Syllabus & Core Topics

core cloud architectureAWS storage and computeshared security protocolscloud cost modelingAWS support guidelines

Earning your certification requires bridging the gap between passive reading and active identification. Frequently contrasting common elements like EC2, S3, and IAM across different scenarios cements your knowledge and builds a natural instinct for how AWS measures and charges for cloud usage.

Why this practice page is useful

Many students recognize cloud computing in theory but mix up similar resources like EBS, EFS, and S3 once the timer starts — this test builds the speed needed to map services to workloads instantly.
Memorizing pricing model names is easy; knowing whether a given architecture calls for Spot pricing, Savings Plans, or Reserved Instances is what actually decides your score.
The shared responsibility model is tested from several confusing angles — these practical scenarios pin down exactly where Amazon's security ends and yours begins.

Answer key & quick explanations

Short answers for the sample questions above. Use this to self-check before generating a fresh AI-built mock test.

1. What is the AWS Shared Responsibility Model?
C) AWS manages security OF the cloud; customers manage security IN the cloud
AWS secures the infrastructure underneath its services — hardware, data centers, the physical network — while the customer secures what they put on top of it, such as data, IAM configuration, and application settings. It isn't an even split; the exact line depends on the service.
2. Which AWS service provides object storage?
B) Amazon S3
Amazon S3 stores data as objects (files) rather than blocks or a file system, which is why it's used for backups, static assets, and media. EBS and EFS are block/file storage for EC2, and RDS is a relational database service, not storage for arbitrary files.
3. What is the benefit of AWS Regions?
B) Deploying closer to users to reduce latency
Running resources in a Region near your users shortens the network distance data has to travel, which lowers latency. Regions also support data-residency and compliance needs, but the benefit this question is testing is latency.
4. Which pricing model is best for unpredictable workloads?
C) On-Demand
On-Demand has no upfront commitment, so it's the safest choice when you can't predict how much compute you'll need. Reserved Instances and Savings Plans require a 1- or 3-year commitment, and Spot Instances can be reclaimed by AWS with little warning.
5. What does the AWS Free Tier offer?
B) Limited free usage of certain services for 12 months
The Free Tier gives capped free usage of specific services — like 750 hours a month of a t2.micro EC2 instance — for the first 12 months, plus a small set of always-free services. It isn't unlimited or permanent access to everything AWS offers.
6. Which service is used to run virtual servers in AWS?
B) Amazon EC2
Amazon EC2 (Elastic Compute Cloud) provisions resizable virtual machines. Lambda is serverless compute with no managed instance, S3 is object storage, and VPC is networking, not compute.
7. What is Amazon CloudFront?
B) A CDN that delivers content to users with low latency
CloudFront is AWS's content delivery network — it caches content at edge locations around the world so users get faster access to both static and dynamic content.
8. What does IAM stand for?
B) Identity and Access Management
IAM is the AWS service that controls identity (who you are) and access (what you're allowed to do), through users, groups, roles, and policies.
9. Which support plan provides 24/7 access to Cloud Support Engineers?
C) Business
The Business plan (and the tiers above it) includes 24/7 phone, chat, and email access to Cloud Support Engineers. Developer support is business-hours email only, and Basic/Free include no technical support.
10. What is a key benefit of cloud computing over traditional on-premises infrastructure?
C) Trade capital expense for operational expense
Instead of buying and depreciating hardware upfront (capital expense), the cloud lets you pay for what you actually use as you use it (operational expense) — one of AWS's core cost arguments.
11. Which AWS service provides a managed relational database?
B) Amazon RDS
Amazon RDS manages relational engines like MySQL, PostgreSQL, and SQL Server, handling patching, backups, and scaling for you. DynamoDB is NoSQL, S3 is object storage, and Redshift is a data warehouse rather than a general-purpose relational database.
12. What is the purpose of AWS Availability Zones?
B) Provide high availability and fault tolerance within a Region
Availability Zones are physically separate data centers within a Region, linked by low-latency connections. Spreading resources across more than one AZ protects you if a single data center has a problem.
13. Which service helps you estimate AWS costs before deploying?
B) AWS Pricing Calculator
The AWS Pricing Calculator lets you model the cost of a proposed architecture before you build it. Cost Explorer and Budgets analyse spending you've already incurred, and Trusted Advisor gives broader best-practice checks rather than cost estimates.
