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.

Using Salesforce custom object, custom REST API and ETL is a better solution than using Salesforce standard object, REST API and ETL. A custom object can store the order information and provide more flexibility and control over the data model, validation rules, triggers, etc. A custom REST API can be used to create orders in real time from Salesforce, using the ESB as a proxy to communicate with the legacy system. An ETL tool can be used to sync the order history and status from the legacy system to Salesforce, using the last modified date as a filter. This way, sales reps can see the order history and the most up-to-date information on current order status, and managers can run reports on order volumes and fulfillment timelines. A standard object, such as Order, may not meet all the business requirements and may require more customization than a custom object. A standard REST API may not provide enough security and error handling for creating orders in real time. Reference: Salesforce Integration Architecture Designer Resource Guide, page 18

Visually monitor in the Salesforce UI using the “Bulk Data Load Jobs” in Salesforce in the setup menu, and use the getBatchInfo method in the Java application to monitor the status of the jobs from the Java application. These two methods can help the Technical Architect to monitor the nightly batch loads into Salesforce from an external system with a custom Java application using the Bulk API. The “Bulk Data Load Jobs” page in Salesforce shows the status, progress, and results of each batch load job. The getBatchInfo method in the Java application returns a BatchInfo object that contains information about a batch, such as its ID, state, number of records processed, and number of errors.

Change Data Capture is a feature that enables you to receive near-real-time changes of Salesforce records, including create, update, delete, and undelete operations. Change Data Capture retains change events in the event bus for up to three days, so you can resume data replication from the point of failure. Change Data Capture also provides a consistent and reliable way to synchronize data changes with external systems, without the need for custom triggers or code. Reference: Salesforce Integration Architecture Designer Resource Guide, page 24

• Answer D is valid because using Bulk API 2.0 for both inserting and querying data can meet the requirements of loading and extracting large volumes of data in a day. Bulk API 2.0 is a RESTful API that allows creating, updating, deleting, or querying millions of records asynchronously by uploading or downloading CSV or JSON files. Bulk API 2.0 has several advantages over Bulk API 1.0, such as:
• Answer A is not valid because using Bulk API 2.0 for inserting data and REST API for querying data is not an optimal solution for handling large volumes of data in a day. REST API is a synchronous API that allows creating, updating, deleting, or querying individual records or small batches of records using HTTP methods. REST API has several limitations and drawbacks for this use case, such as:
• Answer B is not valid because using Bulk API 1.0 for both inserting and querying data is not a feasible solution for handling large volumes of data in a day. Bulk API 1.0 is a SOAP-based API that allows creating, updating, deleting, or querying millions of records asynchronously by uploading or downloading XML or CSV files. Bulk API 1.0 has several limitations and drawbacks compared to Bulk API 2.0, such as:
• Answer C is not valid because using Bulk API 1.0 for inserting data and REST API for querying data is not a suitable or reliable solution for handling large volumes of data in a day. As explained above, both Bulk API 1.0 and REST API have limitations and drawbacks that may affect the performance, efficiency, and scalability of the integration.

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

• Option C is correct because Salesforce should be the system of record for their customers and prospects, as it is the CRM solution that the sales and service associates use to view and log their interactions with them. Salesforce can also integrate with the Marketing and ERP solutions to display relevant information from those systems, such as campaign history, invoices, and orders12
• Option A is incorrect because ERP is not a suitable system of record for customers and prospects, as it is mainly focused on invoicing and order fulfillment. ERP may not have all the data that the sales and service associates need to interact with them, such as contact details, preferences, activities, and opportunities. ERP may also have different data models and definitions than Salesforce and Marketing, which can cause data quality and consistency issues3
• Option B is incorrect because Marketing is not a suitable system of record for customers and prospects, as it is mainly focused on email campaigns. Marketing may not have all the data that the sales and service associates need to interact with them, such as account information, service cases, contracts, and quotes. Marketing may also have different data models and definitions than Salesforce and ERP, which can cause data quality and consistency issues.
• Option D is incorrect because creating a new custom database for customers and prospects is not a feasible or efficient solution, as it would require additional development, maintenance, and integration costs. It would also create another layer of complexity and potential data duplication in the system landscape. Salesforce already provides a robust and flexible platform for managing customer and prospect data, which can be easily customized and integrated with other systems.

