The authentication is achieved by handling it in the code. A Named Credential is a type of metadata that specifies the URL of a calloutendpoint and its required authentication parameters. An Apex callout is a way to invoke anexternal web service or API from Apex code. When using a Named Credential with an Apex callout, the authentication is handled by the Apex code that invokes the callout. The Apex code can use the HttpRequest class to set the endpoint, method, headers, and body of the callout request, and use the Http class to send the request and receive the response. The Apex code can also use the NamedCredential class to access the properties of the Named Credential, such as the principal type, protocol, and credential type. Handling authentication with login flows is not a valid option because login flows are a way to customize the user login process in Salesforce, not for external web services or APIs. Connecting via Salesforce Connect or Communities is not a valid option because they are not related to Apex callouts or Named Credentials.

 The OAuth protocol is a standard way to authorizeaccess to web resources. By configuring a connected app with an authorization endpoint of the API gateway, Salesforce can obtain an access token from the API gateway and use it to invoke the external API securely. This avoids the need to manage certificates oruser credentials for authentication2

Option C is correct because including selective criteria in query filters can improve the performance of the integration. Selective criteria are filters that reduce the number of records that need to be scanned by the query optimizer, such as indexed fields, standard indexes, or custom indexes. Selective criteria can help the query run faster and avoid hitting the query timeout limit or the query row limit.

Option D is correct because removing the sharing restrictions can improve the performance of the integration. Sharing restrictions are filters that limit the access to records based on the user’s role, profile, or sharing rules.Sharing restrictions can add complexity and overhead to the query execution, as they require additional joins and calculations. Removing the sharing restrictions can simplify the query and reduce the number of records that need to be processed.

Option A is incorrect because including non-selective criteria in query filters can degrade the performance of the integration. Non-selective criteria are filters that do not reduce the number of records that need to be scanned by the query optimizer, such as non-indexed fields, formula fields, or OR conditions. Non-selective criteria can cause the query to run slower and hit the query timeout limit or the query row limit.

Option B is incorrect because removing the query filters can degrade the performance of the integration. Query filters are conditions that specify which records to retrieve from the database, such as WHERE clauses or LIMIT clauses. Query filters can help the query run faster and avoid retrieving unnecessary or unwanted data. Removing the query filters can increase the number of records that need to be processed and transmitted by the integration.
