Question 1110
A project manager compares Amazon ECS with other AWS concepts while considering this need: an application team needs AWS-native orchestration of container workloads. Which pairing assigns the responsibilities or benefits correctly?
- Amazon ECS: meet this requirement: an analytics node needs high local disk throughput for temporary data processing; Storage-optimized EC2: manage containerized applications
- Amazon ECS: manage containerized applications; Storage-optimized EC2: meet this requirement: an analytics node needs high local disk throughput for temporary data processing
- Amazon ECS: distribute inbound traffic among healthy application targets; Elastic Load Balancing: manage containerized applications
- Amazon ECS: meet this requirement: a business runs an application that needs very large in-memory data structures; Memory-optimized EC2: manage containerized applications
Explanation
Correct Answer
B:The first pairing identifies Amazon ECS with its actual role: use Amazon Elastic Container Service to manage containerized applications. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options. The comparison is valid because Storage-optimized EC2 instead addresses choose an EC2 storage-optimized instance family where local storage performance is central.
Incorrect Answers
A:The roles are swapped. Storage-optimized EC2 is associated with choose an EC2 storage-optimized instance family where local storage performance is central; Amazon ECS instead has the role: Use Amazon Elastic Container Service to manage containerized applications. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
C:The roles are swapped. Elastic Load Balancing is associated with use Elastic Load Balancing to distribute incoming workload traffic; Amazon ECS instead has the role: Use Amazon Elastic Container Service to manage containerized applications. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
D:The roles are swapped. Memory-optimized EC2 is associated with choose an EC2 memory-optimized instance family; Amazon ECS instead has the role: Use Amazon Elastic Container Service to manage containerized applications. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
Question 1111
A project manager compares On-Demand Capacity Reservations with other AWS concepts while considering this need: a business needs assurance that EC2 capacity will be available in a chosen Availability Zone for a planned event. Which pairing assigns the responsibilities or benefits correctly?
- On-Demand Capacity Reservations: meet this requirement: an organization needs a physical host dedicated to its account for certain licensing or compliance needs; Dedicated Hosts: reserve eligible compute capacity without necessarily purchasing a usage discount
- On-Demand Capacity Reservations: reduce eligible compute costs with a usage commitment; Savings Plans: reserve eligible compute capacity without necessarily purchasing a usage discount
- On-Demand Capacity Reservations: reserve eligible compute capacity without necessarily purchasing a usage discount; AWS data transfer charges: account for service- and route-dependent data transfer pricing
- On-Demand Capacity Reservations: account for service- and route-dependent data transfer pricing; AWS data transfer charges: reserve eligible compute capacity without necessarily purchasing a usage discount
Explanation
Correct Answer
C:The first pairing identifies On-Demand Capacity Reservations with its actual role: reserve eligible compute capacity without necessarily purchasing a usage discount. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction. The comparison is valid because AWS data transfer charges instead addresses account for service- and route-dependent data transfer pricing.
Incorrect Answers
A:The roles are swapped. Dedicated Hosts is associated with use Dedicated Hosts when eligible licensing requires host visibility and control; On-Demand Capacity Reservations instead has the role: Reserve eligible compute capacity without necessarily purchasing a usage discount. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.
B:The roles are swapped. Savings Plans is associated with use Savings Plans to reduce eligible compute costs with a usage commitment; On-Demand Capacity Reservations instead has the role: Reserve eligible compute capacity without necessarily purchasing a usage discount. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.
D:The roles are swapped. AWS data transfer charges is associated with account for service- and route-dependent data transfer pricing; On-Demand Capacity Reservations instead has the role: Reserve eligible compute capacity without necessarily purchasing a usage discount. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.
Question 1112
A team prefers a cloud software offering whose price includes the relevant software license. Which AWS service or cloud concept is the MOST direct match for this need?
- Idle resource spending
- Rightsizing
- Capital expenditure
- License-included pricing
Explanation
Correct Answer
D:License-included pricing fits the need because license-included pricing is distinct from providing a separately acquired customer license under BYOL. The relevant capability or responsibility is: Use a service price that bundles eligible software licensing.
Incorrect Answers
A:Idle resource spending is associated with a different use case: an internal testing account leaves unused compute instances running every weekend. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending. The question instead focuses on a team prefers a cloud software offering whose price includes the relevant software license; License-included pricing is the more direct match.
B:Rightsizing is associated with a different use case: a monthly review finds development servers consume little of their allocated CPU and memory. Rightsizing replaces persistently oversized resources with suitable capacities to improve cost efficiency. The question instead focuses on a team prefers a cloud software offering whose price includes the relevant software license; License-included pricing is the more direct match.
C:Capital expenditure is associated with a different use case: a company buys servers and pays the purchase cost before those servers are used. Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption. The question instead focuses on a team prefers a cloud software offering whose price includes the relevant software license; License-included pricing is the more direct match.
