Mixed Deck — All CDP Topics Flashcards

Which Kubernetes resource allows you to expose a set of pods as a network service with a stable DNS name?

Answer: Service

A Kubernetes Service provides a stable IP address and DNS name that abstracts access to a dynamic set of pods.

What is the primary advantage of using container registries in a DevOps pipeline?

Answer: They provide a centralized store for versioned, shareable container images

Container registries serve as a central repository for storing, versioning, and distributing container images across teams and environments.

What is the primary risk of having a high percentage of end-to-end tests and few unit tests (an inverted testing pyramid)?

Answer: Slow, brittle, and expensive test suites that delay pipeline feedback

An inverted pyramid (ice cream cone anti-pattern) results in slow test runs, frequent flaky failures, and high maintenance costs because E2E tests are fragile and resource-intensive.

In DevOps, what is the purpose of a retrospective meeting?

Answer: To review and improve team processes.

In DevOps, a retrospective meeting is a regular event where the team reflects on a past iteration or project to identify what went well, what could be improved, and how to implement those improvements. Its primary purpose is to foster continuous learning and optimize team processes, rather than focusing on individual blame.

Which testing framework is commonly used for behavior-driven development (BDD) in DevOps pipelines?

Answer: Cucumber

Cucumber enables BDD by allowing teams to write tests in Gherkin (Given/When/Then) syntax, bridging communication between technical and non-technical stakeholders.

What is the purpose of a feature flag in a deployment pipeline?

Answer: To enable or disable features at runtime without redeploying

Feature flags allow teams to toggle features on or off at runtime, decoupling code deployment from feature release.

What is the main benefit of using an artifact repository such as Nexus or Artifactory?

Answer: Centralizing versioned build artifacts for consistent deployments

Artifact repositories store and version built artifacts so every deployment uses the exact same tested binary, ensuring consistency.

What is 'release orchestration' in a DevOps context?

Answer: Coordinating and managing the end-to-end release process across teams and environments

Release orchestration tools coordinate complex multi-team, multi-environment release workflows including approvals, timing, and dependencies.

What is the MOST effective way to stay current with developments in implementation & configuration for Certified DevOps Practitioner?

Answer: Participating in professional development, industry events, and peer collaboration

A multi-faceted approach including formal development, industry events, and peer collaboration provides the broadest perspective on current developments.

Which factor MOST impacts the usefulness of documentation & best practices outputs in Certified DevOps Practitioner?

Answer: Timeliness, accuracy, and relevance to the intended audience

Information is most useful when it is timely, accurate, and relevant to the needs of the people who will use it.

What is the PRIMARY benefit of standardizing system architecture & design practices in Certified DevOps Practitioner?

Answer: Consistency, easier maintenance, and improved collaboration among team members

Standardization promotes consistency across the organization, simplifies maintenance, and enables better collaboration between team members.

Which competency is MOST essential for professionals working in implementation & configuration in Certified DevOps Practitioner?

Answer: Critical thinking combined with practical application of knowledge

Critical thinking allows professionals to apply knowledge effectively in varied situations, leading to better outcomes than rote procedures.

What is the PRIMARY objective of security & access control within the Certified DevOps Practitioner profession?

Answer: To ensure quality outcomes through standardized practices and continuous improvement

The primary objective is ensuring quality outcomes through established standards while continuously improving practices and processes.

In a DevOps container pipeline, what is the recommended practice for tagging Docker images pushed to production?

Answer: Use immutable version tags such as git commit SHA or semantic version

Immutable tags like commit SHA or semantic versions ensure reproducibility and prevent silent overwrites that occur with mutable tags like `latest`.

In Docker, what is the primary purpose of a multi-stage build?

Answer: To reduce the final image size by separating build and runtime environments

Multi-stage builds allow you to use multiple FROM instructions, copying only necessary artifacts to the final image, resulting in smaller, leaner production images.

What Kubernetes concept allows pods to request a specific amount of CPU and memory resources?

Answer: Resource requests and limits

Resource requests define the minimum resources a container needs, while limits define the maximum it can consume, enabling the scheduler to place pods appropriately.

Which of the following is a best practice in CI regarding code commits?

Answer: Commit small, frequent changes.

A best practice in Continuous Integration regarding code commits is to commit small, frequent changes. This approach minimizes the risk of complex merge conflicts, makes it easier to pinpoint and fix bugs, and ensures that the main codebase is always in a relatively stable and working state, facilitating continuous feedback.

Which artifact versioning strategy is most commonly recommended for CDP exam release pipelines?

Answer: Semantic versioning (SemVer)

Semantic versioning (MAJOR.MINOR.PATCH) provides clear intent about the nature of changes and compatibility.

Which deployment approach minimizes downtime by incrementally replacing old instances with new ones?

Answer: Rolling deployment

Rolling deployment replaces instances one at a time (or in batches), keeping the application available throughout the update.

What is the PRIMARY benefit of continuous improvement in data management & integration for Certified DevOps Practitioner?

Answer: Enhanced efficiency, quality, and competitive advantage over time

Continuous improvement systematically enhances efficiency and quality, leading to sustained competitive advantage.
