Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 41
Question 400
A business pays recurring usage charges for AWS resources it uses this month. Which AWS service or cloud concept is the MOST direct match for this need?
- Variable costs
- Total cost of ownership
- Automation savings
- Operating expenditure
Explanation
Correct Answer
D:Operating expenditure fits the need because variable cloud charges generally align with operating expense rather than a customer buying provider hardware. The relevant capability or responsibility is: Classify cloud usage-based service payments as operating spending.
Incorrect Answers
A:Variable costs is associated with a different use case: a retailer wants lower cloud expenses during months with fewer transactions. Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The question instead focuses on a business pays recurring usage charges for AWS resources it uses this month; Operating expenditure is the more direct match.
B:Total cost of ownership is associated with a different use case: a finance director compares AWS migration with building another private data center. Total cost of ownership considers direct and indirect costs, not only an instance hourly price. The question instead focuses on a business pays recurring usage charges for AWS resources it uses this month; Operating expenditure is the more direct match.
C:Automation savings is associated with a different use case: a department repeatedly creates and deletes temporary test environments by hand. Automation can reduce manual effort and mistakes while making temporary resources easier to retire. The question instead focuses on a business pays recurring usage charges for AWS resources it uses this month; Operating expenditure is the more direct match.
Question 401
A stakeholder is considering Amazon S3 storage class selection because an archive team needs to compare object storage costs between frequently accessed and rarely retrieved data. What is the MOST relevant capability or benefit?
- Compare storage duration, retrieval charges and access characteristics of S3 classes
- Meet this requirement: an organization needs a physical host dedicated to its account for certain licensing or compliance needs
- Support eligible long-running instance usage discounts
- Trade some flexibility for eligible discounted capacity or spending commitments
Explanation
Correct Answer
A:Compare storage duration, retrieval charges and access characteristics of S3 classes. S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost. The stated need is specifically an archive team needs to compare object storage costs between frequently accessed and rarely retrieved data.
Incorrect Answers
B:This outcome fits Dedicated Hosts: Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs. The stakeholder requires the more specific capability provided by Amazon S3 storage class selection, 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 Amazon S3 storage class selection, not that separate benefit.
D: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 Amazon S3 storage class selection, not that separate benefit.
Question 402
Within the Cloud Concepts domain, which business example MOST clearly illustrates Total cost of ownership, rather than a different AWS concept?
- A company has eligible existing software licenses that might be usable on a cloud host
- A finance director compares AWS migration with building another private data center
- A business pays recurring usage charges for AWS resources it uses this month
- An internal testing account leaves unused compute instances running every weekend
Explanation
Correct Answer
B:The decisive requirement is: Include facilities, hardware, operations, and staffing in a long-term cost comparison. This is the role of Total cost of ownership. Total cost of ownership considers direct and indirect costs, not only an instance hourly price.
Incorrect Answers
A:This describes a scenario for Bring Your Own License: 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. It is not the most direct example of Total cost of ownership.
C:This describes a scenario for Operating expenditure: classify cloud usage-based service payments as operating spending. Variable cloud charges generally align with operating expense rather than a customer buying provider hardware. It is not the most direct example of Total cost of ownership.
D:This describes a scenario for Idle resource spending: avoid paying for unnecessary always-on capacity by managing idle resources. Idle provisioned resources may continue to generate charges; matching uptime to need reduces wasted spending. It is not the most direct example of Total cost of ownership.
Question 403
A learner is explaining Amazon S3 storage class selection to colleagues facing this situation: an archive team needs to compare object storage costs between frequently accessed and rarely retrieved data. Which explanation is MOST accurate?
- Savings Plans provide discounts for covered usage in exchange for a one- or three-year commitment to an hourly spend amount.
- On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments.
- S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost.
- Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path.
Explanation
Correct Answer
C:S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost. The explanation directly connects Amazon S3 storage class selection to compare storage duration, retrieval charges and access characteristics of S3 classes for the stated requirement.
Incorrect Answers
A:This statement is true of Savings Plans, which addresses a business expects steady eligible compute spending and can commit to a consistent hourly amount. It does not explain the particular role of Amazon S3 storage class selection; S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost.
B:This statement is true of On-Demand EC2 pricing, which addresses a company needs compute capacity for a short unpredictable project and does not want a long commitment. It does not explain the particular role of Amazon S3 storage class selection; S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost.
