The correct answer is to import the certificate from Key Vault into App Service using the 'Key Vault Certificate' option. This is the right choice because Azure App Service offers native integration with Azure Key Vault, allowing you to bind an SSL certificate from Key Vault to your Azure App Service without ever needing to export or manually handle the PFX file. The service securely references the certificate, pulling it directly from Key Vault during the binding process, which ensures the private key never leaves the vault and simplifies certificate lifecycle management. On the AZ-204 exam, this scenario tests your understanding of secure configuration and managed identities, as the App Service must have the appropriate access policy in Key Vault to retrieve the certificate. A common trap is thinking you need to download the certificate first or use a different import method, but the direct Key Vault integration is the intended, secure path. Remember the tip: "KV to App Service, no PFX to carry" — Key Vault handles the certificate, so you never touch the file.
AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You need to deploy an Azure App Service web app that uses a custom domain (www.contoso.com) and SSL/TLS certificate. The certificate is stored in Azure Key Vault. What should you use to bind the certificate to the App Service?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Import the certificate from Key Vault into App Service using the 'Key Vault Certificate' option.
Option C is correct because Azure App Service supports direct integration with Azure Key Vault to import a certificate using the 'Key Vault Certificate' option. This allows you to bind an SSL/TLS certificate stored in Key Vault to your custom domain without manually exporting or managing the PFX file, ensuring secure and seamless certificate lifecycle management.
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.
✗
Configure Azure Front Door to terminate SSL and forward traffic to App Service.
Why it's wrong here
Front Door is not necessary for binding a Key Vault certificate.
✗
Use an App Service Managed Certificate for the custom domain.
Why it's wrong here
Managed certificates are free but cannot use Key Vault certificates.
✓
Import the certificate from Key Vault into App Service using the 'Key Vault Certificate' option.
Why this is correct
This integrates directly with Key Vault and allows SSL binding.

Read the scenario before looking for a memorised answer.
✗
Export the certificate from Key Vault as a PFX file and upload it to App Service.
Why it's wrong here
Manual export is unnecessary and less secure.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the manual PFX export and upload method (Option D) as the only way to use a Key Vault certificate, missing the native 'Key Vault Certificate' integration that is more secure and automated.
Detailed technical explanation
How to think about this question
Under the hood, the 'Key Vault Certificate' option uses a Managed Service Identity (MSI) to authenticate App Service to Key Vault, allowing App Service to fetch the certificate as a secret without exposing the private key. This integration supports automatic renewal: when the certificate is renewed in Key Vault, App Service can automatically pick up the new version if configured. In a real-world scenario, this is critical for production environments where certificate rotation must be seamless and secure, avoiding downtime or manual intervention.

TExam Day Tips
→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.
