A company plans to launch an ecommerce website that contains many images for a product catalog. The company wants to keep the cost of running the website within a specific budget.
Which AWS service or tool should the company use to monitor the ongoing costs of the website?
Answer : A
AWS Cost Exploreris a tool that enables you to view and analyze your costs and usage. It provides an easy-to-use interface to visualize, understand, and manage AWS costs and usage over time. Cost Explorer allows the company to monitor ongoing costs, set budget alerts, and analyze cost drivers, which is ideal for keeping the cost of running an ecommerce website within a specific budget.
B . AWS SDKs: Incorrect, as they are software development kits that allow integration with AWS services but do not provide cost monitoring or management capabilities.
C . EC2 Image Builder: Incorrect, as it is a service for automating the creation of virtual machine images, not for monitoring costs.
D . AWS CloudFormation: Incorrect, as it is used for provisioning and managing infrastructure as code, not for cost monitoring.

Which AWS service or tool provides users with the ability to monitor AWS service quotas?
Answer : C
The correct answer is C because AWS Trusted Advisor is an AWS service or tool that provides users with the ability to monitor AWS service quotas. AWS Trusted Advisor is an online tool that provides users with real-time guidance to help them provision their resources following AWS best practices. One of the categories of checks that AWS Trusted Advisor performs is service limits, which monitors the usage of each AWS service and alerts users when they are close to reaching the default limit. The other options are incorrect because they are not AWS services or tools that provide users with the ability to monitor AWS service quotas. AWS CloudTrail is a service that enables users to track user activity and API usage across their AWS account. AWS Cost and Usage Reports is a tool that enables users to access comprehensive information about their AWS costs and usage. AWS Budgets is a tool that enables users to plan their service usage, costs, and reservations. Reference: [AWS Trusted Advisor FAQs]
Which benefits does a company gain when the company moves from on-premises IT architecture to the AWS Cloud? (Select TWO.)
Answer : A, E
When a company moves from on-premises IT architecture to the AWS Cloud, it gains several benefits:
A . Reduced or eliminated tasks for hardware troubleshooting, capacity planning, and procurement: In an on-premises environment, companies must maintain their own hardware, which involves procuring servers, configuring them, managing capacity, and troubleshooting hardware failures. Moving to the AWS Cloud eliminates or greatly reduces these tasks since AWS is responsible for the underlying infrastructure.
E . Faster deployment of new features and applications: AWS provides scalable resources and automation tools that allow companies to deploy applications faster. Services like AWS Elastic Beanstalk, AWS CloudFormation, and AWS Lambda help streamline the deployment process, enabling quicker time-to-market for new features and applications.
Why other options are not suitable:
B . Elimination of the need for trained IT staff: While the cloud reduces certain operational burdens, it does not eliminate the need for skilled IT professionals to manage cloud services, ensure proper configurations, handle security, and manage applications.
C . Automatic security configuration of all applications that are migrated to the cloud: AWS provides security tools and services, but security configurations and management still require input from the customer to tailor them to specific application requirements.
D . Elimination of the need for disaster recovery planning: While AWS offers robust disaster recovery options, companies must still plan and implement disaster recovery strategies, such as backups and multi-region deployments.

Which AWS service or resource can a company use to deploy AWS WAF rules?
Answer : B
Application Load Balancer (ALB) integrates with AWS WAF to deploy and manage WAF rules for incoming traffic. ALB can route HTTP and HTTPS traffic and apply WAF rules to protect applications from common web exploits. Network Load Balancer does not support AWS WAF, and Trusted Advisor does not deploy WAF rules.
Which AWS service or feature can be used to control inbound and outbound traffic on an Amazon EC2 instance?
Answer : D
D is correct because security groups are the AWS service or feature that can be used to control inbound and outbound traffic on an Amazon EC2 instance. Security groups act as a virtual firewall for the EC2 instance, allowing users to specify which protocols, ports, and source or destination IP addresses are allowed or denied. A is incorrect because internet gateways are the AWS service or feature that enable communication between instances in a VPC and the internet. They do not control the traffic on an EC2 instance. B is incorrect because AWS Identity and Access Management (IAM) is the AWS service or feature that enables users to manage access to AWS services and resources securely. It does not control the traffic on an EC2 instance. C is incorrect because network ACLs are the AWS service or feature that provide an optional layer of security for the VPC that acts as a firewall for controlling traffic in and out of one or more subnets. They do not control the traffic on an EC2 instance.
A company is building an application that will receive millions of database queries each second. The company needs the data store for the application to scale to meet these needs.
Which AWS service will meet this requirement?
Answer : A
Amazon DynamoDB is the AWS service that will meet the requirement of building an application that will receive millions of database queries each second. Amazon DynamoDB is a fully managed NoSQL database service that provides fast and consistent performance, scalability, and durability. Amazon DynamoDB can handle any level of request traffic and automatically scale up or down the capacity based on the demand. Amazon DynamoDB also supports in-memory caching with Amazon DynamoDB Accelerator (DAX) to improve the response time and reduce the cost.

Where can users find examples of AWS Cloud solution designs?
Answer : C
The AWS Architecture Center provides examples, best practices, and architectural blueprints for various AWS Cloud solutions. It includes whitepapers, reference architectures, and detailed diagrams to help users design secure, scalable, and reliable applications on AWS. Other services like AWS Marketplace, Service Catalog, and Trusted Advisor do not offer solution design examples.
