Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 11
Question 100
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support eligible ephemeral EC2 local storage?
- Amazon EBS
- AWS Backup
- Amazon EFS
- EC2 instance store
Explanation
Correct Answer
D:EC2 instance store directly addresses this outcome. Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume. A common relevant example is: a rendering workload needs high-performance temporary local scratch data that may be lost with its instance.
Incorrect Answers
A:Amazon EBS block volumes instead focuses on a different requirement, such as a database server on EC2 needs persistent block storage beyond the life of one specific host. EBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration. It is not the primary match for the requirement described here: support eligible ephemeral EC2 local storage.
B:AWS Backup instead focuses on a different requirement, such as a company needs centralized policies and visibility across supported AWS resource backups. AWS Backup centralizes backup administration across supported resources; it is separate from normal object lifecycle transitions. It is not the primary match for the requirement described here: support eligible ephemeral EC2 local storage.
C:Amazon EFS shared files instead focuses on a different requirement, such as multiple Linux EC2 instances require a shared elastic file system supporting common file semantics. EFS is a managed elastic network file system for supported Linux workloads, unlike S3 object API storage. It is not the primary match for the requirement described here: support eligible ephemeral EC2 local storage.
Question 101
A stakeholder is considering Rehosting migration because a company wants to move an existing server-based application to AWS with minimal application changes. What is the MOST relevant capability or benefit?
- Move the existing workload largely as-is to cloud infrastructure
- Meet this requirement: an organization must transfer a very large volume of data from a remote site with insufficient network bandwidth
- Leave a selected workload in its existing environment for now
- Move compatible virtual machines or virtualized infrastructure with minimal change
Explanation
Correct Answer
A:Move the existing workload largely as-is to cloud infrastructure. Rehosting, often called lift and shift, relocates a workload without significant application redesign. The stated need is specifically a company wants to move an existing server-based application to AWS with minimal application changes.
Incorrect Answers
B:This outcome fits AWS Snow Family: AWS Snow devices support moving large datasets when transferring everything over a network is slow or constrained. The stakeholder requires the more specific capability provided by Rehosting migration, not that separate benefit.
C:This outcome fits Retaining a workload: Retaining is an intentional decision to defer migration when business or technical constraints make an immediate move inappropriate. The stakeholder requires the more specific capability provided by Rehosting migration, not that separate benefit.
D:This outcome fits Relocating a workload: Relocating retains much of the underlying virtualization model while shifting where it runs. The stakeholder requires the more specific capability provided by Rehosting migration, not that separate benefit.
Question 102
A solutions advisor wants to estimate charges for a proposed AWS environment before it is created. Which AWS service or cloud concept is the MOST direct match for this need?
- Cost allocation tags
- AWS Pricing Calculator
- AWS Billing console
- AWS Free Tier
Explanation
Correct Answer
B:AWS Pricing Calculator fits the need because pricing Calculator models estimated charges from selected assumptions rather than reading an existing account's actual spending. The relevant capability or responsibility is: Use AWS Pricing Calculator for planned service cost estimates.
Incorrect Answers
A:Cost allocation tags is associated with a different use case: a company wants to attribute AWS spending to department owners using approved resource labels. Cost allocation tags help group eligible charges by tagged resources after activation and appropriate billing data collection. The question instead focuses on a solutions advisor wants to estimate charges for a proposed AWS environment before it is created; AWS Pricing Calculator is the more direct match.
C:AWS Billing console is associated with a different use case: 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. The question instead focuses on a solutions advisor wants to estimate charges for a proposed AWS environment before it is created; AWS Pricing Calculator is the more direct match.
D:AWS Free Tier is associated with a different use case: 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. The question instead focuses on a solutions advisor wants to estimate charges for a proposed AWS environment before it is created; AWS Pricing Calculator is the more direct match.
Question 103
A learner is explaining Dedicated Hosts to colleagues facing this situation: an organization needs a physical host dedicated to its account for certain licensing or compliance needs. Which explanation is MOST accurate?
- Savings Plans provide discounts for covered usage in exchange for a one- or three-year commitment to an hourly spend amount.
- An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction.
- Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs.
- S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost.
Explanation
Correct Answer
C:Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs. The explanation directly connects Dedicated Hosts to use Dedicated Hosts when eligible licensing requires host visibility and control for the stated requirement.
Incorrect Answers
A:This statement is true of Savings Plans, which addresses a business expects steady eligible compute spending and can commit to a consistent hourly amount. It does not explain the particular role of Dedicated Hosts; Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs.
B:This statement is true of On-Demand Capacity Reservations, which addresses a business needs assurance that EC2 capacity will be available in a chosen Availability Zone for a planned event. It does not explain the particular role of Dedicated Hosts; Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs.
