Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 43
Question 420
An analytics node needs high local disk throughput for temporary data processing. Which AWS service or cloud concept is the MOST direct match for this need?
- Amazon Lightsail
- Elastic Load Balancing
- Amazon EC2
- Storage-optimized EC2
Explanation
Correct Answer
D:Storage-optimized EC2 fits the need because storage-optimized instance families are designed for high local storage I/O and throughput needs. The relevant capability or responsibility is: Choose an EC2 storage-optimized instance family where local storage performance is central.
Incorrect Answers
A:Amazon Lightsail is associated with a different use case: a small business wants a straightforward virtual private server with bundled resources. Lightsail offers simple virtual server and related resource plans for common small applications and websites. The question instead focuses on an analytics node needs high local disk throughput for temporary data processing; Storage-optimized EC2 is the more direct match.
B:Elastic Load Balancing is associated with a different use case: a website needs inbound requests distributed among several healthy application targets. Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance. The question instead focuses on an analytics node needs high local disk throughput for temporary data processing; Storage-optimized EC2 is the more direct match.
C: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 an analytics node needs high local disk throughput for temporary data processing; Storage-optimized EC2 is the more direct match.
Question 421
A stakeholder is considering Shared responsibility varies by service because a technology leader compares the management obligations of EC2, RDS and Lambda. What is the MOST relevant capability or benefit?
- Customer operational responsibilities generally decrease as more service layers become AWS-managed
- The customer classifies its own data and defines appropriate access requirements
- AWS maintains the physical host and underlying cloud virtualization infrastructure
- The customer configures identity permissions for access to its own data
Explanation
Correct Answer
A:Customer operational responsibilities generally decrease as more service layers become AWS-managed. Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda. The stated need is specifically a technology leader compares the management obligations of EC2, RDS and Lambda.
Incorrect Answers
B:This outcome fits Customer data classification: AWS cannot determine the business sensitivity of customer content; data classification and applicable handling policies belong to the customer. The stakeholder requires the more specific capability provided by Shared responsibility varies by service, not that separate benefit.
C:This outcome fits AWS EC2 host infrastructure: AWS is responsible for facilities, physical servers and underlying cloud infrastructure for EC2. The stakeholder requires the more specific capability provided by Shared responsibility varies by service, not that separate benefit.
D: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 Shared responsibility varies by service, not that separate benefit.
Question 422
A learner is explaining Elastic Load Balancing to colleagues facing this situation: a website needs inbound requests distributed among several healthy application targets. Which explanation is MOST accurate?
- Fargate supplies compute capacity for supported container tasks without customers administering container hosts.
- Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance.
- EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs.
- ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
Explanation
Correct Answer
B:Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance. The explanation directly connects Elastic Load Balancing to use Elastic Load Balancing to distribute incoming workload traffic for the stated requirement.
Incorrect Answers
A:This statement is true of AWS Fargate, which addresses a development team wants to run supported containers without managing the underlying EC2 host fleet. It does not explain the particular role of Elastic Load Balancing; Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance.
C:This statement is true of Amazon EKS, which addresses an organization wants managed Kubernetes control-plane capabilities for containerized workloads. It does not explain the particular role of Elastic Load Balancing; Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance.
D:This statement is true of Amazon ECS, which addresses an application team needs AWS-native orchestration of container workloads. It does not explain the particular role of Elastic Load Balancing; Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance.
Question 423
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: the customer is responsible for the function code and its business logic?
- Customer S3 bucket access
- Customer encryption choices
- Customer Lambda function code
- Customer choice of AWS Region
Explanation
Correct Answer
C:Customer Lambda function code directly addresses this outcome. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. A common relevant example is: a Lambda function processes user data using application code written by a development team.
Incorrect Answers
A:Customer S3 bucket access instead focuses on a different requirement, such as a team accidentally publishes an S3 bucket containing internal reports. AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. It is not the primary match for the requirement described here: the customer is responsible for the function code and its business logic.
B: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: the customer is responsible for the function code and its business logic.
D: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: the customer is responsible for the function code and its business logic.
Question 424
A stakeholder is considering Amazon Macie because a team needs to discover potentially sensitive information stored within Amazon S3. What is the MOST relevant capability or benefit?
- Evaluate customer controls and obligations alongside AWS's assurance documentation
- Monitor metrics, logs and alarm conditions for workloads
- Organize control evidence collection
- Detect and classify sensitive S3 data
Explanation
Correct Answer
D:Use Amazon Macie to detect and classify sensitive S3 data. Macie uses managed data discovery to help identify sensitive information in S3 objects, not network packet attacks. The stated need is specifically a team needs to discover potentially sensitive information stored within Amazon S3.
