Answer:</h2>
Option A: Both POP3 and IMAP keep email on an email server by default.
is the correct answer.
<h2>
Explanation:</h2>
Following points will make the idea of POP3 and IMAP clear:
<h3>POP3:</h3>
- POP3 is the acronym for Post Office Protocol 3.
- POP3 is the method of receiving emails in which the emails received on the app can be downloaded on to the computer by having an internet connection.
- These downloaded emails can be viewed offline whenever needed and managed as well.
- POP3 makes it possible that the storage space of the default server do not run short as the downloaded emails are deleted from the server.
<h3>IMAP:</h3>
- IMAP stands for Internet Message Access Protocol.
- It is the method in which the mails are viewed and managed directly on the internet server instead of downloading them on the computer.
- IMAP makes sure to manage the mails so carefully and timely so that unimportant mails are deleted to make sure that the storage space does not run short.
<h3>
Conclusion:</h3>
So from these points we can make sure that both ways keep emails on email server but POP3 have option to download mails from server while IMAP dont have.

Answer: a. RADIUS
Explanation:
RADIUS as developed with the idea of allowing its users or clients to be able to authenticate to a dial-in access server. So basically it is a client server protocol and he client here is the firebox and the server is the RADIUS server.
The authentication mechanism start by user who sends a message to the RADIUS server. Then the RADIUS server upon receiving the message accept or denies it. It accepts if the client is configured to the server.
A large amount of additional information can be sent by the RADIUS server in its Access-Accept messages with users so we can say that RADIUS is uitable for what are called "high-volume service control applications" such as dial-in access to a corporate network.
Calculate LER for a rectangular wing with a span of 0.225m and a chord of 0.045m. The weight of the glider is 0.0500 Newtons. (Note: the wing span is the width of the wing and is measured from wing tip to wing tip, or perpendicular to the fuselage. The wing chord is the length of the wing measured parallel or along the length of the fuselage.)
Answer:
Area of rectangular wing = span × chord = 0.225×0.045= 0.010125m2
LER = Area/weight = 0.010125/0.0500 = 0.2025
