1. Question 131 · 279 in bank

   The Salesforce instance at Universal Containers currently integrates with a third-party company to validate mailing addresses via REST services. The third-party address verification system recently changed endpoint URLs for all their services from https://th-address-service.3pc.com to https://plc1-mailservice.3pc.com. Everything else remained the same. The developer updated code to reflect this endpoint change, but the mailing address validation service stopped working after the change. What else should be done to complete this web service endpoint change?

   • ACreate a new Remote Site for the new endpoint URL.
   • BUse a Custom Setting with the new endpoint instead of hard coding the URL.
   • CTest the callout properly using HttpCalloutMock.
   • DAdd web service IP addresses to Trusted IP Ranges in the Network Access security controls settings.

   Show answer

   Answer: A

   Explanation

   The address should be registered in Remote Sites so that the instance is accessible to the site address. D doesn't make any sense because D is for inbound connection. (Internet -> SF instance)

2. Question 132 · 279 in bank

   A corporation has many different Salesforce orgs, with some different objects and some common objects, and wants to build a single Java application that can create, retrieve, and update common object records in all of the different orgs. Which method of integration should the application use?

   • ASOAP API with the Partner WSDL
   • BSOAP API with the Enterprise WSDL
   • CApex REST Web Service
   • DMetadata API

   Show answer

   Answer: A

   Explanation

   The Partner WSDL is optimized for use in environments where there are multiple Salesforce orgs with varying configurations. It is loosely typed, which means it can work with data from multiple orgs, regardless of their custom objects and fields. This makes it a suitable choice for an application that needs to interact with common object records across different Salesforce orgs. The Partner WSDL provides a single SOAP API endpoint that lets you create, retrieve, update, and delete records, among other operations.
