  1. Which cloud deployment model keeps infrastructure entirely within an organization's own data center or private network?

    Answer: Private cloud

    A private cloud is dedicated solely to one organization, hosted either on-premises or by a third party, offering maximum control and isolation.

  2. In Kubernetes, what resource acts as a stable network endpoint that load-balances traffic to a dynamic set of pods?

    Answer: Service

    A Kubernetes Service provides a stable virtual IP and DNS name that proxies traffic to matching pods, abstracting away individual pod IPs.

  3. What is the main purpose of tagging cloud resources (e.g., EC2 instances, S3 buckets)?

    Answer: To organize, track costs, and apply policies across resources

    Tags are key-value metadata attached to resources, enabling cost allocation reporting, automation, and policy enforcement.

  4. A cloud application experiences intermittent 503 errors when traffic spikes suddenly. Which architectural change BEST addresses this?

    Answer: Add autoscaling policies tied to CPU or request metrics

    Autoscaling automatically adds capacity during traffic spikes, preventing resource exhaustion and 503 Service Unavailable errors.

  5. Which cloud storage concept describes the ability to store an unlimited number of objects with each object accessible via a unique URL/key?

    Answer: Object storage

    Object storage (e.g., S3, GCS) stores data as objects with unique keys, scales to virtually unlimited capacity, and is accessed via HTTP APIs.

  6. What does 'multi-tenancy' mean in the context of public cloud infrastructure?

    Answer: Multiple customers sharing the same underlying physical hardware with logical isolation

    Multi-tenancy means multiple customers' workloads run on shared physical hardware, with the hypervisor and cloud platform providing logical isolation between them.

  7. Which protocol is most commonly used to securely administer Linux cloud instances remotely?

    Answer: SSH

    SSH (Secure Shell) provides encrypted remote terminal access to Linux servers and is the standard for administering cloud VMs.
