When you run a NoSQL database on Amazon EC2 instances, you are responsible for managing the database layer and the guest operating system of the instances. This means that you need to perform tasks such as updating the operating system, maintaining high availability, and configuring the security group firewall. AWS is responsible for managing the physical infrastructure that hosts the EC2 instances. This means that AWS ensures that the hardware and firmware of the servers, routers, switches, and other devices are updated and secure. AWS also handles the power, cooling, networking, and security of the data centers12. References: CLF-C02: Which task is responsibility of AWS to run NoSQL database on …, Best Practices for Hosting NoSQL Databases on Amazon EC2

AWS Glue is a serverless data integration service designed to discover, prepare, move, and integrate data from multiple sources for data analytics and machine learning purposes. It provides a managed ETL (Extract, Transform, Load) service that is ideal for preparing and transforming data for analytics. AWS Data Exchange is used for finding and subscribing to third-party data, Amazon Athena is for querying data stored in Amazon S3 using SQL, and Amazon EMR is for big data processing using Apache Hadoop and Spark, but AWS Glue is specifically designed for data integration and preparation tasks.

AWS Direct Connectis a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. This requires the use of an Internet Service Provider (ISP) and a colocation facility to connect to the Direct Connect location. It provides a private, high-speed, low-latency connection that does not go over the public internet.

A. AWS VPN: Incorrect, as AWS VPN establishes secure connections over the internet and does not necessarily require a colocation facility.

B. Amazon Connect: Incorrect, as it is a cloud-based contact center service.

D. Internet Gateway: Incorrect, as it is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet.
