TheAWS Pricing Calculatoris a web-based tool that allows customers to estimate their monthly AWS costs by configuring and projecting the costs of different AWS services. The calculator is specifically designed to help customers plan their AWS spending based on their specific architecture and usage patterns. The other options are not correct because:

B. Calculate historical AWS costs: This is incorrect as the AWS Pricing Calculator does not track or calculate historical costs. For historical costs, AWS Cost Explorer is used.

C. Provide in-depth information about AWS pricing strategies: While the AWS Pricing Calculator provides cost estimations, it does not provide detailed insights into AWS pricing strategies.

D. Provide users with access to their monthly bills: This is incorrect; AWS Billing and Cost Management provides access to actual billing information.

According to the AWS shared responsibility model, AWS is responsible for the security of the cloud, while customers are responsible for the security in the cloud. This means that AWS is responsible for the physical servers, networking, and operating system that run DynamoDB, while customers are responsible for the security of their data and access to the database. Customers need to manage database access permissions, such as creating and managing AWS Identity and Access Management (IAM) policies and roles, and using encryption and key management options to protect their data123. References: 1: Shared Responsibility Model - Amazon Web Services (AWS), 2: Security in Amazon DynamoDB - Amazon DynamoDB, 3: AWS Shared Responsibility Model - Introduction to DevOps …

AWS Direct Connect is a service that establishes a dedicated network connection between your on-premises network and one or more AWS Regions. AWS Direct Connect can be used to create a private connection between an on-premises workload and an AWS Cloud workload, bypassing the public internet and reducing network costs, latency, and bandwidth issues. AWS Direct Connect can also provide increased security and reliability for your hybrid cloud applications and data transfers. References:

Consolidated billing is a feature of AWS Organizations that enables customers to consolidate billing and payment for multiple AWS accounts. With consolidated billing, customers can group multiple AWS accounts under one payer account, making it easier to manage billing and track costs across multiple accounts. Consolidated billing also offers benefits such as volume discounts, Reserved Instance discounts, and Savings Plans discounts. Consolidated billing is offered at no additional cost.

Multiple AWS accounts is a feature of AWS Organizations that enables customers to create and manage multiple AWS accounts from a central location. With multiple AWS accounts, customers can isolate workloads for different departments, projects, or environments, and apply granular access controls and policies to each account. Multiple AWS accounts also helps customers improve security, compliance, and governance of their AWS resources56. References: 5: Consolidated billing for AWS Organizations - AWS Billing, 6: Understanding Consolidated Bills - AWS Billing, 7: AWS Consolidated Billing: Tutorial & Best Practices, 8: Simplifying Your Bills With Consolidated Billing on AWS - Aimably, 9: AWS Consolidated Billing - W3Schools

AWS Trusted Advisor is the service that can meet these requirements. AWS Trusted Advisor is a service that helps you optimize your AWS environment by providing recommendations based on AWS best practices. Trusted Advisor continuously evaluates your AWS resources and services across five categories: cost optimization, performance, service limits, fault tolerance, and security. You can view the recommendations on the Trusted Advisor console or access them programmatically using the Trusted Advisor API. You can also set up notifications and alerts for any changes in the status of your checks. Trusted Advisor can help you improve your AWS environment by reducing costs, enhancing performance, increasing security, and ensuring reliability12. The other services are not designed to provide best practice recommendations in five categories. AWS Shield is a service that protects your AWS resources from distributed denial-of-service (DDoS) attacks. AWS WAF is a service that helps you protect your web applications from common web exploits. AWS Service Catalog is a service that enables you to create and manage catalogs of IT services that are approved for use on AWS34 . References: AWS Trusted Advisor, Achieve operational excellence with AWS Trusted Advisor, AWS Shield, AWS WAF, [AWS Service Catalog]

According to the AWS shared responsibility model, AWS is responsible for security of the cloud, while customers are responsible for security in the cloud. This means that AWS is responsible for protecting the infrastructure that runs AWS services, such as hardware, software, networking, and facilities. Customers are responsible for managing their data, classifying their assets, and using IAM tools to apply the appropriate permissions. For abstracted services, such as Amazon DynamoDB, AWS operates the infrastructure layer, the operating system, and platforms, and provides customers with public endpoints to store and retrieve data. Customers are responsible for classifying their data, managing their encryption options, and configuring their access permissions. References: Shared Responsibility Model, Security and compliance in Amazon DynamoDB, [AWS Cloud Practitioner Essentials: Module 2 - Security in the Cloud]
