Question 1

A gaming company is using an Amazon RDS database for their game's backend. They need to minimize downtime for application updates and planned maintenance events. What should they do?

Use Amazon S3 to store the database and snapshots. Create an AWS Lambda function to automate backups of the database. Enable Multi-AZ deployment for the Amazon RDS instance. Use Amazon ElastiCache to manage the RDS instance.

Correct Answer: Enable Multi-AZ deployment for the Amazon RDS instance.

A Multi-AZ deployment on RDS provides a standby replica in another Availability Zone, which automatically synchronizes data and minimizes downtime. Other options can enhance other aspects, but they don't address the downtime issue.

Question 2

Amazon EBS. Amazon RDS. Amazon S3. Amazon EC2 instance store.

Correct Answer: Amazon S3.

Amazon S3 is the most cost-effective storage service, which provides high durability, availability, and scalability. It is best suited for hosting media files such as videos, images, and other static assests.

Correct Answer: Amazon Kinesis Data Analytics.

Amazon Kinesis Data Analytics is designed for real-time analysis of streaming data with sub-second latencies. Other services are meant for data analysis or processing, but none focus specifically on real-time data streams with such low latency requirements.
