Preview Questions DevOps | Role Specific Skill

Question 1: You notice a performance degradation in your infrastructure after deploying a new IaC configuration. How do you troubleshoot and resolve the issue?

Which action should you take?

Choose only one option

Roll back the IaC changes to the previous known working state and investigate the issue in a staging environment.

Analyze infrastructure monitoring and logging data to identify the root cause of the performance degradation.

Use IaC tools to provision additional resources or scale up existing ones to handle the increased load.

Temporarily disable or modify the newly deployed IaC configuration to isolate the problematic component.

Question 2: 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 3: Your organization is adopting a multi-cloud strategy and you need to design a containerization solution that can seamlessly deploy and manage applications across different cloud providers and on-premises infrastructure. How would you approach this challenge?

Which action should you take?

Choose only one option

Leverage a container orchestration platform like Kubernetes that supports multi-cloud deployments and provides a unified interface for managing containers across different environments.

Utilize a cloud-agnostic container runtime like Docker or containerd that can run on any cloud provider or on-premises infrastructure.

Build custom tooling and automation to manage container deployments and orchestration across different cloud providers, ensuring consistency and portability.

Adopt a hybrid approach, leveraging different container orchestration platforms and tools for specific cloud providers or on-premises environments, while ensuring interoperability through a central management layer.

Question 4: Your team is migrating a legacy monolithic application to a microservices architecture using containers. You are facing challenges managing the increasing complexity of container orchestration and inter-service communication. What approach do you take to address this?

Which action should you take?

Choose only one option

Implement a service mesh like Istio or Linkerd to manage service discovery, traffic routing, and observability across microservices.

Adopt a container orchestration platform like Kubernetes to automate deployment, scaling, and management of containerized microservices.

Refactor the application further to reduce inter-service dependencies and simplify communication patterns.

Introduce API gateways or message queues to decouple microservices and manage communication flows.

Question 5: You are migrating a large legacy application to a cloud-native architecture using IaC. How do you ensure a smooth and successful migration?

Which action should you take?

Choose only one option

Develop a comprehensive migration plan with detailed steps and timelines, including testing and validation procedures.

Break down the application into smaller, manageable components and migrate them incrementally to minimize disruption.

Utilize IaC tools to automate the provisioning and configuration of cloud resources required for the new architecture.

Establish a robust rollback strategy to quickly revert to the previous state in case of unexpected issues during migration.

Question 6: You're using Azure Blob Storage to store large amounts of unstructured data. You need to control access to this data based on user roles and permissions. What service would you use to manage access?

Which action should you take?

Choose only one option

Azure Active Directory

Azure Role-Based Access Control (RBAC)

Azure Key Vault

Azure Security Center
