Sample Practice Questions
Question 1
A global e-commerce company operates a recommendation system serving millions of users. The system experiences performance degradation, increased costs, and occasional bias in recommendations. The ML team must optimize the entire solution while ensuring fairness, security, and cost efficiency. The current architecture uses SageMaker endpoints on large GPU instances, processes data daily with AWS Glue, stores features in S3, and lacks comprehensive monitoring.
Question:
Which combination of actions addresses all maintenance and optimization requirements?
Options:
A: Migrate to Lambda, use EC2 for training, disable logging
B: Use only CPU instances, manual scaling, quarterly audits
C: Continue current setup without changes
D: Implement SageMaker Model Monitor and Clarify for drift and bias detection, use Inference Recommender to optimize instance types, enable multi-model endpoints to reduce costs, configure CloudWatch alarms for performance metrics, implement VPC isolation with least-privilege IAM roles, enable CloudTrail and Config for audit compliance, use Cost Explorer with tagging for cost allocation, establish A/B testing for model variants
Answer: D
Explanation:
A: Lambda is unsuitable for large inference workloads due to execution time and memory limits. EC2 requires manual management, and disabling logging removes visibility and compliance tracking.
B: CPU-only setups may underperform for deep learning models, and manual scaling increases operational overhead. Quarterly audits are too infrequent for proactive compliance.
C: The current system already shows inefficiencies and lacks monitoring, so maintaining the status quo won’t resolve issues.
D: This end-to-end optimization covers all areas: Model Monitor and Clarify ensure bias and drift detection; Inference Recommender optimizes instance types; multi-model endpoints reduce cost; CloudWatch enhances observability; VPC and IAM strengthen security; CloudTrail and Config provide compliance tracking; Cost Explorer supports cost allocation; A/B testing validates performance improvements.
Domain: ML Solution Monitoring, Maintenance, and Security
Question Type: Case-Study
Who Should Take This Course
"AWS Machine Learning MLA-C01 - Mock Tests 390 Questions 2025" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 5/5 rating on Udemy from 0+ students who've already enrolled. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
