Q: What is IaC?
A: Infrastructure as Code — managing infrastructure through machine-readable files (Terraform, CloudFormation). Enables versioning, repeatability, automation.
Q: What is the shared responsibility model?
A: Cloud provider secures the infrastructure (of the cloud). Customer secures their data, applications, and configurations (in the cloud).
Q: What is auto-scaling?
A: Automatically adjusting compute resources (instances) based on demand. Scale out (add) / Scale in (remove).
Q: What is a VPC?
A: Virtual Private Cloud — logically isolated network in the cloud with custom IP ranges, subnets, route tables, and security groups.
Q: What is Kubernetes?
A: Container orchestration platform: automates deployment, scaling, and management of containerized applications. Core unit: Pod.
Q: What is object storage?
A: Flat storage (no hierarchy) using key-value pairs. Highly scalable, durable. Examples: S3, Azure Blob, GCS.
Q: What is a load balancer?
A: Distributes incoming traffic across multiple servers for availability and performance. Types: L4 (transport) and L7 (application).
Q: What is lift-and-shift migration?
A: Moving an application to cloud with minimal changes. Quick but may not leverage cloud-native benefits.
Q: What is a security group?
A: Cloud firewall rules controlling inbound/outbound traffic to resources. Stateful (AWS) — return traffic auto-allowed.
Q: What is multi-tenancy?
A: Multiple customers sharing same physical infrastructure with logical isolation. Cost-effective but requires strong isolation controls.
CompTIA Flashcard Study Technique
CompTIA exams cover broad domains with hundreds of concepts. Use these flashcards in short, focused sessions of 15–20 minutes rather than marathon study sessions. Group cards by domain and track which domains have the lowest recall rates — allocate extra study time to those areas. CompTIA exams weight domains differently, so match your flashcard focus to the domain percentages listed in the exam objectives.
