Correct Answer: Conducting automated security scans during code commits

The 'shift left' testing approach in DevOps emphasizes moving testing activities earlier in the software development lifecycle (SDLC). Conducting automated security scans during code commits exemplifies this principle perfectly by integrating security testing at the earliest possible stage - during development. The key aspects that make this the best answer: - Automation enables rapid feedback - Integration at commit time catches issues early - Developers receive feedback while the code is fresh in their minds - Problems are cheaper and easier to fix at this stage Other options are incorrect because: - Running tests after production deployment is the opposite of shift left - it's too late in the process - Manual security audits, while valuable, do not represent the automation and early integration principles of DevOps - Implementing checks at the final deployment stage is again too late in the process and represents traditional 'shift right' testing

Correct Answer: Shared responsibility for code from development to production

In DevOps, shared responsibility for code from development to production is the most effective practice for collaboration because: It creates true ownership and accountability across the entire software delivery pipeline It breaks down traditional silos between teams It encourages cross-functional learning and skill development It promotes unified goals and metrics focused on overall delivery success The other options are incorrect because: Separate metrics and goals create misaligned incentives and perpetuate division between teams Specialized teams focused on their own domains reinforce silos and reduce collaboration opportunities Maintaining clear boundaries contradicts the core DevOps principle of breaking down walls between development and operations The essence of DevOps is integrating development and operations through shared practices, tools, and responsibilities to deliver better software faster.

Correct Answer: Using short-lived feature branches with frequent merges to main

Short-lived feature branches with frequent merges to main is the optimal approach for DevOps success because: - It promotes continuous integration practices - Reduces merge conflicts and integration problems - Enables faster feedback loops - Supports rapid delivery and deployment - Minimizes technical debt - Aligns with DevOps principles of small, incremental changes The other approaches are problematic because: Long-running feature branches create integration challenges, increase merge conflicts, and delay feedback. Separate branches for each team member can lead to coordination issues, excessive merge complexity, and reduced collaboration. Strict branch policies with extensive reviews before merges can create bottlenecks and slow down the delivery pipeline, contradicting DevOps principles of flow and rapid delivery.
