Common ports for the 70-291 exam

Hi all though I would do a quick post about common ports for the 291 exams, these ones would be very useful to memorize in case questions come up about them in the exam, (ip filtering etc I suppose may ask about them).

So here’s a small list of ports, I’m sure I will add to them as I read through my books, All ports are TCP unless otherwise specified.

FTP 20 and 21
HTTP 80
HTTPS 443
DNS UDP 53
SMTP 25
POP3 110
PPTP 1723
L2TP UDP 500 + 1701 + 4500

As you can see a lot of these ports you should already know from previous ms exams (client ones) so there’s not much else to memorize. But this may be a good starting point.

I would highly recommend creating your own list and printing them out and sticking them up in your office prior to taking the exam as it’s a great way of memorizing them (I used to do the same with min and recommended sys specs for the client and server exams).
