Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support account billing views?
- AWS Cost Explorer
- Cost Categories
- AWS Billing console
- Consolidated billing
Explanation
Correct Answer
C:AWS Billing console directly addresses this outcome. The billing console presents charges and payment information; budget alerts and granular reports are separate tools. A common relevant example is: an account administrator wants to inspect current billing information and payment-related account details.
Incorrect Answers
A:AWS Cost Explorer instead focuses on a different requirement, such as a finance analyst wants to see past AWS spending trends by service and forecast likely future cost. Cost Explorer offers interactive cost analysis and forecasting over supported billing data. It is not the primary match for the requirement described here: support account billing views.
B:Cost Categories instead focuses on a different requirement, such as finance needs to group charges from several services into business-defined departments or cost centers. Cost Categories organizes cost and usage data into custom business categories using defined rules. It is not the primary match for the requirement described here: support account billing views.
D:Consolidated billing instead focuses on a different requirement, such as a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. It is not the primary match for the requirement described here: support account billing views.

- Amazon Route 53
- Security groups
- AWS PrivateLink
- Amazon VPC
Explanation
Correct Answer
C:AWS PrivateLink directly addresses this outcome. PrivateLink uses VPC endpoints to access supported services over private connectivity without traversing the public internet. A common relevant example is: a customer wants private access to a supported service without exposing traffic through public IP endpoints.
Incorrect Answers
A:Amazon Route 53 instead focuses on a different requirement, such as a business needs a managed DNS service for resolving public application domain names. Route 53 supplies managed DNS records and routing policies, rather than acting as a virtual machine host. It is not the primary match for the requirement described here: support private service connectivity from a VPC.
B:Security groups instead focuses on a different requirement, such as an EC2 workload should allow only specified inbound and outbound connections at the resource level. Security groups control permitted traffic for associated resources and automatically allow response traffic to allowed flows. It is not the primary match for the requirement described here: support private service connectivity from a VPC.
D:Amazon VPC instead focuses on a different requirement, such as a team wants a logically isolated network environment for its AWS compute resources. A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity. It is not the primary match for the requirement described here: support private service connectivity from a VPC.

- Resource pooling
- High availability
- Fault tolerance
- Global reach
Explanation
Correct Answer
A:Resource pooling fits the need because cloud resource pooling supports multiple customers and workloads through provider-managed shared infrastructure with isolation controls. The relevant capability or responsibility is: Share provider-managed infrastructure while retaining logical workload isolation.
Incorrect Answers
B:High availability is associated with a different use case: a hospital booking service must remain accessible even when one hosting location becomes unavailable. High availability focuses on minimizing service interruptions through redundancy and service continuity. The question instead focuses on several departments need separate virtual workloads without each purchasing dedicated physical machines; Resource pooling is the more direct match.
C:Fault tolerance is associated with a different use case: a payment-processing workload must continue processing transactions when an individual component unexpectedly fails. Fault tolerance keeps service functioning when failures happen, often through replicated or redundant components. The question instead focuses on several departments need separate virtual workloads without each purchasing dedicated physical machines; Resource pooling is the more direct match.
D:Global reach is associated with a different use case: a software provider wants to serve customers from multiple continents without building overseas data centers. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market. The question instead focuses on several departments need separate virtual workloads without each purchasing dedicated physical machines; Resource pooling is the more direct match.

- Encryption in transit
- AWS Config
- Security logging retention
- Amazon Inspector
Explanation
Correct Answer
B:AWS Config directly addresses this outcome. AWS Config tracks supported resource configuration history and rules rather than serving as a generic application log service. A common relevant example is: an organization must inspect how an AWS resource configuration changed over time.
Incorrect Answers
A:Encryption in transit instead focuses on a different requirement, such as a company wants to protect data while it moves between clients and an online service. Encryption in transit protects communications over networks; it differs from encryption of data stored on disks. It is not the primary match for the requirement described here: track configuration changes and evaluate resource compliance over time.
C:Security logging retention instead focuses on a different requirement, such as an organization wants security logs available for internal investigations for a defined period. Collecting logs alone is insufficient unless their access, preservation and lifecycle align with organizational policy. It is not the primary match for the requirement described here: track configuration changes and evaluate resource compliance over time.
D:Amazon Inspector vulnerability findings instead focuses on a different requirement, such as an administrator wants continuous assessments of supported workloads for software vulnerabilities. Inspector identifies package and supported workload vulnerabilities; it is not a replacement for data classification. It is not the primary match for the requirement described here: track configuration changes and evaluate resource compliance over time.
Question 1079
A learner is explaining Replatforming migration to colleagues facing this situation: a company moves an application to AWS and also adopts a managed database without rebuilding its business logic. Which explanation is MOST accurate?
- Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value.
- Refactoring transforms the application architecture, rather than simply moving the existing runtime to the cloud.
- Replatforming adjusts selected supporting components to gain cloud benefits without a full application rewrite.
- AWS Application Migration Service supports continuous replication and cutover for eligible servers.
Explanation
