Preview Questions DevOps | Role Specific Skill

Question 1: You are leading a team responsible for monitoring a critical production system with stringent Service Level Objectives (SLOs). How do you ensure that your monitoring strategy aligns with these SLOs and enables you to proactively identify and address potential risks?

Which action should you take?

Choose only one option

Define clear Service Level Indicators (SLIs) that directly reflect the user experience and align with the defined SLOs.

Implement real-time monitoring and alerting based on the SLIs, with thresholds and escalation procedures in place to trigger timely action when SLOs are at risk of being breached.

Conduct regular performance testing and capacity planning exercises to ensure that the system can handle expected workloads and maintain SLO compliance.

Continuously analyze monitoring data and identify trends or patterns that could indicate potential issues, allowing for proactive remediation before SLOs are impacted.

Question 2: You are responsible for securing container images and ensuring they are free from vulnerabilities. What strategies do you implement to achieve this?

Which action should you take?

Choose only one option

Regularly scan container images using vulnerability scanning tools like Clair or Trivy to identify and address known security issues.

Implement image signing and verification processes to ensure the integrity and authenticity of container images.

Enforce strict access controls and image promotion policies to prevent unauthorized modifications or deployments of container images.

Utilize a secure container registry to store and manage container images, ensuring they are protected from unauthorized access or tampering.

Question 3: You notice a significant increase in build times. What's your approach to investigate?

Which action should you take?

Choose only one option

Analyze the build logs to identify any bottlenecks or performance issues.

Profile the build process to pinpoint the most time-consuming steps.

Optimize the build scripts and configurations to improve efficiency.

Upgrade the build infrastructure to handle the increased load.

Question 4: You are leading a team responsible for managing a complex multi-cloud environment with workloads running on AWS, Azure, and GCP. You observe inconsistencies in resource provisioning, configuration management, and security policies across different cloud providers. How do you address this challenge and ensure consistency and governance across your multi-cloud infrastructure?

Which action should you take?

Choose only one option

Develop a custom cloud management platform (CMP) that abstracts cloud-specific complexities and provides a unified interface for managing resources and policies across different providers.

Leverage a cloud-agnostic configuration management tool that supports multiple cloud providers and offers built-in policy enforcement capabilities.

Implement a policy-as-code framework, such as Open Policy Agent (OPA), to define and enforce consistent policies and governance rules across all cloud environments.

Adopt a combination of cloud-specific management tools and a central orchestration layer to manage resources and policies across different providers, ensuring interoperability and consistency.

Question 5: You are experiencing intermittent network latency issues between your application components deployed across multiple regions in the cloud. How do you diagnose and resolve this problem?

Which action should you take?

Choose only one option

Utilize network monitoring tools and services provided by your cloud provider to analyze network traffic patterns and identify potential bottlenecks or congestion points.

Implement a global load balancer or content delivery network (CDN) to distribute traffic across regions and optimize network routing for improved performance.

Leverage network peering or dedicated connections between regions to reduce latency and improve network throughput for inter-region communication.

Optimize application code and data access patterns to minimize network traffic and reduce dependencies on cross-region communication.

Question 6: You are working on a project that requires running multiple containerized applications with complex dependencies and network configurations. How do you manage and orchestrate these containers efficiently?

Which action should you take?

Choose only one option

Manually create and manage individual containers using Docker commands, ensuring proper network configuration and inter-container communication.

Utilize Docker Compose to define and manage multi-container applications with complex dependencies and network topologies.

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

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