Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 13
Question 120
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: maintain operation despite certain component failures?
- Storage durability
- Rapid experimentation
- High availability
- Fault tolerance
Explanation
Correct Answer
D:Fault tolerance directly addresses this outcome. Fault tolerance keeps service functioning when failures happen, often through replicated or redundant components. A common relevant example is: a payment-processing workload must continue processing transactions when an individual component unexpectedly fails.
Incorrect Answers
A:Storage durability instead focuses on a different requirement, such as a photo service needs stored customer pictures to remain intact despite individual storage hardware failures. Durability describes the likelihood that stored data remains intact; it is different from immediate service accessibility. It is not the primary match for the requirement described here: maintain operation despite certain component failures.
B:Rapid experimentation instead focuses on a different requirement, such as a product group wants to run several short-lived proofs of concept at low initial commitment. On-demand cloud environments make experiments easier to start and stop as new ideas are evaluated. It is not the primary match for the requirement described here: maintain operation despite certain component failures.
C:High availability instead focuses on a different requirement, such as a hospital booking service must remain accessible even when one hosting location becomes unavailable. High availability focuses on minimizing service interruptions through redundancy and service continuity. It is not the primary match for the requirement described here: maintain operation despite certain component failures.
Question 121
A stakeholder is considering Multiple AWS Regions because a business needs a disaster recovery location outside the primary Region. What is the MOST relevant capability or benefit?
- Provide part of a multi-Region continuity plan
- Deliver cached web content nearer to globally distributed users
- Select a geographic cloud infrastructure location
- Distribute components across isolated locations inside one geographic Region
Explanation
Correct Answer
A:Use a separate AWS Region as part of a multi-Region continuity plan. Deploying across Regions can address geographic disruptions, customer latency and residency objectives at higher complexity. The stated need is specifically a business needs a disaster recovery location outside the primary Region.
Incorrect Answers
B:This outcome fits Amazon CloudFront global caching: CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers. The stakeholder requires the more specific capability provided by Multiple AWS Regions, not that separate benefit.
C:This outcome fits AWS Region: A Region is a geographically separate area containing multiple Availability Zones; customers select deployment Regions. The stakeholder requires the more specific capability provided by Multiple AWS Regions, not that separate benefit.
D:This outcome fits Availability Zone: Availability Zones are distinct locations within a Region designed to reduce shared failure risks. The stakeholder requires the more specific capability provided by Multiple AWS Regions, not that separate benefit.
Question 122
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates AWS Support plans, rather than a different AWS concept?
- A developer wants to ask a public technical question and learn from AWS community answers
- A business wants to compare the support response options included with different AWS support tiers
- A team wants to understand AWS service events that may affect its account or Region
- An operations team wants recommendations for AWS best practices in areas such as costs and security
Explanation
Correct Answer
B:The decisive requirement is: Review current AWS Support plans for eligible response and contact options. This is the role of AWS Support plans. Support benefits and service-level commitments depend on the chosen plan and current AWS support terms.
Incorrect Answers
A:This describes a scenario for AWS re:Post: use AWS re:Post for community-based AWS technical discussions. re:Post provides community questions and answers rather than guaranteed contractual support response times. It is not the most direct example of AWS Support plans.
C:This describes a scenario for AWS Health Dashboard: review AWS Health Dashboard for service and account events. AWS Health provides information about relevant service disruptions and scheduled changes; it is distinct from an application metric alarm. It is not the most direct example of AWS Support plans.
D:This describes a scenario for AWS Trusted Advisor: use AWS Trusted Advisor for available best-practice checks. Trusted Advisor provides advisory findings in supported categories; available checks and features depend on account arrangements. It is not the most direct example of AWS Support plans.
Question 123
An administrator wants continuous assessments of supported workloads for software vulnerabilities. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS CloudTrail
- Amazon GuardDuty
- Amazon Inspector
- Defense in depth
Explanation
Correct Answer
C:Amazon Inspector fits the need because inspector identifies package and supported workload vulnerabilities; it is not a replacement for data classification. The relevant capability or responsibility is: Use Amazon Inspector for vulnerability management findings.
