Suggested Answer:
Correct Answer Image

Box 1: OAuth 2.0 –
Use API keys if you expect developers to build internal applications that don’t need to access more than a single user’s data. Use OAuth access tokens if you want users to easily provide authorization to applications without needing to share private data or dig through developer documentation.
Requirements. Driving record verification
ג€¢ Driving record verification must only be performed once for each candidate.
ג€¢ Information required for driving record verification must be sent to the driving record verification service automatically after the candidate’s address is verified.
ג€¢ The API must return a value of either Approved or Rejected to indicate whether the candidate has met the company’s requirements.
Box 2: Pass Credentials as parameters
User makes an API call with the authorization header and the token gets validated by using validate-jwt policy in APIM by Azure AD.
Note, see step 4 below.
In this Diagram we can see the OAUTH flow with API Management in which:
Reference Image
1. The Developer Portal requests a token from Azure AD using app registration client id and client secret.
2. In the second step, the user is challenged to prove their identity by supplying User Credentials.
3. After successful validation, Azure AD issues the access/refresh token.
4. User makes an API call with the authorization header and the token gets validated by using validate-jwt policy in APIM by Azure AD.
5. Based on the validation result, the user will receive the response in the developer portal.

Suggested Answer:
Correct Answer Image

Box 1: Modify code at line CS102 to select only required columns
Reduce the number of columns that are retrieved.
Scenario: Error Message: il-specify-column
Symptoms –
Retrieving all columns can cause:
✑ Performance issues due to the amount of data being retrieved
✑ Unintended plug-in/process execution
Guidance –
For optimal performance, you should only select the minimum amount of data needed by your application when querying Microsoft Dataverse data.
ColumnSet Parameter –
When you use the IOrganizationService.Retrieve method set the columnSet parameter to a ColumnSet instance with specified columns. When you use
QueryExpression set the ColumnSet property with the required attributes.
Box 2: Add the following code at line CS203: request.KeepAlive =false;
Scenario: Error message: Il-turn-off-keepalive
Symptoms –
If a plug-in makes external web requests and is trying to use KeepAlive on a closed connection, the plug-in will ultimately fail to execute the web request. If the plug-in is registered:
Synchronously, users may experience:
✑ Unresponsive model-driven apps
✑ Slow client interactions
✑ The browser stops responding
Asynchronously, plug-in executions may take an extended period of time before failing.
Guidance –
In HTTP 1.1, all connections are considered persistent (KeepAlive is true) unless declared otherwise. Due to the fact that plug-ins run in isolation, the Sandbox service translates into them being short-lived executions that generally would not benefit from KeepAlive. To avoid problems with connecting to external services we recommend disabling KeepAlive within plug-ins. This is done by setting KeepAlive to false.
