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:
* 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.
* 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.
* 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.Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.
• B.Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
• C.Write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
• D.Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.

There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user.
The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, *Maximum view state size limit exceeded.
What step should the developer take to resolve this issue?

• A.Split the layout to filter records in one Visualforce page and display the list of records in a second page using the same Apex Controller.
• B.Adjust any code that filters by picklist values since they are not indexed.
• C.Use a StandardSetController or SOQL LIMIT in the Apex controller to limit the number of records displayed at a time.
• D.Remove instances of the transient keyword from the Apex controller to avoid the view state error.
