Implementing Azure DevOps Solutions

By: Henry Been, Maik van der Gaag

Overview of this book

Implementing Azure DevOps Solutions helps DevOps engineers and administrators to leverage Azure DevOps Services to master practices such as continuous integration and continuous delivery (CI/CD), containerization, and zero downtime deployments. This book starts with the basics of continuous integration, continuous delivery, and automated deployments. You will then learn how to apply configuration management and Infrastructure as Code (IaC) along with managing databases in DevOps scenarios. Next, you will delve into fitting security and compliance with DevOps. As you advance, you will explore how to instrument applications, and gather metrics to understand application usage and user behavior. The latter part of this book will help you implement a container build strategy and manage Azure Kubernetes Services. Lastly, you will understand how to create your own Azure DevOps organization, along with covering quick tips and tricks to confidently apply effective DevOps practices. By the end of this book, you’ll have gained the knowledge you need to ensure seamless application deployments and business continuity.

Implementing Application Infrastructure

  1. You are working on an application that will be deployed in two different Azure Regions to allow for failover scenarios. Which of the following together make a valid solution? [Choose two.]
    1. You create one ARM template with two parameter files. The first parameter file corresponds to the first Azure region, and the second parameter file to the second Azure region. You use the ARM templates to update the infrastructure.
    2. You create an ARM template and parameter file to update the infrastructure in one region only. In the other region, you update the infrastructure manually to prevent configuration drift.
    3. You first update the infrastructure in both regions. Only when the infrastructure is updated successfully do you deploy the application to both regions.
    4. You first update the infrastructure in one region, followed by a deployment of the application...
