Selected Answer: B
Option B: Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day. Explanation: Provisioned concurrency ensures that a specified number of Lambda instances are initialized and ready to handle requests. By scheduling this scaling, you can pre-warm Lambda functions before peak usage times, reducing cold start latency. This solution directly addresses the latency issue caused by cold starts.

Selected Answer: B
Provisioned concurrency pre-initializes execution environments for your functions. These execution environments are prepared to respond immediately to incoming function requests at start of day.

Selected Answer: B
Provisioned Concurrency incurs additional costs, so it is cost-efficient to use it only when necessary. For example, early in the morning when activity starts, or to handle recurring peak usage.
