A payment processing company records all voice communication with its customers and stores the audio files in an Amazon S3 bucket. The company needs to capture the text from the audio files. The company must remove from the text any personally identifiable information (Pll) that belongs to customers.

What should a solutions architect do to meet these requirements?

A. Process the audio files by using Amazon Kinesis Video Streams. Use an AWS Lambda function to scan for known Pll patterns.

B. When an audio file is uploaded to the S3 bucket, invoke an AWS Lambda function to start an Amazon Textract task to analyze the call recordings.

C. Configure an Amazon Transcribe transcription job with Pll redaction turned on. When an audio file is uploaded to the S3 bucket, invoke an AWS Lambda function to start the transcription job. Store the output in a separate S3 bucket.

D. Create an Amazon Connect contact flow that ingests the audio files with transcription turned on. Embed an AWS Lambda function to scan for known Pll patterns. Use Amazon EventBridge (Amazon CloudWatch Events) to start the contact flow when an audio file is uploaded to the S3 bucket.

A company has an event-driven application that invokes AWS Lambda functions up to 800 times each minute with varying runtimes. The Lambda functions access data that is stored in an Amazon Aurora MySQL OB cluster. The company is noticing connection timeouts as user activity increases The database shows no signs of being overloaded. CPU. memory, and disk access metrics are all low.

Which solution will resolve this issue with the LEAST operational overhead?

A. Adjust the size of the Aurora MySQL nodes to handle more connections. Configure retry logic in the Lambda functions for attempts to connect to the database

B. Set up Amazon ElastiCache tor Redls to cache commonly read items from the database. Configure the Lambda functions to connect to ElastiCache for reads.

C. Add an Aurora Replica as a reader node. Configure the Lambda functions to connect to the reader endpoint of the OB cluster rather than lo the writer endpoint.

D. Use Amazon ROS Proxy to create a proxy. Set the DB cluster as the target database Configure the Lambda functions lo connect to the proxy rather than to the DB cluster.

Lo que pasa es que aurora tiene limite conexiones abiertas por lo que un proxy funcionaría de intermediario.

• En lugar de abrir una nueva conexión para cada solicitud, RDS Proxy reutiliza conexiones existentes.
• Esto reduce la sobrecarga de creación y cierre de conexiones.
• Útil para cargas intermitentes como AWS Lambda, donde cada invocación genera una nueva conexión.
