Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 47
Question 460
A learner is explaining Access keys to colleagues facing this situation: a legacy automation application uses an AWS access-key ID and secret key for API access. Which explanation is MOST accurate?
- IAM Identity Center connects workforce identities and assigns access across AWS accounts and compatible applications.
- Short-lived credentials reduce the time a stolen credential can remain useful compared with persistent access keys.
- Federation integrates identity-provider authentication with AWS access, supporting centralized workforce identity management.
- AWS access keys enable programmatic authentication and must not be committed to public repositories.
Explanation
Correct Answer
D:AWS access keys enable programmatic authentication and must not be committed to public repositories. The explanation directly connects Access keys to treat access keys as sensitive credentials and rotate or replace them where appropriate for the stated requirement.
Incorrect Answers
A:This statement is true of AWS IAM Identity Center, which addresses employees need centralized workforce access to multiple AWS accounts using corporate identities. It does not explain the particular role of Access keys; AWS access keys enable programmatic authentication and must not be committed to public repositories.
B:This statement is true of Temporary security credentials, which addresses a contractor needs access for a limited session without receiving a permanent AWS key. It does not explain the particular role of Access keys; AWS access keys enable programmatic authentication and must not be committed to public repositories.
C:This statement is true of Identity federation, which addresses a company wants staff to authenticate to AWS using its existing corporate identity provider. It does not explain the particular role of Access keys; AWS access keys enable programmatic authentication and must not be committed to public repositories.
Question 461
A project manager compares Retiring an application with other AWS concepts while considering this need: an inventory review discovers a legacy reporting system with no users or business dependency. Which pairing assigns the responsibilities or benefits correctly?
- Retiring an application: decommission an unneeded application rather than migrate it; Refactoring migration: make significant application changes to use cloud-native capabilities
- Retiring an application: make significant application changes to use cloud-native capabilities; Refactoring migration: decommission an unneeded application rather than migrate it
- Retiring an application: replace an existing application with a different product or SaaS solution; Repurchasing migration: decommission an unneeded application rather than migrate it
- Retiring an application: organize organizational readiness across AWS CAF perspectives; AWS Cloud Adoption Framework: decommission an unneeded application rather than migrate it
Explanation
Correct Answer
A:The first pairing identifies Retiring an application with its actual role: decommission an unneeded application rather than migrate it. Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value. The comparison is valid because Refactoring migration instead addresses make significant application changes to use cloud-native capabilities.
Incorrect Answers
B:The roles are swapped. Refactoring migration is associated with make significant application changes to use cloud-native capabilities; Retiring an application instead has the role: Decommission an unneeded application rather than migrate it. Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value.
C:The roles are swapped. Repurchasing migration is associated with replace an existing application with a different product or SaaS solution; Retiring an application instead has the role: Decommission an unneeded application rather than migrate it. Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value.
D:The roles are swapped. AWS Cloud Adoption Framework is associated with organize organizational readiness across AWS CAF perspectives; Retiring an application instead has the role: Decommission an unneeded application rather than migrate it. Retiring eliminates redundant or unused workloads so migration effort is not spent on systems with no continuing value.
Question 462
A stakeholder is considering S3 Standard-IA because a business rarely accesses certain long-lived backup files but needs them rapidly when requested. What is the MOST relevant capability or benefit?
- Support very rarely accessed long-term archival data
- Support infrequently accessed objects with rapid access needs
- Manage backup plans and retention for supported services
- Support managed shared file storage
Explanation
Correct Answer
B:Use S3 Standard-IA for infrequently accessed objects with rapid access needs. S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes. The stated need is specifically a business rarely accesses certain long-lived backup files but needs them rapidly when requested.
Incorrect Answers
A:This outcome fits S3 Glacier Deep Archive: Deep Archive prioritizes low storage cost and accepts retrieval delays, unlike immediately accessed S3 classes. The stakeholder requires the more specific capability provided by S3 Standard-IA, not that separate benefit.
C:This outcome fits AWS Backup: AWS Backup centralizes backup administration across supported resources; it is separate from normal object lifecycle transitions. The stakeholder requires the more specific capability provided by S3 Standard-IA, not that separate benefit.
D:This outcome fits Amazon EFS shared files: EFS is a managed elastic network file system for supported Linux workloads, unlike S3 object API storage. The stakeholder requires the more specific capability provided by S3 Standard-IA, not that separate benefit.
