SAA-C03 Exam Dumps : AWS Certified Solutions Architect - Associate (SAA-C03)

This workload has apredictable recurring traffic pattern, so the most operationally efficient solution isscheduled scalingin Amazon EC2 Auto Scaling. AWS documentation states that scheduled actions let you change desired capacity at specific times or on recurring schedules. That is a direct match for weekend peaks from 6 PM to 11 PM. EventBridge plus Lambda would work but adds unnecessary components. Target tracking is better for reactive scaling, while the question describes a predictable pattern that should be handled proactively. Therefore, a scheduled scaling action with recurrence is the best answer.

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

For bursty and seasonal workloads, AWS recommends serverless architectures using Amazon API Gateway + AWS Lambda:

API Gateway exposes a fully managed, scalable API endpoint.

Lambda provides automatic scaling based on request volume, with no need to provision or manage servers.

This is ideal for workloads with variable or seasonal demand, such as end-of-year tax computation bursts.

This combination minimizes operational overhead (no OS patching, no capacity planning) while scaling seamlessly to meet peak demand.

Options A, C, and D rely on EC2 instances. They require capacity planning, scaling configuration, and ongoing management. They do not scale as effortlessly as Lambda for unpredictable or highly seasonal workloads.

AWS Backup Audit Manager automates auditing and reporting of backup activity and compliance, while AWS Config provides visibility into configuration changes. Together, they provide the simplest, most automated, and compliant backup monitoring solution.

From AWS Documentation:

“AWS Backup Audit Manager automatically audits backup activity across AWS resources. You can use predefined or custom frameworks to monitor backup compliance and encryption status.”

(Source: AWS Backup Audit Manager User Guide)

Why D is correct:

Ensures centralized visibility into all backup jobs.

Verifies encryption status automatically.

Generates ready-to-use reports with minimal operational overhead.

Complies with regulatory requirements for data protection.

Why others are incorrect:

A & C: Custom Lambda automation increases maintenance effort.

B: Manual checking is operationally inefficient and error-prone.
