Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 48
Question 470
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates AWS Fargate, rather than a different AWS concept?
- A simulation workload spends most of its time performing CPU-intensive numerical calculations
- A development team wants to run supported containers without managing the underlying EC2 host fleet
- A retail site needs more EC2 instances during traffic spikes and fewer when usage falls
- A software vendor needs full control of a virtual machine operating system for a legacy application
Explanation
Correct Answer
B:The decisive requirement is: Use AWS Fargate for serverless container compute. This is the role of AWS Fargate. Fargate supplies compute capacity for supported container tasks without customers administering container hosts.
Incorrect Answers
A:This describes a scenario for Compute-optimized EC2: choose an EC2 compute-optimized instance family for CPU-heavy work. Compute-optimized instances provide a high ratio of compute performance for suitable CPU-bound applications. It is not the most direct example of AWS Fargate.
C:This describes a scenario for EC2 Auto Scaling: use Amazon EC2 Auto Scaling to adjust instance capacity based on demand. EC2 Auto Scaling can add or remove instances based on policies to help meet capacity and availability needs. It is not the most direct example of AWS Fargate.
D:This describes a scenario for Amazon EC2 virtual servers: use Amazon EC2 for configurable virtual compute instances. EC2 offers virtual servers with selectable instance types and customer-managed guest operating systems. It is not the most direct example of AWS Fargate.
Question 471
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: trade some flexibility for eligible discounted capacity or spending commitments?
- EC2 On-Demand Instances
- On-Demand Capacity Reservations
- Compute commitment flexibility
- Amazon S3 storage class selection
Explanation
Correct Answer
C:Compute commitment flexibility directly addresses this outcome. Commitment options can lower qualifying compute costs, but suitability depends on sustained predictable usage and terms. A common relevant example is: finance wants to compare flexible compute consumption with paying less under a usage commitment.
Incorrect Answers
A: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: trade some flexibility for eligible discounted capacity or spending commitments.
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: trade some flexibility for eligible discounted capacity or spending commitments.
D:S3 storage-class pricing instead focuses on a different requirement, such as an archive team needs to compare object storage costs between frequently accessed and rarely retrieved data. S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost. It is not the primary match for the requirement described here: trade some flexibility for eligible discounted capacity or spending commitments.
Question 472
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates AWS edge location, rather than a different AWS concept?
- An internet-facing app has regional endpoints and needs stable global entry points for traffic routing
- A government customer requires that certain datasets be stored in a specified legal jurisdiction
- A company is selecting a separate geographic AWS location for a workload with residency requirements
- A global website wants cached content served closer to its end users
Explanation
Correct Answer
D:The decisive requirement is: Use edge locations as points near users for supported edge services. This is the role of AWS edge location. AWS edge locations support services such as CloudFront and reduce delivery distance for content or requests.
Incorrect Answers
A:This describes a scenario for AWS Global Accelerator: use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints. It is not the most direct example of AWS edge location.
B:This describes a scenario for Data sovereignty Region choice: select an appropriate available AWS Region and check service data-location behavior. Region choice is a customer decision for residency compliance, subject to service availability and contractual requirements. It is not the most direct example of AWS edge location.
C:This describes a scenario for AWS Region: choose an AWS Region to select a geographic cloud infrastructure location. A Region is a geographically separate area containing multiple Availability Zones; customers select deployment Regions. It is not the most direct example of AWS edge location.
Question 473
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support database transfer and applicable ongoing replication?
- AWS Database Migration Service
- Amazon ElastiCache
- Amazon DynamoDB
- Amazon Redshift
Explanation
Correct Answer
A:AWS Database Migration Service directly addresses this outcome. Database Migration Service helps migrate or replicate supported databases; it is not itself an application database engine. A common relevant example is: an enterprise needs help migrating data from a supported existing database to another endpoint.
Incorrect Answers
B:Amazon ElastiCache instead focuses on a different requirement, such as 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. It is not the primary match for the requirement described here: support database transfer and applicable ongoing replication.
