Exploring Amazon Cloud Services

What is the primary purpose of AWS Global Infrastructure?

• To provide on-premises data storage solutions.

• To enhance local network performance only.

• To provide a reliable, scalable, and secure cloud computing environment globally.

• To limit cloud access to specific regions.

Which AWS service provides virtual servers in the cloud?

• Amazon RDS

• Amazon S3

• Amazon EC2

• AWS Lambda

What are the different types of EC2 instances based on use case?

• Virtual Private Servers

• Web Hosting Instances

• Database Instances

• General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, GPU Instances, High Performance Computing (HPC) Instances

How does Amazon S3 ensure data durability?

• Data is backed up only once a month.

• Amazon S3 ensures data durability by replicating data across multiple locations and performing regular integrity checks.

• Data is encrypted to prevent loss.

• Data is stored on a single server for faster access.

What is the maximum size of a single object that can be stored in S3?

• 10 TB

• 1 TB

• 5 TB

• 100 GB

What is the role of IAM in AWS?

• IAM is used for data storage in AWS.

• IAM manages the physical servers in AWS.

• IAM is responsible for network configuration in AWS.

• IAM in AWS is used for managing user access and permissions to AWS resources.

How can you manage user permissions in AWS?

• Use IAM to create users, groups, and roles, and assign policies for permissions.

• Use CloudFormation to automate user creation.

• Create a VPC to control network permissions.

• Use S3 to store user data and manage access.

What is the difference between IAM roles and IAM users?

• IAM roles are permanent identities with fixed permissions, while IAM users are temporary.

• IAM roles can only be used by users, while IAM users can assume roles.

• IAM roles have no permissions, while IAM users have all permissions.

• IAM roles are temporary and can be assumed by services, while IAM users are permanent identities with fixed permissions.

What is AWS Lambda primarily used for?

• Managing virtual machines in the cloud.

• Storing data in a relational database.

• Providing a graphical user interface for applications.

• Running code in response to events in a serverless manner.

How does serverless computing differ from traditional computing?

• Serverless computing automatically manages resources and scales based on demand, while traditional computing requires manual server management and provisioning.

• Serverless computing requires constant manual intervention for scaling.

• Traditional computing automatically scales resources based on user demand.

• Serverless computing is only suitable for small applications and not for enterprise solutions.
