Tanzu Interview Questions and Answers for internship

1. What is VMware Tanzu?

   • Answer: VMware Tanzu is a portfolio of products and services that helps organizations build, run, and manage modern applications on Kubernetes. It encompasses a range of offerings, from Kubernetes distributions (Tanzu Kubernetes Grid) to application management platforms (Tanzu Application Platform) and developer tools. Essentially, it aims to simplify and streamline the process of deploying and operating cloud-native applications.

2. What is Kubernetes?

   • Answer: Kubernetes is an open-source container orchestration platform. It automates the deployment, scaling, and management of containerized applications. Think of it as a sophisticated system that manages and coordinates containers across a cluster of machines, ensuring high availability and efficient resource utilization.

3. Explain the difference between containers and virtual machines.

   • Answer: Containers share the host operating system's kernel, making them lightweight and efficient. VMs, on the other hand, have their own complete operating system, leading to higher resource consumption. Containers are faster to start and stop and require less overhead. VMs offer greater isolation but at the cost of performance and resource usage.

4. What are some benefits of using Kubernetes?

   • Answer: Kubernetes offers several benefits, including automated deployment and scaling, self-healing capabilities (replacing failing containers), efficient resource utilization, declarative configuration, and improved portability across different cloud environments.

5. What is a pod in Kubernetes?

   • Answer: A pod is the smallest deployable unit in Kubernetes. It represents a running process, typically containing one or more containers, along with shared storage and network resources. Pods are ephemeral; if a node fails, Kubernetes automatically restarts them on another node.

6. What are deployments in Kubernetes?

   • Answer: Deployments manage the desired state of a set of pods. They handle rolling updates, rollbacks, and scaling of applications. They ensure that the specified number of pods are always running, even if some fail.

7. What are services in Kubernetes?

   • Answer: Services provide a stable IP address and DNS name for a set of pods. They abstract away the underlying pod IPs, allowing applications to communicate with each other regardless of pod changes or failures.

8. Explain the concept of namespaces in Kubernetes.

   • Answer: Namespaces provide logical separation within a Kubernetes cluster. They allow you to organize resources like pods, deployments, and services into distinct groups, preventing naming conflicts and improving resource management.

9. What is a Kubernetes ingress?

   • Answer: An ingress acts as a reverse proxy and load balancer for HTTP traffic entering the cluster. It exposes services externally, often managing TLS/SSL termination and routing requests based on rules defined in its configuration.

10. What are ConfigMaps and Secrets in Kubernetes?

    • Answer: ConfigMaps store configuration data as key-value pairs, allowing you to separate configuration from application code. Secrets store sensitive information like passwords and API keys securely, preventing them from being hardcoded into application code.

11. What is a Helm chart?

    • Answer: A Helm chart is a package manager for Kubernetes. It simplifies the process of deploying and managing complex applications by packaging related Kubernetes resources into a single unit. It allows for versioning and easy updates.

12. What are some common Kubernetes monitoring tools?

    • Answer: Prometheus, Grafana, and Datadog are popular choices for monitoring Kubernetes clusters and applications. They provide insights into resource utilization, application performance, and overall cluster health.

13. What experience do you have with cloud platforms like AWS, Azure, or GCP?

    • Answer: [Replace with your actual experience. Be specific about services used and tasks performed. Example: "I have experience with AWS, specifically using EC2 for instance management and S3 for object storage. I've also worked with AWS Lambda for serverless functions."]

14. What is your experience with CI/CD pipelines?

    • Answer: [Replace with your actual experience. Example: "I have used Jenkins to build and deploy applications. I am familiar with the concept of automated testing and continuous integration."]

15. Describe your experience with Git and version control.

    • Answer: [Replace with your actual experience. Example: "I'm proficient in Git, using it daily for collaboration on projects. I'm familiar with branching strategies like Gitflow and understand the importance of commit messages."]
