Selected Answer: B
Provisioned concurrency addresses this by pre-warming a specified number of function instances, ensuring that these instances are always ready to handle invocations. This reduces the initialization time (cold start) for the Lambda function.

Selected Answer: B
Provisioned concurrency – This is the number of pre-initialized execution environments allocated to your function. These execution environments are ready to respond immediately to incoming function requests. Provisioned concurrency is useful for reducing cold start latencies for functions. Configuring provisioned concurrency incurs additional charges to your AWS account.
