Salesforce Certified Platform Integration Architect Sample Questions (Q11-Q16):

NEW QUESTION # 11
Northern Trail Outfitters needs to make synchronous callouts to "available-to-promise" services to query product availability and reserve inventory during the customer checkout process. What should an integration architect consider when building a scalable integration solution?

A. The maximum query cursors open per user on the service
B. The number of batch jobs that can run concurrently
C. How many concurrent service calls are being placed

Answer: A

NEW QUESTION # 12
Northern Trail Outfitters needs to present shipping costs and estimated delivery times to its customers. Shipping services used vary by region and have similar but distinct service request parameters. Which integration component capability should be used?

A. Apex REST Service to implement routing logic to the various shipping service
B. Enterprise Service Bus to determine which shipping service to use and transform requests to the necessary format
C. Enterprise Service Bus user interface to collect shipper-specific form data

Answer: B

Explanation:
When dealing with multiple external service providers (like different regional shippers) that have varying API requirements, the most scalable architectural choice is an Enterprise Service Bus (ESB) or middleware solution. This scenario describes a classic "Orchestration" and "Transformation" use case.
An ESB excels at:
1. Routing/Mediation: The ESB can receive a single, standardized request from Salesforce ("Get Shipping Rates") and use business logic to determine which regional carrier's API should be called.
2. Transformation: Each carrier likely has a distinct XML or JSON schema. The ESB can transform the common data model sent by Salesforce into the specific format required by the chosen shipper.
3. Protocol Bridging: If one shipper uses SOAP and another uses REST, the ESB handles these technical differences, allowing Salesforce to interact with a single, simplified interface.
Option A (Apex REST) would require the Salesforce team to maintain custom code for every new shipping provider added, leading to high technical debt and maintenance challenges. Option C is incorrect because an ESB is a back-end infrastructure component, not a user interface tool.
By utilizing an ESB, Northern Trail Outfitters decouples Salesforce from the complexities of the shipping providers' APIs. This "Hub and Spoke" model means that adding a new regional shipper in the future only requires configuration within the ESB, rather than a full code deployment in Salesforce. This provides the agility and architectural separation necessary for a global retail operation.

NEW QUESTION # 13
A business requires automating the check and updating of the phone number type classification (mobile vs. landline) for all incoming calls delivered to its phone sales agents. The following conditions exist:
At peak, the call center can receive up to 100,000 calls per day.
The phone number type classification is a service provided by an external service API.
Business is flexible with timing and frequency to check and update the records (throughout the night or every 6-12 hours is sufficient).
A Remote-Call-In pattern and/or Batch Synchronization (Replication via ETL: System -> Salesforce) are determined to work with a middleware hosted on customer premise. In order to implement these patterns and mechanisms, which component should an integration architect recommend?

A. ConnectedApp configured in Salesforce to authenticate the middleware
B. An API Gateway that authenticates requests from Salesforce into the middleware (ETL/ESB)
C. Remote Site Settings configured in Salesforce to authenticate the middleware

Answer: A

Explanation:
In this scenario, the architecture involves a Remote-Call-In pattern or Batch Synchronization, where an external system (the middleware or ETL tool) initiates communication with Salesforce to update records. For any external system to securely access Salesforce APIs and perform these updates, it must be authenticated and authorized.
The Connected App is the foundational framework that allows an external application to integrate with Salesforce using APIs and standard protocols, such as OAuth 2.0 and SAML. By configuring a Connected App, the architect can define which permissions (Scopes) the middleware has, such as the ability to access data via the REST or Bulk API. This is the correct choice because the middleware needs to "log in" to Salesforce to push the phone classification data back into the Account or Contact records.
Option B, an API Gateway, is typically used to manage and secure requests going out of an organization to external services, or to provide a facade for on-premise APIs; it does not handle the inbound authentication into Salesforce itself. Option C, Remote Site Settings, is a configuration used solely to permit Salesforce to make outbound calls to a specific external URL (for example, if Salesforce were calling the phone classification service directly via Apex).
Given that the business is flexible with timing (allowing for nightly or 12-hour syncs) and handles 100,000 calls, a Batch Synchronization pattern via an ETL tool is highly efficient. The ETL tool will authenticate against the Connected App using a secure OAuth flow (such as the JWT Bearer Flow for server-to-server integration), retrieve the new phone numbers, call the external classification API, and then bulk-update the Salesforce records. This setup ensures a secure, scalable, and manageable integration that respects Salesforce's security architecture while meeting the high-volume data requirements of the call center.

NEW QUESTION # 14
An integration architect has received a request to prevent employees that leave the company from accessing data in Salesforce after they are deactivated in the company's HR system. What should the integration architect determine before recommending a solution?

A. Inbound integration requirements, then identify frequency
B. Data access prevention requirements, integration requirements, and system constraints
C. Data access prevention requirements, then identify frequency

Answer: A

NEW QUESTION # 15
Given the diagram above, a Salesforce org, middleware, and Historical Data store exist with connectivity between them. Historical records are archived from Salesforce, moved to a Historical Data store (which houses 20 million records and growing), and fine-tuned to be performant with search queries. When reviewing occasional special cases, call center agents that use Salesforce have requested access to view the historical case items that relate to submitted cases.

Which mechanism and patterns are recommended to maximize declarative configuration?

A. Use an ESB tool with a Fire and Forget pattern, and then publish a platform event for the requested historical data.
B. Use an ESB tool with a Data Virtualization pattern, expose the OData endpoint, and then use Salesforce Connect to consume and display the External object alongside the Case object.12
C. Use an ESB tool with a Request and Reply pattern, and then make a real-time Apex callout to the ESB endpoint to fetch3 and display historical Data in a custom Lightning compo4nent related to the Case object.

Answer: B

Explanation:
When designing a solution to view large volumes of archived data (over 20 million records) without physically storing them back in Salesforce, a Data Virtualization pattern is the architecturally preferred approach. This pattern allows users to view and interact with external data in real-time without the overhead of data replication, which would otherwise consume significant storage and impact platform performance.
To maximize declarative configuration, the Salesforce Platform Integration Architect should recommend Salesforce Connect. Salesforce Connect allows for the creation of External Objects, which behave much like standard objects but point to data residing outside of Salesforce. This is achieved by having the middleware (ESB) expose the Historical Data store via an OData (Open Data Protocol) endpoint. Once configured, call center agents can view historical case items directly on the Case record page using standard related lists or lookups, all configured through the point-and-click interface rather than custom code.
The provided landscape diagram illustrates a clear path from Salesforce through middleware to the Historical Data Store. Option A leverages this by using the ESB to bridge the protocol gap. Because the data store is already "fine-tuned to be performant with search queries," Salesforce Connect can efficiently query only the specific historical records needed for the current case view.
In contrast, Option B requires a "Request and Reply" pattern using Apex callouts and custom Lightning components. While functional, this is a code-heavy approach that increases technical debt and does not meet the "maximize declarative configuration" requirement. Option C, using "Fire and Forget" with Platform Events, is unsuitable for a synchronous "view data" request; Platform Events are asynchronous and would require a complex, custom-built UI to "wait" for and display the response. Therefore, the combination of OData and Salesforce Connect provides the most seamless, scalable, and low-maintenance solution for call center agents.