Question 1113
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: use a service price that bundles eligible software licensing?
- License-included pricing
- Rightsizing
- Economies of scale
- Idle resource spending
Explanation
Correct Answer
A:License-included pricing directly addresses this outcome. License-included pricing is distinct from providing a separately acquired customer license under BYOL. A common relevant example is: a team prefers a cloud software offering whose price includes the relevant software license.
Incorrect Answers
B:Rightsizing instead focuses on a different requirement, such as a monthly review finds development servers consume little of their allocated CPU and memory. Rightsizing replaces persistently oversized resources with suitable capacities to improve cost efficiency. It is not the primary match for the requirement described here: use a service price that bundles eligible software licensing.
C:Economies of scale instead focuses on a different requirement, such as a small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself. Large cloud providers spread infrastructure costs across many customers and workloads. It is not the primary match for the requirement described here: use a service price that bundles eligible software licensing.
D:Idle resource spending instead focuses on a different requirement, such as an internal testing account leaves unused compute instances running every weekend. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending. It is not the primary match for the requirement described here: use a service price that bundles eligible software licensing.
Question 1114
A stakeholder is considering AWS data transfer charges because a company compares incoming internet traffic with traffic sent from AWS to external users. What is the MOST relevant capability or benefit?
- Trade some flexibility for eligible discounted capacity or spending commitments
- Account for service- and route-dependent data transfer pricing
- Support eligible long-running instance usage discounts
- Compare storage duration, retrieval charges and access characteristics of S3 classes
Explanation
Correct Answer
B:Account for service- and route-dependent data transfer pricing. Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path. The stated need is specifically a company compares incoming internet traffic with traffic sent from AWS to external users.
Incorrect Answers
A:This outcome fits Compute commitment flexibility: Commitment options can lower qualifying compute costs, but suitability depends on sustained predictable usage and terms. The stakeholder requires the more specific capability provided by AWS data transfer charges, not that separate benefit.
C:This outcome fits Reserved Instances: Reserved Instances offer pricing benefits for qualifying EC2 usage with a term commitment and specified attributes. The stakeholder requires the more specific capability provided by AWS data transfer charges, not that separate benefit.
D:This outcome fits S3 storage-class pricing: S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost. The stakeholder requires the more specific capability provided by AWS data transfer charges, not that separate benefit.
Question 1115
A project manager compares Amazon CloudFront with other AWS concepts while considering this need: users worldwide download the same publicly available product images from an origin. Which pairing assigns the responsibilities or benefits correctly?
- Amazon CloudFront: support global network traffic entry and endpoint routing; AWS Global Accelerator: deliver cached web content nearer to globally distributed users
- Amazon CloudFront: distribute components across isolated locations inside one geographic Region; Availability Zone: deliver cached web content nearer to globally distributed users
- Amazon CloudFront: deliver cached web content nearer to globally distributed users; AWS Region: select a geographic cloud infrastructure location
- Amazon CloudFront: select a geographic cloud infrastructure location; AWS Region: deliver cached web content nearer to globally distributed users
Explanation
Correct Answer
C:The first pairing identifies Amazon CloudFront with its actual role: deliver cacheable content through Amazon CloudFront edge locations. CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers. The comparison is valid because AWS Region instead addresses choose an AWS Region to select a geographic cloud infrastructure location.
Incorrect Answers
A:The roles are swapped. AWS Global Accelerator is associated with use AWS Global Accelerator for global network traffic entry and endpoint routing; Amazon CloudFront instead has the role: Deliver cacheable content through Amazon CloudFront edge locations. CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers.
B:The roles are swapped. Availability Zone is associated with distribute components across Availability Zones for fault isolation; Amazon CloudFront instead has the role: Deliver cacheable content through Amazon CloudFront edge locations. CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers.
D:The roles are swapped. AWS Region is associated with choose an AWS Region to select a geographic cloud infrastructure location; Amazon CloudFront instead has the role: Deliver cacheable content through Amazon CloudFront edge locations. CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers.
Question 1116
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates AWS Billing console, rather than a different AWS concept?
- An organization needs granular line-item records of AWS charges for internal analytics
- A company wants a centralized bill and eligible aggregated charges from multiple AWS accounts
- A finance analyst wants to see past AWS spending trends by service and forecast likely future cost
- An account administrator wants to inspect current billing information and payment-related account details
Explanation
Correct Answer
D:The decisive requirement is: Use AWS Billing and Cost Management console for account billing views. This is the role of AWS Billing console. The billing console presents charges and payment information; budget alerts and granular reports are separate tools.
Incorrect Answers
A:This describes a scenario for AWS Cost and Usage Report: use AWS Cost and Usage Reports for detailed cost and consumption data. Cost and Usage Reports provide detailed charge records suitable for custom analysis rather than just high-level charts. It is not the most direct example of AWS Billing console.
