   A startup is moving from a manual deployment process to a container orchestration platform. They have a mix of stateless and stateful services, and they need to automate rolling updates and rollbacks, service discovery, and scaling based on load. Which platform feature set should they prioritize?

   • AImperative commands, a custom scheduler, and a load balancer.
   • BDeclarative configuration, controllers for workloads, and a service mesh.
   • CDeclarative configuration, workload controllers (Deployments/StatefulSets), and built-in service discovery.
   • DA container registry, a monitoring stack, and a CI/CD pipeline.

   A platform team is running a Kubernetes cluster with a mix of critical and non-critical workloads. They want to ensure that during resource contention, critical workloads are not evicted, and that non-critical workloads can be terminated if needed. Which set of configurations should they implement?

   • AAssign higher priority classes to critical workloads and set resource requests and limits for all workloads.
   • BSet resource limits only for non-critical workloads and no limits for critical workloads.
   • CUse the same priority class for all workloads and rely on resource quotas.
   • DUse node selectors to pin critical workloads to dedicated nodes.

   A development team is deploying a microservices application on Kubernetes. The frontend service needs to discover the backend service by a stable DNS name, and the backend service has multiple replicas. The team also wants to ensure that traffic is load-balanced across the backend replicas. Which Kubernetes object should they use?

   • ACreate a headless Service and configure the frontend to use the pod IPs directly.
   • BCreate a ConfigMap that lists the backend pod IPs and mount it into the frontend pods.
   • CCreate a Service of type ClusterIP that selects the backend pods by label.
   • DCreate an Ingress resource that routes traffic to the backend pods based on the host header.

   A large enterprise is designing a Kubernetes platform for multiple business units. Each business unit requires its own set of namespaces, and the security team mandates that each business unit must have its own dedicated control plane to prevent any cross-tenant API access. The platform team wants to minimize operational overhead. Which architecture should they choose?

   • ADeploy a single cluster and use a multi-tenancy operator to create virtual clusters for each business unit.
   • BDeploy a separate cluster for each business unit using a GitOps-based management tool.
   • CDeploy a single shared cluster with strong RBAC and NetworkPolicies to isolate each business unit.
   • DDeploy a single cluster with a separate namespace per business unit and use a service mesh for isolation.
