Integration-Architect Exam Results

The best use case for leveraging the existing SAML integration to connect Salesforce with other internal systems is to make Apex SOAP outbound integrations to external web services more secure. SAML can be used to authenticate the Salesforce org as the service provider and obtain a session ID from the external system as the identity provider. This session ID can then be used to make SOAP calls to the external web service without exposing any credentials in the Apex code. Option A is not correct because formula fields with HYPERLINK() do not support SAML authentication. Option C is not correct because Apex REST outbound integrations require OAuth or basic authentication, not SAML. Option D is not correct because API inbound integrations from an external Java client require OAuth or basic authentication, not SAML. References:

The typical and worst-case historical response times, and how many concurrent service calls are being placed are two considerations that an integration architect should make when building a scalable integration solution for synchronous callouts to “available to promise” services. These two factors can affect the performance, reliability, and availability of the integration solution, as well as the user experience of the customer checkout process. The integration architect should design the solution to handle high volumes of service calls, optimize the response times, handle errors and timeouts, and avoid hitting governor limits or service quotas.

The end-to-end response time from the user’s perspective is the time elapsed between the user’s request and the user’s receipt of the final response. In the diagram, this corresponds to the sum of A and H, which are the durations of the synchronous calls from the user interface to the cloud-based application and back. The other durations (B to G) are either internal to the cloud-based application or asynchronous calls that do not affect the user’s perception of response time. Therefore, the correct answer is D, because it represents the sum of A and H.