D:This statement is true of AWS data transfer charges, which addresses a company compares incoming internet traffic with traffic sent from AWS to external users. It does not explain the particular role of Amazon S3 storage class selection; S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost.
Question 404
A stakeholder is considering Customer EC2 security groups because a project owner must restrict which network connections can reach an EC2 instance. What is the MOST relevant capability or benefit?
- The customer configures identity permissions for access to its own data
- The customer chooses applicable encryption configuration and key-access policies
- The customer selects where to deploy and store its workloads to meet residency rules
- The customer defines and maintains the instance security group rules
Explanation
Correct Answer
D:The customer defines and maintains the instance security group rules. Customers control security-group configuration for their EC2 workloads even though AWS operates the network infrastructure. The stated need is specifically a project owner must restrict which network connections can reach an EC2 instance.
Incorrect Answers
A:This outcome fits Customer IAM permissions: Even on a managed AWS service, customers remain responsible for authorizing who can access their data. The stakeholder requires the more specific capability provided by Customer EC2 security groups, not that separate benefit.
B:This outcome fits Customer encryption choices: Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. The stakeholder requires the more specific capability provided by Customer EC2 security groups, not that separate benefit.
C:This outcome fits Customer choice of AWS Region: AWS provides available Regions, while the customer chooses deployment locations to meet its legal and organizational obligations. The stakeholder requires the more specific capability provided by Customer EC2 security groups, not that separate benefit.
Question 405
Within the Cloud Concepts domain, which business example MOST clearly illustrates AWS Database Migration Service, rather than a different AWS concept?
- A company wants to transfer database content to AWS while limiting downtime
- A company can move a supported virtualized environment to AWS while maintaining its familiar virtualization stack
- A program manager needs a consolidated place to follow the progress of multiple migration activities
- A business must keep a legacy production system on premises until a contractual restriction expires
Explanation
Correct Answer
A:The decisive requirement is: Migrate and optionally replicate data between supported database endpoints. This is the role of AWS Database Migration Service. AWS DMS can transfer data and support change data capture for applicable database migration scenarios.
Incorrect Answers
B:This describes a scenario for Relocating a workload: move compatible virtual machines or virtualized infrastructure with minimal change. Relocating retains much of the underlying virtualization model while shifting where it runs. It is not the most direct example of AWS Database Migration Service.
C:This describes a scenario for AWS Migration Hub: track application migration progress centrally. AWS Migration Hub provides visibility into discovered applications and migration activity across supported migration tools. It is not the most direct example of AWS Database Migration Service.
D:This describes a scenario for Retaining a workload: leave a selected workload in its existing environment for now. Retaining is an intentional decision to defer migration when business or technical constraints make an immediate move inappropriate. It is not the most direct example of AWS Database Migration Service.
Question 406
A testing team needs temporary computing capacity immediately for a newly approved project. Which AWS service or cloud concept is the MOST direct match for this need?
- Managed service operations
- On-demand provisioning
- Elasticity
- Rapid experimentation
Explanation
Correct Answer
B:On-demand provisioning fits the need because aWS self-service resource provisioning reduces procurement lead time for many workloads. The relevant capability or responsibility is: Provision capacity when requested rather than waiting for hardware ordering.
Incorrect Answers
A:Managed service operations is associated with a different use case: an analytics team prefers a managed database rather than operating its own database host. Managed AWS offerings take on selected provisioning and maintenance tasks while customers remain responsible for their data and access policies. The question instead focuses on a testing team needs temporary computing capacity immediately for a newly approved project; On-demand provisioning is the more direct match.
C:Elasticity is associated with a different use case: an online store has unpredictable weekend traffic spikes followed by quiet weekdays. Elasticity aligns live capacity with changing workload demand so idle peak-sized resources do not remain continuously allocated. The question instead focuses on a testing team needs temporary computing capacity immediately for a newly approved project; On-demand provisioning is the more direct match.
D:Rapid experimentation is associated with a different use case: a product group wants to run several short-lived proofs of concept at low initial commitment. On-demand cloud environments make experiments easier to start and stop as new ideas are evaluated. The question instead focuses on a testing team needs temporary computing capacity immediately for a newly approved project; On-demand provisioning is the more direct match.
