                                        Amazon AWS Certified Solutions Architect - Associate (SAA-C03) 認定 AWS-Solutions-Associate 試験問題 (Q432-Q437):

                                        質問 # 432
                                        A company's web application uses an Amazon RDS PostgreSQL DB instance to store its application data.
                                        During the financial closing period at the start of every month. Accountants run large queries that impact the database's performance due to high usage. The company wants to minimize the impact that the reporting activity has on the web application.
                                        What should a solutions architect do to reduce the impact on the database with the LEAST amount of effort?

                                        正解：A

                                        解説：
                                        Explanation
                                        https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ReadRepl.html Amazon RDS uses the MariaDB, MySQL, Oracle, PostgreSQL, and Microsoft SQL Server DB engines' built-in replication functionality to create a special type of DB instance called a read replica from a source DB instance. Updates made to the source DB instance are asynchronously copied to the read replica. You can reduce the load on your source DB instance by routing read queries from your applications to the read replica.
                                        When you create a read replica, you first specify an existing DB instance as the source. Then Amazon RDS takes a snapshot of the source instance and creates a read-only instance from the snapshot. Amazon RDS then uses the asynchronous replication method for the DB engine to update the read replica whenever there is a change to the source DB instance. The read replica operates as a DB instance that allows only read-only connections. Applications connect to a read replica the same way they do to any DB instance. Amazon RDS replicates all databases in the source DB instance.

                                        質問 # 433
                                        A solutions architect is building a static website hosted on Amazon S3. The website uses an Amazon Aurora PostgreSQL database accessed through an AWS Lambda function. The production website uses a Lambda alias that points to a specific version of the Lambda function.
                                        Database credentials must rotate every 2 weeks. Previously deployed Lambda versions must always use the most recent credentials.
                                        Which solution will meet these requirements?

                                        正解：D

                                        解説：
                                        AWS Secrets Manager is the recommended service for storing database credentials and performing automated rotation. Any Lambda function version or alias can fetch the latest secret value at runtime, ensuring no outdated credentials exist in deployed versions.
                                        Environment variables (Option C) are static per version. Embedding credentials in code (Option B) is insecure and requires redeployment. Parameter Store (Option D) supports rotation but requires more configuration and is not as seamless as Secrets Manager for database credential rotation.


                                        質問 # 434
                                        An International company has deployed a multi-tier web application that relies on DynamoDB in a single region For regulatory reasons they need disaster recovery capability In a separate region with a Recovery Time Objective of 2 hours and a Recovery Point Objective of 24 hours They should synchronize their data on a regular basis and be able to provision me web application rapidly using CloudFormation.
                                        The objective is to minimize changes to the existing web application, control the throughput of DynamoDB used for the synchronization of data and synchronize only the modified elements.
                                        Which design would you choose to meet these requirements?

                                        正解：C


                                        質問 # 435
                                        A solutions architect is optimizing a website for an upcoming musical event. Videos of the performances will be streamed in real time and then will be available on demand. The event is expected to attract a global online audience.
                                        Which service will improve the performance of both the real-lime and on-demand streaming?

                                        正解：B

                                        解説：
                                        Explanation
                                        You can use CloudFront to deliver video on demand (VOD) or live streaming video using any HTTP origin.
                                        One way you can set up video workflows in the cloud is by using CloudFront together with AWS Media Services.
                                        https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/on-demand-streaming-video.html


                                        質問 # 436
                                        Your customer wishes to deploy an enterprise application to AWS, which will consist of several web servers, several application servers and a small (50GB) Oracle database. Information is stored, both in the database and the file systems of the various servers. The backup system must support database recovery whole server and whole disk restores, and individual file restores with a recovery time of no more than two hours. They have chosen to use RDS Oracle as the database.
                                        Which backup architecture will meet these requirements?

                                        正解：D

                                        解説：
                                        Point-In-Time Recovery
                                        In addition to the daily automated backup, Amazon RDS archives database change logs. This enables you to recover your database to any point in time during the backup retention period, up to the last five minutes of database usage.
                                        Amazon RDS stores multiple copies of your data, but for Single-AZ DB instances these copies are stored in a single availability zone. If for any reason a Single-AZ DB instance becomes unusable, you can use point- in-time recovery to launch a new DB instance with the latest restorable data. For more information on working with point-in-time recovery, go to Restoring a DB Instance to a Specified Time.
                                        Note
                                        Multi-AZ deployments store copies of your data in different Availability Zones for greater levels of data durability. For more information on Multi-AZ deployments, see High Availability (Multi-AZ).
