Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 53
Question 520
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: record account API activity and identify the calling principal?
- Defense in depth
- AWS Audit Manager
- AWS KMS
- AWS CloudTrail
Explanation
Correct Answer
D:AWS CloudTrail directly addresses this outcome. CloudTrail helps audit actions performed through the console, SDK and API; it differs from performance metrics. A common relevant example is: a security analyst needs to see which principal made an AWS control-plane API call.
Incorrect Answers
A:Defense in depth instead focuses on a different requirement, such as a security team wants more than a single network restriction protecting sensitive records. Defense in depth reduces dependence on a single security mechanism by using multiple complementary safeguards. It is not the primary match for the requirement described here: record account API activity and identify the calling principal.
B:AWS Audit Manager evidence instead focuses on a different requirement, such as a compliance team needs help collecting evidence against a recurring internal control assessment. AWS Audit Manager can collect evidence for assessments but does not replace an organization's compliance decisions. It is not the primary match for the requirement described here: record account API activity and identify the calling principal.
C:AWS KMS managed keys instead focuses on a different requirement, such as an application team needs centralized control of encryption key use and auditability. AWS KMS manages keys and enforces key-use controls for integrated services; it is not a general database service. It is not the primary match for the requirement described here: record account API activity and identify the calling principal.
Question 521
A stakeholder is considering Customer EC2 guest operating system because a business runs its own Linux installation on an Amazon EC2 virtual machine. What is the MOST relevant capability or benefit?
- The customer maintains guest operating system configuration and security updates
- The customer must correct the bucket access policy and exposure settings
- The customer is responsible for the function code and its business logic
- AWS maintains the physical host and underlying cloud virtualization infrastructure
Explanation
Correct Answer
A:The customer maintains guest operating system configuration and security updates. For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts. The stated need is specifically a business runs its own Linux installation on an Amazon EC2 virtual machine.
Incorrect Answers
B:This outcome fits Customer S3 bucket access: AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. The stakeholder requires the more specific capability provided by Customer EC2 guest operating system, not that separate benefit.
C:This outcome fits Customer Lambda function code: Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. The stakeholder requires the more specific capability provided by Customer EC2 guest operating system, not that separate benefit.
D: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 Customer EC2 guest operating system, not that separate benefit.
Question 522

D:The first pairing identifies S3 Standard-IA with its actual role: 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 comparison is valid because S3 Glacier Deep Archive instead addresses use S3 Glacier Deep Archive for very rarely accessed long-term archival data.
Incorrect Answers
A:The roles are swapped. AWS Backup is associated with use AWS Backup to manage backup plans and retention for supported services; S3 Standard-IA instead has the role: 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.
B:The roles are swapped. S3 Glacier Deep Archive is associated with use S3 Glacier Deep Archive for very rarely accessed long-term archival data; S3 Standard-IA instead has the role: 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.
C:The roles are swapped. Amazon EFS is associated with use Amazon Elastic File System for managed shared file storage; S3 Standard-IA instead has the role: Use S3 Standard-IA for infrequently accessed objects with rapid access needs.

