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. 2 and 4

The Neptune VPC endpoint won't be used to import from S3.

You do need an S3 endpoint, so this is correct.

The EC2 does need to access S3, so this isn't correct.

Neptune will need an IAM role to access S3, so this is correct.

S3 will not be reading from Neptune so it does not need an IAM role.

  1. 3

You cannot delete from Timestream, so that is the only correct answer.

  1. 4

QLDB only supports 20 tables, so you have hit the maximum allowed.

  1. 1 and 5

Gremlin and SPARQL are the only languages supported by Neptune.

  1. 1

The _ql_committed tables show all the history for any modifications, and this is the correct answer.
