Question 300
A project manager compares IAM users with other AWS concepts while considering this need: an organization must represent an individual with long-term credentials in one AWS account. Which pairing assigns the responsibilities or benefits correctly?
- IAM users: manage shared user permissions; IAM groups: meet this requirement: an organization must represent an individual with long-term credentials in one AWS account
- IAM users: require MFA for eligible AWS sign-in identities; Multi-factor authentication: meet this requirement: an organization must represent an individual with long-term credentials in one AWS account
- IAM users: secure the root identity with MFA and avoid routine root use; Root user protection: meet this requirement: an organization must represent an individual with long-term credentials in one AWS account
- IAM users: meet this requirement: an organization must represent an individual with long-term credentials in one AWS account; Multi-factor authentication: require MFA for eligible AWS sign-in identities
Explanation
Correct Answer
D:The first pairing identifies IAM users with its actual role: use an IAM user where that identity model is specifically required. IAM users are identities within an account; organizations generally favor federation and short-lived credentials where suitable. The comparison is valid because Multi-factor authentication instead addresses require MFA for eligible AWS sign-in identities.
Incorrect Answers
A:The roles are swapped. IAM groups is associated with use an IAM group to manage shared user permissions; IAM users instead has the role: Use an IAM user where that identity model is specifically required. IAM users are identities within an account; organizations generally favor federation and short-lived credentials where suitable.
B:The roles are swapped. Multi-factor authentication is associated with require MFA for eligible AWS sign-in identities; IAM users instead has the role: Use an IAM user where that identity model is specifically required. IAM users are identities within an account; organizations generally favor federation and short-lived credentials where suitable.
C:The roles are swapped. Root user protection is associated with secure the root identity with MFA and avoid routine root use; IAM users instead has the role: Use an IAM user where that identity model is specifically required. IAM users are identities within an account; organizations generally favor federation and short-lived credentials where suitable.
Question 301
A stakeholder is considering Rightsizing because a monthly review finds development servers consume little of their allocated CPU and memory. What is the MOST relevant capability or benefit?
- Choose resource sizes appropriate for actual workload utilization
- Benefit from aggregate cloud-provider scale and procurement efficiency
- Classify upfront infrastructure equipment purchases as capital spending
- Use a service price that bundles eligible software licensing
Explanation
Correct Answer
A:Choose resource sizes appropriate for actual workload utilization. Rightsizing replaces persistently oversized resources with suitable capacities to improve cost efficiency. The stated need is specifically a monthly review finds development servers consume little of their allocated CPU and memory.
Incorrect Answers
B: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 Rightsizing, not that separate benefit.
C:This outcome fits Capital expenditure: Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption. The stakeholder requires the more specific capability provided by Rightsizing, not that separate benefit.
D:This outcome fits License-included pricing: License-included pricing is distinct from providing a separately acquired customer license under BYOL. The stakeholder requires the more specific capability provided by Rightsizing, not that separate benefit.
Question 302
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates AWS Transit Gateway, rather than a different AWS concept?
- An enterprise wants a dedicated private network connection between its premises and AWS
- A company needs a central networking hub connecting multiple VPCs and applicable on-premises networks
- A team wants a logically isolated network environment for its AWS compute resources
- A VPC owner needs network traffic rules at the subnet boundary and wants stateless filtering
Explanation
Correct Answer
B:The decisive requirement is: Use AWS Transit Gateway to simplify multi-network connectivity. This is the role of AWS Transit Gateway. Transit Gateway acts as a regional routing hub for supported VPC and network attachments.
Incorrect Answers
A:This describes a scenario for AWS Direct Connect: use AWS Direct Connect for dedicated network connectivity to AWS. Direct Connect provides private physical network connectivity through supported locations; encryption is a separate consideration. It is not the most direct example of AWS Transit Gateway.
C:This describes a scenario for Amazon VPC: use Amazon Virtual Private Cloud for customer-defined virtual networking. A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity. It is not the most direct example of AWS Transit Gateway.
D:This describes a scenario for Network ACLs: use network access control lists for subnet-level traffic rules. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior. It is not the most direct example of AWS Transit Gateway.
Question 303
A project manager compares Cost Optimization pillar with other AWS concepts while considering this need: a department wants to eliminate idle spending and understand the cost of delivering business value. Which pairing assigns the responsibilities or benefits correctly?
- Cost Optimization pillar: revisit architecture decisions as requirements and capabilities change; Design for expected change: avoid unnecessary expense while delivering required outcomes
- Cost Optimization pillar: represent infrastructure configuration declaratively and apply repeatable changes; Infrastructure changes as code: avoid unnecessary expense while delivering required outcomes
- Cost Optimization pillar: avoid unnecessary expense while delivering required outcomes; Infrastructure changes as code: represent infrastructure configuration declaratively and apply repeatable changes
- Cost Optimization pillar: continuously improve operations and operational procedures; Operational Excellence pillar: avoid unnecessary expense while delivering required outcomes
Explanation
Correct Answer
C:The first pairing identifies Cost Optimization pillar with its actual role: avoid unnecessary expense while delivering required outcomes. Cost Optimization includes understanding expenditure, selecting cost-effective resources, and managing demand and supply. The comparison is valid because Infrastructure changes as code instead addresses represent infrastructure configuration declaratively and apply repeatable changes.
Incorrect Answers

- Amazon EKS
- AWS Fargate
- Compute-optimized EC2
- AWS Lambda
Explanation
Correct Answer
A:Amazon EKS fits the need because eKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs. The relevant capability or responsibility is: Use Amazon Elastic Kubernetes Service for AWS-hosted Kubernetes orchestration.
Incorrect Answers
B:AWS Fargate is associated with a different use case: a development team wants to run supported containers without managing the underlying EC2 host fleet. Fargate supplies compute capacity for supported container tasks without customers administering container hosts. The question instead focuses on an organization wants managed Kubernetes control-plane capabilities for containerized workloads; Amazon EKS is the more direct match.
C:Compute-optimized EC2 is associated with a different use case: a simulation workload spends most of its time performing CPU-intensive numerical calculations. Compute-optimized instances provide a high ratio of compute performance for suitable CPU-bound applications. The question instead focuses on an organization wants managed Kubernetes control-plane capabilities for containerized workloads; Amazon EKS is the more direct match.
D:AWS Lambda is associated with a different use case: an online form should run short application code only when events occur without managing servers. Lambda executes event-triggered code without the customer managing underlying servers, subject to service limits. The question instead focuses on an organization wants managed Kubernetes control-plane capabilities for containerized workloads; Amazon EKS is the more direct match.
Question 306

Explanation
Correct Answer
D:Amazon SES directly addresses this outcome. SES provides email sending and related features for business application communications. A common relevant example is: a company must send transactional confirmation emails from its application.
Incorrect Answers
A:AWS Step Functions instead focuses on a different requirement, such as a business process needs a coordinated sequence of several AWS service tasks with branching states. Step Functions models stateful application workflows and service coordination rather than storing the business records. It is not the primary match for the requirement described here: support application email delivery.
B:Amazon Connect instead focuses on a different requirement, such as a company wants a cloud-based customer contact center with voice and contact workflows. Amazon Connect offers contact-center services, distinct from a general-purpose messaging queue. It is not the primary match for the requirement described here: support application email delivery.
C:Amazon SQS instead focuses on a different requirement, such as an order processing system wants queued messages so producers and workers do not need to run at the same speed. SQS buffers work items for asynchronous consumption, unlike a publish-subscribe notification fan-out service. It is not the primary match for the requirement described here: support application email delivery.
