最新的 AWS Certified Solutions Architect SAA-C03 免費考試真題 (Q119-Q124):

問題 #119
A company is designing an IPv6 application that is hosted on Amazon EC2 instances in a private subnet within a VPC. The application will store user-uploaded content in Amazon S3 buckets. The application will save each S3 object's URL link and metadata in Amazon DynamoDB.
The company must not use public internet connections to transmit user-uploaded content or metadata.
Which solution will meet these requirements?

A. Implement gateway VPC endpoints for both Amazon S3 and Amazon DynamoDB.
B. Implement a gateway VPC endpoint for Amazon S3 and an interface VPC endpoint for Amazon DynamoDB.
C. Implement a gateway VPC endpoint for Amazon DynamoDB and an interface VPC endpoint for Amazon S3.
D. Implement interface VPC endpoints for both Amazon S3 and Amazon DynamoDB.

答案：B

解題說明：
Amazon S3 uses gateway VPC endpoints, which enable private, secure access to S3 without traversing the internet, compatible with IPv6.
Amazon DynamoDB uses interface VPC endpoints (powered by AWS PrivateLink) for private connectivity within the VPC.
Therefore, for secure private communication without public internet, the correct solution is to implement a gateway VPC endpoint for S3 and an interface VPC endpoint for DynamoDB.
Option B is incorrect because S3 does not support interface endpoints; Option C is incorrect because DynamoDB does not support gateway endpoints. Option D reverses the correct endpoint types.
Reference:
VPC Endpoints for Amazon S3 (https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints-s3.html) VPC Endpoints for DynamoDB (https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints-dynamodb.html)

問題 #120
A company operates an online photo-sharing service and stores data in AWS Account A in a centralized Amazon S3 bucket. The company wants to grant a second AWS account named Account B access to the centralized S3 bucket. The company owns Account B. Which solution will meet this requirement?

A. Enable S3 Transfer Acceleration to provide Account B access to the centralized S3 bucket in Account A.
B. Use Amazon CloudFront to distribute the S3 bucket contents. Grant Account B access to the bucket contents through a signed URL.
C. Enable cross-Region replication between Account A and Account B to share the S3 bucket data.
D. Create a bucket policy that grants Account B permission to access the centralized S3 bucket in Account A.

答案：D

解題說明：
To grant cross-account access to an Amazon S3 bucket, you can use a bucket policy that specifies the AWS account ID of the account you want to grant access to. This method allows Account B to access the S3 bucket in Account A without the need for additional services or configurations.

問題 #121
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?

A. Create a backup vault in AWS Backup to retain RDS backups. Create a new backup plan with a daily schedule and an expiration period of 2 years after creation. Assign the RDS DB instances to the backup plan.
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.
C. Configure database transaction logs to be automatically backed up to Amazon CloudWatch Logs with an expiration period of 2 years.
D. Configure 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.

答案：A

問題 #122
A company is building a new web-based customer relationship management application. The application will use several Amazon EC2 instances that are backed by Amazon EBS volumes behind an Application Load Balancer (ALB). The application will also use an Amazon Aurora database. All data for the application must be encrypted at rest and in transit.
Which solution will meet these requirements?

A. Use AWS KMS certificates on the ALB to encrypt data in transit. Use AWS Certificate Manager (ACM) to encrypt the EBS volumes and Aurora database storage at rest.
B. Use BitLocker to encrypt all data at rest. Import the company ' s TLS certificate keys to AWS KMS.Attach the KMS keys to the ALB to encrypt data in transit.
C. Use AWS KMS to encrypt the EBS volumes and Aurora database storage at rest. Attach an AWS Certificate Manager (ACM) certificate to the ALB to encrypt data in transit.
D. Use the AWS root account to log in to the AWS Management Console. Upload the company ' s encryption certificates. While in the root account, select the option to turn on encryption for all data at rest and in transit for the account.

答案：C

解題說明：
The correct answer isCbecause the requirement separates encryption into two parts:encryption at restandencryption in transit. Fordata at rest, AWS usesAWS Key Management Service (AWS KMS)to manage encryption keys for services such asAmazon EBSandAmazon Aurora. EBS volumes can be created as encrypted volumes by using KMS keys, and Aurora supports encryption at rest through KMS as well. This protects stored application and database data without requiring the company to build its own key management system.
Fordata in transit, the proper AWS service isAWS Certificate Manager (ACM). AnApplication Load Balancercan use an ACM-issued or ACM-imported SSL/TLS certificate to terminate HTTPS connections and encrypt traffic between clients and the load balancer. This is the AWS standard approach for securing web traffic to internet-facing applications.
Option A is incorrect because it reverses the roles of the services.KMS does not provide certificates for TLS termination on an ALB, andACM does not encrypt EBS or Aurora storage at rest. Option B is incorrect because there is no single account-wide console setting that automatically turns on all encryption for all services in this way, and use of the root account is not an AWS best practice for normal configuration tasks.
Option D is incorrect becauseBitLockeris not the appropriate general AWS-native answer for EBS and Aurora encryption, and ALBs do not use KMS keys directly as TLS certificates.
AWS security best practices recommendKMS for encryption at restandACM certificates for encryption in transit. Therefore, optionCis the correct solution.

問題 #123
A company runs game applications on AWS. The company needs to collect, visualize, and analyze telemetry data from the company's game servers. The company wants to gain insights into the behavior, performance, and health of game servers in near real time. Which solution will meet these requirements?

A. Use Amazon Data Firehose to collect, process, and store telemetry data in near real time. Use AWS Glue to extract, transform, and load (ETL) data from Firehose into required formats for analysis. Use Amazon QuickSight to visualize and analyze the data.
B. Use Amazon Kinesis Data Streams to collect, process, and store telemetry data. Use Amazon EMR to process the data in near real time into required formats for analysis. Use Amazon Athena to analyze and visualize the data.
C. Use Amazon DynamoDB Streams to collect and store telemetry data. Configure DynamoDB Streams to invoke AWS Lambda functions to process the data in near real time. Use Amazon Managed Grafana to visualize and analyze the data.
D. Use Amazon Kinesis Data Streams to collect telemetry data. Use Amazon Managed Service for Apache Flink to process the data in near real time and publish custom metrics to Amazon CloudWatch. Use Amazon CloudWatch to create dashboards and alarms from the custom metrics.

答案：D

解題說明：
Amazon Kinesis Data Streams with Amazon Managed Service for Apache Flink enables near real-time collection and processing of telemetry data. Publishing custom metrics to CloudWatch allows for dashboards and alarms, providing actionable insights into server behavior, performance, and health with minimal operational overhead.
