Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 113
Question 1120
A stakeholder is considering IAM groups because a team needs to assign the same AWS permissions to several IAM users. What is the MOST relevant capability or benefit?
- Meet this requirement: an application needs controlled storage and rotation of a database password
- Provide temporary credentials to the workload
- Require MFA for eligible AWS sign-in identities
- Manage shared user permissions
Explanation
Correct Answer
D:Use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles. The stated need is specifically a team needs to assign the same AWS permissions to several IAM users.
Incorrect Answers
A:This outcome fits AWS Secrets Manager: Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
B:This outcome fits IAM roles: IAM roles can be assumed to obtain temporary security credentials and avoid embedding long-term keys in applications. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
C:This outcome fits Multi-factor authentication: MFA requires another authentication factor beyond a password and reduces risks from compromised passwords. The stakeholder requires the more specific capability provided by IAM groups, not that separate benefit.
Question 1121
A project manager compares Principle of least privilege with other AWS concepts while considering this need: a developer only needs read access to one object storage bucket for a project. Which pairing assigns the responsibilities or benefits correctly?
- Principle of least privilege: grant only the permissions necessary to perform approved duties; IAM policies: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources
- Principle of least privilege: federate existing enterprise identities instead of issuing separate permanent credentials; Identity federation: grant only the permissions necessary to perform approved duties
- Principle of least privilege: meet this requirement: a company needs a document specifying allowed or denied AWS actions on selected resources; IAM policies: grant only the permissions necessary to perform approved duties
- Principle of least privilege: support application-user authentication and identity features; Amazon Cognito: grant only the permissions necessary to perform approved duties
Explanation
Correct Answer
A:The first pairing identifies Principle of least privilege with its actual role: grant only the permissions necessary to perform approved duties. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access. The comparison is valid because IAM policies instead addresses use IAM policy statements that define access permissions.
Incorrect Answers
B:The roles are swapped. Identity federation is associated with federate existing enterprise identities instead of issuing separate permanent credentials; Principle of least privilege instead has the role: Grant only the permissions necessary to perform approved duties. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access.
C:The roles are swapped. IAM policies is associated with use IAM policy statements that define access permissions; Principle of least privilege instead has the role: Grant only the permissions necessary to perform approved duties. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access.
D:The roles are swapped. Amazon Cognito is associated with use Amazon Cognito for application-user authentication and identity features; Principle of least privilege instead has the role: Grant only the permissions necessary to perform approved duties. Least privilege restricts permissions to required actions and resources rather than granting broad administrator access.
Question 1122
A learner is explaining Capital expenditure to colleagues facing this situation: a company buys servers and pays the purchase cost before those servers are used. Which explanation is MOST accurate?
- Rightsizing replaces persistently oversized resources with suitable capacities to improve cost efficiency.
- Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption.
- Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.
- License-included pricing is distinct from providing a separately acquired customer license under BYOL.
Explanation
Correct Answer
B:Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption. The explanation directly connects Capital expenditure to classify upfront infrastructure equipment purchases as capital spending for the stated requirement.
Incorrect Answers
A:This statement is true of Rightsizing, which addresses a monthly review finds development servers consume little of their allocated CPU and memory. It does not explain the particular role of Capital expenditure; Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption.
C:This statement is true of Variable costs, which addresses a retailer wants lower cloud expenses during months with fewer transactions. It does not explain the particular role of Capital expenditure; Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption.
D:This statement is true of License-included pricing, which addresses a team prefers a cloud software offering whose price includes the relevant software license. It does not explain the particular role of Capital expenditure; Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption.
Question 1123
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support infrastructure as code provisioning?
- AWS service APIs
- AWS SDKs
- AWS CloudFormation
- AWS CLI
Explanation
Correct Answer
C:AWS CloudFormation directly addresses this outcome. CloudFormation uses templates and stacks to create and manage supported AWS resources consistently. A common relevant example is: a cloud team must define a repeatable infrastructure configuration under version control.
Incorrect Answers
A:AWS service APIs instead focuses on a different requirement, such as a system needs a programmatic interface to request and manage AWS resources. AWS APIs enable programmatic service access; management consoles and SDKs are other ways to use such capabilities. It is not the primary match for the requirement described here: support infrastructure as code provisioning.
B:AWS SDKs instead focuses on a different requirement, such as a developer wants a Java application to interact with AWS services using language libraries. AWS SDKs provide language-specific APIs and tooling for integrating application software with AWS. It is not the primary match for the requirement described here: support infrastructure as code provisioning.
