AWS Systems Manager offers the capability to automate patching for Amazon EC2 instances, including Windows instances, through Patch Manager. It can automate patching tasks, schedule updates, and apply patches based on specified baselines. AWS Organizations and Control Tower focus on account management and governance, while Elastic Load Balancing (ELB) is unrelated to patch management.

The reliability pillar of the AWS Well-Architected Framework emphasizes building systems that can recover from failures and dynamically adjust to meet demand. This includes designing to automatically recover from failures and implementing mechanisms to manage capacity demands, avoiding manual guesswork. The other options do not align with core reliability principles, as operating in a single Availability Zone or preemptively adjusting quotas in a secondary region does not inherently improve reliability.

AWS recommends using tags to organize resources effectively and to activate cost allocation tags to enable detailed tracking of costs by categories such as department, environment, and application. This approach provides the granularity needed for tracking and managing AWS costs accurately. AWS Cost Management and Billing tools provide insights but do not inherently categorize costs without tags.

AWS Migration Hub assists users in planning and tracking the progress of their server and application migrations. It centralizes migration tracking across various AWS services, providing visibility into application inventory and migration status. While AWS Application Migration Service also assists with migrations, Migration Hub is specifically designed for tracking migration data comprehensively.

AWS Fargate and Amazon S3 are both serverless services. Fargate allows users to run containers without managing the underlying infrastructure, while S3 provides object storage without the need for provisioning or managing servers. Amazon EC2, Amazon Managed Streaming for Apache Kafka, and Amazon EMR involve server management to varying degrees and are not serverless by nature.

The AWS Cloud is cost-effective for dynamic workloads because of its elasticity, allowing resources to scale up or down based on demand, and its pay-as-you-go pricing, which enables companies to pay only for what they use. Reliability, security, and high availability are also benefits of AWS, but they do not specifically relate to cost-effectiveness in the context of dynamic workloads.

AWS Application Discovery Service helps companies gather information about on-premises data centers to support migration planning. It collects data on system configuration, resource utilization, and network dependencies, providing essential insights for migration. AWS DataSync and Storage Gateway are used for data transfer, while AWS DMS is for database migration specifically.

AWS Storage Gateway provides on-premises applications with low-latency access to data stored in AWS by caching frequently accessed data locally. It seamlessly integrates on-premises environments with cloud storage, enabling hybrid storage solutions. AWS DataSync is for data transfer, CloudFront is a content delivery network, and AWS Backup is for backup management, not low-latency access.

A VPC endpoint enables private connections between an Amazon VPC and AWS services, like Amazon S3, without requiring internet access. This allows secure access to S3 from an EC2 instance within the same VPC, reducing latency and improving security. VPN connections and NAT gateways do not eliminate internet traffic, and an internet gateway would expose the VPC to the public internet.