14. What is Amazon VPC?
A) A virtual private cloud — an isolated network within AWS
A VPC is a logically isolated section of AWS where you define your own IP address range, subnets, and routing — effectively your own private network inside the AWS cloud.
15. Which AWS service allows you to run code without managing servers?
C) AWS Lambda
Lambda runs your code in response to events without you provisioning or managing any servers. EC2 and Lightsail still require you to manage instances, and ECS needs you to manage underlying compute unless it's paired with Fargate.
16. What does "elasticity" mean in cloud computing?
B) The ability to scale resources up or down automatically based on demand
Elasticity means capacity automatically grows or shrinks to match real-time demand, so you're not stuck permanently over-provisioned or under-provisioned.
17. Which AWS service provides DNS (Domain Name System)?
C) Amazon Route 53
Route 53 is AWS's DNS and domain registration service, and it also supports health checks and several traffic-routing policies.
18. What is the difference between horizontal and vertical scaling?
A) Horizontal = adding more instances; vertical = adding more power to existing instances
Horizontal scaling (scaling out) adds more instances to share the load; vertical scaling (scaling up) increases the CPU, memory, or other resources on an existing instance.
19. Which security service helps protect against DDoS attacks?
B) AWS Shield
AWS Shield is purpose-built to protect against Distributed Denial of Service attacks. WAF filters malicious web requests, GuardDuty detects broader threats from logs, and IAM manages access rather than attack traffic.
20. What is an AWS S3 bucket?
B) A container for storing objects (files) in Amazon S3
A bucket is the top-level container that holds the objects you store in S3, similar in concept to a globally-named folder.
21. Which AWS service provides monitoring and observability?
B) Amazon CloudWatch
CloudWatch collects metrics, logs, and alarms for monitoring resource performance and health. CloudTrail logs API activity for auditing and Config tracks configuration changes — related jobs, but not the same one.
22. What is the purpose of AWS CloudTrail?
B) To log API calls and user activity for auditing
CloudTrail records who did what, when, and from where by logging API calls across your account, which makes it central to security auditing and incident investigation.
23. Which instance purchasing option provides the biggest discount for steady-state workloads?
C) Reserved Instances (1 or 3 year)
Reserved Instances give the largest discount when you already know a workload will run continuously for one or three years. Spot can be cheaper but is interruptible, and On-Demand carries no discount at all.
24. What does "high availability" mean in AWS architecture?
B) The system is designed to remain operational even during failures
High availability describes an architecture — often spanning multiple Availability Zones — built to keep running through individual component failures. It's not a claim about speed, cost, or location.
25. Which AWS service is used for sending emails?
B) Amazon SES
Amazon SES (Simple Email Service) is built specifically for sending and receiving email at scale. SNS handles pub/sub notifications and SQS is a message queue — neither is an email-sending service.
26. What is the AWS Well-Architected Framework?
B) A set of best practices for building secure, efficient, resilient cloud systems
The Well-Architected Framework is a collection of best practices, organised into pillars such as Security, Reliability, Performance Efficiency, Cost Optimisation, and Operational Excellence, for designing and running cloud workloads well.
27. Which pillar of the AWS Well-Architected Framework focuses on preventing financial overruns?
C) Cost Optimisation
The Cost Optimisation pillar is specifically about avoiding unnecessary spend and getting the best return on cloud investment — the pillar most directly tied to keeping budgets in check.
28. What is Amazon EBS?
A) Elastic Block Store — persistent block storage for EC2 instances
EBS provides persistent block-storage volumes that attach to EC2 instances, behaving much like a virtual hard drive that survives an instance being stopped and started again.
29. Which service provides automatic distribution of incoming traffic across multiple targets?
B) Elastic Load Balancing
Elastic Load Balancing automatically spreads incoming application traffic across multiple targets — EC2 instances, containers, or IP addresses — in one or more Availability Zones.
30. What is the purpose of AWS Trusted Advisor?
B) To offer real-time guidance to help provision resources following AWS best practices
Trusted Advisor inspects your account and surfaces recommendations across cost optimisation, performance, security, fault tolerance, and service limits, based on AWS best practices.