Question 525
Within the Cloud Concepts domain, which business example MOST clearly illustrates AWS Cloud Adoption Framework, rather than a different AWS concept?
- Executives need a structured view of people, governance, business, platform, security, and operations during cloud adoption
- A business is willing to redesign a tightly coupled application into cloud-native components
- An inventory review discovers a legacy reporting system with no users or business dependency
- An organization must transfer a very large volume of data from a remote site with insufficient network bandwidth
Explanation
Correct Answer
A:The decisive requirement is: Organize organizational readiness across AWS CAF perspectives. This is the role of AWS Cloud Adoption Framework. AWS CAF helps align business and technology stakeholders throughout cloud adoption instead of treating migration as a server-copy exercise.
Incorrect Answers
B:This describes a scenario for Refactoring migration: make significant application changes to use cloud-native capabilities. Refactoring transforms the application architecture, rather than simply moving the existing runtime to the cloud. It is not the most direct example of AWS Cloud Adoption Framework.
C:This describes a scenario for Retiring an application: 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. It is not the most direct example of AWS Cloud Adoption Framework.
D:This describes a scenario for AWS Snow Family: use physical AWS data transfer devices where online transfer is impractical. AWS Snow devices support moving large datasets when transferring everything over a network is slow or constrained. It is not the most direct example of AWS Cloud Adoption Framework.
Question 526
A learner is explaining Customer EC2 guest operating system to colleagues facing this situation: a business runs its own Linux installation on an Amazon EC2 virtual machine. Which explanation is MOST accurate?
- AWS cannot determine the business sensitivity of customer content; data classification and applicable handling policies belong to the customer.
- For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts.
- Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud.
- Customers control security-group configuration for their EC2 workloads even though AWS operates the network infrastructure.
Explanation
Correct Answer
B:For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts. The explanation directly connects Customer EC2 guest operating system to the customer maintains guest operating system configuration and security updates for the stated requirement.
Incorrect Answers
A:This statement is true of Customer data classification, which addresses a regulated company must identify which of its uploaded records contain sensitive personal information. It does not explain the particular role of Customer EC2 guest operating system; For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts.
C:This statement is true of AWS physical data center security, which addresses an AWS customer asks who guards the buildings where AWS runs underlying server hardware. It does not explain the particular role of Customer EC2 guest operating system; For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts.
D:This statement is true of Customer EC2 security groups, which addresses a project owner must restrict which network connections can reach an EC2 instance. It does not explain the particular role of Customer EC2 guest operating system; For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts.
Question 527
A learner is explaining AWS Artifact compliance reports to colleagues facing this situation: an auditor asks a company for AWS third-party compliance and assurance documentation. Which explanation is MOST accurate?
- AWS compliance programs cover AWS's side of applicable frameworks, while customers must evaluate and satisfy their own duties.
- Inspector identifies package and supported workload vulnerabilities; it is not a replacement for data classification.
- AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements.
- CloudTrail helps audit actions performed through the console, SDK and API; it differs from performance metrics.
Explanation
Correct Answer
C:AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements. The explanation directly connects AWS Artifact compliance reports to retrieve AWS compliance reports and related agreements using AWS Artifact for the stated requirement.
Incorrect Answers
A:This statement is true of AWS compliance shared model, which addresses a regulated company assumes AWS compliance certificates automatically satisfy every customer-specific obligation. It does not explain the particular role of AWS Artifact compliance reports; AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements.
B:This statement is true of Amazon Inspector vulnerability findings, which addresses an administrator wants continuous assessments of supported workloads for software vulnerabilities. It does not explain the particular role of AWS Artifact compliance reports; AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements.
D:This statement is true of AWS CloudTrail API auditing, which addresses a security analyst needs to see which principal made an AWS control-plane API call. It does not explain the particular role of AWS Artifact compliance reports; AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements.
Question 528
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates AWS data transfer charges, rather than a different AWS concept?
- Finance wants to compare flexible compute consumption with paying less under a usage commitment
- A company needs compute capacity for a short unpredictable project and does not want a long commitment
- An enterprise runs a predictable EC2 workload and can make a qualifying commitment
- A company compares incoming internet traffic with traffic sent from AWS to external users
Explanation
Correct Answer
D:The decisive requirement is: Account for service- and route-dependent data transfer pricing. This is the role of AWS data transfer charges. Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path.
Incorrect Answers
A:This describes a scenario for Compute commitment flexibility: trade some flexibility for eligible discounted capacity or spending commitments. Commitment options can lower qualifying compute costs, but suitability depends on sustained predictable usage and terms. It is not the most direct example of AWS data transfer charges.
B:This describes a scenario for On-Demand EC2 pricing: pay for eligible compute usage without a long-term purchase commitment. On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments. It is not the most direct example of AWS data transfer charges.
C:This describes a scenario for Reserved Instances: consider EC2 Reserved Instances for eligible long-running instance usage discounts. Reserved Instances offer pricing benefits for qualifying EC2 usage with a term commitment and specified attributes. It is not the most direct example of AWS data transfer charges.
Question 529
A project manager compares Encryption at rest with other AWS concepts while considering this need: a business wants to protect stored information on storage volumes or objects. Which pairing assigns the responsibilities or benefits correctly?
- Encryption at rest: enable applicable data-at-rest encryption on storage services; Security logging retention: define appropriate access controls and retention for collected audit logs
- Encryption at rest: track configuration changes and evaluate resource compliance over time; AWS Config: enable applicable data-at-rest encryption on storage services

Explanation
Correct Answer
A:The first pairing identifies Encryption at rest with its actual role: enable applicable data-at-rest encryption on storage services. Encryption at rest protects stored data against certain exposure risks, not data traveling across the network. The comparison is valid because Security logging retention instead addresses define appropriate access controls and retention for collected audit logs.
Incorrect Answers
B:The roles are swapped. AWS Config is associated with record configuration changes and evaluate resource compliance with AWS Config; Encryption at rest instead has the role: Enable applicable data-at-rest encryption on storage services. Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
C:The roles are swapped. Security logging retention is associated with define appropriate access controls and retention for collected audit logs; Encryption at rest instead has the role: Enable applicable data-at-rest encryption on storage services. Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
D:The roles are swapped. AWS Artifact compliance reports is associated with retrieve AWS compliance reports and related agreements using AWS Artifact; Encryption at rest instead has the role: Enable applicable data-at-rest encryption on storage services. Encryption at rest protects stored data against certain exposure risks, not data traveling across the network.
