                                                    NEW QUESTION # 98
                                                    You are implementing a continuous integration and continuous deployment (CI/CD) pipeline for a cloud native application running in Kubernetes. Which of the following tools can be used for building, testing, and deploying the application to the cluster?

                                                    Answer: A,B,C,D,E

                                                    Explanation:
                                                    All of the listed tools are widely used for CI/CD pipelines and can be integrated with Kubernetes. Each tool has its own strengths and weaknesses depending on your specific needs. Here's a brief overview: Jenkins: Open-source, highly customizable, and supports a wide range of plugins. CircleCl: Cloud-based, user-friendly, and well-suited for smaller teams and projects. Travis Cl: Also cloud-based, popular for open-source projects and known for its simple setup. GitHub Actions: Native to GitHub, allows you to build, test, and deploy directly within your repository. GitLab CI/CD: Integrated with GitLab, provides a complete CI/CD solution with features for building, testing, and deploying applications.


                                                    NEW QUESTION # 99
                                                    What is a best practice to minimize the container image size?

                                                    Answer: A

                                                    Explanation:
                                                    A proven best practice for minimizing container image size is to use multi-stage builds, so B is correct. Multi-stage builds allow you to separate the "build environment" from the "runtime environment." In the first stage, you can use a full-featured base image (with compilers, package managers, and build tools) to compile your application or assemble artifacts. In the final stage, you copy only the resulting binaries or necessary runtime assets into a much smaller base image (for example, a distroless image or a slim OS image). This dramatically reduces the final image size because it excludes compilers, caches, and build dependencies that are not needed at runtime.
                                                    In cloud-native application delivery, smaller images matter for several reasons. They pull faster, which speeds up deployments, rollouts, and scaling events (Pods become Ready sooner). They also reduce attack surface by removing unnecessary packages, which helps security posture and scanning results. Smaller images tend to be simpler and more reproducible, improving reliability across environments.
                                                    Option A is not a size-minimization practice: using a Dockerfile is simply the standard way to define how to build an image; it doesn't inherently reduce size. Option C (different tags) changes image identification but not size. Option D (a build script) may help automation, but it doesn't guarantee smaller images; the image contents are determined by what ends up in the layers.
                                                    Multi-stage builds are commonly paired with other best practices: choosing minimal base images, cleaning package caches, avoiding copying unnecessary files (use .dockerignore), and reducing layer churn. But among the options, the clearest and most directly correct technique is multi-stage builds.
                                                    Therefore, the verified answer is B.


                                                    NEW QUESTION # 100
                                                    What is the purpose of the 'kubelet* component in Kubernetes?

                                                    Answer: A

                                                    Explanation:
                                                    The "kubelet• component in Kubernetes is responsible for running and managing containers on each node. It is the agent that communicates with the master and ensures that Pods are running as intended. Option 'A' is incorrect because that is the role of the kube-proxy and the API server. Option 'B' is incorrect because scheduling is handled by the scheduler. Option 'D' is incorrect because that is the role of the API server. Option 'E' is incorrect because configuration and state are managed by the etcd.


                                                    NEW QUESTION # 101
                                                    Your application relies on a backend database service. Using Istio, you want to configure a circuit breaker pattern to prevent cascading failures if the database becomes unresponsive. How would you implement this?

                                                    Answer: A

                                                    Explanation:
                                                    Istio's VirtualService and DestinationRule features allow you to configure fallback services. In the case of the database being unavailable, you can define a fallback service or mechanism to handle the request. Option B helps test circuit breaker behavior but doesn't implement it. Option C could be used for retries, but doesn't address the circuit breaker pattern. Option D is related to request timeouts, not circuit breaking. Option E is a manual approach, while Istio provides a more integrated solution.

                                                    What does the 'kops' acronym means?

                                                    Answer: C