D:This statement is true of S3 storage-class pricing, which addresses an archive team needs to compare object storage costs between frequently accessed and rarely retrieved data. It does not explain the particular role of Dedicated Hosts; Dedicated Hosts supply dedicated EC2 physical server capacity with characteristics useful for supported bring-your-own-license needs.
Question 104
A project manager compares Performance Efficiency pillar with other AWS concepts while considering this need: a team compares computing approaches to meet response-time goals without unnecessary resources. Which pairing assigns the responsibilities or benefits correctly?
- Performance Efficiency pillar: use automation for routine, repeatable operational actions; Automated operational response: use computing resources efficiently as requirements change
- Performance Efficiency pillar: avoid unnecessary expense while delivering required outcomes; Cost Optimization pillar: use computing resources efficiently as requirements change
- Performance Efficiency pillar: continuously improve operations and operational procedures; Operational Excellence pillar: use computing resources efficiently as requirements change
- Performance Efficiency pillar: use computing resources efficiently as requirements change; Operational Excellence pillar: continuously improve operations and operational procedures
Explanation
Correct Answer
D:The first pairing identifies Performance Efficiency pillar with its actual role: use computing resources efficiently as requirements change. The Performance Efficiency pillar focuses on choosing and adapting resources to match workload performance needs. The comparison is valid because Operational Excellence pillar instead addresses continuously improve operations and operational procedures.
Incorrect Answers
A:The roles are swapped. Automated operational response is associated with use automation for routine, repeatable operational actions; Performance Efficiency pillar instead has the role: Use computing resources efficiently as requirements change. The Performance Efficiency pillar focuses on choosing and adapting resources to match workload performance needs.
B:The roles are swapped. Cost Optimization pillar is associated with avoid unnecessary expense while delivering required outcomes; Performance Efficiency pillar instead has the role: Use computing resources efficiently as requirements change. The Performance Efficiency pillar focuses on choosing and adapting resources to match workload performance needs.
C:The roles are swapped. Operational Excellence pillar is associated with continuously improve operations and operational procedures; Performance Efficiency pillar instead has the role: Use computing resources efficiently as requirements change. The Performance Efficiency pillar focuses on choosing and adapting resources to match workload performance needs.
Question 105
An operations team wants recommendations for AWS best practices in areas such as costs and security. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS Trusted Advisor
- AWS Support Center
- AWS Support plans
- AWS Health Dashboard
Explanation
Correct Answer
A:AWS Trusted Advisor fits the need because trusted Advisor provides advisory findings in supported categories; available checks and features depend on account arrangements. The relevant capability or responsibility is: Use AWS Trusted Advisor for available best-practice checks.
Incorrect Answers
B:AWS Support Center is associated with a different use case: a company needs to open and manage a support case through its applicable AWS plan. Support Center is the AWS interface for support cases and related help according to the account's plan. The question instead focuses on an operations team wants recommendations for AWS best practices in areas such as costs and security; AWS Trusted Advisor is the more direct match.
C:AWS Support plans is associated with a different use case: a business wants to compare the support response options included with different AWS support tiers. Support benefits and service-level commitments depend on the chosen plan and current AWS support terms. The question instead focuses on an operations team wants recommendations for AWS best practices in areas such as costs and security; AWS Trusted Advisor is the more direct match.
D:AWS Health Dashboard is associated with a different use case: a team wants to understand AWS service events that may affect its account or Region. AWS Health provides information about relevant service disruptions and scheduled changes; it is distinct from an application metric alarm. The question instead focuses on an operations team wants recommendations for AWS best practices in areas such as costs and security; AWS Trusted Advisor is the more direct match.
Question 106
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: recover from disruptions and perform the intended function consistently?
- Test recovery assumptions
- Reliability pillar
- Infrastructure changes as code
- Security pillar
Explanation
Correct Answer
B:Reliability pillar directly addresses this outcome. The Reliability pillar emphasizes recovery, distributed design, and meeting availability requirements. A common relevant example is: an application needs to recover predictably from failures and adapt when demand changes.
Incorrect Answers
A:Test recovery assumptions instead focuses on a different requirement, such as a service owner has a written recovery plan but does not know whether it would work in practice. Regular recovery testing reveals gaps in backup, dependency, and restoration plans before a real disruption. It is not the primary match for the requirement described here: recover from disruptions and perform the intended function consistently.
C:Infrastructure changes as code instead focuses on a different requirement, such as a team repeatedly creates similar environments and wants changes that can be reviewed and reproduced. Infrastructure as code reduces manual drift and supports consistent, reviewable infrastructure provisioning. It is not the primary match for the requirement described here: recover from disruptions and perform the intended function consistently.
