Preview Questions DevOps | Role Specific Skill

Question 1: You've deployed a database to Azure SQL Database. You want to ensure high availability and disaster recovery for your database. What feature or service would you use?

Which action should you take?

Choose only one option

Azure Backup

Azure Site Recovery

Azure SQL Database geo-replication

Azure Availability Zones

Question 2: You are leading a team that is adopting a GitOps approach to managing infrastructure and application deployments. How do you ensure a smooth transition and successful implementation?

Which action should you take?

Choose only one option

Define clear Git workflow policies and branching strategies to manage changes effectively.

Implement automated synchronization mechanisms to ensure consistency between Git repositories and the deployed environment.

Provide comprehensive training and support to team members on GitOps principles and practices.

Start with a small pilot project to test the GitOps approach and gather feedback before wider adoption.

Question 3: You need to securely store and manage sensitive configuration data, such as database credentials or API keys, for your containerized applications. What is the best practice for handling this information?

Which action should you take?

Choose only one option

Store sensitive data as environment variables within the container, ensuring they are not exposed in container logs or configuration files.

Utilize Kubernetes Secrets or similar mechanisms to store sensitive data securely and make them accessible to containers at runtime.

Encrypt sensitive data and store it in a separate configuration file mounted as a volume within the container.

Hardcode sensitive data directly into the application code, ensuring it's obfuscated or encrypted to prevent unauthorized access.

Question 4: You are deploying a containerized application to a production environment, but you want to minimize downtime and ensure a smooth rollout. What deployment strategy do you choose to achieve this?

Which action should you take?

Choose only one option

Blue-green deployment, where you deploy the new version alongside the old version and then switch traffic once the new version is validated.

Canary deployment, where you gradually roll out the new version to a small subset of users and monitor its performance before expanding the rollout.

Rolling deployment, where you update containers one by one, ensuring minimal downtime but potentially exposing users to intermediate states.

Recreate deployment, where you terminate all existing pods and create new ones with the updated container image, leading to a brief downtime.

Question 5: You're deploying a new application version to production. What monitoring strategies would you implement to ensure a smooth rollout?

Which action should you take?

Choose only one option

Set up synthetic monitoring to simulate user interactions and proactively detect issues.

Monitor application logs and metrics for errors, exceptions, and performance degradation.

Implement real-user monitoring (RUM) to track actual user experience and identify potential problems.

All of the above.

Question 6: You are responsible for securing your organization's cloud infrastructure and data. What best practices and cloud services do you implement to protect against unauthorized access and potential breaches?

Which action should you take?

Choose only one option

Enforce strong authentication and authorization mechanisms, such as multi-factor authentication and role-based access control, to restrict access to cloud resources.

Encrypt sensitive data at rest and in transit using encryption services provided by your cloud provider or third-party solutions.

Implement network security controls, such as firewalls, security groups, and network segmentation, to protect your cloud infrastructure from external threats.

Regularly conduct security audits and vulnerability assessments to identify and address potential weaknesses in your cloud environment.
