IBM Cloud Interview Questions & Answers

  1. What is IBM Cloud?

    • Answer: IBM Cloud is a suite of cloud computing services offered by IBM, providing infrastructure, platform, and software as a service (IaaS, PaaS, SaaS) offerings. It encompasses various services like compute, storage, networking, databases, AI, security, and IoT solutions, allowing businesses to build, deploy, and manage applications and workloads in the cloud.

  2. Explain the difference between IaaS, PaaS, and SaaS.

    • Answer: IaaS (Infrastructure as a Service) provides virtualized computing resources like servers, storage, and networking. PaaS (Platform as a Service) offers a platform for developing, running, and managing applications without managing the underlying infrastructure. SaaS (Software as a Service) delivers software applications over the internet, eliminating the need for installation and maintenance on the client's side. IBM Cloud offers all three.

  3. What are some key services offered by IBM Cloud?

    • Answer: Key services include IBM Cloud Virtual Servers (compute), Cloud Object Storage, Cloud Databases (various types like Db2, PostgreSQL, MongoDB), Kubernetes Service, Watson AI services (e.g., Natural Language Processing, Machine Learning), Blockchain services, and security services like Identity and Access Management (IAM).

  4. Describe your experience with IBM Cloud Virtual Servers.

    • Answer: [This answer should be tailored to the candidate's experience. Example: "I have extensive experience provisioning and managing virtual servers on IBM Cloud, using various operating systems like Linux and Windows. I've worked with different instance sizes to optimize performance and cost, and I'm familiar with configuring networks, security groups, and storage volumes."]

  5. How have you used IBM Cloud Object Storage?

    • Answer: [Tailored answer. Example: "I've used IBM Cloud Object Storage for archiving large datasets, backups, and storing media assets. I'm familiar with managing buckets, setting access control lists (ACLs), and utilizing lifecycle policies for cost optimization and data retention."]

  6. Explain your experience with IBM Cloud Kubernetes Service (IKS).

    • Answer: [Tailored answer. Example: "I have experience deploying and managing containerized applications on IKS. I'm familiar with concepts like pods, deployments, services, and ingress controllers. I've used kubectl for managing clusters and have experience with CI/CD pipelines integrated with IKS."]

  7. How do you manage costs in IBM Cloud?

    • Answer: I utilize cost management tools provided by IBM Cloud to monitor spending, set budgets, and receive alerts. I also employ techniques like right-sizing instances, utilizing reserved instances, and optimizing storage usage to minimize expenses.

  8. What are your experiences with IBM Cloud security features?

    • Answer: [Tailored answer. Example: "I've worked with IAM to manage user access, implemented security groups to control network traffic, and utilized key management services to protect sensitive data. I understand the importance of regular security patching and vulnerability scanning."]

  9. Describe your experience with IBM Cloud Databases. Which ones have you used?

    • Answer: [Tailored answer, listing specific databases like Db2, PostgreSQL, Cloudant, etc., and describing the tasks performed with each.]

  10. How would you troubleshoot a network connectivity issue in IBM Cloud?

    • Answer: I would start by checking the instance's network interfaces, security groups to ensure that the necessary ports are open, and review the network configuration. I'd also use tools like `ping`, `traceroute`, and the IBM Cloud console to diagnose connectivity problems.
