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

Option Aintroduces complexity and does not scale well.

Option Bcreates a read replica, offloading read traffic from the primary RDS instance without impacting the critical application.

Option Cis manual and inefficient.

Option Dmight help for caching frequently queried data but is not ideal for ad-hoc reporting.Therefore, Option B is the best choice.

Amazon CloudFront uses a globally distributed network of edge locations that cache content close to users. When Outposts servers around the world download large software packages, CloudFront provides significantly reduced latency due to edge caching. This is the AWS-recommended solution for accelerating downloads of static files at scale and across global locations.

S3 Transfer Acceleration optimizes uploads and downloads to a single Region but does not provide edge caching. Multi-Region replication with failover does not reduce latency globally because requests still must reach the regional origins. Therefore, CloudFront with caching enabled is the correct design for improving download speed worldwide.

=====================================================

EC2 Image Builder is the AWS-managed service specifically designed to automate the creation, patching, hardening, and testing of AMIs.

For this scenario, best practice is to:

Use EC2 Image Builder pipelines to generate new golden AMIs whenever features are deployed or on a schedule.

Include build components such as update-linux to automatically apply OS security patches and updates during image creation.

Deploy the new AMIs through existing Auto Scaling groups, ensuring that every newly launched instance is already patched and compliant.

This approach:

Prevents OS vulnerabilities from being introduced at deployment time.

Scales across dozens of applications because AMI pipelines are reusable and automated.

Minimizes manual effort and reduces drift between instances.

Amazon Inspector (Option A) identifies vulnerabilities but does not itself patch AMIs.

AWS Backup (Option B) is for data protection, not vulnerability management.

Patch Manager (Option C) patches running instances, but the requirement is to ensure vulnerabilities are not introduced with new AMIs; golden image pipelines with EC2 Image Builder are the recommended solution.
