Integration-Architect Exam Dumps - Salesforce Integration Architecture Designer Questions and Answers

Platform Events are a type of event-driven architecture that allows you to publish and subscribe to events in Salesforce and external systems. To subscribe to an event, the integration user in Salesforce needs read access to the event entity, which defines the schema and properties of the event message. To publish an event, the integration user in Salesforce needs create permission on the event entity, which is a special type of sObject that can be inserted into the platform event queue. Error handling must be performed by the remote service because the event is effectively handed off to the remote system for further processing. Salesforce does not guarantee the delivery or acknowledgment of the event by the external system. The external system should implement its own logic to handle errors, such as retrying failed events, logging errors, or sending notifications.

Creating Salesforce Cases using the Salesforce REST, SOAP or Bulk API is a solution that can allow the logging service to create case records in Salesforce based on the exceptions received from the middleware platform. This way, the logging service can use the standard APIs to interact with Salesforce and leverage the features and functionality of the case object. Creating Salesforce Cases conditionally using automatic Case creation rules is a solution that can allow the logging service to create case records in Salesforce based on predefined criteria and actions. This way, the logging service can reduce the number of API calls and avoid creating unnecessary or duplicate cases. Receiving Application Events through Change Data Capture (CDC) is not a solution that is related to this requirement, as CDC is used for capturing data changes in Salesforce and sending them to external systems, not for receiving data from external systems. Subscribing to the Application Exceptions using the Salesforce Streaming API is also not a solution that is related to this requirement, as Streaming API is used for subscribing to events or notifications from Salesforce, not for sending data to Salesforce.

An API gateway is a component that acts as a single point of entry for all cloud applications to access on-premise resources and services. It can provide security, routing, transformation, and other features to facilitate integration. An API gateway component should be deployable behind a DMZ or perimeter network, which is a subnetwork that separates the internal network from the external network and provides an additional layer of security. The middleware solution should also be capable of establishing a secure API gateway between cloud applications and on-premise resources, which may involve using protocols such as HTTPS, SSL/TLS, or VPN. The OAuth security protocol is not a requirement for choosing a middleware solution, as it is a standard for authorizing access to resources on behalf of a user. The middleware solution’s ability to interface directly with databases via an ODBC connection string is also not a requirement, as it is a specific feature that may or may not be needed depending on the integration scenario.

• Answer A is valid because creating an Auth provider in the package and setting the consumer key and consumer secret of 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 connected app 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. The Start 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 address the 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 field does 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.

The Connect REST API is designed to access Chatter feeds and social data such as users, groups, followers, and files. By using this API, the integration can query the Chatter posts that include the #thanksNTO hashtag and post them to Twitter using another API. The REST API, Streaming API, and Apex REST are not specific to Chatter and do not provide the same level of functionality and ease of use as the Connect REST API2

The recommendations that the Salesforce integration architect should make to fulfill the requirements around caching, queuing, error handling, alerts, retries, event handling, etc. are based on the best practices and capabilities of the middleware tools. The recommendation B is valid because middleware tools can provide true message queueing for integration scenarios that require asynchronous processing, guaranteed delivery, load balancing, etc. The recommendation D is valid because middleware tools can handle various events that may occur during the integration process, such as logging errors, sending notifications, triggering recovery actions, etc. The recommendation E is valid because middleware tools can support the publish/subscribe pattern for event-driven integration, where the middleware can route messages from publishers to subscribers based on topics or filters. The recommendation A is not valid because transforming a fire-and-forget mechanism to request-reply does not improve performance, but rather increases the latency and complexity of the integration. The recommendation C is not valid because message transformation and protocol translation are tasks that are better suited for middleware tools than Salesforce, as they can handle different formats and protocols more efficiently and flexibly23

Using a Connected App for each external system integration is a good solution because it can provide security, auditing, and monitoring features for each integration. A Connected App is an application that can connect to Salesforce using APIs and OAuth as an authentication protocol. A Connected App can also enforce policies such as IP restrictions, login hours, and session timeout for each integration. Using a shared integration user for the three external system integrations is not a good solution because it violates the principle of least privilege, as well as makes it difficult to audit the activities of each system. Using a shared Connected App for the three external system integrations is also not a good solution because it does not allow for granular control and visibility of each integration. Using a unique integration user for each external system integration is not enough to meet the security and auditing requirements, as it does not provide any mechanism for authentication, authorization, or encryption.

Middleware should coordinate request delivery and payment processing, and Payment System should process a payment request only once. This solution ensures that each payment request is delivered to the Payment System in a reliable and consistent manner, and avoids duplicate or conflicting updates to the same Payment Request record. Middleware can act as a mediator between the Data Entry Point and the Payment System, and implement logic to handle errors, retries, and acknowledgments. Payment System can use the globally unique identifier to check if a payment request has already been processed, and avoid processing it again.

The mobile device should make a REST Apex inbound call to meet the requirement. A REST Apex inbound call allows the mobile device to invoke custom Apex logic on Salesforce using a RESTful interface. The Apex logic can then access the geolocation field using the user’s OAuth token and update it with the GPS coordinates from the mobile device. The geolocation field is secured with Field Level Security, so the user can view the value without changing it. A SOAP API inbound call or a REST API inbound call would not be able to access the custom geolocation field, as they are not supported by the standard Salesforce objects and fields.

Streaming API is the best option for sending real-time notifications of changes to Salesforce data. Streaming API uses a publish-subscribe model to push relevant data to subscribers without polling. Streaming API supports PushTopic events, which are based on SOQL queries that define the data changes to listen for. The affiliate company can subscribe to a PushTopic event on the NTO Salesforce org and receive notifications whenever the data that matches the query changes. This way, the affiliate company can be informed of any updates to the opportunities in the NTO Salesforce instance.
