The company wants to ensure the API's Lambda function operate without being affected by other Lambda functions. Which solution will meet this requirement MOST cost-effectively?
Options
- AIncrease the number of read capacity unit (RCU) in DynamoDB.
- BConfigure provisioned concurrency for the Lambda function.
- CConfigure reserved concurrency for the Lambda function.
