CCP AWS Core Compute and Storage Services 2 — Questions and Answers
Question 1: Which EC2 instance type is optimized for applications that require high compute performance, such as scientific modeling?
- Memory-optimized (R-series)
- Compute-optimized (C-series) (Correct answer)
- Storage-optimized (I-series)
- General-purpose (T-series)
Correct answer: Compute-optimized (C-series)
Compute-optimized (C-series) instances are ideal for CPU-intensive workloads like batch processing, scientific modeling, and high-performance web servers.
Question 2: What is Auto Scaling in AWS?
- Automatically upgrading EC2 instance sizes
- Automatically adding or removing EC2 instances based on demand to maintain performance and control costs (Correct answer)
- Automatically replicating data across Regions
- Automatically patching EC2 operating systems
Correct answer: Automatically adding or removing EC2 instances based on demand to maintain performance and control costs
AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost.
Question 3: Which AWS service distributes incoming application traffic across multiple EC2 instances to improve availability?
- Amazon Route 53
- Amazon CloudFront
- Elastic Load Balancing (ELB) (Correct answer)
- AWS Global Accelerator
Correct answer: Elastic Load Balancing (ELB)
Elastic Load Balancing automatically distributes incoming traffic across multiple targets (EC2 instances, containers, or IPs) in one or more AZs.
Question 4: What is Amazon S3 Glacier used for?
- Hosting static websites
- Long-term archival storage at very low cost with infrequent access requirements (Correct answer)
- Real-time data processing
- Caching frequently accessed data
Correct answer: Long-term archival storage at very low cost with infrequent access requirements
Amazon S3 Glacier is a low-cost storage class designed for data archiving with retrieval times ranging from minutes to hours.
Question 5: Which AWS service provides a managed container orchestration platform based on Kubernetes?
- Amazon ECS
- AWS Fargate
- Amazon EKS (Correct answer)
- AWS Batch
Correct answer: Amazon EKS
Amazon EKS (Elastic Kubernetes Service) is a fully managed Kubernetes service that makes it easy to run Kubernetes on AWS without installing and operating your own Kubernetes clusters.
Question 6: What is AWS Fargate?
- A dedicated hardware service for containers
- A serverless compute engine for containers that removes the need to manage servers or EC2 instances (Correct answer)
- A container registry for storing Docker images
- A monitoring service for containerized applications
Correct answer: A serverless compute engine for containers that removes the need to manage servers or EC2 instances
AWS Fargate is a serverless compute engine for Amazon ECS and EKS that lets you run containers without managing the underlying EC2 servers.