Incorrect Answers
A:This outcome fits AWS compliance shared model: AWS compliance programs cover AWS's side of applicable frameworks, while customers must evaluate and satisfy their own duties. The stakeholder requires the more specific capability provided by Amazon Macie, not that separate benefit.
B:This outcome fits Amazon CloudWatch monitoring: CloudWatch supplies monitoring and observability signals, not an authoritative history of every API management change. The stakeholder requires the more specific capability provided by Amazon Macie, not that separate benefit.
C:This outcome fits AWS Audit Manager evidence: AWS Audit Manager can collect evidence for assessments but does not replace an organization's compliance decisions. The stakeholder requires the more specific capability provided by Amazon Macie, not that separate benefit.
Question 425
A project manager compares Amazon EventBridge with other AWS concepts while considering this need: a SaaS app emits business events that must be routed to different AWS targets based on rules. Which pairing assigns the responsibilities or benefits correctly?
- Amazon EventBridge: support event bus routing and integration; Amazon SES: support application email delivery
- Amazon EventBridge: support managed workflow orchestration; AWS Step Functions: support event bus routing and integration
- Amazon EventBridge: support application email delivery; Amazon SES: support event bus routing and integration
- Amazon EventBridge: support managed contact center capabilities; Amazon Connect: support event bus routing and integration
Explanation
Correct Answer
A:The first pairing identifies Amazon EventBridge with its actual role: use Amazon EventBridge for event bus routing and integration. EventBridge matches events against rules and directs them to supported targets. The comparison is valid because Amazon SES instead addresses use Amazon Simple Email Service for application email delivery.
Incorrect Answers
B:The roles are swapped. AWS Step Functions is associated with use AWS Step Functions for managed workflow orchestration; Amazon EventBridge instead has the role: Use Amazon EventBridge for event bus routing and integration. EventBridge matches events against rules and directs them to supported targets.
C:The roles are swapped. Amazon SES is associated with use Amazon Simple Email Service for application email delivery; Amazon EventBridge instead has the role: Use Amazon EventBridge for event bus routing and integration. EventBridge matches events against rules and directs them to supported targets.
D:The roles are swapped. Amazon Connect is associated with use Amazon Connect for managed contact center capabilities; Amazon EventBridge instead has the role: Use Amazon EventBridge for event bus routing and integration. EventBridge matches events against rules and directs them to supported targets.
Question 426
Within the Security and Compliance domain, which business example MOST clearly illustrates Data residency considerations, rather than a different AWS concept?
- An organization wants security logs available for internal investigations for a defined period
- A healthcare organization has contractual restrictions on the country in which records may be stored
- A compliance team needs help collecting evidence against a recurring internal control assessment
- An organization must inspect how an AWS resource configuration changed over time
Explanation
Correct Answer
B:The decisive requirement is: Evaluate Region and service data-location capabilities against applicable residency requirements. This is the role of Data residency considerations. Compliance and data-location choices remain customer decisions even when AWS operates the service infrastructure.
Incorrect Answers
A:This describes a scenario for Security logging retention: define appropriate access controls and retention for collected audit logs. Collecting logs alone is insufficient unless their access, preservation and lifecycle align with organizational policy. It is not the most direct example of Data residency considerations.
C:This describes a scenario for AWS Audit Manager evidence: use AWS Audit Manager to organize control evidence collection. AWS Audit Manager can collect evidence for assessments but does not replace an organization's compliance decisions. It is not the most direct example of Data residency considerations.
D:This describes a scenario for AWS Config resource history: record configuration changes and evaluate resource compliance with AWS Config. AWS Config tracks supported resource configuration history and rules rather than serving as a generic application log service. It is not the most direct example of Data residency considerations.
Question 427
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support managed DNS and related domain routing features?
- AWS Direct Connect
- Network ACLs
- Amazon Route 53
- Amazon VPC
Explanation
Correct Answer
C:Amazon Route 53 directly addresses this outcome. Route 53 supplies managed DNS records and routing policies, rather than acting as a virtual machine host. A common relevant example is: a business needs a managed DNS service for resolving public application domain names.
Incorrect Answers
A:AWS Direct Connect instead focuses on a different requirement, such as an enterprise wants a dedicated private network connection between its premises and AWS. Direct Connect provides private physical network connectivity through supported locations; encryption is a separate consideration. It is not the primary match for the requirement described here: support managed DNS and related domain routing features.
