Amazon Web Services SAA-C03 Exam With Confidence Using Practice Dumps

Because the application is public and serves global customers with dynamic IP addresses, the web tier must allow HTTPS traffic from0.0.0.0/0on port 443. For the database tier, the secure design is to allow MySQL access only from theweb tier’s security group, not from the internet. AWS RDS documentation explains that you can specify another VPC security group as the source for the DB security group, which allows application servers to connect without exposing the database publicly. That makes A the correct configuration. Options B and C do not work well for global dynamic users, and D exposes the database to the internet.

The correct answer is to useIAM roles with fine-grained permissions. AWS recommends temporary credentials and least-privilege access instead of shared accounts or long-term access keys. Assigning a separate role to each developer gives the company strong access isolation, simpler auditing, and the ability to restrict each developer to only the AWS actions they need. Shared IAM user credentials are insecure because actions cannot be tied reliably to one person. Long-term access keys increase credential management risk. Amazon Cognito is primarily for application end users, not for granting internal developers administrative access to AWS resources. Using IAM roles is the standard AWS security best practice for controlled workforce access.

AWS Service Catalogallows organizations to centrally manage commonly deployed IT services and offers self-service deployment capabilities to customers. By creatingService Catalog products, the consulting company can package their solutions and tools for easy reuse by customers while maintaining central control over configuration and access. This provides a standardized and automated solution with the least operational overhead for managing and deploying solutions across different customers.

Option A (CloudFormation): CloudFormation templates are useful but don ' t provide the same level of management and user-friendly self-service capabilities as Service Catalog.

Option C (Systems Manager): Systems Manager is more focused on managing infrastructure and doesn ' t offer the same self-service capabilities.

Option D (AWS Config): AWS Config is used for tracking resource configurations, not for deploying solutions.