D:AWS CLI instead focuses on a different requirement, such as an operations engineer wants to run repeatable AWS service commands from a terminal script. The AWS CLI exposes AWS service operations through command-line commands suitable for controlled automation. It is not the primary match for the requirement described here: support infrastructure as code provisioning.
Question 1124
A research portal expects sustained growth from thousands to millions of visitors over several years. Which AWS service or cloud concept is the MOST direct match for this need?
- Global reach
- Elasticity
- Fault tolerance
- Scalability
Explanation
Correct Answer
D:Scalability fits the need because scalability is the ability to handle greater load by adding resources or increasing their capacity as an organization grows. The relevant capability or responsibility is: Increase a system's capacity to handle a larger ongoing workload.
Incorrect Answers
A:Global reach is associated with a different use case: a software provider wants to serve customers from multiple continents without building overseas data centers. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market. The question instead focuses on a research portal expects sustained growth from thousands to millions of visitors over several years; Scalability is the more direct match.
B: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 research portal expects sustained growth from thousands to millions of visitors over several years; Scalability is the more direct match.
C:Fault tolerance is associated with a different use case: a payment-processing workload must continue processing transactions when an individual component unexpectedly fails. Fault tolerance keeps service functioning when failures happen, often through replicated or redundant components. The question instead focuses on a research portal expects sustained growth from thousands to millions of visitors over several years; Scalability is the more direct match.
Question 1125
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: enable applicable data-at-rest encryption on storage services?
- Encryption at rest
- Amazon Macie
- AWS KMS
- AWS CloudHSM
Explanation
Correct Answer
A:Encryption at rest directly addresses this outcome. Encryption at rest protects stored data against certain exposure risks, not data traveling across the network. A common relevant example is: a business wants to protect stored information on storage volumes or objects.
Incorrect Answers
B: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: enable applicable data-at-rest encryption on storage services.
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: enable applicable data-at-rest encryption on storage services.
D:AWS CloudHSM hardware keys instead focuses on a different requirement, such as a company needs dedicated hardware security modules for particular cryptographic key requirements. CloudHSM provides customer-controlled HSM capacity for supported workloads requiring hardware-backed cryptographic operations. It is not the primary match for the requirement described here: enable applicable data-at-rest encryption on storage services.
Question 1126
Within the Security and Compliance domain, which business example MOST clearly illustrates Customer RDS data permissions, rather than a different AWS concept?
- A team accidentally publishes an S3 bucket containing internal reports
- An RDS database stores sensitive customer records and must restrict user privileges
- A company uses EC2 but asks who maintains the hardware supporting its virtual machines
- A technology leader compares the management obligations of EC2, RDS and Lambda
Explanation
Correct Answer
B:The decisive requirement is: The customer configures database users and permissions for its application data. This is the role of Customer RDS data permissions. Selecting a managed database does not transfer responsibility for customer identities and data authorization to AWS.
Incorrect Answers
A:This describes a scenario for Customer S3 bucket access: the customer must correct the bucket access policy and exposure settings. AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. It is not the most direct example of Customer RDS data permissions.
C:This describes a scenario for AWS EC2 host infrastructure: aWS maintains the physical host and underlying cloud virtualization infrastructure. AWS is responsible for facilities, physical servers and underlying cloud infrastructure for EC2. It is not the most direct example of Customer RDS data permissions.
D:This describes a scenario for Shared responsibility varies by service: 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. It is not the most direct example of Customer RDS data permissions.
Question 1127
A website needs inbound requests distributed among several healthy application targets. Which AWS service or cloud concept is the MOST direct match for this need?
- Amazon EKS
- Amazon ECS
- Elastic Load Balancing
- Storage-optimized EC2
Explanation
Correct Answer
C:Elastic Load Balancing fits the need because elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance. The relevant capability or responsibility is: Use Elastic Load Balancing to distribute incoming workload traffic.
Incorrect Answers
A:Amazon EKS is associated with a different use case: an organization wants managed Kubernetes control-plane capabilities for containerized workloads. EKS offers managed Kubernetes control-plane capabilities for applications using Kubernetes APIs. The question instead focuses on a website needs inbound requests distributed among several healthy application targets; Elastic Load Balancing is the more direct match.
B:Amazon ECS is associated with a different use case: an application team needs AWS-native orchestration of container workloads. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options. The question instead focuses on a website needs inbound requests distributed among several healthy application targets; Elastic Load Balancing is the more direct match.
