Activating tags for detailed billing lets the company label resources with specific team identifiers, and, once these tags are activated, they help break down expenditure in cost reports according to the tagged labels. 'Naming conventions' provide a way to identify resources but don't enable cost categorization in billing reports. 'Budgets' help in setting spending limits but don't detail cost allocation. 'Configuration Compliance' is not related to cost allocation, and 'Multiple accounts' would separate costs but may be overly complex and do not exploit the full capabilities of cost allocation tags.

The correct answer is AWS Artifact because it is specifically designed to provide users with security and compliance documents, such as audit reports, that inform them about AWS compliance with global regulations, which is critical for customers managing cloud resources in different regulatory environments.

AWS Glacier Deep Archive is an extremely low-cost storage service for data archiving and long-term backup. It is designed for data that is accessed very infrequently but still requires long-term retention. Data retrieval times of 12 hours or more are acceptable for this service, aligning well with the company's needs where immediate access is not crucial. The other options provided do not offer the same cost efficiency for the described archival use case.

Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is designed for data that is accessed less frequently, but requires rapid access when needed. It offers a lower storage price compared to Amazon S3 Standard, making it cost-effective for infrequently accessed data. On the other hand, S3 One Zone-IA is for infrequently accessed data that doesn't require the multiple Availability Zone data resilience, S3 Glacier is for long-term archival storage, and S3 Intelligent-Tiering automatically moves objects between different tiers based on changing access patterns.

Answer 'D' is correct because it encompasses the principles of high availability (multiple Availability Zones), elasticity (automatically adding resources to meet demand), and agility (quick deployment of resources). While 'A' refers to elasticity and 'B' to high availability, neither 'A' nor 'B' incorporates agility. Answer 'C' does not specifically address any of the three advantages.

The correct resource for finding comprehensive guides and architecture design patterns is AWS Prescriptive Guidance. It offers structured recommendations and best practices for cloud application development. Meanwhile, the AWS Pricing Calculator focuses on estimating costs for AWS services, not providing architectural guidance. The whitepapers are in-depth technical documents but do not offer the same interactive and structured recommendations as Prescriptive Guidance. Lastly, the Management Console is an interface for managing AWS services, not a source for architectural design patterns and guides.

Amazon GuardDuty is the correct answer because it is specifically designed as a threat detection service that continuously monitors for malicious or unauthorized activities. Amazon GuardDuty applies machine learning and anomaly detection to identify unexpected and potentially unauthorized or malicious activity within your cloud environment. AWS Security Hub provides a comprehensive view of security alerts and security posture across your accounts. Amazon Inspector is focused on the security assessment of applications running on the cloud, whereas AWS Shield specifically provides protection against DDoS attacks.

The Billing and Cost Management Dashboard is the centralized tool for customers to access detailed billing statements, visualize past usage and costs, manage payment methods, and explore cost management features like budgets and alerts. While other resources such as general documentation or support services, as well as pricing estimations for future use, may offer assistance, the Dashboard is specifically tailored to give comprehensive billing insights and is the most direct resource for current billing information and queries.

To accommodate both predictable baseline usage and intermittent spikes, the best approach is to combine Reserved Instances (RIs) for the baseline capacity with On-Demand Instances to handle peak loads. RIs offer a discounted hourly rate and capacity reservation, making them suitable for the steady baseline workload, while On-Demand Instances provide the flexibility to scale up without any upfront commitment, which is ideal for handling unpredictable spikes. Savings Plans require a commitment to a specific amount of usage (measured in $/hour) over 1 or 3 years and could lead to overcommitment during non-peak times. Meanwhile, Spot Instances offer the highest discounts but can be terminated by AWS when the spot price exceeds the bid price, which risks stability during demand spikes.

The transfer of data across different geographical locations, or regions, incurs additional costs because it involves the use of extensive networking infrastructure to facilitate the transfer. On the other hand, transferring data within the same region or uploading to cloud storage from the internet generally does not incur extra charges.

This statement is true. Reserved Instances offer a significant discount over On-Demand Instance pricing, which can be up to 75% depending on the term and payment options. Moreover, when a Reserved Instance is specified for a particular Availability Zone, AWS reserves capacity for that instance, ensuring that the user can launch that instance when needed in the chosen Availability Zone. Other options like Spot Instances can offer even more significant savings but do not guarantee availability, while On-Demand Instances guarantee availability but at higher costs without upfront commitments.

The correct answer is AWS CloudTrail. It’s designed to capture and record all actions taken within an environment, like user accesses and API activities, which is crucial for auditing and compliance purposes. While Amazon CloudWatch provides monitoring and logging capabilities, it is not primarily used for recording API call history. AWS Security Hub focuses on security checks and consolidations of findings from various services but does not specifically track user actions or API calls. Amazon Inspector offers automated security assessment services and does not deal with logging and tracking of all interactions within an environment. Therefore, CloudTrail is the best fit for the requirement.

The service that fits this requirement is Security Hub because it integrates with various data sources, such as other security services and partner products, to provide a centralized view and management of security alerts and compliance status. It automatically aggregates and prioritizes findings to help focus on the highest risks. In contrast, Shield specializes in DDoS protection, Inspector offers automated vulnerability assessments for applications, and CloudWatch primarily provides monitoring for operational metrics rather than a comprehensive security analysis.

Using Snowball devices is the correct answer because this approach is designed for moving huge amounts of data without depending on the available bandwidth. It's particularly cost-effective for transferring data that spans terabytes to petabytes. Snowball also provides encryption, which secures the data during physical transit. This strategy is suitable for shifting infrequently accessed, large archival data when bandwidth is limited. In contrast, other options mentioned would either rely heavily on internet connectivity or are designed for more continuous data transfer needs rather than a one-off, bulk data migration.

The correct choice is the service that allows developers to write and deploy code that executes in response to events, automatically handling the infrastructure management. This service is designed to handle sudden increases in usage, making it highly suitable for applications with unpredictable workloads. In contrast, the others mentioned are either compute instances requiring management, managed services for container orchestration, or containers as a service which do not offload the management of the orchestration layer.
