Why take this course?

  1. Correct Answer: B) To merge all developers' working copies to a shared mainline several times a day.

    Explanation: Infrastructure as Code (IaC) is an important part of modern infrastructure management. It allows for automating the provisioning and configuration of infrastructure through machine-readable definition files, such as scripts written in tools like Terraform, AWS CloudFormation, or Ansible. This ensures consistency across environments and reduces manual errors. Documentation of systems configurations is typically replaced by the code itself, which is kept in version control alongside application code.

  2. Correct Answer: B) A technique where a new version of software is rolled out to a small subset of users initially.

    Explanation: Canary releasing is a strategy used to reduce the risk of negative impacts caused by deploying untested software to all users at once. It involves releasing the new software version to a small group (the "canary" group) and monitoring its performance. If no issues are detected, the release can be gradually rolled out to more users. This approach helps in early detection of potential problems with minimal impact on end-users.

  3. Correct Answer: C) Integrating security practices early in the software development lifecycle.

    Explanation: The concept of 'Shift Left' in DevOps emphasizes integrating security-related concerns, testing, and compliance considerations into the earlier stages of the software development lifecycle (SDLC). This practice aims to identify vulnerabilities or risks as early as possible, ideally during the planning and design phases, so that developers can address them before they become more costly to fix later in the lifecycle.

  4. Correct Answer: D) Shifting the production environment to a cloud-based platform.

    Explanation: Although the term 'Shift Left' is typically associated with integrating security and testing practices earlier, the phase 'Shift to Cloud' refers to a different concept where organizations migrate their applications and infrastructure from on-premises data centers to cloud-based environments. This shift can enable a cloud-native approach, utilizing services like containerization (Kubernetes), serverless computing, and managed databases that are more scalable, resilient, and efficient than traditional setups. It is another key aspect of modern DevOps practices.

  5. Correct Answer: B) A technique where a new version of software is rolled out to a small subset of users initially.

    Explanation: In continuous integration and delivery (CI/CD), a canary release is a strategy used to introduce a new version of software to a select, smaller set of users before rolling it out to everyone. This controlled rollout allows teams to observe the impact of the new release on a limited basis and ensures that any adverse effects are contained and do not affect all users. If the initial release (the "canary") performs as expected, it can be gradually exposed to the entire user base. This technique helps in maintaining application stability and reliability while ensuring that end-users have the most performant and secure version of the software.
