Knowledge on other cloud platforms – AWS, GCP etc. SN Responsibility of / Expectations from the Role 1 Requirement gathering and communication with Stakeholders 3 Provide Solution concepts, estimations and integration architecture 4 Streamlining the approach for enhanced cost management 5 Implementing best practices for ensuring cloud security Keyword: Skills: Digital : Cloud DevOps~Digital : Kubernetes Experience Required: 6-8 1. Explain ECS, OSS, VPC and SLB/ALB in Alibaba Cloud. Expected answer: • ECS: Compute/virtual-server service. • OSS: Object-storage service. • VPC: Logically isolated cloud network. • SLB/ALB: Services for distributing incoming traffic across backend workloads. Strong answer: Candidate connects the services into an architecture rather than merely expanding acronyms. ________________________________________ 2. What is Alibaba Cloud ACK and how does it relate to Kubernetes? Expected answer: ACK is Alibaba Cloud's managed Kubernetes offering. It provides Kubernetes-based container orchestration while integrating with Alibaba Cloud infrastructure/services. Candidate should demonstrate hands-on understanding of: • Deployments • Services • Pods • Scaling • Networking • Storage • RBAC • Troubleshooting ________________________________________ 3. A pod in ACK is stuck in Pending. How would you troubleshoot it? Expected answer: Check pod events and scheduling information first. Possible areas include: • Insufficient CPU/memory • Node availability • Scheduling constraints • Taints/tolerations • Storage/PVC issues • Quotas or policies Strong answer: Candidate starts with events/description rather than repeatedly restarting the workload. ________________________________________ 4. A pod keeps going into CrashLoopBackOff. What would you check? Expected answer: • Container/application logs • Previous container logs • Exit reason/code • Kubernetes events • Environment/configuration • Secrets • Application dependencies • Health probes • Resource limits • Application start-up behaviour Red flag: Candidate says "delete the pod and Kubernetes will recreate it” without investigating the root cause. ________________________________________ 5. Explain Kubernetes Service, Ingress and Load Balancer. Expected answer: • Service: Provides stable network access to a set of pods. • LoadBalancer: Exposes suitable services using an external load balancer. • Ingress: Provides HTTP/HTTPS routing rules to services through an ingress controller. Strong answer: Candidate can explain how external traffic reaches an application running inside ACK. ________________________________________ 6. What is Kubernetes RBAC and how would you secure cluster access? Expected answer: RBAC controls what users and service accounts are authorised to perform against Kubernetes resources. Look for: • Roles • ClusterRoles • RoleBindings • ClusterRoleBindings • Service accounts • Namespace isolation • Least privilege ________________________________________ 7. Explain how you would build a CI/CD pipeline for a containerised application. Expected answer: A solid pipeline might follow: Commit → Build → Test → Security checks → Build image → Push image → Deploy → Validate/monitor Strong answer: Candidate covers rollback, versioning, approvals and environment promotion rather than just build/deploy. ________________________________________ 8. What problem does Helm solve in Kubernetes? Expected answer: Helm provides packaging and templating for Kubernetes applications. A chart can package resources such as: • Deployments • Services • ConfigMaps • Ingress • Other Kubernetes configuration Values can then be customised across different environments. Strong answer: Candidate has used Helm for real development/test/production deployments and understands release/version management. ________________________________________ 9. How would you use Terraform with Alibaba Cloud? Expected answer: Terraform can declaratively define and manage infrastructure. A strong practical answer should discuss: • Providers • Resources • Variables • Modules • State • Environment configuration • Version control • CI/CD integration • Secure handling of credentials Example infrastructure could include networking, compute, storage and Kubernetes-related cloud resources. ________________________________________ 10. An ACK-hosted production application suddenly becomes slow. How would you troubleshoot it? Expected answer: Use a layered approach: Application → Pod → Kubernetes → Network → Cloud infrastructure → Dependencies Check: • Application latency/errors • Pod CPU/memory • Restarts • Resource throttling • Replica count • Node utilisation • Network/connectivity • Load-balancing behaviour • Downstream dependencies • Logs and metrics Comments for Suppliers: Rate Details Rate Card Class: IND_Developer Category: Category 4 Level: Level II Bill Rate: Rs70,000.00 - Rs130,000.00 Monthly NOOT Markup: $0.00 Other Estimated Expenses: Type Amount No items to display.