D: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: recover from disruptions and perform the intended function consistently.
Question 107
A learner is explaining AWS physical data center security to colleagues facing this situation: an AWS customer asks who guards the buildings where AWS runs underlying server hardware. Which explanation is MOST accurate?
- AWS provides available Regions, while the customer chooses deployment locations to meet its legal and organizational obligations.
- 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.
- Even on a managed AWS service, customers remain responsible for authorizing who can access their data.
Explanation
Correct Answer
C:Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud. The explanation directly connects AWS physical data center security to aWS secures the physical facilities that host its cloud infrastructure for the stated requirement.
Incorrect Answers
A:This statement is true of Customer choice of AWS Region, which addresses a business contract requires some client records to remain in a specified geographic jurisdiction. It does not explain the particular role of AWS physical data center security; Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud.
B:This statement is true of Customer EC2 guest operating system, which addresses a business runs its own Linux installation on an Amazon EC2 virtual machine. It does not explain the particular role of AWS physical data center security; Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud.
D:This statement is true of Customer IAM permissions, which addresses an organization must decide which employees can read an S3 bucket in its AWS account. It does not explain the particular role of AWS physical data center security; Physical facility access controls and provider-owned hardware protection fall under AWS security of the cloud.
Question 108
A small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself. Which AWS service or cloud concept is the MOST direct match for this need?
- Total cost of ownership
- License-included pricing
- Variable costs
- Economies of scale
Explanation
Correct Answer
D:Economies of scale fits the need because large cloud providers spread infrastructure costs across many customers and workloads. The relevant capability or responsibility is: Benefit from aggregate cloud-provider scale and procurement efficiency.
Incorrect Answers
A:Total cost of ownership is associated with a different use case: a finance director compares AWS migration with building another private data center. Total cost of ownership considers direct and indirect costs, not only an instance hourly price. The question instead focuses on a small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself; Economies of scale is the more direct match.
B:License-included pricing is associated with a different use case: a team prefers a cloud software offering whose price includes the relevant software license. License-included pricing is distinct from providing a separately acquired customer license under BYOL. The question instead focuses on a small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself; Economies of scale is the more direct match.
C:Variable costs is associated with a different use case: a retailer wants lower cloud expenses during months with fewer transactions. Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level. The question instead focuses on a small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself; Economies of scale is the more direct match.
Question 109
Within the Security and Compliance domain, which business example MOST clearly illustrates Shared responsibility varies by service, rather than a different AWS concept?
- A technology leader compares the management obligations of EC2, RDS and Lambda
- A company uses EC2 but asks who maintains the hardware supporting its virtual machines
- An organization must decide which employees can read an S3 bucket in its AWS account
- A business runs its own Linux installation on an Amazon EC2 virtual machine
Explanation
Correct Answer
A:The decisive requirement is: Customer operational responsibilities generally decrease as more service layers become AWS-managed. This is the role of Shared responsibility varies by service. Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda.
Incorrect Answers
B: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 Shared responsibility varies by service.
C:This describes a scenario for Customer IAM permissions: 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. It is not the most direct example of Shared responsibility varies by service.
D:This describes a scenario for Customer EC2 guest operating system: 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. It is not the most direct example of Shared responsibility varies by service.
Question 110
A project manager compares Edge content delivery with other AWS concepts while considering this need: a media company serves static images to viewers in many countries and wants them delivered near viewers. Which pairing assigns the responsibilities or benefits correctly?
- Edge content delivery: experiment and deliver changes rapidly using on-demand resources; Agility: cache frequently requested content at locations closer to end users
- Edge content delivery: cache frequently requested content at locations closer to end users; Agility: experiment and deliver changes rapidly using on-demand resources
- Edge content delivery: deploy services geographically close to international users; Global reach: cache frequently requested content at locations closer to end users
- Edge content delivery: protect stored objects against underlying component failures; Storage durability: cache frequently requested content at locations closer to end users
Explanation
Correct Answer
B:The first pairing identifies Edge content delivery with its actual role: cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users. The comparison is valid because Agility instead addresses experiment and deliver changes rapidly using on-demand resources.
Incorrect Answers
A:The roles are swapped. Agility is associated with experiment and deliver changes rapidly using on-demand resources; Edge content delivery instead has the role: Cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users.
C:The roles are swapped. Global reach is associated with deploy services geographically close to international users; Edge content delivery instead has the role: Cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users.
D:The roles are swapped. Storage durability is associated with protect stored objects against underlying component failures; Edge content delivery instead has the role: Cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users.
