Question 3

A company operates five separate AWS accounts for different business units. The finance team wants to aggregate the usage across all accounts to benefit from volume pricing discounts and to receive a single monthly bill. The company does not need to centrally manage permissions or apply service control policies at this time. Which AWS feature should the company use to meet these requirements?

Accepted Answer

Consolidated Billing through AWS Organizations. AWS Organizations provides Consolidated Billing, which allows a company to aggregate usage across multiple AWS accounts into a single monthly bill. This enables the finance team to benefit from volume pricing discounts because AWS combines usage across all accounts, potentially lowering the overall cost tier. The requirement does not include centralized permission management or service control policies, so the basic Consolidated Billing feature of AWS Organizations is sufficient.

Question 7

Which AWS pricing concept means you pay a lower per-unit price when you use more of a service, such as S3 charging less per GB as storage volume increases?

Accepted Answer

Tiered pricing (volume discounts). B is correct because tiered pricing (volume discounts) is the AWS pricing model where the per-unit cost decreases as usage increases. For example, Amazon S3 charges a lower per-GB rate for larger storage volumes, such as $0.023 per GB for the first 50 TB and $0.022 per GB for the next 450 TB, directly reflecting volume-based discounts.

Question 9

A company wants to migrate 50 virtual machines from their on-premises data centre to AWS as quickly as possible to reduce data centre costs. They plan to move the VMs without making any changes to the applications. Which cloud migration strategy does this represent?

Accepted Answer

Rehost. (Rehost) is correct because the company is migrating 50 virtual machines to AWS without making any changes to the applications, which is the defining characteristic of a 'lift and shift' migration. This strategy involves moving the VMs as-is, typically using AWS Server Migration Service (SMS) or AWS Application Migration Service (AWS MGN), to quickly reduce on-premises data center costs without application refactoring.

Answer

Refactor

Answer

Replatform

Answer

Retire

Question 10

A company uses AWS Organizations. The management account receives the consolidated bill. Which statement about Reserved Instance discount sharing in AWS Organizations is correct?

Accepted Answer

RI discounts are automatically shared across all member accounts in the organization. In AWS Organizations, Reserved Instance (RI) discounts are automatically shared across all accounts in the organization, provided the accounts are under the same consolidated billing family and the RIs are in the same AWS region. This means that if one member account purchases an RI, the hourly cost benefit can apply to qualifying usage from any other account in the organization, reducing the overall bill. The management account receives the consolidated bill and can see the aggregated savings, but no explicit sharing configuration is required.

Answer

Reserved Instance discounts only apply to the account that purchased the RI

Answer

RI discounts are only shared if the management account explicitly enables sharing for each RI

Answer

RI discounts cannot be shared across accounts even in an Organization

Question 11

A company currently runs its infrastructure in a colocation data center. The CIO wants to estimate the total cost of ownership (TCO) of migrating the existing workload to AWS, compared to continuing with the on-premises solution. The company has detailed data on current server specifications, power, cooling, and labor costs. Which AWS tool should the company use to perform this analysis?

Accepted Answer

AWS Total Cost of Ownership (TCO) Calculator. The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running infrastructure on-premises versus on AWS. It allows you to input detailed data on server specifications, power, cooling, and labor costs to generate a side-by-side TCO comparison, which directly meets the CIO's requirement.

Question 12

A company is migrating an on-premises application to AWS. The application will run on Amazon EC2 instances and use an Amazon RDS for MySQL database. The security team needs to understand which security controls remain the company's responsibility after the migration. Under the AWS Shared Responsibility Model, which of the following is the customer's responsibility?

Accepted Answer

Patching the guest operating system on the Amazon EC2 instances.. Under the AWS Shared Responsibility Model, the customer is responsible for patching the guest operating system on Amazon EC2 instances because EC2 is an Infrastructure as a Service (IaaS) offering where AWS manages the hypervisor and physical infrastructure, but the customer has full control over the OS, applications, and configurations. In contrast, for Amazon RDS, AWS handles patching of the database engine (e.g., MySQL) and the underlying OS, making option A AWS's responsibility. Physical security at AWS data centers is always AWS's responsibility, not the customer's.

Answer

Patching the MySQL database engine for the Amazon RDS instance.

Answer

Providing physical security at the AWS data center facilities.

Answer

Replacing failed network switches in the AWS global network.

Question 13

A security team needs to demonstrate to auditors that no AWS infrastructure has been modified between two audit periods. Which AWS service provides a continuous record of configuration changes with before-and-after state for all resources?

Accepted Answer

AWS Config. AWS Config is the correct service because it continuously records configuration changes to AWS resources and provides a detailed history of each change, including the before-and-after state. This allows the security team to demonstrate to auditors that no infrastructure modifications occurred between two audit periods by reviewing the configuration timeline and compliance snapshots.
