Question 370
An enterprise architecture team faces this design requirement: A shared EFS file system slows a data-processing batch even though compute workers are mostly idle. What should the solutions architect recommend?
Explanation
Correct Answer
EFS throughput characteristics must match concurrent IO patterns and required sustained rate. The required architecture outcome is: A shared EFS file system slows a data-processing batch even though compute workers are mostly idle. Validate this choice by checking that File-system throughput reaches target under representative concurrent processing without exhausted credits.
Incorrect Answers
Every static asset fetch goes to a distant origin instead of the edge cache. The specific problem here is that the shared file system's throughput mode or credit availability constrains parallel clients.
The function's unqualified ARN always invokes latest code for all users, bypassing version routing. The specific problem here is that the shared file system's throughput mode or credit availability constrains parallel clients.
Stream shard limits or skewed partition keys cannot handle incoming record throughput. The specific problem here is that the shared file system's throughput mode or credit availability constrains parallel clients.