• 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.

The Fire and Forget pattern is suitable for this business use case because it allows sending a message from Salesforce to the remote system without waiting for a response or acknowledgement. This reduces the latency and complexity of the integration and enables asynchronous processing of the orders in the remote system. The platform event defined in Salesforce can be used to publish the order details to the remote system, which can subscribe to the event and create the order accordingly1

 Both Platform Events and Outbound Message offer declarative means for asynchronous near-real time needs. They aren’t best suited for real-time integrations (A). In both Platform Events and Outbound Messages, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery (B). Message sequence is possible in Outbound Message but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce ©. Number of concurrent subscribers to Platform Events is capped at 2,000. An Outbound Message configuration can pass only 100 notifications in a single message to a SOAP end point (D). Both Platform Events and Outbound Message are highly scalable. However, unlike Outbound Message, only Platform Events have Event Delivery and Event Publishing limits to be considered (E). Reference: Salesforce Integration Architecture Designer Resource Guide, page 23

A Connected App is a framework that enables an external application to integrate with Salesforce using APIs and standard protocols, such as OAuth. By configuring a Connected App in Salesforce, the integration can authenticate the middleware and grant access to the Salesforce data and services. This is a secure and flexible solution that does not require configuring Remote Site Settings, API Gateway, or Firewall and reverse proxy2

References: 1: BatchApexErrorEvent 2: Connected Apps

The system requirement is to expose data from the on-premise applications to Salesforce for a more unified user experience in real-time. The possible actions that can fulfill this requirement are:

• Answer B is valid because developing custom APIs on the company’s network that are invokable by Salesforce can allow Salesforce to access the data from the on-premise applications in real-time. However, this action requires opening a firewall port or using a reverse proxy to allow Salesforce to communicate with the on-premise APIs securely3
• Answer C is valid because deploying MuleSoft to the on-premise network and designing externally facing APIs to expose the data can also enable Salesforce to access the data from the on-premise applications in real-time. MuleSoft is an integration platform that can connect various systems and applications using APIs and standard protocols. MuleSoft can also handle security, orchestration, transformation, and other integration aspects.
• Answer A is not valid because developing an application in Heroku that connects to the on-premise database via an ODBC string and VPC connection is not a real-time solution. Heroku is a cloud platform that can host web applications and services, but it cannot expose data from an on-premise database directly to Salesforce. To use Heroku for this purpose, an ETL tool or a middleware solution would be needed to synchronize the data between the on-premise database and Heroku, which would introduce latency and complexity to the integration.
• Answer D is not valid because running a batch job with an ETL tool from an on-premise server to move data to Salesforce is also not a real-time solution. ETL stands for extract, transform, and load, which is a process of moving data from one system to another in batches. ETL tools can be used for data migration or integration, but they cannot provide real-time access to data from on-premise applications to Salesforce. ETL tools also have limitations on data volume, frequency, and reliability.

• 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.

Using request and reply is the recommended integration pattern for this use case because it allows the support agents to send a request to the core banking system and receive a response with the bank account ID in real-time. This way, the support agents can inform the customers with the newly created bank account ID without any delay or inconsistency. Using streaming API to generate push topic is not a good solution because it is used for event-driven integration, not for web-service integration. Using outbound message is also not a good solution because it is a Salesforce-specific feature that uses SOAP web services, which may not be compatible with the core banking system. Using Salesforce platform event is also not a good solution because it is used for event-driven integration, not for web-service integration. Reference: Salesforce Integration Architecture Designer Resource Guide, page 29-30

The Partner WSDL is the best option for creating an integration that might be used for more than one Salesforce organization and different metadata. The Partner WSDL is loosely typed and can reflect against any configuration of Salesforce. It is static and does not change if modifications are made to an organization’s Salesforce configuration. Therefore, it is more flexible and adaptable than the Enterprise WSDL, which is strongly typed and bound to a specific configuration of Salesforce1

