Question 94

Exam Question

An application is using an Amazon RDS for MySQL Multi-AZ DB instance in the us-east-1 Region. After a failover test, the application lost the connections to the database and could not re-establish the connections. After a restart of the application, the application re-established the connections.

A solutions architect must implement a solution so that the application can re-establish connections to the database without requiring a restart.

Which solution will meet these requirements?

A. Create an Amazon Aurora MySQL Serverless v1 DB instance. Migrate the RDS DB instance to the Aurora Serverless v1 DB instance. Update the connection settings in the application to point to the Aurora reader endpoint.

B. Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.

C. Create a two-node Amazon Aurora MySQL DB cluster. Migrate the RDS DB instance to the Aurora DB cluster. Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.

D. Create an Amazon S3 bucket. Export the database to Amazon S3 by using AWS Database Migration Service (AWS DMS). Configure Amazon Athena to use the S3 bucket as a data store. Install the latest Open Database Connectivity (ODBC) driver for the application. Update the connection settings in the application to point to the Athena endpoint

Correct Answer

B. Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.

Explanation

Creating an RDS Proxy and configuring the existing RDS endpoint as a target, and then updating the connection settings in the application to point to the RDS proxy endpoint will meet the requirement of the application being able to re-establish connections to the database without requiring a restart.

Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon RDS that makes applications more scalable, more resilient to database failures, and more secure. With RDS Proxy, applications can pool and share connections to RDS databases, reducing the number of connections each RDS instance needs to handle. This can improve the performance and scalability of the application.

In the event of a failover or interruption, RDS Proxy automatically redirects connections to the new primary instance, so the application can continue to function without interruption. RDS Proxy also provides connection pooling, which reduces the number of connections to the primary RDS instance, so the primary instance can handle more traffic.

Here is an example of how to set up an RDS proxy and configure it to work with an existing RDS instance:

Create an RDS proxy in the AWS Management Console, and configure it to use the existing RDS instance as a target.
Update the connection settings in the application to use the RDS proxy endpoint instead of the RDS instance endpoint.

Question 96

Exam Question

A video streaming company recently launched a mobile app for video sharing. The app uploads various files to an Amazon S3 bucket in the us-east-1 Region. The files range in size from 1 GB to 10 GB.

Users who access the app from Australia have experienced uploads that take long periods of time. Sometimes the files fail to completely upload for these users. A solutions architect must improve the app’s performance for these uploads.

Which solutions will meet these requirements? (Choose two.)

A. Enable S3 Transfer Acceleration on the S3 bucket. Configure the app to use the Transfer Acceleration endpoint for uploads.

B. Configure an S3 bucket in each Region to receive the uploads. Use S3 Cross-Region Replication to copy the files to the distribution S3 bucket.

C. Set up Amazon Route 53 with latency-based routing to route the uploads to the nearest S3 bucket Region.

D. Configure the app to break the video files into chunks. Use a multipart upload to transfer files to Amazon S3.

E. Modify the app to add random prefixes to the files before uploading.

Correct Answer

A. Enable S3 Transfer Acceleration on the S3 bucket. Configure the app to use the Transfer Acceleration endpoint for uploads.

D. Configure the app to break the video files into chunks. Use a multipart upload to transfer files to Amazon S3.

Explanation

Enabling S3 Transfer Acceleration on the S3 bucket and configuring the app to use the Transfer Acceleration endpoint for uploads will improve the app’s performance for these uploads by leveraging Amazon CloudFront’s globally distributed edge locations to accelerate the uploads. Breaking the video files into chunks and using a multipart upload to transfer files to Amazon S3 will also improve the app’s performance by allowing parts of the file to be uploaded in parallel, reducing the overall upload time.

Question 97

Exam Question

A company runs an IoT platform on AWS. IoT sensors in various locations send data to the company’s Node.js API servers on Amazon EC2 instances running behind an Application Load Balancer. The data is stored in an Amazon RDS MySQL DB instance that uses a 4 TB General Purpose SSD volume.

The number of sensors the company has deployed in the field has increased over time, and is expected to grow significantly. The API servers are consistently overloaded and RDS metrics show high write latency.

Which of the following steps together will resolve the issues permanently and enable growth as new sensors are provisioned, while keeping this platform cost-efficient? (Choose two.)

A. Resize the MySQL General Purpose SSD storage to 6 TB to improve the volume’s IOPS.

B. Re-architect the database tier to use Amazon Aurora instead of an RDS MySQL DB instance and add read replicas.

C. Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data.

D. Use AWS X-Ray to analyze and debug application issues and add more API servers to match the load.

E. Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance.

Correct Answer

C. Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data.

E. Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance.

Explanation

Option C is correct because leveraging Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data resolves the issues permanently and enable growth as new sensors are provisioned.

Amazon Kinesis Data Streams is a serverless streaming data service that simplifies the capture, processing, and storage of data streams at any scale. Kinesis Data Streams can handle any amount of streaming data and process data from hundreds of thousands of sources with very low latency. AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers.

Lambda can be triggered by Kinesis Data Streams events and process the data records in real time.

Lambda can also scale automatically based on the incoming data volume. By using Kinesis Data Streams and Lambda, the company can reduce the load on the API servers and improve the performance and scalability of the data ingestion and processing layer3 Option E is correct because re-architecting the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance resolves the issues permanently and enable growth as new sensors are provisioned. Amazon DynamoDB is a fully managed key-value and document database that delivers single-digit millisecond performance at any scale. DynamoDB supports auto scaling, which automatically adjusts read and write capacity based on actual traffic patterns. DynamoDB also supports on-demand capacity mode, which instantly accommodates up to double the previous peak traffic on a table. By using DynamoDB instead of RDS MySQL DB instance, the company can eliminate high write latency and improve scalability and performance of the database tier.
