   A customer is evaluating the Platform Events solution and would like help in comparing/contrasting it with Outbound Messaging for real-time/near-real time needs. They expect 3,000 customers to view messages in Salesforce. Which three considerations should be evaluated and highlighted when deciding between the solutions? (Choose three.)

   • ANumber of concurrent subscribers to Platform Events is capped at 2,000. An Outbound Messaging configuration can pass only 100 notifications in a single message to a SOAP end point.
   • BBoth Platform Events and Outbound Messaging offer declarative means for asynchronous near-real time needs. They aren't best suited for real-time integrations.
   • CIn both Platform Events and Outbound Messaging, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery.
   • DMessage sequence is possible in Outbound Messaging, but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce.
   • EBoth Platform Events and Outbound Messaging are highly scalable. However, unlike Outbound Messaging, only Platform Events have Event Delivery and Event Publishing limits to be considered.

   Answer: ADE

   Explanation

   I would consider A, B, & E to be the correct answers. C is not correct; outbound messages are queued and retried multiple times D is not correct; platform event recovery is not handled by Salesforce; it's up to the remote system to use replay IDs to retrieve messages are within the recovery window (24 hours or 72 hours, depending on event type).

3. Question 33 · 79 in bank

   A customer of Salesforce has used Platform Events to integrate their Salesforce instance with an external third-party artificial intelligence (AI) system. The AI system provides a prediction score for each lead that is received by Salesforce. Once the prediction score is received, the lead information is saved to Platform Events for other processes. The trigger on the Platform Events has failed ever since it was rolled out to production. What type of monitoring should the integration consultant have considered to monitor this integration?

   • ASet up debug logs for Platform Event triggers to monitor performance.
   • BMonitor Platform Events created per hour limits across the Salesforce instance.
   • CValidate the Platform Event definition matches leads definition.
   • DMonitor the volume of leads that are created in Salesforce.

   Show answer

   Answer: B

   Explanation

   Each Salesforce instance has limits on the number of platform events that can be published or delivered per hour, depending on the edition and license type. If these limits are exceeded, triggers on the platform events may fail or be delayed, which directly affects the integration with the external AI system.

   An architect is asked to build a solution that allows a service to access Salesforce through the API. What is the first thing the architect should do?

5. Question 35 · 79 in bank

   An organization needs to integrate Salesforce with an external system and is considering authentication options. The organization has already implemented SAML using a third-party identity provider (IdP) for integrations between other systems. Which use case can leverage the existing SAML integration to connect Salesforce with other internal systems?

   • AMake Apex REST outbound integrations to external web services more secure.
   • BMake an API inbound integration from an external Java client more secure.
   • CMake formula fields with HYPERLINK() to external web servers more secure.
   • DMake Apex SOAP outbound integrations to external web services more secure.

   Show answer

   Answer: B

   Explanation

   SAML enables you to access multiple web applications using one set of login credentials. As per question an external service is gonna be authenticated in Salesforce. Therefore the only correct option should be B as the others are outbound integrations. HYPERLINK() doesn't have anything related to authentication or access control.

6. Question 36 · 79 in bank

   A company that is a leading provider of courses and training delivers courses using third-party trainers. The trainer for the company has to be verified by 10 different training accreditation verification agencies before providing training for the company. Each training accreditation agency has its own response time, which means it could take days to confirm a trainer. The company decided to automate the trainer accreditation verification process by integrating it with the agency's web services. What is the recommended approach to automate this process?

   • AMake an Apex callout using @future annotation to make the callout to all different agencies. The response should update the trainer status to “verified”.
   • BUse middleware to handle the call out to the 10 different verification services, the middleware will handle the business logic of consolidating the verification result from the 10 services, then make a call-in to Salesforce and update the verification status to “verified”.
   • CCreate a trigger on the trainer record to make a callout to each verification agency’s, write business logic to consolidate the verification then update the trainer status to “verified”.
   • DUse Salesforce External Service to make the call out; Salesforce External Service should check the verification agencies until the result is verified, then update the trainer status to “verified”.

   Show answer

   Answer: B

   Explanation

   Agree on answer A. Future annotation won't do the job for this use case because Future Apex Methods have a maximum execution time of 60 seconds.

8. Question 38 · 79 in bank

   A company needs to be able to send data from Salesforce to a home grown system behind a corporate firewall. The data needs to be pushed only one way and doesn't need to be sent in real time. The average volume is 2 million records per day. What should an integration architect consider when choosing the right option in building the integration between the external system and Salesforce?

   • ADue to high volume of records, number of concurrent requests can hit the limit for the REST API call to the external system.
   • BDue to high volume of records, the external system will need to use a BULK API Rest endpoint to connect to Salesforce.
   • CDue to high volume of records, Salesforce will need to make a REST API call to the external system.
   • DDue to high volume of records, a third party integration tool is required to stage records off platform.

   Show answer

   Answer: B

   Explanation

   BULK API data is PUSHED from salesforce to external, via a pull request from the external system (which works easily through the firewalls etc). I think the pull/push terminology is just a little confusing.

   Universal Containers (UC) owns a variety of cloud-based applications, including Salesforce, alongside several on-premise applications. The on-premise applications are protected behind a corporate network with limited outside access to external systems. UC would like to expose data from the on-premise applications to Salesforce for a more unified user experience. The data should be accessible from Salesforce in real time. Which two actions should be recommended to fulfill this system requirement? (Choose two.)

   • ARun a batch job with an extract, transform, load (ETL) tool from an on-premise server to move data to Salesforce.
   • BDevelop an application in Heroku that connects to the on-premise database via an Open Database Connectivity (ODBC) string and Virtual Private Cloud (VPC) connection.
   • CDevelop custom APIs on the company's network that are invokable by Salesforce.
   • DDeploy MuleSoft to the on-premise network and design external facing APIs to expose the data.

   Show answer

   Answer: CD

   Explanation

   B is incorrect because we are connecting to multiple applications. B assumes we are connecting to a database. C is obviously doable. My company did it recently with a named credential that had information to authorize against the APIs. People create APIs and expose them to Salesforce by use of a credential, all the time.