C:Amazon DynamoDB instead focuses on a different requirement, such as a game needs low-latency access to large volumes of key-value player state without managing servers. DynamoDB supports key-value and document data models and is not a general-purpose relational SQL database. It is not the primary match for the requirement described here: support database transfer and applicable ongoing replication.
D:Amazon Redshift instead focuses on a different requirement, such as a data team needs a managed warehouse for analytical SQL queries across large structured datasets. Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store. It is not the primary match for the requirement described here: support database transfer and applicable ongoing replication.
Question 474
A stakeholder is considering Customer IAM permissions because an organization must decide which employees can read an S3 bucket in its AWS account. What is the MOST relevant capability or benefit?
- The customer defines and maintains the instance security group rules
- The customer configures identity permissions for access to its own data
- The customer chooses applicable encryption configuration and key-access policies
- Customer operational responsibilities generally decrease as more service layers become AWS-managed
Explanation
Correct Answer
B:The customer configures identity permissions for access to its own data. Even on a managed AWS service, customers remain responsible for authorizing who can access their data. The stated need is specifically an organization must decide which employees can read an S3 bucket in its AWS account.
Incorrect Answers
A:This outcome fits Customer EC2 security groups: Customers control security-group configuration for their EC2 workloads even though AWS operates the network infrastructure. The stakeholder requires the more specific capability provided by Customer IAM permissions, not that separate benefit.
C: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 IAM permissions, not that separate benefit.
D:This outcome fits Shared responsibility varies by service: Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda. The stakeholder requires the more specific capability provided by Customer IAM permissions, not that separate benefit.
Question 475
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: track spending or usage against defined budget thresholds?
- AWS Pricing Calculator
- AWS Cost and Usage Report
- AWS Budgets
- AWS Free Tier
Explanation
Correct Answer
C:AWS Budgets directly addresses this outcome. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor. A common relevant example is: a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold.
Incorrect Answers
A:AWS Pricing Calculator instead focuses on a different requirement, such as a solutions advisor wants to estimate charges for a proposed AWS environment before it is created. Pricing Calculator models estimated charges from selected assumptions rather than reading an existing account's actual spending. It is not the primary match for the requirement described here: track spending or usage against defined budget thresholds.
B:AWS Cost and Usage Report instead focuses on a different requirement, such as an organization needs granular line-item records of AWS charges for internal analytics. Cost and Usage Reports provide detailed charge records suitable for custom analysis rather than just high-level charts. It is not the primary match for the requirement described here: track spending or usage against defined budget thresholds.
D:AWS Free Tier instead focuses on a different requirement, such as a new learner wants to understand eligible introductory usage offers and their limits. AWS Free Tier offers depend on account eligibility, service and current pricing terms; excess usage can still produce charges. It is not the primary match for the requirement described here: track spending or usage against defined budget thresholds.
Question 476
A business must keep a legacy production system on premises until a contractual restriction expires. Which AWS service or cloud concept is the MOST direct match for this need?
- Replatforming migration
- Relocating a workload
- AWS Application Migration Service
- Retaining a workload
Explanation
Correct Answer
D:Retaining a workload fits the need because retaining is an intentional decision to defer migration when business or technical constraints make an immediate move inappropriate. The relevant capability or responsibility is: Leave a selected workload in its existing environment for now.
Incorrect Answers
A: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 a business must keep a legacy production system on premises until a contractual restriction expires; Retaining a workload is the more direct match.
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 a business must keep a legacy production system on premises until a contractual restriction expires; Retaining a workload is the more direct match.
C:AWS Application Migration Service is associated with a different use case: an enterprise needs to lift and shift many supported physical or virtual servers to AWS. AWS Application Migration Service supports continuous replication and cutover for eligible servers. The question instead focuses on a business must keep a legacy production system on premises until a contractual restriction expires; Retaining a workload is the more direct match.
Question 477
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support application-user authentication and identity features?
- Amazon Cognito
- Access keys
- IAM policies
- IAM users
Explanation
Correct Answer
A:Amazon Cognito directly addresses this outcome. Cognito focuses on end-user identity for web and mobile applications, not AWS workforce account administration. A common relevant example is: a mobile application needs sign-up and authentication for its end users.
