質問 # 293
Question:
A company wants to migrate an application that uses a microservice architecture to AWS. The services currently run on Docker containers on-premises. The application has an event-driven architecture that uses Apache Kafka. The company configured Kafka to use multiple queues to send and receive messages. Some messages must be processed by multiple services. Which solution will meet these requirements with the LEAST management overhead?
Options:
正解：D
解説：
Comprehensive and Detailed Explanation:
Amazon Managed Streaming for Apache Kafka (Amazon MSK) is a fully managed service that makes it easy to build and run applications that use Apache Kafka to process streaming data. By using Amazon ECS with the AWS Fargate launch type, you can run containers without managing servers or clusters. This combination reduces operational overhead and provides scalability.
Reference: Power your Kafka Streams application with Amazon MSK and AWS FargateAmazon Web Services, Inc.
質問 # 294
A company needs a backup strategy for its three-tier stateless web application The web application runs on Amazon EC2 instances in an Auto Scaling group with a dynamic scaling policy that is configured to respond to scaling events The database tier runs on Amazon RDS for PostgreSQL The web application does not require temporary local storage on the EC2 instances The company's recovery point objective (RPO) is 2 hours The backup strategy must maximize scalability and optimize resource utilization for this environment Which solution will meet these requirements?
正解：D

質問 # 296
A business plans to deploy an application on EC2 instances within an Amazon VPC and is considering adopting a Network Load Balancer to distribute incoming traffic among the instances. A solutions architect needs to suggest a solution that will enable the security team to inspect traffic entering and exiting their VPC.
Which approach satisfies the requirements?
正解：C
解説：
AWS Network Firewall is a stateful, managed, network firewall, and intrusion detection and prevention service for your virtual private cloud (VPC). With Network Firewall, you can filter traffic at the perimeter of your VPC. This includes traffic going to and coming from an internet gateway, NAT gateway, or over VPN or AWS Direct Connect. Network Firewall uses Suricata - an open-source intrusion prevention system (IPS) for stateful inspection.
The diagram below shows an AWS Network firewall deployed in a single availability zone and traffic flow for a workload in a public subnet:
You can use Network Firewall to monitor and protect your Amazon VPC traffic in a number of ways, including the following:
- Pass traffic through only from known AWS service domains or IP address endpoints, such as Amazon S3.
- Use custom lists of known bad domains to limit the types of domain names that your applications can access.
- Perform deep packet inspection on traffic entering or leaving your VPC.
- Use stateful protocol detection to filter protocols like HTTPS, independent of the port used. Therefore, the correct answer is: Create a firewall using the AWS Network Firewall service at the VPC level then add custom rule groups for inspecting ingress and egress traffic. Update the necessary VPC route tables.
The option that says: Use the Network Access Analyzer service on the application's VPC for inspecting ingress and egress traffic. Create a new Network Access Scope to filter and analyze all incoming and outgoing requests is incorrect. Network Access Analyzer is a feature of VPC that reports on unintended access to your AWS resources based on the security and compliance that you set. This service is not capable of performing deep packet inspection on traffic entering or leaving your VPC, unlike AWS Network Firewall.
The option that says: Create a firewall at the subnet level using the Amazon Detective service. Inspect the ingress and egress traffic using the VPC Reachability Analyzer is incorrect because a firewall must be created at the VPC level and not at the subnet level. Moreover, Amazon Detective can't be used to create a firewall. This service just automatically collects log data from your AWS resources to analyze, investigate, and quickly identify the root cause of potential security issues or suspicious activities in your AWS account. For this scenario, you have to use the AWS Network Firewall instead.
The option that says: Enable Traffic Mirroring on the Network Load Balancer and forward traffic to the instances. Create a traffic mirror filter to inspect the ingress and egress of data that traverses your Amazon VPC is incorrect as this alone accomplishes nothing. It would make more sense if you redirect the traffic to an EC2 instance where an Intrusion Detection System (IDS) is running. Remember that Traffic Mirroring is simply an Amazon VPC feature that you can use to copy network traffic from an elastic network interface. Traffic mirror filters can't inspect the actual packet of the incoming and outgoing traffic.

質問 # 297
A company has a mobile app for customers The app's data is sensitive and must be encrypted at rest The company uses AWS Key Management Service (AWS KMS) The company needs a solution that prevents the accidental deletion of KMS keys The solution must use Amazon Simple Notification Service (Amazon SNS) to send an email notification to administrators when a user attempts to delete a KMS key Which solution will meet these requirements with the LEAST operational overhead''
正解：C
解説：
This solution meets the requirements with the least operational overhead because it uses AWS services that are fully managed and scalable. The EventBridge rule can detect the DeleteKey operation from the AWS KMS API and trigger the Systems Manager Automation runbook, which can execute a predefined workflow to cancel the key deletion. The EventBridge rule can also publish an SNS message to the topic that sends an email notification to the administrators. This way, the company can prevent the accidental deletion of KMS keys and notify the administrators of any attempts to delete them.
Option A is not a valid solution because AWS Config rules are used to evaluate the configuration of AWS resources, not to cancel the deletion of KMS keys. Option B is not a valid solution because it requires creating and maintaining a custom Lambda function that has logic to prevent KMS key deletion, which adds operational overhead. Option D is not a valid solution because it only notifies the administrators of the DeleteKey operation, but does not cancel it.

* Using Amazon SNS for system-to-administrator communications - Amazon Simple Notification Service
