A Network Access Control List (ACL) is a stateless network filtering mechanism provided by AWS for controlling traffic in and out of subnets within a VPC. Unlike security groups, which are stateful, network ACLs are stateless. This means that they do not automatically allow responses to inbound traffic unlessexplicitly specified. Network ACLs allow you to set rules for both inbound and outbound traffic, making them suitable for stateless filtering. Security groups, on the other hand, are stateful, while AWS WAF is primarily for web application-level security. AWS PrivateLink is used for privately connecting VPCs to AWS services without using an internet gateway. Therefore, for stateless network filtering, Network ACL is the correct choice.

VPC Flow Logs is a feature that enables you to capture information about the IP traffic going to and from network interfaces in your VPC. Flow log data can be published to Amazon CloudWatch Logs, Amazon S3, or Amazon Kinesis Data Firehose. You can use VPC Flow Logs to diagnose network issues, monitor traffic patterns, detect security anomalies, and comply with auditing requirements34. References: Logging IP traffic using VPC Flow Logs - Amazon Virtual Private Cloud, New – VPC Traffic Mirroring – Capture & Inspect Network Traffic | AWS News Blog

AWS Key Management Service (AWS KMS) is designed to integrate with various AWS services to encrypt data at rest. It provides a secure and highly available service to create, control, and manage encryption keys used to encrypt your data. AWS Certificate Manager (ACM) is for managing SSL/TLS certificates, AWS Identity and Access Management (IAM) is for managing user access and permissions, and AWS Security Hub is for security monitoring and compliance, but none of these services provide data encryption at rest like AWS KMS.QUESTION NO: 298

A company has an AWS Business Support plan. The company needs to gain access to the AWS DDoS Response Team (DRT) to help mitigate DDoS events.

Which AWS service or resource must the company use to meet these requirements?

A. AWS Shield Standard

B. AWS Enterprise Support

C. AWS WAF

D. AWS Shield Advanced

Answer: D

AWS Shield Advanced provides enhanced protection against DDoS attacks and includes access to the AWS DDoS Response Team (DRT) to help mitigate complex DDoS events. AWS Shield Standard offers basic DDoS protection, which is included with AWS services, but does not provide access to the DRT. AWS WAF is a web application firewall, and AWS Enterprise Support is a premium support plan but does not specifically provide DDoS mitigation services or access to the DRT.

AWS Identity and Access Management (IAM) is a service that helps you securely control access to AWS resources for your users. You use IAM to control who can use your AWS resources (authentication) and what resources they can use and in what ways (authorization). IAM also enables you to follow the principle of least privilege, which means granting only the permissions that are necessary to perform a task1. References: AWS Identity and Access Management (IAM) - AWS Documentation

AWS Trusted Advisor is a tool that helps customers optimize their AWS environment by providing real-time guidance in five key areas: cost optimization, performance, security, fault tolerance, and service limits. However, the availability of the full set of Trusted Advisor checks depends on the AWS Support plan chosen.

AWS Developer Support: This plan provides access to only seven core Trusted Advisor checks. It is designed for developers experimenting or testing in AWS and does not offer the full set of Trusted Advisor checks.

AWS Business Support: This plan is the lowest-cost support plan that provides access to thefull set of AWS Trusted Advisor checks. Business Support is intended for production workloads, providing a broader range of checks, 24x7 access to Cloud Support Engineers, and more extensive support features.

AWS Enterprise On-Ramp Support: This plan offers access to all Trusted Advisor checks as well but is more expensive than the Business Support plan. It is designed for customers running production workloads and needing additional technical support but does not require the full level of engagement that comes with Enterprise Support.

AWS Enterprise Support: This is the most comprehensive and highest-cost support plan, providing access to all Trusted Advisor checks and a full range of AWS Support resources, including a Technical Account Manager (TAM), account management, concierge support, and more.

Conclusion:

The correct answer isB. AWS Business Support, as it provides access to the full set of AWS Trusted Advisor checks at thelowest cost. AWS Developer Support does not offer the complete checks, and both AWS Enterprise On-Ramp and AWS Enterprise Support are higher-cost plans that also provide the full checks.

AWS Shared Responsibility Model

According to the AWS Shared Responsibility Model, AWS is responsible for the security of the cloud, while the customer is responsible for the security in the cloud. This means that AWS is responsible for protecting the infrastructure that runs AWS services, such as DynamoDB, while the customer is responsible for properly configuring the security of the provided service. For abstracted services, such as DynamoDB, the customer is primarily responsible for managing their data, classifying their assets, and using IAM tools to apply the appropriatepermissions12. Therefore, the customer is responsible for controlling the access to DynamoDB tables, such as by creating IAM policies, roles, and users, and using encryption and authentication mechanisms3. References:
