Amazon AWS Certified Solutions Architect - Associate 認定 SAA-C03 試験問題 (Q132-Q137):質問 # 132
A company's application runs on AWS. The application stores large documents in an Amazon S3 bucket that uses the S3 Standard-infrequent Access (S3 Standerd-IA) storage class. The company will continue paying to store the data but wants to save on its total S3 costs. The company wants authorized external users to have the ability to access the documents in milliseconds.
Which solution will meet these requirements MOST cost-effectively?
  • A. Use Amazon CloudFront to handle all the requests to the S3 bucket
  • B. Change the storage tier to S3 Standard for all existing and future objects.
  • C. Turn on S3 Transfer Acceleration tor the S3 Docket
  • D. Configure the S3 bucket to be a Requester Pays bucket
正解：A
解説：
This option is the most efficient because it uses Amazon CloudFront, which is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users1. It also uses CloudFront to handle all the requests to the S3 bucket, which reduces the S3 costs by caching the content at the edge locations and serving it from there. It also allows authorized external users to access the documents in milliseconds, as CloudFront delivers the content with low latency and high data transfer rates. This solution meets the requirement of continuing paying to store the data but saving on its total S3 costs. Option A is less efficient because it configures the S3 bucket to be a Requester Pays bucket, which is a way to shift the cost of data transfer and requests from the bucket owner to the requester2. However, this does not reduce the total S3 costs, as the company still has to pay for storing the data and for any requests made by its own users. Option B is less efficient because it changes the storage tier to S3 Standard for all existing and future objects, which is a way to store frequently accessed data with high durability and availability3. However, this does not reduce the total S3 costs, as S3 Standard has higher storage costs than S3 Standard-IA. Option C is less efficient because it turns on S3 Transfer Acceleration for the S3 bucket, which is a way to speed up transfers into and out of an S3 bucket by routing requests through CloudFront edge locations4. However, this does not reduce the total S3 costs, as S3 Transfer Acceleration has additional charges for data transfer and requests.

質問 # 133
A company runs a shopping application that uses Amazon DynamoDB to store customer information. In case of data corruption, a solutions architect needs to design a solution that meets a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour.
What should the solutions architect recommend to meet these requirements?
  • A. Schedule Amazon Elastic Block Store (Amazon EBS) snapshots for the DynamoDB table every 15 minutes. For RPO recovery, restore the DynamoDB table by using the EBS snapshot.
  • B. Configure DynamoDB point-in-time recovery. For RPO recovery, restore to the desired point in time.
  • C. Export the DynamoDB data to Amazon S3 Glacier on a daily basis. For RPO recovery, import the data from S3 Glacier to DynamoDB.
  • D. Configure DynamoDB global tables. For RPO recovery, point the application to a different AWS Region.
正解：B
解説：

質問 # 134
A company hosts an application in a private subnet. The company has already integrated the application with Amazon Cognito. The company uses an Amazon Cognito user pool to authenticate users.
The company needs to modify the application so the application can securely store user documents in an Amazon S3 bucket.
Which combination of steps will securely integrate Amazon S3 with the application? (Select TWO.)
  • A. Use the existing Amazon Cognito user pool to generate Amazon S3 access tokens for users when they successfully log in.
  • B. Create an Ama2on Cognito identity pool to generate secure Amazon S3 access tokens for users when they successfully log in.
  • C. Attach a policy to the S3 bucket that allows access only from the users' IP addresses.
  • D. Create a NAT gateway in the VPC where the company hosts the application. Assign a policy to the S3 bucket to deny any request that is not initiated from Amazon Cognito.
  • E. Create an Amazon S3 VPC endpoint in the same VPC where the company hosts the application.
正解：B、E
解説：
To securely integrate Amazon S3 with an application that uses Amazon Cognito for user authentication, the following two steps are essential:
Detailed Explanation:
Step 1: Create an Amazon Cognito Identity Pool (Option A)
Amazon Cognito Identity Pools allow users to obtain temporary AWS credentials to access AWS resources, such as Amazon S3, after successfully authenticating with the Cognito user pool. The identity pool bridges the gap between user authentication and AWS service access by generating temporary credentials using AWS Identity and Access Management (IAM).
Once a user logs in using the Cognito User Pool, the identity pool provides IAM roles with specific permissions that the application can use to access S3 securely. This ensures that each user has appropriate access controls while accessing the S3 bucket.
This is a secure way to ensure that users only have temporary and least-privilege access to the S3 bucket for their documents.
Step 2: Create an Amazon S3 VPC Endpoint (Option C)
By creating an Amazon S3 VPC endpoint, the company ensures that communication between the application (which is hosted in a private subnet) and the S3 bucket occurs over the AWS private network, without the need to traverse the internet. This enhances security and prevents exposure of data to public networks.
The VPC endpoint allows the application to access the S3 bucket privately and securely within the VPC. It also ensures that traffic stays within the AWS network, reducing attack surface and improving overall security.
Why the Other Options Are Incorrect:
Option B: This is incorrect because Amazon Cognito User Pools are used for user authentication, not for generating S3 access tokens. To provide S3 access, you need to use Amazon Cognito Identity Pools, which offer AWS credentials.
Option D: A NAT gateway is unnecessary in this scenario. Using a VPC endpoint for S3 access provides a more secure and cost-effective solution by keeping traffic within AWS.
Option E: Attaching a policy to restrict access based on IP addresses is not scalable or efficient. It would require managing users' dynamic IP addresses, which is not an effective security measure for this use case.

質問 # 135
A company collects 10 GB of telemetry data every day from multiple devices. The company stores the data in an Amazon S3 bucket that is in a source data account.
The company has hired several consulting agencies to analyze the company's data. Each agency has a unique AWS account. Each agency requires read access to the company's data.
The company needs a secure solution to share the data from the source data account to the consulting agencies.
Which solution will meet these requirements with the LEAST operational effort?
  • A. Configure cross-account access for the S3 bucket to the accounts that the agencies own.
  • B. Set up an IAM user for each agency in the source data account. Grant each agency IAM user access to the company's S3 bucket.
  • C. Set up an Amazon CloudFront distribution. Use the S3 bucket as the origin.
  • D. Make the S3 bucket public for a limited time. Inform only the agencies that the bucket is publicly accessible.
正解：A
解説：
The most secure and least operationally intensive method is to configure cross-account access using resource-based policies on the S3 bucket. This allows trusted external AWS accounts (consulting agencies) to securely access the S3 data without the need to manage user credentials or build additional infrastructure.
Options A and B pose security risks. Option D increases operational complexity and violates least privilege by managing external users inside your AWS account.

質問 # 136
[Design Secure Architectures]
A company uses a set of Amazon EC2 instances to host a website. The website uses an Amazon S3 bucket to store images and media files.
The company wants to automate website infrastructure creation to deploy the website to multiple AWS Regions. The company also wants to provide the EC2 instances access to the S3 bucket so the instances can store and access data by using AWS Identity and Access Management (IAM).
Which solution will meet these requirements MOST securely?
  • A. Create a file that contains an IAM secret access key and access key ID. Store the file in a new S3 bucket. Create an AWS CloudFormation template. In the template, create a parameter to specify the location of the S3 object that contains the access key and access key ID.
  • B. Create an IAM role and an IAM access policy that allows the web server EC2 instances to access the S3 bucket. Create an AWS CloudFormation template for the web server EC2 instances that contains an IAM instance profile entity that references the IAM role and the IAM access policy.
  • C. Create a script that retrieves an IAM secret access key and access key ID from IAM and stores them on the web server EC2 instances. Include the script in the UserData section of the AWS::EC2::lnstance entity in an AWS CloudFormation template.
  • D. Create an AWS Cloud Format ion template for the web server EC2 instances. Save an IAM access key in the UserData section of the AWS;:EC2::lnstance entity in the CloudFormation template.
正解：B
解説：
The most secure solution for allowing EC2 instances to access an S3 bucket is by usingIAM roles. An IAM role can be created with an access policy that grants the required permissions (e.g., to read and write to the S3 bucket). The IAM role is then associated with the EC2 instances through anIAM instance profile.
By associating the role with the instances, the EC2 instances can securely assume the role and receive temporary credentials via the instance metadata service. This avoids the need to store credentials (such as access keys) on the instances or within the application, enhancing security and reducing the risk of credentials being exposed.
AWS CloudFormation can be used to automate the creation of the entire infrastructure, including EC2 instances, IAM roles, and associated policies.
AWS Reference:
IAM Roles for EC2 Instancesoutlines the use of IAM roles for secure access to AWS services.
AWS CloudFormation User Guidedetails how to create and manage resources using CloudFormation templates.
Why the other options are incorrect:
A . Save IAM access key in UserData: This is insecure because it involves storing long-term credentials in the instance user data, which can be exposed.
B . Store access keys in S3: This is also insecure, as it involves managing and distributing long-term credentials, which should be avoided.
D . Retrieve access keys via a script: This approach is unnecessarily complex and less secure than using IAM roles, which provide temporary credentials automatically.
