A developer has written an AWS Lambda function. The function is CPU-bound. The developer wants to ensure that the function returns responses quickly.
How can the developer improve the function’s performance?
A . Increase the function’s CPU core count.
B . Increase the function’s memory.
C . Increase the function’s reserved concurrency.
D . Increase the function’s timeout.
Answer: B
Explanation:
The amount of memory you allocate to your Lambda function also determines how much CPU and network bandwidth it gets. Increasing the memory size can improve the performance of CPU-bound functions by giving them more CPU power. The CPU allocation is proportional to the memory allocation, so a function with 1 GB of memory has twice the CPU power of a function with 512 MB of memory.
