A company is setting up a big data analytics cluster on AWS, utilizing numerous Linux Amazon EC2 instances distributed across multiple Availability Zones. To ensure efficient data processing, all cluster nodes require both read and write access to a shared file storage system. This storage system must be highly available, resilient, POSIX-compatible, and capable of handling significant throughput. Which AWS storage solution best meets these stringent requirements?

To ensure efficient data processing, all cluster nodes require both read and write access to a shared file storage system. This storage system must be highly available, resilient, POSIX-compatible, and capable of handling significant throughput. Which AWS storage solution best meets these stringent requirements?
Explanation:
The correct answer is D. Amazon Elastic File System (EFS) with Max I/O performance mode is specifically designed to handle high levels of throughput and can support the requirements of big data analytics workloads. While the General Purpose performance mode (answer B) is suitable for latency-sensitive applications, Max I/O mode (answer D) is optimized for environments that demand high aggregate throughput and high operations per second. This makes option D the most appropriate choice for a highly available, resilient, POSIX-compatible, and high-throughput file storage solution across multiple EC2 instances in different Availability Zones.
