A company is moving multiple applications to a single AWS account. The company wants to monitor the AWS Cloud costs incurred by each application.
What can the company do to meet this requirement?
Set up invoiced billing.
Use AWS Artifact.
Set budgets in Cost Explorer.
Create cost allocation tags.
Answer is Create cost allocation tags.
To meet the requirement of monitoring the AWS Cloud costs incurred by each application, the company can create cost allocation tags.
Cost allocation tags allow the company to categorize resources in the AWS environment with metadata that reflects the organization's structure and needs. Each tag consists of a key-value pair that can be associated with AWS resources such as EC2 instances, EBS volumes, and RDS instances.
By applying cost allocation tags to AWS resources, the company can gain a better understanding of which resources are used by which application, and monitor the costs of each application in Cost Explorer. The company can also use the tags to filter and group the cost and usage data in reports and create custom cost allocation reports.

S3 Standard
S3 One Zone-Infrequent Access (S3 One Zone-IA)
S3 Standard-Infrequent Access (S3 Standard-IA)
S3 Glacier
Answer is S3 Standard-Infrequent Access (S3 Standard-IA)
The S3 Standard - Infrequent Access type is used with data that is accessed less frequently, but requires fast access when needed. The S3 Standard - Infrequent Access type offers the level of high durability, high throughput, and low latency of S3 Standard, with a small storage charge per GB and recovery charge per GB. The combination of high performance and low cost makes S3 Standard - Infrequent Access the ideal choice for long-term storage, backup, and as a data store for disaster recovery archives. S3 storage classes can be configured at the object level, and a single bucket can contain objects stored in S3 Standard, S3 Smart Layers, S3 Standard - Infrequent Access, and S3 Single Zone - Infrequent Access. You can also use S3 lifecycle policies to automatically move objects between storage types without application changes.

Which cloud computing benefit does AWS demonstrate with its ability to offer lower variable costs as a result of high purchase volumes?
Pay-as-you-go pricing
High availability
Global reach
Economies of scale
Answer is Economies of scale
AWS demonstrates the cloud computing benefit of economies of scale. As a cloud service provider with a large customer base and high purchase volumes, AWS is able to achieve cost efficiencies through economies of scale. This means that AWS can negotiate better pricing with hardware and software vendors, optimize resource utilization, and spread infrastructure costs across a large customer base. These cost savings are then passed on to customers in the form of lower variable costs.
One of the ways AWS offers lower variable costs is through its pay-as-you-go pricing model. With this model, customers only pay for the resources they consume on an as-needed basis, without any upfront or long-term commitments. This allows customers to scale their usage up or down based on demand and only pay for what they actually use.
Which of the following are economic advantages of the AWS Cloud? (Choose two.)
Increased workforce productivity
Decreased need to encrypt user data
Manual compliance audits
Simplified total cost of ownership (TCO) accounting
Faster product launches
Answers are;
D. Simplified total cost of ownership (TCO) accounting
E. Faster product launches
D. Simplified total cost of ownership (TCO) accounting: With AWS Cloud, customers pay only for the computing resources they use, and the cost is based on a pay-as-you-go model. This eliminates the need for large upfront capital expenses and helps in simplified TCO accounting.
E. Faster product launches: AWS Cloud provides a variety of tools and services that help in quickly developing, testing, and deploying applications. This enables faster time-to-market and reduces the cost of product launches.
Option A, Increased workforce productivity, is not an economic advantage of the AWS Cloud, as it does not directly translate to cost savings or revenue generation. Option B, Decreased need to encrypt user data, is incorrect, as data encryption is always necessary for security purposes and is not affected by the choice of cloud provider. Option C, Manual compliance audits, is also incorrect, as AWS provides a variety of compliance and security certifications, which can save time and resources needed for manual audits.
