Salesforce Salesforce Certifications PDII Questions & Answers

• Question 381:

  Recently a Salesforce org's integration failed because it exceeded the number of allowed API calls in a 24-hour period. The integration handles a near real-time, complex insertion of data into Salesforce. The flow of data is as follows:

  1.

  The integration looks up Contact records with a given email address and, if found, the integration adds a Task to the first matching Contact it finds.

  2.

  If a match is not found, the integration looks up Lead records with a given email address and, if found, the integration adds a Task to the first matching Lead it finds.

  3.

  If a match is not found, the integration will create a Lead and a Task for that newly created Lead.

  What is one way in which the integration can stay near real-time, but not exceed the number of allowed API calls in a 24-hour period?

  A. Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.

  B. write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.

  C. Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.

  D. Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.

  Correct Answer: C

• Question 383:

  What is a benefit of JavaScript remoting over Visualforce Remote Objects?

  A. Supports complex server-side application logic

  B. Does not require any JavaScript code

  C. Does not require any Apex code

  D. Allows for specified re-render targets

  Correct Answer: A

  Either remote object or @remoteAction requires a JS callback,promise, asyncandawait function to parse the JSON result from back-End to client side. For example, you can easily construct a wrapper class using @remoteAction in Apex where information from multiple queries or proxy variables can be brought together. For remote object you will need JS to do "promise.all" in order to cover that kind of wrapper in Apex, which will be very complex and hard to read

  C. Decorate the server-side method with @AuraEnabled(storable=true).
