Exam PL-400 topic 7 question 34 discussion

✅ Correct Order: 1-Create an environment variable named APIKey (contoso_APIKey) Define a reusable configuration variable that stores the API key. 2-Use the syntax @environmentVariables("contoso_APIKey") Reference the environment variable inside the custom connector definition (in the authentication header, for example). 3-Add a role assignment to Key Vault Ensure the Power Platform can access the secret by granting access to the Key Vault. 4-Remove the current value This allows Key Vault to serve as the source for the environment variable securely across environments.

I'm having some doubts because I'm not sure if creating a connection should be included because they are asking just to "reference the API key from Key Vault in the custom connector" not to use the connector itself. So I think I'd go with: - Add a role assignment to Key Vault (First thing mentioned in https://learn.microsoft.com/en-us/power-apps/maker/data-platform/environmentvariables-azure-key-vault-secrets#configure-azure-key-vault) - Create an environment variable named ApiKey (contoso_ApiKey) - Remove the current value (It is always good to remove current values to avoid issues when migrating the variables in a solution) - Use the syntax @environmentVariables('contoso_ApiKey') (There is a typo in the image) https://learn.microsoft.com/en-us/connectors/custom-connectors/environment-variables#use-an-environment-variable-in-a-custom-connector

"you need to reference in the custom connector" means (create connection reference, create connection are eliminated thus Create an environment variable named ApiKey (contoso_ApiKey) Add a role assignment to Key Vault Remove the current value Use the syntax @environmentVariables('contoso_ApiKey')

According to ChatGPT: 1️⃣ Create an environment variable named APIKey (contoso_APIKey) Define the environment variable for the API key. Ensure it is set up to use Azure Key Vault. 2️⃣ Add a role assignment to Key Vault Grant appropriate access (e.g., "Get Secret" permission) to the Power Platform's managed identity in Azure Key Vault's access policies. 3️⃣ Use the syntax @environmentVariables("contoso.ApiKey") Configure the custom connector to use the environment variable. This ensures the API key is dynamically retrieved. 4️⃣ Create a connection Establish a connection to the custom connector using the referenced environment variable.

It should be 3,4,1,6.
