AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A Solutions Architect needs to determine the ideal memory allocation for a new AWS Lambda function that processes short bursts of data with low to moderate processing requirements. What should the Architect consider when selecting the Lambda function's memory size?
Allocate memory size based solely on the duration of the function's execution, regardless of processing requirements.
Choose a lower memory size that still provides adequate CPU power for the function's requirements, balancing cost and performance.
Select the lowest memory size since the function only processes short bursts of data.
Allocate the highest memory option to ensure the fastest execution time.
The correct answer understands that adjusting the memory size also affects the CPU available to the Lambda function, allowing it to complete execution faster. Thus, for moderate processing requirements, it is not necessary to allocate the highest option, but the Architect should choose a memory size that provides sufficient CPU for efficient execution while avoiding unnecessary costs associated with overprovisioning.
