A stakeholder is considering AWS Budgets because a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold. What is the MOST relevant capability or benefit?
- Support rule-based business cost groupings
- Track spending or usage against defined budget thresholds
- Attribute cloud spending to business units through approved resource labels
- Support detailed cost and consumption data
Explanation
Correct Answer
B:Use AWS Budgets to track spending or usage against defined budget thresholds. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor. The stated need is specifically a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold.
Incorrect Answers
A:This outcome fits Cost Categories: Cost Categories organizes cost and usage data into custom business categories using defined rules. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.
C:This outcome fits Cost allocation tags: Cost allocation tags help group eligible charges by tagged resources after activation and appropriate billing data collection. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.
D:This outcome fits AWS Cost and Usage Report: Cost and Usage Reports provide detailed charge records suitable for custom analysis rather than just high-level charts. The stakeholder requires the more specific capability provided by AWS Budgets, not that separate benefit.

It does not explain the particular role of Amazon EKS; EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs.
Question 152
A fraud team needs to query relationships and connections among entities. Which AWS service or cloud concept is the MOST direct match for this need?
- Amazon RDS
- AWS Database Migration Service
- Amazon ElastiCache
- Amazon Neptune
Explanation
Correct Answer
D:Amazon Neptune fits the need because neptune supports graph data models for workloads centered on relationships among connected entities. The relevant capability or responsibility is: Use Amazon Neptune for graph-oriented data relationships.
Incorrect Answers
A:Amazon RDS relational database is associated with a different use case: a web application needs a managed relational database that supports SQL queries and transactions. RDS manages selected database infrastructure work for relational workloads, while users still control database schema and access. The question instead focuses on a fraud team needs to query relationships and connections among entities; Amazon Neptune is the more direct match.
B:AWS Database Migration Service is associated with a different use case: an enterprise needs help migrating data from a supported existing database to another endpoint. Database Migration Service helps migrate or replicate supported databases; it is not itself an application database engine. The question instead focuses on a fraud team needs to query relationships and connections among entities; Amazon Neptune is the more direct match.
C:Amazon ElastiCache is associated with a different use case: a shopping service needs fast in-memory access to frequently requested session information. ElastiCache reduces repeated backend reads by keeping appropriate data in memory for fast access. The question instead focuses on a fraud team needs to query relationships and connections among entities; Amazon Neptune is the more direct match.

- Let eligible costs rise and fall with actual resource consumption
- Reduce repetitive administrative work through consistent automation
- Evaluate use of qualifying existing software licenses subject to vendor and AWS terms
Explanation
Correct Answer
D:Evaluate use of qualifying existing software licenses subject to vendor and AWS terms. BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied. The stated need is specifically a company has eligible existing software licenses that might be usable on a cloud host.
Incorrect Answers
A:This outcome fits Economies of scale: Large cloud providers spread infrastructure costs across many customers and workloads. The stakeholder requires the more specific capability provided by Bring Your Own License, not that separate benefit.
B:This outcome fits Variable costs: Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The stakeholder requires the more specific capability provided by Bring Your Own License, not that separate benefit.
C:This outcome fits Automation savings: Automation can reduce manual effort and mistakes while making temporary resources easier to retire. The stakeholder requires the more specific capability provided by Bring Your Own License, not that separate benefit.
Question 157
An organization must transfer a very large volume of data from a remote site with insufficient network bandwidth. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS Snow Family
- Relocating a workload
- AWS Database Migration Service
- Replatforming migration
Explanation
Correct Answer
A:AWS Snow Family fits the need because aWS Snow devices support moving large datasets when transferring everything over a network is slow or constrained. The relevant capability or responsibility is: Use physical AWS data transfer devices where online transfer is impractical.
Incorrect Answers
B:Relocating a workload is associated with a different use case: a company can move a supported virtualized environment to AWS while maintaining its familiar virtualization stack. Relocating retains much of the underlying virtualization model while shifting where it runs. The question instead focuses on an organization must transfer a very large volume of data from a remote site with insufficient network bandwidth; AWS Snow Family is the more direct match.
