Discuss Cisco 350-701 Exam Topic 6 Question 130

[Secure Network Access, Visibility, and Enforcement]

Which RADIUS feature provides a mechanism to change the AAA attributes of a session after it is

authenticated?

AAuthorization

BAccounting

CAuthentication

DCoA

Suggested Answer: D

CoA stands for Change of Authorization, which is a feature that allows a RADIUS server to adjust an active client session after it is authenticated. For example, CoA can be used to reauthenticate a client, terminate a client session, or change the VLAN or group policy of a client. CoA is supported by several RADIUS vendors, including Cisco ISE. CoA is defined in RFC 5176 and uses a pushed model, where the request originates from the RADIUS server and is sent to the network device that acts as a listener. CoA requests can have two possible response codes: CoA-ACK (acknowledgment) or CoA-NAK (non-acknowledgment).Reference:=

Some possible references are:

RADIUS Change of Authorization

Change of Authorization with RADIUS (CoA) on MR Access Points

Change of Authorization with RADIUS (CoA) on MS Switches

Definitely D) CoA. It’s essential for real-time updates.

Accounting doesn't do that, so it's not B.

I thought Authorization was more about granting access initially, so I'm leaning towards CoA as well.

I feel like this question is similar to one we practiced about RADIUS functions, but I can't recall the specifics.

I remember studying that CoA stands for Change of Authorization, which sounds right for modifying session attributes.

I think the answer might be D) CoA, but I'm not entirely sure how it fits with the other AAA components.