Question 463
A stakeholder is considering AWS Support plans because a business wants to compare the support response options included with different AWS support tiers. What is the MOST relevant capability or benefit?
- Enable available best-practice checks
- Support service and account events
- Support eligible response and contact options
- Identify AWS partners and offerings
Explanation
Correct Answer
C:Review current AWS Support plans for eligible response and contact options. Support benefits and service-level commitments depend on the chosen plan and current AWS support terms. The stated need is specifically a business wants to compare the support response options included with different AWS support tiers.
Incorrect Answers
A:This outcome fits AWS Trusted Advisor: Trusted Advisor provides advisory findings in supported categories; available checks and features depend on account arrangements. The stakeholder requires the more specific capability provided by AWS Support plans, not that separate benefit.
B:This outcome fits AWS Health Dashboard: AWS Health provides information about relevant service disruptions and scheduled changes; it is distinct from an application metric alarm. The stakeholder requires the more specific capability provided by AWS Support plans, not that separate benefit.
D:This outcome fits AWS Partner Network: APN connects customers with AWS partners, such as system integrators and independent software vendors. The stakeholder requires the more specific capability provided by AWS Support plans, not that separate benefit.
Question 464
A stakeholder is considering Security logging retention because an organization wants security logs available for internal investigations for a defined period. What is the MOST relevant capability or benefit?
- Support multi-account governance and consolidated controls
- Record account API activity and identify the calling principal
- Evaluate customer controls and obligations alongside AWS's assurance documentation
- Define appropriate access controls and retention for collected audit logs
Explanation
Correct Answer
D: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. The stated need is specifically an organization wants security logs available for internal investigations for a defined period.
Incorrect Answers
A:This outcome fits AWS Organizations governance: Organizations groups accounts and supports policies and billing consolidation; it does not itself analyze threats. The stakeholder requires the more specific capability provided by Security logging retention, not that separate benefit.
B:This outcome fits AWS CloudTrail API auditing: CloudTrail helps audit actions performed through the console, SDK and API; it differs from performance metrics. The stakeholder requires the more specific capability provided by Security logging retention, not that separate benefit.
C: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 Security logging retention, not that separate benefit.
Question 465
A learner is explaining Encryption at rest to colleagues facing this situation: a business wants to protect stored information on storage volumes or objects. Which explanation is MOST accurate?
- Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
- Macie uses managed data discovery to help identify sensitive information in S3 objects, not network packet attacks.
- CloudHSM provides customer-controlled HSM capacity for supported workloads requiring hardware-backed cryptographic operations.
- CloudWatch supplies monitoring and observability signals, not an authoritative history of every API management change.
Explanation
Correct Answer
A:Encryption at rest protects stored data against certain exposure risks, not data traveling across the network. The explanation directly connects Encryption at rest to enable applicable data-at-rest encryption on storage services for the stated requirement.
Incorrect Answers
B:This statement is true of Amazon Macie sensitive S3 data, which addresses a team needs to discover potentially sensitive information stored within Amazon S3. It does not explain the particular role of Encryption at rest; Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
C:This statement is true of AWS CloudHSM hardware keys, which addresses a company needs dedicated hardware security modules for particular cryptographic key requirements. It does not explain the particular role of Encryption at rest; Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
D:This statement is true of Amazon CloudWatch monitoring, which addresses operations needs metrics and alarms for an AWS workload's performance. It does not explain the particular role of Encryption at rest; Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
Question 466
A project manager compares Network ACLs with other AWS concepts while considering this need: a VPC owner needs network traffic rules at the subnet boundary and wants stateless filtering. Which pairing assigns the responsibilities or benefits correctly?
- Network ACLs: support private service connectivity from a VPC; AWS PrivateLink: use network access control lists for subnet-level traffic rules
- Network ACLs: use network access control lists for subnet-level traffic rules; VPC subnets: divide VPC address space into smaller networks
- Network ACLs: divide VPC address space into smaller networks; VPC subnets: use network access control lists for subnet-level traffic rules
- Network ACLs: support dedicated network connectivity to AWS; AWS Direct Connect: use network access control lists for subnet-level traffic rules
Explanation
Correct Answer
B:The first pairing identifies Network ACLs with its actual role: use network access control lists for subnet-level traffic rules. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior. The comparison is valid because VPC subnets instead addresses use VPC subnets to divide VPC address space into smaller networks.
