Discover the essentials of AWS EC2 and VPC with these foundational questions covering instance types, scaling, and cloud benefits for beginners. This quiz will help you solidify your understanding of key concepts in cloud computing and virtual networks.
What does EC2 stand for in cloud computing?
Explanation: EC2 stands for Elastic Compute Cloud, which enables resizable compute capacity. 'Elastic Cloud Cluster' and 'External Compute Console' are not AWS service names. 'Edge Computing Center' relates to edge computing, not EC2.
Which feature of EC2 allows you to quickly adjust the number of virtual servers based on demand?
Explanation: Scalability refers to the ability to increase or decrease computing resources quickly. 'Encryption' secures data, 'Auto-repair' is about self-healing, and 'Static hosting' relates to serving static content, not scaling compute resources.
Which EC2 instance type would best fit an application that needs a balance between performance and cost?
Explanation: General Instances are designed for a balance of performance and cost, suitable for moderate workloads. 'Compute Instances' are for CPU-intensive tasks, 'Memory Optimized' for memory-heavy needs, and 'Storage Instances' for high disk throughput.
In EC2, what is the term for a virtual server with its own resources like hard drive, network connection, and OS?
Explanation: An 'Instance' in EC2 is a virtual server with its own isolated resources. 'Protocol' is for communication standards, 'Subnet' is a network segment, and 'Container' is a different virtualization technology.
Which is a primary reason why using EC2 can be more cost-effective compared to managing your own physical servers?
Explanation: With EC2, you pay for actual usage and do not need to maintain physical hardware. The other options are incorrect: EC2 is managed remotely, updates are typically managed by the provider, and multiple billing options are available.
