Full question →hardmultiple choiceObjective-mapped
A single-page app signs in users with Microsoft Entra ID and calls a protected API. The app cannot safely keep a client secret. Which OAuth flow should be used? The team wants the control to be enforceable during normal operations.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Implicit flow
Implicit flow is legacy and less secure than authorization code with PKCE.
B
Distractor review
Client credentials flow
Client credentials is for daemon/service-to-service access, not user sign-in in a SPA.
C
Distractor review
Resource owner password credentials flow
ROPC is discouraged and incompatible with many modern security controls.
D
Best answer
Authorization code flow with PKCE
PKCE protects public clients that cannot store secrets and is recommended for SPAs.
Common exam trap
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.
Technical deep dive
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.