Incorrect Answers
B:Access keys instead focuses on a different requirement, such as a legacy automation application uses an AWS access-key ID and secret key for API access. AWS access keys enable programmatic authentication and must not be committed to public repositories. It is not the primary match for the requirement described here: support application-user authentication and identity features.
C:IAM policies instead focuses on a different requirement, such as a company needs a document specifying allowed or denied AWS actions on selected resources. An IAM policy expresses permissions; it is not itself a human identity or a network firewall. It is not the primary match for the requirement described here: support application-user authentication and identity features.
D:IAM users instead focuses on a different requirement, such as an organization must represent an individual with long-term credentials in one AWS account. IAM users are identities within an account; organizations generally favor federation and short-lived credentials where suitable. It is not the primary match for the requirement described here: support application-user authentication and identity features.
Question 478
An online store has unpredictable weekend traffic spikes followed by quiet weekdays. Which AWS service or cloud concept is the MOST direct match for this need?
- Scalability
- Elasticity
- High availability
- Edge content delivery
Explanation
Correct Answer
B:Elasticity fits the need because elasticity aligns live capacity with changing workload demand so idle peak-sized resources do not remain continuously allocated. The relevant capability or responsibility is: Adjust allocated resources upward and downward as actual demand changes.
Incorrect Answers
A:Scalability is associated with a different use case: a research portal expects sustained growth from thousands to millions of visitors over several years. Scalability is the ability to handle greater load by adding resources or increasing their capacity as an organization grows. The question instead focuses on an online store has unpredictable weekend traffic spikes followed by quiet weekdays; Elasticity is the more direct match.
C: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 an online store has unpredictable weekend traffic spikes followed by quiet weekdays; Elasticity is the more direct match.
D:Edge content delivery is associated with a different use case: a media company serves static images to viewers in many countries and wants them delivered near viewers. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users. The question instead focuses on an online store has unpredictable weekend traffic spikes followed by quiet weekdays; Elasticity is the more direct match.
Question 479
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts?
- Cost Categories
- AWS Billing console
- Consolidated billing
- AWS Budgets
Explanation
Correct Answer
C:Consolidated billing directly addresses this outcome. Consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. A common relevant example is: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts.
Incorrect Answers
A: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: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts.
B:AWS Billing console instead focuses on a different requirement, such as an account administrator wants to inspect current billing information and payment-related account details. The billing console presents charges and payment information; budget alerts and granular reports are separate tools. It is not the primary match for the requirement described here: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts.
D:AWS Budgets instead focuses on a different requirement, such as a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor. It is not the primary match for the requirement described here: meet this requirement: a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts.
Question 480
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: aWS secures the physical facilities that host its cloud infrastructure?
- Customer encryption choices
- Customer choice of AWS Region
- Customer IAM permissions
- AWS physical data center security
Explanation
Correct Answer
D:AWS physical data center security directly addresses this outcome. Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud. A common relevant example is: an AWS customer asks who guards the buildings where AWS runs underlying server hardware.
Incorrect Answers
A:Customer encryption choices instead focuses on a different requirement, such as a company wants to ensure its application stores sensitive objects with required encryption settings. Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. It is not the primary match for the requirement described here: aWS secures the physical facilities that host its cloud infrastructure.
B:Customer choice of AWS Region instead focuses on a different requirement, such as a business contract requires some client records to remain in a specified geographic jurisdiction. AWS provides available Regions, while the customer chooses deployment locations to meet its legal and organizational obligations. It is not the primary match for the requirement described here: aWS secures the physical facilities that host its cloud infrastructure.
C:Customer IAM permissions instead focuses on a different requirement, such as an organization must decide which employees can read an S3 bucket in its AWS account. Even on a managed AWS service, customers remain responsible for authorizing who can access their data. It is not the primary match for the requirement described here: aWS secures the physical facilities that host its cloud infrastructure.
