Preview Questions DevOps | Role Specific Skill

Question 1: Your team is adopting a new configuration management tool to replace an existing legacy system. How do you ensure a smooth transition and minimize disruption to ongoing operations?

Which action should you take?

Choose only one option

Conduct a thorough evaluation of the new tool's capabilities and compatibility with existing infrastructure and processes.

Develop a detailed migration plan, including data migration, configuration conversion, and testing procedures.

Provide comprehensive training and support to team members on the new tool and its workflows.

Gradually phase out the legacy system, starting with non-critical components and closely monitoring the impact.

Question 2: You're setting up a new web application. How do you protect it from common web vulnerabilities like SQL injection and cross-site scripting (XSS)?

Which action should you take?

Choose only one option

Use a web application firewall (WAF) to filter and block malicious traffic.

Implement input validation and sanitization on both the client-side and server-side.

Keep the application and its dependencies up-to-date with the latest security patches.

All of the above.

Question 3: A security vulnerability is discovered in a third-party library used in your application. How do you respond and ensure the security of your CI/CD pipeline?

Which action should you take?

Choose only one option

Update the library to the latest version and re-run the pipeline to ensure compatibility.

Conduct a thorough security assessment to identify and mitigate any potential risks associated with the vulnerability.

Implement automated security scanning tools in the pipeline to detect vulnerabilities in dependencies.

Temporarily disable the affected functionality until a patch or fix is available.

Question 4: You notice that configuration changes are taking a long time to propagate across your infrastructure, impacting deployment times. How do you improve the speed and efficiency of configuration management?

Which action should you take?

Choose only one option

Optimize your configuration management tool's settings and configurations for better performance.

Break down large configuration files into smaller, more manageable modules to reduce processing time.

Implement a distributed configuration management architecture to parallelize configuration application across multiple servers.

Cache configuration data on managed servers to minimize network traffic and reduce latency.

Question 5: During a security audit, it is found that some sensitive data is stored in plain text in a configuration file. How do you rectify this?

Which action should you take?

Choose only one option

Encrypt the sensitive data and store the encryption key securely.

Restrict access to the configuration file to authorized personnel only.

Move the sensitive data to a more secure location, like a secrets management tool.

Obfuscate the sensitive data using a simple encoding scheme.

Question 6: You are tasked with improving the security posture of your IaC infrastructure and preventing potential breaches or misconfigurations. What strategies do you implement to achieve this goal?

Which action should you take?

Choose only one option

Integrate security scanning and vulnerability assessment tools into your CI/CD pipeline to identify and address security issues early in the development process.

Utilize policy-as-code frameworks to enforce security best practices and compliance standards during infrastructure provisioning and configuration changes.

Implement secrets management solutions to securely store and manage sensitive configuration data, such as API keys, passwords, and certificates.

Regularly conduct security audits and penetration testing to identify and remediate vulnerabilities in your IaC infrastructure.
