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 loggingB: Use only CPU instances, manual scaling, quarterly auditsC: Continue current setup without changesD: 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 variantsAnswer: DExplanation: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 SecurityQuestion Type: Case-StudyQuestion 2Task: Match the data cleaning technique to the scenario:Use median imputation for missing values in skewed distributionsApply IQR method for outlier detectionImplement deduplication using composite keysMerge datasets using inner joinQuestion:Which AWS services enable validation and quality checks on data before model training?Options:A: Amazon SageMaker StudioB: AWS Glue Data QualityC: Amazon CloudWatchD: AWS Glue DataBrewAnswer: B, DExplanation:A: SageMaker Studio is an ML IDE and doesn’t provide built-in data validation rules.B: AWS Glue Data Quality supports automated validation, completeness checks, and data profiling before pipeline execution, making it ideal for pre-training validation.C: CloudWatch focuses on infrastructure and application metrics, not dataset validation.D: Glue DataBrew visually profiles and cleans data, detecting missing values, skewness, and anomalies — ensuring datasets meet model input standards.Domain: Data Preparation for MLQuestion Type: Service-BasedQuestion 3Question:What is the primary benefit of using Amazon SageMaker Feature Store for managing machine learning features?Options:A: Automated hyperparameter tuningB: Real-time model deploymentC: Version control for training scriptsD: Centralized feature repository with online and offline storesAnswer: DExplanation:A: Hyperparameter tuning is handled by SageMaker Automatic Model Tuning, not Feature Store.B: Model deployment is performed via SageMaker endpoints, not Feature Store.C: Script versioning is managed externally (e.g., with Git).D: Feature Store provides a unified feature repository with online (low-latency) and offline (batch) stores, ensuring consistent features for training and inference.Domain: Data Preparation for MLQuestion Type: ConceptQuestion 4Task: Order the steps for ingesting streaming data into AWS for ML processing:Configure Kinesis Data StreamSet up S3 bucketCreate Data Firehose delivery streamDefine data transformation LambdaOptions:A: 2, 3, 1, 4B: 1, 3, 4, 2C: 3, 1, 2, 4D: 4, 1, 3, 2Answer: BExplanation:A: Setting up S3 first doesn’t establish the streaming pipeline flow.B: Correct order begins by configuring the Kinesis Data Stream, then setting up Data Firehose for delivery, defining transformation logic with Lambda, and finally creating the S3 bucket for storage.C: Starting with Firehose before its data source causes dependency issues.D: Defining transformations before streams exist disrupts the logical flow of data ingestion.Domain: Data Preparation for MLQuestion Type: OrderingPreparation Strategy & Study GuidanceUnderstand the Concepts, Not Just the Questions: Use mock exams to identify weak areas but supplement with the official AWS MLA-C01 guide.Target 80%+ in Practice Tests: Real exam passing score is 700;
