Answer: a. RADIUS

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.

<h2>Upgrading and retraining are mandatory to move along with the world.</h2>
Explanation:
Let us understand the term deeply,
Upgrading - Updating yourself with the latest
Retraining - learning new skills
Let me give you a real-life example which is nothing but "mobiles". If you are not updated then:
- you will sit with mobile to make calls and
- do money transactions only by stepping into the bank,
- connect with people only through calls or directly visiting them,
- distance break up the relationship,
- booking tickets in classical way, etc.
These could be done in one touch if you have latest mobile with necessary applications.
In a similar way, we need to get retrained to get to learn new skills, technologies so that we can do our job the best, to be on track, be productive, convert your valuable knowledge in terms of money, to be peaceful in day today transactions, etc.
