\"\ud83d\udd39\" Basic Google GKE Interview Questions<\/h3>\n\n\n\n
    \n
  1. What is Google Kubernetes Engine (GKE)?<\/strong>
    GKE is a managed Kubernetes service by Google Cloud that automates cluster management, scaling, and upgrades.<\/li>\n\n\n\n
  2. How does GKE differ from self-managed Kubernetes?<\/strong>
    GKE automates node management, security patches, and monitoring, while self-managed clusters require manual setup and maintenance.<\/li>\n\n\n\n
  3. What are the components of a GKE cluster?<\/strong>\n
      \n
    • Control Plane:<\/strong> Manages cluster operations.<\/li>\n\n\n\n
    • Nodes:<\/strong> Compute instances that run workloads.<\/li>\n\n\n\n
    • Pods:<\/strong> The smallest deployable units containing containers.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n

      \"\ud83d\udd39\" Intermediate Questions<\/h3>\n\n\n\n
        \n
      1. How do you perform autoscaling in GKE?<\/strong>
        GKE supports Cluster Autoscaler<\/strong> and Horizontal Pod Autoscaler (HPA)<\/strong> to adjust resources dynamically based on load.<\/li>\n\n\n\n
      2. Explain node pools in GKE.<\/strong>
        Node pools group nodes with identical configurations for easier management and workload optimization.<\/li>\n\n\n\n
      3. How does GKE handle networking?<\/strong>
        It uses VPC-native clusters<\/strong>, IP aliasing<\/strong>, and Network Policies<\/strong> for secure communication between pods and services.<\/li>\n\n\n\n
      4. What are taints and tolerations in Kubernetes?<\/strong>
        They control which pods can be scheduled on specific nodes by defining scheduling rules and restrictions.<\/li>\n<\/ol>\n\n\n\n
        \n\n\n\n

        \"\ud83d\udd39\" Advanced GKE Interview Questions<\/h3>\n\n\n\n
          \n
        1. How can you integrate CI\/CD pipelines with GKE?<\/strong>
