Amazon EC2 (Elastic Compute Cloud) is a scalable and flexible web service offered by Amazon Web Services (AWS) that provides on-demand computing resources in the cloud. It allows users to rent virtual servers, known as instances, which can be quickly launched, configured, and managed to run applications with varying workloads.
Key features include a wide range of instance types optimized for specific needs—such as compute-intensive tasks, memory-heavy applications, or GPU-accelerated processing—enabling cost-effective scaling based on demand. Users pay only for the compute power they consume, with options for spot instances, reserved capacity, and on-demand pricing.
EC2 integrates seamlessly with other AWS services, offering robust security through features like Virtual Private Clouds (VPCs), encryption, and identity management. This makes it ideal for diverse use cases, including web hosting, data analytics, machine learning, and enterprise applications, empowering businesses to innovate without the overhead of physical hardware.

3. Question: What does AMI stand for in the context of Amazon EC2?
A. Amazon Machine Interface
B. Amazon Management Instance
C. Amazon Machine Image
D. Amazon Managed Infrastructure
Answer: C
Explanation: An AMI is a template that contains the software configuration required to launch an EC2 instance.
4. Question: Which EC2 instance type is optimized for compute-intensive applications?
A. T2
B. C5
C. R5
D. I3
Answer: B
Explanation: C5 instances are designed for compute-intensive workloads, providing high-performance processors with a balance of compute, memory, and networking.
5. Question: How does Amazon EC2 handle instance storage?
A. Only through EBS volumes
B. Only through instance store volumes
C. Both EBS and instance store volumes
D. Through S3 buckets only
Answer: C
Explanation: EC2 instances can use EBS volumes for persistent block storage and instance store volumes for temporary, high-performance storage.
6. Question: What is the purpose of EC2 Auto Scaling?
A. To manually scale instances
B. To automatically adjust the number of instances based on demand
C. To encrypt data on instances
D. To manage network traffic
Answer: B
Explanation: Auto Scaling monitors applications and automatically adds or removes EC2 instances to maintain performance and cost efficiency.
7. Question: Which feature of EC2 helps in distributing incoming traffic across multiple instances?
A. Security Groups
B. Elastic Load Balancing
C. VPC
D. IAM Roles
Answer: B
Explanation: Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as EC2 instances.
8. Question: What is a key benefit of using Reserved Instances in EC2?
A. Lower cost for sporadic usage
B. Discounts for long-term commitments
C. Pay-as-you-go flexibility
D. Unlimited storage
Answer: B
Explanation: Reserved Instances provide significant discounts on hourly charges for instances that are reserved for a one- or three-year term.
9. Question: In Amazon EC2, what do Security Groups act as?
A. Virtual firewalls
B. Load balancers
C. Storage controllers
D. Network routers
Answer: A
Explanation: Security Groups function as virtual firewalls that control inbound and outbound traffic to EC2 instances.
10. Question: Which EC2 purchase option is ideal for short-term, interruptible workloads?
A. On-Demand Instances
B. Reserved Instances
C. Spot Instances
D. Dedicated Hosts
Answer: C
Explanation: Spot Instances are suitable for flexible, interruptible workloads as they use spare EC2 capacity at a lower price, but can be terminated if the spot price changes.
11. Question: What is the default tenancy for an EC2 instance?
A. Dedicated
B. Shared
C. Host
D. Isolated
Answer: B
Explanation: By default, EC2 instances run on shared tenancy, meaning they share the underlying hardware with other instances from any AWS account.
