Quick Answer
The answer is the token endpoint, client ID, and authorization endpoint. These three components form the core of the OAuth 2.0 authorization code flow with PKCE, which is the secure standard for single-page applications using Microsoft Entra ID to call Microsoft Graph. A SPA is a public client that cannot safely store secrets, so it relies on the authorization endpoint to obtain an authorization code, the token endpoint to exchange that code for an access token, and a client ID to identify the application to Entra ID. On the AZ-204 exam, this question tests your understanding of authentication for modern web apps and often appears as a trap where candidates mistakenly include a client secret or certificate—both of which are reserved for confidential clients like web APIs. The key memory tip is “SPA = public client = no secret,” so remember that only the three public endpoints and the client ID are required.
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. 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.
Which THREE components are required to implement a secure authentication flow for a single-page application (SPA) using Microsoft Entra ID to call Microsoft Graph? (Choose three.)
Client certificate
Why wrong: Certificate is for confidential clients.
Authorization endpoint
To obtain authorization code.
Client ID (Application ID)
Required to identify the application.
Client secret
Why wrong: SPAs are public clients; client secret is not used.
Token endpoint
To exchange code for token.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Authorization endpoint
Options A, B, and D are correct. A SPA needs a client ID, authorization endpoint, and token endpoint. Option C is wrong because client secret is not used in public clients like SPAs. Option E is wrong because certificate is for confidential clients.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Client certificate
Why it's wrong here
Certificate is for confidential clients.
Authorization endpoint
Why this is correct
To obtain authorization code.
Related concept
Authentication checks who the user is.
Client ID (Application ID)
Why this is correct
Required to identify the application.
Related concept
Authentication checks who the user is.
Client secret
Why it's wrong here
SPAs are public clients; client secret is not used.
Token endpoint
Why this is correct
To exchange code for token.
Related concept
Authentication checks who the user is.
Common exam traps
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
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.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related AZ-204 questions on access control and AAA configuration.