C:AWS Database Migration Service is associated with a different use case: a company wants to transfer database content to AWS while limiting downtime. AWS DMS can transfer data and support change data capture for applicable database migration scenarios. The question instead focuses on an organization must transfer a very large volume of data from a remote site with insufficient network bandwidth; AWS Snow Family is the more direct match.
D:Replatforming migration is associated with a different use case: a company moves an application to AWS and also adopts a managed database without rebuilding its business logic. Replatforming adjusts selected supporting components to gain cloud benefits without a full application rewrite. The question instead focuses on an organization must transfer a very large volume of data from a remote site with insufficient network bandwidth; AWS Snow Family is the more direct match.
Question 158
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: call service APIs from application code?
- Hybrid cloud deployment
- AWS SDKs
- AWS Outposts
- AWS service APIs
Explanation
Correct Answer
B:AWS SDKs directly addresses this outcome. AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS. A common relevant example is: a developer wants a Java application to interact with AWS services using language libraries.
Incorrect Answers
A:Hybrid cloud deployment instead focuses on a different requirement, such as a bank must keep some applications on its own premises while using AWS for other services. A hybrid deployment model uses both on-premises environments and cloud infrastructure rather than moving every workload immediately. It is not the primary match for the requirement described here: call service APIs from application code.
C:AWS Outposts instead focuses on a different requirement, such as a manufacturer needs AWS-managed hardware and selected cloud services in its own facility. Outposts extends supported AWS infrastructure and services to customer locations where local processing or data needs apply. It is not the primary match for the requirement described here: call service APIs from application code.
D:AWS service APIs instead focuses on a different requirement, such as a system needs a programmatic interface to request and manage AWS resources. AWS APIs enable programmatic service access; management consoles and SDKs are other ways to use such capabilities. It is not the primary match for the requirement described here: call service APIs from application code.
Question 159
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: account for service- and route-dependent data transfer pricing?
- EC2 Reserved Instances
- On-Demand Capacity Reservations
- AWS data transfer charges
- EC2 On-Demand Instances
Explanation
Correct Answer
C:AWS data transfer charges directly addresses this outcome. Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path. A common relevant example is: a company compares incoming internet traffic with traffic sent from AWS to external users.
Incorrect Answers
A:Reserved Instances instead focuses on a different requirement, such as an enterprise runs a predictable EC2 workload and can make a qualifying commitment. Reserved Instances offer pricing benefits for qualifying EC2 usage with a term commitment and specified attributes. It is not the primary match for the requirement described here: account for service- and route-dependent data transfer pricing.
B:On-Demand Capacity Reservations instead focuses on a different requirement, such as a business needs assurance that EC2 capacity will be available in a chosen Availability Zone for a planned event. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction. It is not the primary match for the requirement described here: account for service- and route-dependent data transfer pricing.
D:On-Demand EC2 pricing instead focuses on a different requirement, such as a company needs compute capacity for a short unpredictable project and does not want a long commitment. On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments. It is not the primary match for the requirement described here: account for service- and route-dependent data transfer pricing.
Question 160
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates Amazon ECS, rather than a different AWS concept?
- An analytics node needs high local disk throughput for temporary data processing
- A business runs an application that needs very large in-memory data structures
- A website needs inbound requests distributed among several healthy application targets
- An application team needs AWS-native orchestration of container workloads
Explanation
Correct Answer
D:The decisive requirement is: Use Amazon Elastic Container Service to manage containerized applications. This is the role of Amazon ECS. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
Incorrect Answers
A:This describes a scenario for Storage-optimized EC2: choose an EC2 storage-optimized instance family where local storage performance is central. Storage-optimized instance families are designed for high local storage I/O and throughput needs. It is not the most direct example of Amazon ECS.
B:This describes a scenario for Memory-optimized EC2: choose an EC2 memory-optimized instance family. Memory-optimized instances emphasize memory capacity relative to processing, fitting memory-intensive workloads. It is not the most direct example of Amazon ECS.
C:This describes a scenario for Elastic Load Balancing: use Elastic Load Balancing to distribute incoming workload traffic. Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance. It is not the most direct example of Amazon ECS.
