[All Salesforce Certified Platform Developer II (Plat-Dev-301) Questions]

A developer is working on an integration between Salestorce and an external system. The integration requires sending a large amount of data to the external systern, which can cause long response times and timeouts.

To optimize the performance and avoid timeouts, which technique should be used?

Show Suggested Answer Hide Answer
Suggested Answer: B

Implementing an asynchronous callout using the Continuation class is the optimal solution to handle long response times and avoid timeouts in Salesforce. It allows the Apex code to make a long-running request to an external service and free up the thread to serve other requests.

I think using the Continuation class is better for async calls.

Chained batch Apex is a solid choice for large data.

Chained batch Apex sounds familiar, but I can't recall if it's specifically for callouts or just for processing large data sets.

Increasing the timeout limit seems like a quick fix, but I don't think it really solves the underlying issue of performance.

I think we practiced a similar question where we had to optimize callouts. I feel like the Continuation class might be the right choice here.

I remember we discussed using asynchronous methods to handle long-running processes, but I'm not sure if @future or Continuation is better for this scenario.
