Question 1

A global logistics firm, Northern Trail Shippers, is integrating a legacy on-premise ERP system with Salesforce. The ERP system exposes a SOAP API that strictly requires a specific 'X-Transaction-ID' header for correlation and uses a custom XML envelope structure that deviates slightly from standard SOAP 1.1 specifications. The integration must be synchronous to display immediate results to users in Salesforce. Which approach best addresses the system landscape constraints while meeting the business requirement?

Accepted Answer

Use Apex `HttpRequest` to construct the raw XML envelope manually, set the required headers, and send the request to the ERP endpoint.

Answer

Generate the WSDL from the ERP, import it into Salesforce using 'Generate from WSDL', and use the auto-generated Apex classes to make the callout.

Answer

Implement Salesforce Connect with a custom OData 4.0 adapter to map the ERP XML to External Objects.

Answer

Use Outbound Messaging to send the SOAP request and configure a callback listener in Salesforce to handle the response.

Question 2

An architect is reviewing an existing integration where Salesforce triggers an update to an external Inventory System whenever an Opportunity closes. The Inventory System is currently experiencing intermittent downtime. When the system is down, the synchronous Apex triggers in Salesforce fail, preventing users from closing deals. What is the primary pain point in this system landscape and the optimal architectural pattern to resolve it?

Accepted Answer

Pain Point: Tightly coupled systems; Solution: Implement a Fire and Forget pattern using Platform Events to decouple the transaction.

Answer

Pain Point: Low timeout thresholds; Solution: Increase the Apex callout timeout to 120 seconds in the trigger.

Answer

Pain Point: Lack of Middleware; Solution: Introduce an ETL tool to batch process closed Opportunities nightly.

Answer

Pain Point: Governor Limits; Solution: Move the logic to a @future method to ensure the callout happens eventually.

Question 3

A financial services client requires a Salesforce integration with a core banking system. The security team mandates that no static credentials (username/password) be stored in Salesforce. The banking API supports the OAuth 2.0 Client Credentials flow and requires a client assertion signed with a private key. Which Salesforce feature should be evaluated to meet this authentication need?

Accepted Answer

Named Credentials with a JWT/Client Credentials Auth Provider and a certificate stored in Certificate and Key Management.

Answer

Custom Metadata Types to store the Client ID and Secret, using Apex to generate the JWT.

Answer

Shield Platform Encryption to encrypt the password field in a custom object.

Answer

Connected App with the 'API Only' scope and IP Relaxation.

Question 4

TechCorp is planning an integration that involves transferring sensitive customer Personal Identifiable Information (PII) to an external marketing cloud. The Chief Information Security Officer (CISO) requires that all PII data be classified and that any integration logs stored within Salesforce (e.g., for retry logic) must not expose this PII in clear text. Which solution best addresses the data classification and security requirements?

Accepted Answer

Implement Shield Platform Encryption for the PII fields and ensure the custom integration log object is also encrypted.

Answer

Use Field-Level Security to hide PII fields from the Integration User profile.

Answer

Use an MD5 hash function in Apex to hash PII data before writing it to the logs.

Answer

Classify the data as 'Public' in the Data Classification metadata to bypass security checks.

Question 5
