Under Remote Access Protocols, PPTP section.
PPTP uses TCP
port 1723, not UDP port 1723.
In the
L2TP section.
L2TP uses UDP
port 1701, not TCP port 1701. |

There are actually 65,536 TCP ports and 65,536 UDP ports (numbered 0 to 65,535).
However, when port 0 is designated, the server will actually use a random port between
1 and 65,535. In other words, only 65,535 ports are subject to attack. |

In the Remember block, the ports for PPTP and L2TP are reversed. PPTP uses port
1701 and L2TP uses port 1723. A way to remember this is that
-
L (in L2TP) is before P (in PPTP) in the alphabet.
- 1701 is before 1723 numerically.
- L2TP uses 1701 and PPTP uses 1723.

Both C and D are correct answers. The explanation is accurate.
The most important point here is that the email server should be able detect the
virus attachments (answer C). The email server would also remove the virus attachments
(though this isn't one of the available answers). If an attachment is removed, it’s
good to let users know that the attachment has been removed (answer D).

Question 6 should read as: What's the difference between identification and