References: Differences between Salesforce provided WSDL files

 These are three considerations that an Integration Architect should consider when recommending Platform Event as an Integration solution. Platform Events are a type of event-driven architecture that allows you to publish and subscribe to custom events in Salesforce and external systems. Platform Events have some limitations and features that an Integration Architect should be aware of, such as:

• Inability to query event messages using SOQL. Platform Events are not stored in Salesforce database, but in an event bus that retains them for 24 hours. You cannot use SOQL to query event messages, but you can use the EventLogFile object or the Event Monitoring feature to access them.
• Inability to create a Lightning record page for platform events. Platform Events are not standard or custom objects, but a special type of sObject that can be inserted into the event bus. You cannot create a Lightning record page for platform events, but you can use Apex triggers, Lightning web components, or CometD clients to subscribe to them.
• When you delete an event definition, it’s permanently removed and can’t be restored. An event definition is a metadata type that defines the schema and properties of a platform event message. You can create or modify event definitions in Salesforce Setup or using Metadata API. However, if you delete an event definition, it’s permanently removed from your org and can’t be restored. You also lose access to any event messages that use that event definition.

Outbound Messaging and Platform Events are both suitable solutions for capturing and sending business events from Salesforce to an external system in real time. Outbound Messaging allows you to specify workflow rules that send SOAP messages with field values to designated endpoints1. Platform Events are secure and scalable messages that contain data and can be published and subscribed to using various APIs2. A trigger or a custom Apex controller can be used to publish platform events from Salesforce34. A callout is not a suitable solution because it is a synchronous request that may fail or timeout, and it also consumes API limits. A contract-first Outbound Messaging interface is not a valid option because Outbound Messaging uses a predefined WSDL that cannot be customized

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. References: Certification - Integration Architect - Trailhead, [Integration Patterns and Practices]

 Push Topic Events can define a custom payload, which is one of the factors that should be considered when choosing a Streaming API implementation. Push Topic Events are based on SOQL queries that define the data changes to be notified of. You can specify the fields to be returned in the event message by using the SELECT clause in the query. This allows you to customize the payload according to your needs2

References: Create a PushTopic

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:

• Named Credentials as Callout Endpoints
• SAML SSO with Salesforce as the Service Provider

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. References: Certification - Integration Architect - Trailhead, [Callout Limits and Limitations], [Integration Patterns and Practices]

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.

The best solution for this scenario is to use a custom object to store the file location URL and redirect the community user to the on-premise file store when they click on the URL. This way, the community user can access the large design files without having to download them or use any external data source. Option A is not feasible because the Request and Reply integration pattern is not suitable for large files and would cause performance issues. Option B is not correct because Salesforce Connect cannot upload files to an external object, only data. Option D is not possible because Salesforce Files has a limit of 2 GB per file, and the design files are 2.5 GB in size. References:

• Salesforce Connect Developer Guide
• Salesforce Files Developer Guide

 A trigger is a programmatic way of executing some logic when a record is inserted, updated, deleted, or undeleted in Salesforce. A trigger can invoke an Apex class that contains the code to perform a REST callout to an external system. A REST callout is a way of sending an HTTP request to a service endpoint and receiving a response. A REST callout can be synchronous or asynchronous, depending on whether the Apex code waits for the response before continuing the execution. A synchronous callout is suitable for scenarios where the response is needed immediately, such as order fulfillment1.

An Apex proxy class is a class that is generated from a WSDL (Web Service Description Language) document of an external SOAP web service. An Apex proxy class can be used to make a SOAP callout to the external web service, but not a REST callout. A SOAP callout is another way of sending an HTTP request to a service endpoint and receiving a response, but it uses a different format and protocol than REST2.