Incorrect Answers
A:The roles are swapped. AWS PrivateLink is associated with use AWS PrivateLink for private service connectivity from a VPC; Network ACLs instead has the role: Use network access control lists for subnet-level traffic rules. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior.
C:The roles are swapped. VPC subnets is associated with use VPC subnets to divide VPC address space into smaller networks; Network ACLs instead has the role: Use network access control lists for subnet-level traffic rules. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior.
D:The roles are swapped. AWS Direct Connect is associated with use AWS Direct Connect for dedicated network connectivity to AWS; Network ACLs instead has the role: Use network access control lists for subnet-level traffic rules. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior.
Question 467
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: grant only the permissions necessary to perform approved duties?
- IAM roles
- Amazon Cognito
- Principle of least privilege
- AWS STS
Explanation
Correct Answer
C:Principle of least privilege directly addresses this outcome. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access. A common relevant example is: a developer only needs read access to one object storage bucket for a project.
Incorrect Answers
A:IAM roles instead focuses on a different requirement, such as an EC2 application needs AWS API permissions without storing a permanent access key in the server. IAM roles can be assumed to obtain temporary security credentials and avoid embedding long-term keys in applications. It is not the primary match for the requirement described here: grant only the permissions necessary to perform approved duties.
B:Amazon Cognito identity instead focuses on a different requirement, such as a mobile application needs sign-up and authentication for its end users. Cognito focuses on end-user identity for web and mobile applications, not AWS workforce account administration. It is not the primary match for the requirement described here: grant only the permissions necessary to perform approved duties.
D:AWS STS role assumption instead focuses on a different requirement, such as an application needs temporary AWS credentials after assuming an authorized IAM role. STS provides temporary credentials for permitted role or federated sessions; it does not issue physical security tokens. It is not the primary match for the requirement described here: grant only the permissions necessary to perform approved duties.
Question 468
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: use network access control lists for subnet-level traffic rules?
- Amazon Route 53
- Security groups
- Amazon VPC
- Network ACLs
Explanation
Correct Answer
D:Network ACLs directly addresses this outcome. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior. A common relevant example is: a VPC owner needs network traffic rules at the subnet boundary and wants stateless filtering.
Incorrect Answers
A:Amazon Route 53 instead focuses on a different requirement, such as a business needs a managed DNS service for resolving public application domain names. Route 53 supplies managed DNS records and routing policies, rather than acting as a virtual machine host. It is not the primary match for the requirement described here: use network access control lists for subnet-level traffic rules.
B:Security groups instead focuses on a different requirement, such as an EC2 workload should allow only specified inbound and outbound connections at the resource level. Security groups control permitted traffic for associated resources and automatically allow response traffic to allowed flows. It is not the primary match for the requirement described here: use network access control lists for subnet-level traffic rules.
C: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: use network access control lists for subnet-level traffic rules.
Question 469
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: aggregate and prioritize findings from different security detection tools?
- AWS Security Hub
- AWS Artifact compliance reports
- Amazon Macie
- AWS compliance shared model
Explanation
Correct Answer
A:AWS Security Hub directly addresses this outcome. Security Hub centralizes security posture information and findings rather than storing application business data. A common relevant example is: a security operations team wants a consolidated view of findings from multiple AWS security services.
Incorrect Answers
B:AWS Artifact compliance reports instead focuses on a different requirement, such as an auditor asks a company for AWS third-party compliance and assurance documentation. AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements. It is not the primary match for the requirement described here: aggregate and prioritize findings from different security detection tools.
C:Amazon Macie sensitive S3 data instead focuses on a different requirement, such as a team needs to discover potentially sensitive information stored within Amazon S3. Macie uses managed data discovery to help identify sensitive information in S3 objects, not network packet attacks. It is not the primary match for the requirement described here: aggregate and prioritize findings from different security detection tools.
D:AWS compliance shared model instead focuses on a different requirement, such as a regulated company assumes AWS compliance certificates automatically satisfy every customer-specific obligation. AWS compliance programs cover AWS's side of applicable frameworks, while customers must evaluate and satisfy their own duties. It is not the primary match for the requirement described here: aggregate and prioritize findings from different security detection tools.
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.