B:Network ACLs instead focuses on a different requirement, such as a VPC owner needs network traffic rules at the subnet boundary and wants stateless filtering. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior. It is not the primary match for the requirement described here: support managed DNS and related domain routing features.
D:Amazon VPC instead focuses on a different requirement, such as a team wants a logically isolated network environment for its AWS compute resources. A VPC is a logically isolated virtual network in which customers can organize subnets, routes and connectivity. It is not the primary match for the requirement described here: support managed DNS and related domain routing features.
Question 428
A project manager compares AWS Knowledge Center with other AWS concepts while considering this need: an AWS user wants AWS-authored answers to common service troubleshooting and account questions. Which pairing assigns the responsibilities or benefits correctly?
- AWS Knowledge Center: meet this requirement: an organization needs general recommendations to harden AWS workloads; AWS security best practices: support documented guidance
- AWS Knowledge Center: meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads; AWS Marketplace: support documented guidance
- AWS Knowledge Center: enable supported cross-account resource sharing; AWS Resource Access Manager: support documented guidance
- AWS Knowledge Center: support documented guidance; AWS Marketplace: meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads
Explanation
Correct Answer
D:The first pairing identifies AWS Knowledge Center with its actual role: use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool. The comparison is valid because AWS Marketplace security software instead addresses find third-party software offerings through AWS Marketplace.
Incorrect Answers
A:The roles are swapped. AWS security best practices is associated with use AWS security best-practice resources and service-specific recommendations; AWS Knowledge Center instead has the role: Use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool.
B:The roles are swapped. AWS Marketplace is associated with find third-party software offerings through AWS Marketplace; AWS Knowledge Center instead has the role: Use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool.
C:The roles are swapped. AWS Resource Access Manager is associated with use AWS Resource Access Manager for supported cross-account resource sharing; AWS Knowledge Center instead has the role: Use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool.
Question 429
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: evaluate use of qualifying existing software licenses subject to vendor and AWS terms?
- Bring Your Own License
- Automation savings
- Operating expenditure
- Capital expenditure
Explanation
Correct Answer
A:Bring Your Own License directly addresses this outcome. BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied. A common relevant example is: a company has eligible existing software licenses that might be usable on a cloud host.
Incorrect Answers
B:Automation savings instead focuses on a different requirement, such as 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. It is not the primary match for the requirement described here: evaluate use of qualifying existing software licenses subject to vendor and AWS terms.
C:Operating expenditure instead focuses on a different requirement, such as a business pays recurring usage charges for AWS resources it uses this month. Variable cloud charges generally align with operating expense rather than a customer buying provider hardware. It is not the primary match for the requirement described here: evaluate use of qualifying existing software licenses subject to vendor and AWS terms.
D:Capital expenditure instead focuses on a different requirement, such as 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. It is not the primary match for the requirement described here: evaluate use of qualifying existing software licenses subject to vendor and AWS terms.
Question 430
A learner is explaining AWS Step Functions to colleagues facing this situation: a business process needs a coordinated sequence of several AWS service tasks with branching states. Which explanation is MOST accurate?
- EventBridge matches events against rules and directs them to supported targets.
- Step Functions models stateful application workflows and service coordination rather than storing the business records.
- SQS buffers work items for asynchronous consumption, unlike a publish-subscribe notification fan-out service.
- IoT Core helps connect and manage communications with devices, not an end-user email service.
Explanation
Correct Answer
B:Step Functions models stateful application workflows and service coordination rather than storing the business records. The explanation directly connects AWS Step Functions to use AWS Step Functions for managed workflow orchestration for the stated requirement.
Incorrect Answers
A:This statement is true of Amazon EventBridge, which addresses a SaaS app emits business events that must be routed to different AWS targets based on rules. It does not explain the particular role of AWS Step Functions; Step Functions models stateful application workflows and service coordination rather than storing the business records.
C:This statement is true of Amazon SQS, which addresses an order processing system wants queued messages so producers and workers do not need to run at the same speed. It does not explain the particular role of AWS Step Functions; Step Functions models stateful application workflows and service coordination rather than storing the business records.
D:This statement is true of AWS IoT Core, which addresses a manufacturer wants connected devices to exchange messages securely with cloud applications. It does not explain the particular role of AWS Step Functions; Step Functions models stateful application workflows and service coordination rather than storing the business records.
