A metric filter in Amazon CloudWatch Logs can be used to search for specific terms in log data and create metrics based on the matches. To include log events with the word "ERROR" and exclude those with the word "WARNING," the correct syntax involves using a filter pattern with a positive match for "ERROR" and a negation for "WARNING." The correct pattern is "ERROR -WARN," where the minus sign (-) indicates exclusion of log events containing "WARN." According to the WGU Cloud Deployment and Operations Study Guide (Section 4.2, CloudWatch Logs), metric filters use a pattern-based syntax where terms are included or excluded using positive matches and the negation operator (-). This ensures that only logs with "ERROR" and without "WARN" are processed into the metric.

AWS Trusted Advisor provides recommendations to help follow AWS best practices, analyzing the environment for cost optimization, security, performance, and fault tolerance. It offers actionable insights to improve resource usage. The WGU Cloud Deployment and Operations Study Guide (Section 6.4, Trusted Advisor) states, "Trusted Advisor evaluates your AWS environment against best practices, providing recommendations in categories like cost optimization and security (e.g., enabling MFA or removing unused resources)." Options A, B, and C overstate or misrepresent its role, as it does not focus solely on unused IAM roles, holistic health overviews, or patch recommendations.

Multipart uploads must be used when uploading files larger than 5 GB to Amazon S3, as this method splits the file into smaller parts for parallel upload, improving reliability and performance. The WGU Cloud Deployment and Operations Study Guide (Section 2.1, S3 Uploads) states, "For files exceeding 5 GB, multipart upload is required in S3, allowing the file to be divided into parts (minimum 5 MB each) for concurrent uploads, ensuring efficient and resumable transfers." Glacier Select, Transfer Acceleration, and Intelligent-Tiering are not designed for this upload optimization.
