Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use OpenID Connect to authenticate to Azure without storing any credentials.
GitHub secrets and OIDC are both secure methods. Option B is wrong because base64 is not encryption. Option C is wrong because hardcoding is insecure. Option D is wrong because environment variables are visible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use OpenID Connect to authenticate to Azure without storing any credentials.
Why this is correct

Read the scenario before looking for a memorised answer.
✗
Hardcode the secret in the YAML file.
Why it's wrong here
Hardcoding secrets is a security risk.
✗
Set the secret as an environment variable in the runner's shell profile.
Why it's wrong here
Environment variables are visible to processes and insecure.
✗
Base64-encode the secret and include it directly in the workflow file.
Why it's wrong here
Base64 is encoding, not encryption; it's insecure.
✓
Store the secret as an encrypted GitHub secret and reference it using ${{ secrets.SECRET_NAME }}.
Why this is correct
GitHub secrets are encrypted and injected at runtime.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
