A company has an on-premises monitoring solution using a PostgreSQL database for persistence of events. The database is unable to scale due to heavy ingestion and it frequently runs out of storage. The company wants to create a hybrid solution and has already set up a VPN connection between its network and AWS. The solution should include the following attributes: Managed AWS services to minimize operational complexity. A buffer that automatically scales to match the throughput of data and requires no ongoing administration. A visualization tool to create dashboards to observe events in near-real time. Support for semi-structured JSON data and dynamic schemas. Which combination of components will enable the company to create a monitoring solution that will satisfy these requirements? (Choose two.)

Use Amazon Kinesis Data Firehose to buffer events. Create an AWS Lambda function to process and transform events.

Question 308

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?

Use AWS data Pipeline to schedule a DynamoDB cross region copy once a day, create a “Lastupdated” attribute in your DynamoDB table that would represent the timestamp of the last update and use it as a filter.

Use EMR and write a custom script to retrieve data from DynamoDB in the current region using a SCAN operation and push it to DynamoDB in the second region.

Use AWS data Pipeline to schedule an export of the DynamoDB table to S3 in the current region once a day then schedule another task immediately after it that will import data from S3 to DynamoDB in the other region.

Send also each Ante into an SQS queue in me second region; use an auto-scaling group behind the SQS queue to replay the write in the second region.
