AWS Concepts Explained
Understand the reasoning behind each answer with detailed AWS service explanations.
Question 1: Amazon VPC (Virtual Private Cloud)
Correct Answer: B) Amazon VPC
Amazon VPC (Virtual Private Cloud) is the foundational networking service that allows you to launch AWS resources in a logically isolated virtual network.
Key Points:
- Provides complete control over your virtual networking environment
- Allows you to define IP address ranges, subnets, route tables, and network gateways
- Enables both internet-facing and private resources within the same VPC
- Essential for security and network segmentation in AWS
Why not others? IAM is for access management, Direct Connect is for dedicated network connections, Route 53 is for DNS services.
Question 2: Amazon S3 Benefits
Correct Answer: C) High durability and availability for object storage
Amazon S3 (Simple Storage Service) is designed for 99.999999999% (11 9's) durability and 99.99% availability.
Key S3 Features:
- Durability: Data is automatically replicated across multiple Availability Zones
- Availability: Designed for high concurrent access with low latency
- Scalability: Virtually unlimited storage capacity
- Security: Built-in encryption and access control mechanisms
S3 is object storage, not suitable for low-latency computing or database operations.
Question 3: AWS Global Infrastructure
Correct Answer: B) Availability Zones, Regions, and Edge Locations
The AWS Global Infrastructure consists of three main components that work together to provide scalable, reliable cloud services.
Breakdown:
- Regions: Geographic areas (like us-east-1, eu-west-1) containing multiple Availability Zones
- Availability Zones (AZs): Isolated locations within Regions, each with redundant power, networking, and connectivity
- Edge Locations: Sites used by CloudFront (CDN) to cache content closer to end-users
This architecture provides fault tolerance, low latency, and global scalability.
Question 4: Serverless Relational Database
Correct Answer: D) Amazon Aurora Serverless
Amazon Aurora Serverless is an auto-scaling configuration for Amazon Aurora that automatically starts up, shuts down, and scales capacity based on your application's needs.
Serverless Benefits:
- No capacity planning required
- Pay-per-use billing (per second)
- Automatic scaling based on workload
- Fully managed - no server maintenance
Why not others? Redshift is for data warehousing, DynamoDB is NoSQL, RDS requires manual scaling.
Question 5: Availability Zone Purpose
Correct Answer: C) To act as a fault-tolerant building block within an AWS Region
Availability Zones are physically separate and isolated locations within each AWS Region that are engineered to be insulated from failures in other Availability Zones.
AZ Characteristics:
- Each AZ has independent power, cooling, and networking
- Connected through low-latency, high-throughput links
- Designed for high availability and fault tolerance
- Applications can be distributed across multiple AZs for resilience
Edge Locations handle content distribution, while Regions provide geographic separation.
Question 6: Compute Services
Correct Answer: A) Amazon EC2
Amazon EC2 (Elastic Compute Cloud) provides scalable computing capacity in the AWS cloud, allowing you to launch virtual servers.
EC2 Features:
- Virtual servers called "instances"
- Multiple instance types optimized for different workloads
- Flexible pricing models (On-Demand, Reserved, Spot)
- Complete control over operating system and applications
Why not others? Lambda is serverless, ECS is container service, Elastic Beanstalk is PaaS platform.
Question 7: Shared Responsibility Model
Correct Answer: D) Security and compliance responsibilities
The AWS shared responsibility model divides security responsibilities between AWS and the customer.
AWS Responsibility (Security OF the Cloud):
- Infrastructure security (hardware, software, networking)
- Managed services security
- Global infrastructure security
Customer Responsibility (Security IN the Cloud):
- Data encryption and integrity
- IAM user access management
- Operating system and application security
Question 8: Serverless Computing
Correct Answer: B) AWS Lambda
AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume.
Lambda Benefits:
- No server management - AWS handles capacity provisioning
- Automatic scaling - scales with incoming requests
- Subsecond billing - pay per 100ms of execution time
- Event-driven - responds to events from other AWS services
Why not others? EC2 requires server management, Fargate is for containers, Lightsail is simplified VPS.
Question 9: Content Delivery Network
Correct Answer: C) To deliver content with low latency via a CDN
Amazon CloudFront is a fast Content Delivery Network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally.
CloudFront Features:
- Global network of Edge Locations
- Low latency content delivery
- DDoS protection with AWS Shield
- Integration with other AWS services
CloudFront caches content at Edge Locations close to users, reducing latency for frequently accessed content.
Question 10: NoSQL Database
Correct Answer: A) Amazon DynamoDB
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.
DynamoDB Features:
- Serverless - no servers to manage
- Automatic scaling based on traffic
- Single-digit millisecond latency
- Built-in security, backup, and restore
Why not others? RDS is relational, Redshift is data warehouse, ElastiCache is in-memory cache.
