- b: DTR does not manage images' data with high availability. Deploying more than one replica will provide high availability for DTR's processes. DTR replication requires data sharing between replicas, but we must include third-party solutions to provide high availability for our storage.
- a and b: The DTR installation runs the dtr-garant and dtr-jobrunner containers. The first will manage user authentication, while jobrunner will execute DTR's maintenance tasks to remove unreferenced layers. dtr-notary-server and dtr-notary-signer will be deployed within DTR to manage Docker Content Trust metadata.

Overview of this book
Developers have changed their deployment artifacts from application binaries to container images, and they now need to build container-based applications as containers are part of their new development workflow. This Docker book is designed to help you learn about the management and administrative tasks of the Containers as a Service (CaaS) platform.
The book starts by getting you up and running with the key concepts of containers and microservices. You'll then cover different orchestration strategies and environments, along with exploring the Docker Enterprise platform. As you advance, the book will show you how to deploy secure, production-ready, container-based applications in Docker Enterprise environments. Later, you'll delve into each Docker Enterprise component and learn all about CaaS management. Throughout the book, you'll encounter important exam-specific topics, along with sample questions and detailed answers that will help you prepare effectively for the exam.
By the end of this Docker containers book, you'll have learned how to efficiently deploy and manage container-based environments in production, and you will have the skills and knowledge you need to pass the DCA exam.
