Amazon Web Services SAP-C02 Exam With Confidence Using Practice Dumps

The correct approach involves activating the BusinessUnit cost allocation tag in the management account to ensure costs are tagged consistently across the organization.

The AWS Cost and Usage Report (CUR), delivered to a single Amazon S3 bucket in the management account, consolidates cost and usage data across all member accounts.

Amazon Athena can efficiently query the CUR data directly from S3, while Amazon QuickSight can be used to create interactive dashboards and reports that visualize the cost allocation by business unit.

This solution minimizes complexity, centralizes reporting, and leverages AWS native services for the best cost optimization and insights.

Enable DynamoDB Auto Scaling:

Navigate to the DynamoDB console and select the table experiencing high demand.

Go to the " Capacity " tab and enable auto scaling for both read and write capacity units. Auto scaling adjusts the provisioned throughput capacity automatically in response to actual traffic patterns, ensuring the table can handle the increased load.

Configure Auto Scaling Policies:

Set the minimum and maximum capacity units to define the range within which auto scaling can adjust the provisioned throughput.

Specify target utilization percentages for read and write operations, typically around 70%, to maintain a balance between performance and cost.

Monitor and Adjust:

Use Amazon CloudWatch to monitor the auto scaling activity and ensure it is effectively handling the increased demand.

Adjust the auto scaling settings if necessary to better match the traffic patterns and application requirements.

By enabling DynamoDB auto scaling, you ensure that the database can handle the fluctuating traffic volumes without manual intervention, improving response times and reducing errors.

Adding an accelerator in AWS Global Accelerator will enable improving the performance of the APIs for local and global users1. AWS Global Accelerator is a service that uses the AWS global network to route traffic to the optimal regional endpoint based on health, client location, and policies1. Configuring the ALB as the origin will enable connecting the accelerator to the ALB that exposes the APIs2. AWS Global Accelerator supports non-standard REST methods such as LINK, UNLINK, LOCK, and UNLOCK3.
