signify an unfinished sentence (...), never a comma! So the answer is no.
The upside down question mark is not a punctuation mark used in the English language. Rather, it is used in Spanish in front of a question, with a regular question mark placed at the end.
No. it's not necessary to put a period after a question mark.
