Overview of this book

The AWS Certified Database – Specialty certification is one of the most challenging AWS certifications. It validates your comprehensive understanding of databases, including the concepts of design, migration, deployment, access, maintenance, automation, monitoring, security, and troubleshooting. With this guide, you'll understand how to use various AWS databases, such as Aurora Serverless and Global Database, and even services such as Redshift and Neptune. You’ll start with an introduction to the AWS databases, and then delve into workload-specific database design. As you advance through the chapters, you'll learn about migrating and deploying the databases, along with database security techniques such as encryption, auditing, and access controls. This AWS book will also cover monitoring, troubleshooting, and disaster recovery techniques, before testing all the knowledge you've gained throughout the book with the help of mock tests. By the end of this book, you'll have covered everything you need to pass the DBS-C01 AWS certification exam and have a handy, on-the-job desk reference guide.

  1. 3

Creating a multi-AZ deployment with another read replica works, but it isn't the most cost-efficient.

Moving to EC2 is not a valid solution.

Creating a multi-AZ read replica is a cost-effective and highly-available solution, and is correct.

Creating two single-AZ read replicas is not highly available.

  1. 4

RDS only supports multi-AZ in the same region.

Aurora Global Tables will work, but this is the incorrect process, as you need read replicas.

Deploying MySQL in two regions will not work as there is no replication.

Global tables will work and it uses read replicas, so this is the correct answer.

  1. 2

Aurora does not fully meet the needs of this scenario.

Aurora Serverless will meet the needs of the temporary nature of the application.

RDS does not fully meet the needs of this scenario.

MySQL on EC does not fully meet the needs of this scenario.
