C. Increase the function’s reserved concurrency. Reserved concurrency is a feature in AWS Lambda that allows you to allocate a specific amount of concurrency to a particular function. This ensures that the function has a dedicated amount of concurrency and is not affected by throttling due to high usage of other functions in your account. Increasing the reserved concurrency can help mitigate throttling issues, especially if the throttling is due to reaching account-level concurrency limits. E. Request a service quota change for increased concurrency. AWS Lambda has default service quotas (formerly known as limits) for the maximum number of concurrent executions across all functions in your account. If your Lambda function is experiencing throttling due to reaching these account-level concurrency limits, requesting an increase in the service quota for Lambda concurrency can provide a solution.

C. Increase the function’s reserved concurrency: Reserved concurrency ensures that a specific number of concurrent executions are always available for your function. E. Request a service quota change for increased concurrency: If your application is experiencing throttling and the reserved concurrency isn't sufficient, you can request a service quota increase for additional concurrency.
