C)

D)

A. Option D
B. Option C
C. Option B
D. Option A

질문 # 190
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?

A. Use a chained batch Apex to split the data into smaller batches.
B. Use the @future annotation to make the callout asynchronous.
C. Implement an asynchronous callout using the Continuation class,
D. Increase the timeout limit in the callout options,

정답：C

설명：
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.

Which two statements are true regarding these issues and resolution?
Choose 2 answers

A. The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts in production.
B. The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.
C. A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.
D. Page Layouts should never be deployed via Change Sets, as this causes Field-Level Security to be reset and fields to disappear.

정답：A,C

설명：
