AWS Certified Solutions Architect - Amazon RDS Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

What is the purpose of Amazon RDS Multi-AZ?

To allow cross-region replication To provide automatic database backups To scale out read traffic across multiple nodes To provide high availability and automatic failover

Correct Answer: To provide high availability and automatic failover

Amazon RDS Multi-AZ provides high availability and automatic failover to a standby instance in a different Availability Zone to help protect against data loss and minimize downtime during a planned or unplanned outage.

Question 2

Which of the following is a benefit of using Amazon RDS read replicas?

Improved encryption and security by automatically encrypting all data stored in your Amazon RDS instance. Improved read performance and availability by providing low-latency, scalable read traffic to your application. Improved write performance and availability by automatically increasing the number of write nodes in your cluster. Reduced storage costs by automatically compressing your database backups.

Correct Answer: Improved read performance and availability by providing low-latency, scalable read traffic to your application.

Amazon RDS read replicas allow you to scale your read traffic by creating one or more replicas of your database instance. Replicas can be added in slave mode to any Amazon RDS database engine that supports replication. The replicas enable low-latency, scalable read traffic by enabling read traffic to be offloaded from the primary database instance, offering improved read performance and availability to your application.

Question 3

What is the purpose of an Amazon RDS event subscription?

To adjust database instance settings To create read replicas To configure database backups To receive notifications for specific RDS events

Correct Answer: To receive notifications for specific RDS events

Amazon RDS event subscriptions allow you to receive notifications for specific events such as database creation, deletion, or modification, instance status changes, or scheduled maintenance. This can help you stay informed about important activities and take action accordingly.