Question 407
A SaaS app emits business events that must be routed to different AWS targets based on rules. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS Step Functions
- Amazon SES
- Amazon EventBridge
- Amazon Connect
Explanation
Correct Answer
C:Amazon EventBridge fits the need because eventBridge matches events against rules and directs them to supported targets. The relevant capability or responsibility is: Use Amazon EventBridge for event bus routing and integration.
Incorrect Answers
A:AWS Step Functions is associated with a different use case: 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. The question instead focuses on a SaaS app emits business events that must be routed to different AWS targets based on rules; Amazon EventBridge is the more direct match.
B:Amazon SES is associated with a different use case: a company must send transactional confirmation emails from its application. SES provides email sending and related features for business application communications. The question instead focuses on a SaaS app emits business events that must be routed to different AWS targets based on rules; Amazon EventBridge is the more direct match.
D:Amazon Connect is associated with a different use case: 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. The question instead focuses on a SaaS app emits business events that must be routed to different AWS targets based on rules; Amazon EventBridge is the more direct match.
Question 408
A stakeholder is considering AWS Shield because a public application is concerned about distributed denial-of-service traffic. What is the MOST relevant capability or benefit?
- Meet this requirement: an organization needs general recommendations to harden AWS workloads
- Meet this requirement: a small team wants to find certain common AWS account configuration risks through recommendations
- Manage supported security policies centrally
- Support DDoS protection capabilities
Explanation
Correct Answer
D:Use AWS Shield for DDoS protection capabilities. Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities. The stated need is specifically a public application is concerned about distributed denial-of-service traffic.
Incorrect Answers
A:This outcome fits AWS security best practices: AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer. The stakeholder requires the more specific capability provided by AWS Shield, not that separate benefit.
B:This outcome fits AWS Trusted Advisor security checks: Trusted Advisor provides best-practice guidance in supported categories including security, cost and service limits. The stakeholder requires the more specific capability provided by AWS Shield, not that separate benefit.
C:This outcome fits AWS Firewall Manager policy oversight: Firewall Manager helps manage AWS WAF, Shield and related policies across an AWS Organizations environment. The stakeholder requires the more specific capability provided by AWS Shield, not that separate benefit.
Question 409
Within the Cloud Concepts domain, which business example MOST clearly illustrates Managed service operations, rather than a different AWS concept?
- An analytics team prefers a managed database rather than operating its own database host
- A hospital booking service must remain accessible even when one hosting location becomes unavailable
- A media company serves static images to viewers in many countries and wants them delivered near viewers
- A photo service needs stored customer pictures to remain intact despite individual storage hardware failures
Explanation
Correct Answer
A:The decisive requirement is: Reduce routine infrastructure management by consuming a managed service. This is the role of Managed service operations. Managed AWS offerings take on selected provisioning and maintenance tasks while customers remain responsible for their data and access policies.
Incorrect Answers
B:This describes a scenario for High availability: keep the application accessible by using redundant resources and eliminating single points of failure. High availability focuses on minimizing service interruptions through redundancy and service continuity. It is not the most direct example of Managed service operations.
C:This describes a scenario for Edge content delivery: cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users. It is not the most direct example of Managed service operations.
D:This describes a scenario for Storage durability: protect stored objects against underlying component failures. Durability describes the likelihood that stored data remains intact; it is different from immediate service accessibility. It is not the most direct example of Managed service operations.
Question 410
A stakeholder is considering Variable costs because a retailer wants lower cloud expenses during months with fewer transactions. What is the MOST relevant capability or benefit?
- Evaluate use of qualifying existing software licenses subject to vendor and AWS terms
- Let eligible costs rise and fall with actual resource consumption
- Classify cloud usage-based service payments as operating spending
- Reduce repetitive administrative work through consistent automation
Explanation
Correct Answer
B:Let eligible costs rise and fall with actual resource consumption. Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The stated need is specifically a retailer wants lower cloud expenses during months with fewer transactions.
Incorrect Answers
A:This outcome fits Bring Your Own License: BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied. The stakeholder requires the more specific capability provided by Variable costs, not that separate benefit.
C:This outcome fits Operating expenditure: Variable cloud charges generally align with operating expense rather than a customer buying provider hardware. The stakeholder requires the more specific capability provided by Variable costs, not that separate benefit.
D: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 Variable costs, not that separate benefit.
