How do OCI DevOps Deployment pipelines reduce the risk and complexity of production applications?

• By eliminating down time of production applications

• By reducing change-driven errors introduced by manual deployments

• By scaling builds with service-managed build runners

• By working with existing Git repositories and CI systems

Answer explanation

OCI (Oracle Cloud Infrastructure) DevOps Deployment pipelines enable teams to automate the deployment process for their applications, reducing the risk and complexity associated with manual deployments. By automating the deployment process, DevOps pipelines reduce the likelihood of change-driven errors and misconfigurations that can occur during manual deployments, which can lead to down time and other issues in production applications.

A software development team has a pipeline set up for their application code, which automatically builds and tests the code on each commit. When the build and test stages are successful, the team deploys the code to a staging environment. However, the deployment to the production environment is done manually after approval from the team lead. Which DevOps practice does this scenario best represent?

• Continuous

  Testing

• Continuous

  Delivery

• Continuous

  Monitoring

• Continuous Development

Answer explanation

Continuous Delivery is a DevOps practice in which the development team ensures that the application code is always ready for deployment to production by automating the build, test, and deployment processes. In the scenario, the development team has already automated the build and test stages and deploys the code to a staging environment automatically. However, the deployment to the production environment is done manually after approval from the team lead, which is a common practice in Continuous Delivery.

As an aspiring Software Designer or Cloud Architect, you want to know more about DevOps as a Service. Which option best describes DevOps as a Service?

• It is a service that operates two separate pipelines concurrently to support multiple development teams.

• It is a service that provides tools and resources for various IT professionals to build and manage cloud-based systems.

• It is a service that primarily focuses on deploying and maintaining cloud infrastructure for System Administrators.

• It is a CI/CD platform that enables developers to automate and streamline their software delivery life cycle.

Answer explanation

DevOps as a Service is a cloud-based service that provides a platform for teams to automate and streamline their software delivery life cycle. It offers tools and resources to support the entire DevOps process, from code development and testing to deployment and monitoring. DevOps as a Service is typically based on a Continuous Integration/Continuous Deployment (CI/CD) model, which enables developers to quickly and efficiently deliver software updates to production environments.

Which of these is not a benefit of using DevOps as a service on Oracle Cloud Infrastructure (OCI)?

• Streamlined communication and collaboration between development and operations teams

• Increased manual intervention for application deployments.

• Reduced infrastructure and maintenance expenses due to automated provisioning and resource management

• Enhanced security and compliance measures for applications and infrastructure

Answer explanation

DevOps aims to enhance collaboration, streamline processes, and accelerate development cycles, ultimately leading to faster delivery of applications to the market. The term "Delayed development progress and prolonged time-to-market for applications" contradicts this fundamental DevOps principle. In a successful DevOps implementation, development progress is expected to be more efficient, leading to shorter time-to-market rather than delays. Thus, this outcome runs counter to the core objectives of DevOps practices.

Which option best describes the DevOps life cycle?

• A rapid-release, multi-phased software development life cycle (SDLC)

• A staggered-release, agile process for software development

• A process of software coding that involves multiple phases and releases

• Only a development process that involves heightened collaboration, culture, and communication

Answer explanation

DevOps is a set of practices that emphasizes collaboration and communication between development and operations teams to deliver software more efficiently and reliably. The DevOps life cycle involves a rapid-release approach to software development, with multiple phases that include planning, development, testing, deployment, and monitoring. The goal of the DevOps life cycle is to ensure that software is delivered quickly, with high quality and reliability, by breaking down silos between teams and automating processes wherever possible.

In software development, various models and methodologies are used to manage the software development process. DevOps is a relatively new methodology that has gained popularity due to its ability to streamline the development and deployment process. With that in mind, of which traditional software development model or methodology is DevOps considered an extension?

• Waterfall model

•  Incremental and Iterative model

• Spiral model

• Agile methodology

Answer explanation

Agile methodology is a traditional software development model that emphasizes flexibility, collaboration, and iterative development. DevOps is often considered an extension of Agile methodology because it shares many of the same values and principles, such as a focus on continuous improvement, frequent feedback, and cross-functional collaboration.