B:This describes a scenario for Consolidated billing: use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. It is not the most direct example of AWS Billing console.
C:This describes a scenario for AWS Cost Explorer: use AWS Cost Explorer to explore and forecast AWS cost and usage. Cost Explorer offers interactive cost analysis and forecasting over supported billing data. It is not the most direct example of AWS Billing console.
Question 1117
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates Cost Categories, rather than a different AWS concept?
- Finance needs to group charges from several services into business-defined departments or cost centers
- A project manager wants an alert when forecast monthly cloud spending will exceed a set threshold
- An account administrator wants to inspect current billing information and payment-related account details
- A company wants a centralized bill and eligible aggregated charges from multiple AWS accounts
Explanation
Correct Answer
A:The decisive requirement is: Use AWS Cost Categories for rule-based business cost groupings. This is the role of Cost Categories. Cost Categories organizes cost and usage data into custom business categories using defined rules.
Incorrect Answers
B:This describes a scenario for AWS Budgets: 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. It is not the most direct example of Cost Categories.
C:This describes a scenario for AWS Billing console: use AWS Billing and Cost Management console for account billing views. The billing console presents charges and payment information; budget alerts and granular reports are separate tools. It is not the most direct example of Cost Categories.
D:This describes a scenario for Consolidated billing: use AWS Organizations consolidated billing across eligible member accounts. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. It is not the most direct example of Cost Categories.
Question 1118
A learner is explaining Pay-as-you-go consumption to colleagues facing this situation: a seasonal nonprofit wants computing only during a two-week annual campaign. Which explanation is MOST accurate?
- AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.
- Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption.
- Managed AWS offerings take on selected provisioning and maintenance tasks while customers remain responsible for their data and access policies.
- Durability describes the likelihood that stored data remains intact; it is different from immediate service accessibility.
Explanation
Correct Answer
B:Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption. The explanation directly connects Pay-as-you-go consumption to pay for consumed services instead of buying hardware for the annual peak for the stated requirement.
Incorrect Answers
A:This statement is true of Global reach, which addresses a software provider wants to serve customers from multiple continents without building overseas data centers. It does not explain the particular role of Pay-as-you-go consumption; Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption.
C:This statement is true of Managed service operations, which addresses an analytics team prefers a managed database rather than operating its own database host. It does not explain the particular role of Pay-as-you-go consumption; Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption.
D:This statement is true of Storage durability, which addresses a photo service needs stored customer pictures to remain intact despite individual storage hardware failures. It does not explain the particular role of Pay-as-you-go consumption; Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption.
Question 1119
A retail site needs more EC2 instances during traffic spikes and fewer when usage falls. Which AWS service or cloud concept is the MOST direct match for this need?
- Amazon EC2
- Amazon EKS
- EC2 Auto Scaling
- Amazon ECS
Explanation
Correct Answer
C:EC2 Auto Scaling fits the need because eC2 Auto Scaling can add or remove instances based on policies to help meet capacity and availability needs. The relevant capability or responsibility is: Use Amazon EC2 Auto Scaling to adjust instance capacity based on demand.
Incorrect Answers
A:Amazon EC2 virtual servers is associated with a different use case: a software vendor needs full control of a virtual machine operating system for a legacy application. EC2 offers virtual servers with selectable instance types and customer-managed guest operating systems. The question instead focuses on a retail site needs more EC2 instances during traffic spikes and fewer when usage falls; EC2 Auto Scaling is the more direct match.
B:Amazon EKS is associated with a different use case: an organization wants managed Kubernetes control-plane capabilities for containerized workloads. EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs. The question instead focuses on a retail site needs more EC2 instances during traffic spikes and fewer when usage falls; EC2 Auto Scaling is the more direct match.
D:Amazon ECS is associated with a different use case: an application team needs AWS-native orchestration of container workloads. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options. The question instead focuses on a retail site needs more EC2 instances during traffic spikes and fewer when usage falls; EC2 Auto Scaling is the more direct match.
Question 1120
A stakeholder is considering IAM groups because a team needs to assign the same AWS permissions to several IAM users. What is the MOST relevant capability or benefit?
- Meet this requirement: an application needs controlled storage and rotation of a database password
- Provide temporary credentials to the workload
- Require MFA for eligible AWS sign-in identities
- Manage shared user permissions
Explanation
Correct Answer
D:Use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles. The stated need is specifically a team needs to assign the same AWS permissions to several IAM users.
Incorrect Answers
A:This outcome fits AWS Secrets Manager: Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
B:This outcome fits IAM roles: IAM roles can be assumed to obtain temporary security credentials and avoid embedding long-term keys in applications. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
C:This outcome fits Multi-factor authentication: MFA requires another authentication factor beyond a password and reduces risks from compromised passwords. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
