Salesforce Integration-Architect Exam With Confidence Using Practice Dumps

Option A is correct because using ESB (Mule) with cache/state management can help to handle the long-running requests from Salesforce and return a request ID or a response if available from the external systems. This way, Salesforce does not have to wait for the externalsystems to respond and can avoid the API gateway timeout1

Option C is correct because using Continuation callouts can make the eligibility check request from Salesforce from Lightning UI at page load without blocking the UI thread. Continuation callouts are asynchronous and can handle long-running requestsup to 60 seconds23

Option E is correct because implementing a ‘Check Update’ button that passes a requestID received from ESB can allow the user to manually check the status of the eligibility check request. This can be useful when theresponse is not available within the Continuation timeout limit or when the user wants to refresh the data4

Option B is incorrect because recommending synchronous Apex callouts from Lightning UI to External Systems via Mule and implementing polling on APIgateway timeout can cause performance issues and user frustration. Synchronous Apex callouts block the UI thread and can only handle requests up to 120 seconds. Polling on API gateway timeout can increasethe network traffic and consume the callout limits25

Option D is incorrect because creating a Platform Event in Salesforce via Remote-Call-In and using the empAPI in the lightning UI to serve 3,000 concurrent users can introduce complexity and scalability issues. Platform Events are meant for event-driven architecture and not for request-response scenarios. Remote-Call-In requires an additional license and configuration. empAPI has a limit of 1,000 concurrent subscribers per channel678

Answer A is valid because creating an Auth provider in the package and setting the consumer key and consumer secretof the connected app in the central org can allow the package to authenticate with the central org using OAuth 2.0. An Auth provider is a configuration that specifies how to connect to an external service that uses a specific identity protocol. A connectedapp is an application that can access Salesforce resources using APIs and standard protocols. The consumer key and consumer secret are credentials that identify the connected app to Salesforce.

Answer C is valid because creating a connected app in the central org and adding the callback URL of each org the package is installed in to redirect to after successful authentication can enable the package to obtain an access token from the central org using OAuth 2.0. The callback URL is a parameter that specifies where the user should be redirected after granting or denying permission to access Salesforce resources. The access token is a credential that can be used to invoke the custom Apex REST endpoint in the central org.

Answer E is valid because using the Auth Provider configured and selecting the identity type as Named Principal with OAuth 2.0 as the protocol and selecting Start Authentication Flow on Save can initiate the authentication flow when installing the package. The identity type determines how the package accesses Salesforce resources on behalf of users or an application. The Named Principal identity type means that the package uses a single credential, such as a username and password or an access token, to access Salesforce resources for all users.TheStart Authentication Flow on Save option means that the package will prompt the user to enter the credential when saving the Auth Provider configuration.

Answer B is not valid because contacting Salesforce support and creating a case to temporarily enable API access for managed packages is not a necessary or recommended action. API access for managed packages is enabled by default and does not require any special permission or configuration from Salesforce support. Moreover, this action does not addressthe security requirement of using a specific integration account in the central org that will be authorized after installation of the package.

Answer D is not valid because using an encrypted field to store the password that the security team enters and using password management for external orgs and setting the encryption method to TLS 1.2 is not a secure or reliable solution. An encrypted field is a custom field that encrypts sensitive data at rest and masks it on the user interface. However, this fielddoes not prevent unauthorized access or leakage of data, as it can be decrypted by users who have the View Encrypted Data permission or by Apex code that runs in system mode. Moreover, this field does not support encryption methods such as TLS 1.2, which are used for securing data in transit, not at rest.

Handle verification process error in the Verification Webservice API in case there is a connection issue to the Webservice or if it responds with an error. This solution ensures that the agent can see an error message when the credit verification process failed, and take appropriate actions. The Verification Webservice API can implementerror handling logic to catch anyexceptions or errors that occur during the callout to the external agencies, and return a meaningful error message to the agent. The agent can then retry the verification process, or escalate the issue to a supervisor. References: Certification - Integration Architect - Trailhead, [Apex Web Services and Callouts]
