Understanding AWS Concepts

What is an AWS region?

• An AWS region is a single data center located in one city.

• An AWS region is a geographical area containing multiple isolated data centers.

• An AWS region is a virtual network for cloud computing.

• An AWS region is a type of database service offered by AWS.

How many availability zones are typically in a region?

• 1 to 2

• 12 to 15

• 7 to 10

• 3 to 6

What is the purpose of edge locations in AWS?

• To deliver content with low latency by caching it closer to end users.

• To store data in a centralized database.

• To manage user authentication and access control.

• To provide backup and disaster recovery services.

How does CloudFront improve content delivery?

• CloudFront speeds up content delivery by using a single data center.

• CloudFront improves content delivery by increasing server load times.

• CloudFront improves content delivery by caching content at edge locations, reducing latency and optimizing delivery.

• CloudFront enhances content delivery by storing data in a central location.

What is the shared responsibility model in AWS?

• Customers have no security responsibilities in AWS.

• In AWS, the shared responsibility model defines the division of security responsibilities between AWS and the customer.

• AWS is solely responsible for all security measures.

• The model only applies to data storage services.

What are IAM roles used for in AWS?

• IAM roles are used to permanently store user credentials.

• IAM roles are used to grant temporary access to AWS resources without sharing long-term credentials.

• IAM roles are used to create new AWS accounts.

• IAM roles are used to monitor network traffic in AWS.

Can you name a benefit of using multiple availability zones?

• Simplified network architecture.

• Increased fault tolerance.

• Reduced operational costs.

• Lower latency for data access.

What is the difference between an AWS region and an availability zone?

• An AWS region is a single data center, while an availability zone is a collection of regions.

• An AWS region is a virtual network, while an availability zone is a physical server.

• An AWS region is a collection of availability zones, while an availability zone is a single data center within that region.

• An AWS region is a backup service, while an availability zone is a storage solution.

How does AWS ensure high availability across regions?

• AWS uses manual intervention for all failover processes.

• AWS relies solely on a single data center for availability.

• AWS does not support cross-region data replication.

• AWS uses multiple Availability Zones, load balancing, automated failover, and cross-region replication to ensure high availability.

What is the primary function of AWS Identity and Access Management (IAM)?

• To provide data storage solutions in AWS.

• To monitor AWS service performance and health.

• To automate the deployment of AWS resources.

• The primary function of AWS Identity and Access Management (IAM) is to manage access to AWS services and resources.
