   A cloud flow calls an external API that has a rate limit of 100 requests per minute. The flow processes a batch of 200 records and calls the API for each record. You need to ensure that the flow does not exceed the rate limit. What should you do?

   • AUse a 'Apply to each' loop with a 'Delay' action inside the loop to wait 1 second between each API call.
   • BUse a 'Do until' loop with a delay between each iteration to control the request rate.
   • CConfigure the HTTP action's retry policy to 'Exponential' with a count of 3 and an interval of 1 second.
   • DIncrease the HTTP action's timeout to 5 minutes to allow more time for the API to respond.

   A Power Automate cloud flow needs to access a third-party API that requires OAuth 2.0 client credentials flow. The client ID and client secret are stored in Azure Key Vault. The flow must authenticate using a service principal in Microsoft Entra ID. You need to configure the flow to securely retrieve the credentials and authenticate to the API. What should you do?

   • AUse the 'Get secret' action from the Azure Key Vault connector to retrieve the client ID and secret, then use the 'HTTP' action to request a token from the API's token endpoint, and then call the API with the token.
   • BUse the 'HTTP with Azure AD' action and select the service principal as the authentication type, passing the client ID and secret as parameters.
   • CStore the client ID and secret in a flow variable and use them in the HTTP action's authentication header.
   • DUse the 'Invoke an HTTP request' action from the Azure Key Vault connector to call the API directly.

   A Power Automate cloud flow calls an external API that occasionally returns HTTP 429 (Too Many Requests) or 500 (Internal Server Error) responses. You need to configure the flow to automatically retry these transient failures without manual intervention. What should you do?

   • AUse a 'Do until' loop with a condition that checks the HTTP status code and repeats the call until a success code is received.
   • BConfigure the HTTP action's retry policy with a fixed interval and a count of 3, and set the action to 'Run after' failure.
   • CSet the HTTP action's 'Retry count' to 0 and rely on the flow's global retry policy.
   • DAdd a 'Scope' action with a 'Run after' configuration that repeats the HTTP call if it fails.
