Amazon AWS Certified Solutions Architect - Associate 認定 SAA-C03 試験問題 (Q342-Q347):

質問 # 342
A retail company has several businesses. The IT team for each business manages its own AWS account. Each team account is part of an organization in AWS Organizations. Each team monitors its product inventory levels in an Amazon DynamoDB table in the team's own AWS account.
The company is deploying a central inventory reporting application into a shared AWS account. The application must be able to read items from all the teams' DynamoDB tables.
Which authentication option will meet these requirements MOST securely?

正解：C

解説：
This solution meets the requirements most securely because it uses IAM roles and the STS AssumeRole API operation to authenticate and authorize the inventory application to access the DynamoDB tables in different accounts. IAM roles are more secure than IAM users or certificates because they do not require long-term credentials or passwords. Instead, IAM roles provide temporary security credentials that are automatically rotated and can be configured with a limited duration. The STS AssumeRole API operation enables you to request temporary credentials for a role that you are allowed to assume. By using this operation, you can delegate access to resources that are in different AWS accounts that you own or that are owned by third parties. The trust policy of the role defines which entities can assume the role, and the permissions policy of the role defines which actions can be performed on the resources. By using this solution, you can avoid hard-coding credentials or certificates in the inventory application, and you can also avoid storing them in Secrets Manager or ACM. You can also leverage the built-in security features of IAM and STS, such as MFA, access logging, and policy conditions.

質問 # 343
A company is building a web-based application running on Amazon EC2 instances in multiple Availability Zones. The web application will provide access to a repository of text documents totaling about 900 TB in size. The company anticipates that the web application will experience periods of high demand. A solutions architect must ensure that the storage component for the text documents can scale to meet the demand of the application at all times. The company is concerned about the overall cost of the solution.
Which storage solution meets these requirements MOST cost-effectively?

正解：D

解説：
Explanation
Amazon S3 is cheapest and can be accessed from anywhere.


質問 # 344
A company stores data in Amazon S3. According to regulations, the data must not contain personally identifiable information (PII). The company recently discovered that S3 buckets have some objects that contain PII. The company needs to automatically detect PII in S3 buckets and to notify the company's security team. Which solution will meet these requirements?

正解：D

解説：
* Amazon Macie: Detects sensitive data such as PII in S3 buckets using machine learning.
* EventBridge Rule: Filters Macie findings for specific sensitive data events (e.g., SensitiveData).
* SNS Notification: Provides real-time alerts to the security team for immediate action.: Amazon Macie Documentation, Amazon EventBridge Documentation


質問 # 345
A company hosts an application on Amazon EC2 instances that are part of a target group behind an Application Load Balancer (ALB). The company has attached a security group to the ALB.
During a recent review of application logs, the company found many unauthorized login attempts from IP addresses that belong to countries outside the company's normal user base. The company wants to allow traffic only from the United States and Australia. Which solution will meet this requirement?

正解：D

解説：
Why Option B is Correct:
AWS WAF: Provides a simple way to create geographic match rules to block or allow traffic based on country IP ranges.
Least Operational Overhead: Attaching the WAF rule to the ALB ensures centralized control without modifying ACLs or instance firewalls.
Why Other Options Are Not Ideal:
Option A: Network ACLs operate at the subnet level and can become complex to manage for dynamic or evolving IP ranges.
Option C: Managing IP-based rules in security groups and ACLs lacks scalability and does not provide country-based filtering.
Option D: Configuring host-based firewalls increases operational overhead and does not leverage AWS-managed solutions.


質問 # 346
A company is implementing new data retention policies for all databases that run on Amazon RDS DB instances. The company must retain daily backups for a minimum period of 2 years. The backups must be consistent and restorable.
Which solution should a solutions architect recommend to meet these requirements?

正解：D

解説：
AWS Backup is a fully managed service that enables users to centralize and automate the backup of data across AWS services. It can create and manage backup plans that specify the frequency and retention period of backups. It can also assign backup resources to backup vaults, which are containers that store backup data1.
By using AWS Backup, the solution can ensure that the RDS backups are consistent, restorable, and retained for a minimum period of 2 years.
B:Configure a backup window for the RDS DB instances for daily snapshots. Assign a snapshot retention policy of 2 years to each RDS DB instance. Use Amazon Data Lifecycle Manager (Amazon DLM) to schedule snapshot deletions. This solution will not meet the requirement of ensuring that the backupsare consistent and restorable, as Amazon DLM is not compatible with RDS snapshots and cannot be used to schedule snapshot deletions2.
C:Configure database transaction logs to be automatically backed up to Amazon CloudWatch Logs with an expiration period of 2 years. This solution will not meet the requirement of ensuring that the backups are consistent and restorable, as database transaction logs are not sufficient to restore a database to a point in time. They only capture the changes made to the database, not the full state of the database3.
D:onfigure an AWS Database Migration Service (AWS DMS) replication task. Deploy a replication instance, and configure a change data capture (CDC) task to stream database changes to Amazon S3 as the target. Configure S3 Lifecycle policies to delete the snapshots after 2 years. This solution will not meet the requirement of ensuring that the backups are consistent and restorable, as AWS DMS is a service that helps users migrate databases to AWS, not back up databases. It also requires additional resources and configuration, such as replication instances and CDC tasks.
