Three of the 175 questions in this pack

Question 1

A company is designing a Lightning Web Component (LWC) to display transactions aggregated from different sources. Their current system landscape is as follows:

1. Transactions are created at any time through their various on-premise and cloud-based systems.

2. All necessary transactions are replicated to a custom Transaction object in Salesforce. It is updated periodically so it only has a subset of the necessary transactions between updates.

3. Middleware supports publish-subscribe interactions and provides RESTful Enterprise APIs that can retrieve transactions from on-premise and cloud-based systems.

The company wants to address a usability concern regarding incomplete data displayed on the LWC component.

What should the integration architect specify so the LWC will be able to display all the required transactions?

  1. Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.
  2. Call the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.
  3. Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.
  4. Let the Lightning Data Service with an @wire adapter display new values when the custom object records change.
Show answer and explanation

Correct answer: C. Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.

The custom Transaction object only ever holds a subset of the data between replication runs, so the component must fetch the complete set from the systems of record at view time. The middleware already exposes RESTful Enterprise APIs for this. An Apex Continuation makes that long-running callout asynchronously from the Lightning component's controller and processes the response in a callback method, so the user sees every required transaction without the request tying up a synchronous Apex thread while the middleware gathers data from on-premise and cloud systems.

Why the other options are wrong

  • A. Asking middleware to refresh the custom object is still an asynchronous replication, so the component can display data before the update arrives.
  • B. Calling the APIs straight from client-side JavaScript runs into browser security restrictions and bypasses server-side credential management.
  • D. Lightning Data Service only reflects the incomplete custom object, so it cannot show transactions that have not been replicated yet.

Question 2

A global financial company sells financial products and services that include the following:

1. Bank accounts

2. Loans

3. Insurance

The company has a state-of-the-art core banking system that is the master system to store financial transactions, financial products and customer information. The core banking system currently processes 10 million financial transactions per day. The CTO for the company is considering building a community portal so that customers can review their bank account details, update their Information and review their account financial transactions.

What should an integration architect recommend as a solution to enable customer community users to view their financial transactions?

  1. Use Salesforce External Service to display financial transactions in a community Lightning page.
  2. Use Salesforce Connect to display the financial transactions as an external object.
  3. Migrate the financial transaction records to Salesforce custom object and use ETL tool to keep systems in sync.
  4. Use Iframe to display core banking financial transactions data in the customer community.
Show answer and explanation

Correct answer: A. Use Salesforce External Service to display financial transactions in a community Lightning page.

The core banking system stays the system of record and processes 10 million transactions a day, so the transactions should be shown from the source rather than copied into Salesforce. External Services registers the core banking API from its OpenAPI specification and exposes its operations as invocable actions, which a flow on a community Lightning page can call to retrieve a customer's transactions on demand and display them. Customers see current data from the master system without it being stored or synchronized in Salesforce.

Why the other options are wrong

  • B. External objects need an OData or custom adapter in front of the core banking system, while External Services calls its existing API directly from the community page.
  • C. Replicating 10 million transactions a day into a custom object duplicates the master data and consumes heavy storage.
  • D. An iframe embeds another application's UI without integrating the data into the Salesforce security and sharing model.

Question 3

Universal Containers (UC) is a large printing company that sells advertisement banners. The company works with third-party agents on banner initial design concepts. The design files are stored in an on-premise file store that can be accessed by UC internal users and third party agencies.

UC would like to collaborate with the third-party agencies on the design files and allow them to view the design files in the community.

The conceptual design files size is 2.5 GB.

Which solution should an integration architect recommend?

  1. Use Salesforce Files to link the files to Salesforce records and display the record and the files in the community.
  2. Define an External Data Source and use Salesforce Connect to upload the files to an external object. Link the external object using Indirect lookup.
  3. Create a custom object to store the file location URL: when a community user clicks on the file URL, redirect the user to the on-premise system file location.
  4. Create a Lightning component with a Request and Reply integration pattern to allow the community users to download the design files.
Show answer and explanation

Correct answer: C. Create a custom object to store the file location URL: when a community user clicks on the file URL, redirect the user to the on-premise system file location.

The design files come to 2.5 GB, and the files already live in an on-premise store that both internal users and third-party agencies can reach. Storing the file location URL in a custom object lets community users find the right design in context and then be redirected to the on-premise location to open it. This avoids moving very large files into Salesforce while still giving agencies a single place in the community to collaborate on the designs.

Why the other options are wrong

  • A. Uploading 2.5 GB design files to Salesforce Files moves very large files into Salesforce storage instead of linking to where they already live.
  • B. Salesforce Connect exposes external records as external objects; it does not upload or store binary files.
  • D. Streaming multi-gigabyte files through a Request and Reply callout runs into callout size and timeout limits.

What makes the Platform Integration Architect hard

Half the exam is design: translating needs into requirements (22%) and designing the integration (28%). Questions describe a landscape and ask which pattern fits: request and reply or fire and forget, batch data synchronization, remote call-in, UI update from data changes. Then they ask which API carries it: REST, SOAP, Bulk, Streaming, Pub/Sub or Platform Events.

Building the solution is another 23%, covering error handling, retries, idempotency and security. Evaluating the current landscape and business needs add 19%, and maintenance 8%. It is 60 scored questions in 105 minutes with a 67% pass mark. Most wrong answers are a valid API used at the wrong volume or the wrong timing.
