Preview Questions DevOps | Role Specific Skill

Question 1: Your team is adopting a new cloud-native application platform (e.g., Kubernetes or serverless). How do you adapt your monitoring strategy to ensure comprehensive visibility into the health and performance of this new environment?

Which action should you take?

Choose only one option

Rely on the platform's built-in monitoring and logging capabilities to gather basic metrics and events.

Integrate third-party monitoring tools specifically designed for cloud-native environments to gain deeper insights.

Instrument your applications with distributed tracing and custom metrics to track requests and identify performance bottlenecks across microservices.

Implement a combination of platform-native monitoring, third-party tools, and application instrumentation to achieve comprehensive observability.

Question 2: You are responsible for monitoring a large and complex multi-cloud environment spanning multiple regions and availability zones. How do you ensure efficient and cost-effective monitoring across this distributed environment while maintaining high levels of observability?

Which action should you take?

Choose only one option

Rely solely on cloud-native monitoring services provided by each cloud provider to collect and analyze metrics from various cloud resources, potentially leading to fragmented visibility and increased costs.

Deploy a centralized monitoring solution that can aggregate and correlate data from multiple cloud regions and on-premises environments, providing a unified view of the entire infrastructure.

Implement a multi-layered monitoring approach, combining cloud-native monitoring, third-party tools, and custom instrumentation to gain optimal visibility into different aspects of the system.

Leverage container orchestration platforms like Kubernetes to automate the deployment and management of monitoring agents and exporters across your infrastructure, reducing manual effort and ensuring consistency.

Question 3: Your organization is experiencing significant cost overruns in its cloud infrastructure spending. You are tasked with identifying and implementing cost optimization strategies while maintaining performance and reliability. What approach do you take?

Which action should you take?

Choose only one option

Conduct a thorough cost analysis, leveraging cloud provider billing data and resource utilization metrics, to identify areas of inefficiency and potential cost savings.

Implement cost optimization techniques, such as rightsizing instances, utilizing spot instances, and scheduling resource scaling based on demand patterns.

Review and refactor IaC templates and automation scripts to optimize resource provisioning and eliminate any unnecessary or underutilized resources.

Negotiate with cloud providers for better pricing and discounts, exploring options like reserved instances or committed use discounts for predictable workloads.

Question 4: You've deployed an application to AWS using EC2 instances. You're now seeing intermittent spikes in traffic that cause performance issues. What service could you use to automatically scale your application based on demand?

Which action should you take?

Choose only one option

AWS Elastic Beanstalk

AWS Auto Scaling

AWS Lambda

AWS Elastic Load Balancing

Question 5: You observe a significant increase in container image sizes, impacting build and deployment times and increasing storage costs. How do you optimize image sizes without compromising application functionality or security?

Which action should you take?

Choose only one option

Leverage multi-stage builds to separate build-time dependencies from runtime dependencies, resulting in smaller and more efficient final images.

Utilize minimal base images, such as Alpine Linux or distroless images, to reduce the overall image size and attack surface.

Analyze the contents of images using tools like dive to identify and remove any unnecessary files or dependencies.

Implement image layer caching and reuse strategies to avoid rebuilding unchanged layers, speeding up build times and reducing storage consumption.

Question 6: You want to implement security monitoring for your infrastructure. What tools or techniques would you use?

Which action should you take?

Choose only one option

Set up intrusion detection and prevention systems (IDPS) to monitor network traffic for suspicious activity.

Collect and analyze logs from various systems and applications to identify potential security incidents.

Use security information and event management (SIEM) tools to aggregate and correlate security events from different sources.

All of the above.
