SP Cloud and Virtualization Services 2 — Questions and Answers
Question 1: What is the primary benefit of containerization (e.g., Docker) for service providers?
- Reduces need for physical firewalls
- Packages applications with all dependencies so they run consistently across any environment (Correct answer)
- Replaces virtualization entirely
- Provides dedicated hardware to each application
Correct answer: Packages applications with all dependencies so they run consistently across any environment
Containers bundle application code with its runtime dependencies into a portable unit, eliminating the 'works on my machine' problem and enabling consistent deployment across environments.
Question 2: In cloud computing, what is 'object storage' best suited for?
- Database transactions requiring low latency
- Storing large volumes of unstructured data like media files, backups, and logs at scale (Correct answer)
- Running virtual machine disk images
- Real-time block-level storage for operating systems
Correct answer: Storing large volumes of unstructured data like media files, backups, and logs at scale
Object storage is designed for massive scale storage of unstructured data accessed via HTTP APIs, ideal for media, backups, and static web assets.
Question 3: What does 'serverless computing' mean for a service provider customer?
- Running applications on physical servers without virtualization
- Executing code in response to events without managing underlying server infrastructure (Correct answer)
- A bare-metal hosting model with no OS overhead
- Networking without dedicated server hardware
Correct answer: Executing code in response to events without managing underlying server infrastructure
Serverless computing (e.g., AWS Lambda) lets developers deploy functions that execute on-demand in response to events without provisioning, managing, or scaling any servers.
Question 4: What is 'high availability' (HA) architecture in cloud services?
- Maximizing single-server performance with high-end hardware
- Designing systems with redundancy so they continue operating despite individual component failures (Correct answer)
- Providing 24/7 phone support to cloud customers
- Using the highest tier of cloud pricing for performance guarantees
Correct answer: Designing systems with redundancy so they continue operating despite individual component failures
High availability architecture deploys redundant components across multiple zones or regions so that the failure of any single component does not cause service disruption.
Question 5: What is a 'managed Kubernetes service' offered by cloud service providers?
- A managed database service for containerized apps
- A cloud-hosted container orchestration platform where the provider manages the control plane (Correct answer)
- A monitoring service for Docker containers
- A managed firewall for container network traffic
Correct answer: A cloud-hosted container orchestration platform where the provider manages the control plane
Managed Kubernetes services (EKS, AKS, GKE) provide a hosted Kubernetes control plane so customers can deploy containerized workloads without managing cluster infrastructure.
Question 6: In a cloud environment, what is the purpose of a Virtual Private Cloud (VPC)?
- A private physical server within a shared data center
- An isolated, logically defined network section within a public cloud for deploying private resources (Correct answer)
- A VPN connection from on-premises to cloud
- A dedicated cloud account for enterprise customers
Correct answer: An isolated, logically defined network section within a public cloud for deploying private resources
A VPC creates an isolated virtual network environment within a public cloud where customers control IP ranges, subnets, route tables, and network access rules.