D:Storage-optimized EC2 is associated with a different use case: an analytics node needs high local disk throughput for temporary data processing. Storage-optimized instance families are designed for high local storage I/O and throughput needs. The question instead focuses on a website needs inbound requests distributed among several healthy application targets; Elastic Load Balancing is the more direct match.
Question 1128
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: continuously improve operations and operational procedures?
- Automated operational response
- Security pillar
- Measure outcomes
- Operational Excellence pillar
Explanation
Correct Answer
D:Operational Excellence pillar directly addresses this outcome. The Operational Excellence pillar focuses on running and monitoring workloads effectively and improving operational processes. A common relevant example is: a team wants to improve routine operations through measurement, incident learning, and repeatable processes.
Incorrect Answers
A:Automated operational response instead focuses on a different requirement, such as operators repeatedly perform the same low-risk response to predictable workload events. Automating repeatable operations reduces manual error and supports dependable responses while human review remains appropriate for sensitive changes. It is not the primary match for the requirement described here: continuously improve operations and operational procedures.
B:Security pillar instead focuses on a different requirement, such as a business wants to protect data, identities, and systems while maintaining risk controls. The Security pillar addresses identity, detection, infrastructure and data protection in the AWS Well-Architected Framework. It is not the primary match for the requirement described here: continuously improve operations and operational procedures.
C:Measure outcomes instead focuses on a different requirement, such as a cloud team cannot tell whether a change improved customer-facing performance. The Well-Architected approach encourages observing real workload outcomes rather than relying only on resource existence. It is not the primary match for the requirement described here: continuously improve operations and operational procedures.
Question 1129
A project manager compares Global reach with other AWS concepts while considering this need: a software provider wants to serve customers from multiple continents without building overseas data centers. Which pairing assigns the responsibilities or benefits correctly?
- Global reach: deploy services geographically close to international users; High availability: keep the application accessible by using redundant resources and eliminating single points of failure
- Global reach: keep the application accessible by using redundant resources and eliminating single points of failure; High availability: deploy services geographically close to international users
- Global reach: provision capacity when requested rather than waiting for hardware ordering; On-demand provisioning: deploy services geographically close to international users
- Global reach: reduce routine infrastructure management by consuming a managed service; Managed service operations: deploy services geographically close to international users
Explanation
Correct Answer
A:The first pairing identifies Global reach with its actual role: deploy services geographically close to international users. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market. The comparison is valid because High availability instead addresses keep the application accessible by using redundant resources and eliminating single points of failure.
Incorrect Answers
B:The roles are swapped. High availability is associated with keep the application accessible by using redundant resources and eliminating single points of failure; Global reach instead has the role: Deploy services geographically close to international users. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.
C:The roles are swapped. On-demand provisioning is associated with provision capacity when requested rather than waiting for hardware ordering; Global reach instead has the role: Deploy services geographically close to international users. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.
D:The roles are swapped. Managed service operations is associated with reduce routine infrastructure management by consuming a managed service; Global reach instead has the role: Deploy services geographically close to international users. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.
Question 1130
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: revisit architecture decisions as requirements and capabilities change?
- Automated operational response
- Design for expected change
- Operational Excellence pillar
- Cost Optimization pillar
Explanation
Correct Answer
B:Design for expected change directly addresses this outcome. Cloud design principles favor adaptability and continual evaluation over treating an early configuration as permanently optimal. A common relevant example is: a company expects its cloud usage and business requirements to evolve frequently.
Incorrect Answers
A:Automated operational response instead focuses on a different requirement, such as operators repeatedly perform the same low-risk response to predictable workload events. Automating repeatable operations reduces manual error and supports dependable responses while human review remains appropriate for sensitive changes. It is not the primary match for the requirement described here: revisit architecture decisions as requirements and capabilities change.
C:Operational Excellence pillar instead focuses on a different requirement, such as a team wants to improve routine operations through measurement, incident learning, and repeatable processes. The Operational Excellence pillar focuses on running and monitoring workloads effectively and improving operational processes. It is not the primary match for the requirement described here: revisit architecture decisions as requirements and capabilities change.
D:Cost Optimization pillar instead focuses on a different requirement, such as a department wants to eliminate idle spending and understand the cost of delivering business value. Cost Optimization includes understanding expenditure, selecting cost-effective resources, and managing demand and supply. It is not the primary match for the requirement described here: revisit architecture decisions as requirements and capabilities change.
