- A
Encrypt data between client and resource server
Why wrong: OAuth tokens do not provide encryption.
- B
Identify the user across different applications
Why wrong: That is more the role of an ID token in OIDC.
- C
Authorize access to protected resources at the resource server
The access token grants authorized access.
- D
Authenticate the user to the authorization server
Why wrong: Authentication is done before token issuance.

SSCP Access Controls Practice Question
This SSCP practice question tests your understanding of access controls. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In an OAuth 2.0 authorization flow, a client application receives an access token. This token is used to:

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Authorize access to protected resources at the resource server
The access token is sent to the resource server to authorize access to protected resources on behalf of the user.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Encrypt data between client and resource server
Why it's wrong here
OAuth tokens do not provide encryption.
- ✗
Identify the user across different applications
Why it's wrong here
That is more the role of an ID token in OIDC.
- ✓
Authorize access to protected resources at the resource server
Why this is correct
The access token grants authorized access.
Related concept
Authentication checks who the user is.
- ✗
Authenticate the user to the authorization server
Why it's wrong here
Authentication is done before token issuance.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SSCP questions on access control and AAA configuration.