Process Builder is a declarative tool that allows you to automate business processes by defining criteria and actions. Process Builder can invoke an Apex class that implements the Process.Plugin interface, which allows you to extend the functionality of Process Builder with custom logic. However, Process Builder does not support synchronous callouts, because it runs in the background and does not wait for the response from the external system. Process Builder only supports asynchronous callouts, which are executed after the transaction is committed3.

Batch Apex is a way of processing large volumes of data asynchronously by breaking them into smaller batches of records. Batch Apex can be used to perform complex or long-running operations on data, such as data cleansing, archiving, or integration. Batch Apex can make callouts to external systems by implementing the Database.AllowsCallouts interface in the batch class. However, Batch Apex is not suitable for scenarios where the callout needs to be synchronous, because it runs in the background and does not wait for the response from the external system. Batch Apex also has some limitations, such as the maximum number of batches in the queue, the maximum number of records per batch, and the maximum number of callouts per batch4.

A Lightning Component is a reusable unit of user interface that can be used to build modern web apps with Salesforce. A Lightning Component can make a callout to an external system by using JavaScript code or by invoking an Apex controller class that contains the logic for the callout. A Lightning Component can make a synchronous or asynchronous callout, depending on whether the JavaScript code or Apex code waits for the response before continuing the execution. However, a Lightning Component is not a good choice for scenarios where the callout needs to be triggered by a record change, such as when an opportunity is closed/won. A Lightning Component requires user interaction, such as clicking a button or loading a page, to initiate the callout5.

Therefore, the correct answer is A, because writing a trigger that invokes an Apex class to make a REST callout to the Order Management System is the only option that satisfies the requirements of making a synchronous callout when an opportunity is closed/won.

The correct answer is C, Request-Reply: Enhanced External Services invokes a REST API. This is because Enhanced External Services allows you to register an external web service that has an OpenAPI 2.0 specification and use it as an invocable action in a Lightning flow. This way, you can check the preferences from the external service in real-time and get the response in Boolean and string values. The other options are not suitable for this scenario because:

• A, Fire and Forget: Process-driven platform events publishes events on Salesforce Event Bus, is a pattern that is used for asynchronous integration, where the sender does not expect a response from the receiver. This is not suitable for checking preferences in real-time.
• B, Remote Call-In: Salesforce REST API with REST Composite Resources, is a pattern that is used for integrating external applications with Salesforce by calling the Salesforce REST API. This is not suitable for invoking an external service from a Lightning flow.
• D, Data Virtualization: Salesforce Connect map data external REST data in external objects, is a pattern that is used for accessing external data without copying or synchronizing it to Salesforce. This is not suitable for checking preferences in real-time or using them in a Lightning flow.

User Interface API should be used to implement this integration. User Interface API is a RESTful API that allows you to create native mobile apps and custom web apps with the look and feel of Salesforce’s Lightning Experience. User Interface API provides access to metadata, data, and UI components, such as layouts, actions, picklists, and record types. User Interface API also handles security, performance, and compatibility across different devices and browsers. References: Certification - Integration Architect - Trailhead, [User Interface API Developer Guide]

 Idempotent design means that the same request can be repeated multiple times without changing the outcome. This is useful for avoiding duplicate orders in case of network failures or timeouts. By implementing idempotent design, the sales representatives can retry the order(s) in question without creating duplicates in the manufacturing system. Outbound messaging is not a reliable solution because it does not guarantee delivery or acknowledgement of messages. Scheduled apex is not a real-time solution and may not catch all the duplicate or missing orders

Using middleware queuing and buffering is a solution that can handle errors during service outages by storing the messages in a queue until the service is available again. This way, Salesforce does not lose any data or encounter any failures when the service is down. Using @future jobld and custom scheduled apex process to retry failed service calls is not a good solution because it can consume a lot of governor limits and create a lot of duplicate records. Using Outbound Messaging to automatically retry failed service calls is also not a good solution because it has a limited number of retries and a fixed retry interval, which may not be sufficient for long service outages. Using Platform Event replayld and custom scheduled Apex process to retrieve missed events is not applicable for this scenario because Platform Events are used for event-driven integration, not for web-service integration.