Incorrect Answers
A:AWS CloudTrail API auditing is associated with a different use case: a security analyst needs to see which principal made an AWS control-plane API call. CloudTrail helps audit actions performed through the console, SDK and API; it differs from performance metrics. The question instead focuses on an administrator wants continuous assessments of supported workloads for software vulnerabilities; Amazon Inspector is the more direct match.
B:Amazon GuardDuty threat detection is associated with a different use case: a security team wants managed detection of suspicious activity from AWS account and workload signals. GuardDuty analyzes signals for suspicious or malicious behavior rather than acting as a general-purpose firewall. The question instead focuses on an administrator wants continuous assessments of supported workloads for software vulnerabilities; Amazon Inspector is the more direct match.
D:Defense in depth is associated with a different use case: 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. The question instead focuses on an administrator wants continuous assessments of supported workloads for software vulnerabilities; Amazon Inspector is the more direct match.
Question 124
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates AWS Budgets, rather than a different AWS concept?
- A company wants to attribute AWS spending to department owners using approved resource labels
- A solutions advisor wants to estimate charges for a proposed AWS environment before it is created
- An organization needs granular line-item records of AWS charges for internal analytics
- A project manager wants an alert when forecast monthly cloud spending will exceed a set threshold
Explanation
Correct Answer
D:The decisive requirement is: Use AWS Budgets to track spending or usage against defined budget thresholds. This is the role of AWS Budgets. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor.
Incorrect Answers
A:This describes a scenario for Cost allocation tags: use enabled cost allocation tags for supported billing attribution. Cost allocation tags help group eligible charges by tagged resources after activation and appropriate billing data collection. It is not the most direct example of AWS Budgets.
B:This describes a scenario for AWS Pricing Calculator: use AWS Pricing Calculator for planned service cost estimates. Pricing Calculator models estimated charges from selected assumptions rather than reading an existing account's actual spending. It is not the most direct example of AWS Budgets.
C:This describes a scenario for AWS Cost and Usage Report: use AWS Cost and Usage Reports for detailed cost and consumption data. Cost and Usage Reports provide detailed charge records suitable for custom analysis rather than just high-level charts. It is not the most direct example of AWS Budgets.
Question 125
A stakeholder is considering Amazon EFS because multiple Linux EC2 instances require a shared elastic file system supporting common file semantics. What is the MOST relevant capability or benefit?
- Support managed shared file storage
- Support persistent EC2 block storage
- Optimize eligible data with changing access patterns
- Support scalable object storage
Explanation
Correct Answer
A:Use Amazon Elastic File System for managed shared file storage. EFS is a managed elastic network file system for supported Linux workloads, unlike S3 object API storage. The stated need is specifically multiple Linux EC2 instances require a shared elastic file system supporting common file semantics.
Incorrect Answers
B:This outcome fits Amazon EBS block volumes: EBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration. The stakeholder requires the more specific capability provided by Amazon EFS, not that separate benefit.
C:This outcome fits S3 Intelligent-Tiering: Intelligent-Tiering moves eligible objects among access tiers based on usage, with monitoring and other class terms. The stakeholder requires the more specific capability provided by Amazon EFS, not that separate benefit.
D:This outcome fits Amazon S3 object storage: S3 stores data as objects in buckets; it is not an attachable EC2 block device or shared POSIX file system. The stakeholder requires the more specific capability provided by Amazon EFS, not that separate benefit.
Question 126
Within the Billing, Pricing, and Support domain, which business example MOST clearly illustrates AWS Trusted Advisor, rather than a different AWS concept?
- A company needs help finding qualified AWS consulting or software partners
- An operations team wants recommendations for AWS best practices in areas such as costs and security
- A developer wants to ask a public technical question and learn from AWS community answers
- A business wants to compare the support response options included with different AWS support tiers
Explanation
Correct Answer
B:The decisive requirement is: Use AWS Trusted Advisor for available best-practice checks. This is the role of AWS Trusted Advisor. Trusted Advisor provides advisory findings in supported categories; available checks and features depend on account arrangements.
Incorrect Answers
A:This describes a scenario for AWS Partner Network: use AWS Partner Network resources to identify AWS partners and offerings. APN connects customers with AWS partners, such as system integrators and independent software vendors. It is not the most direct example of AWS Trusted Advisor.
C:This describes a scenario for AWS re:Post: use AWS re:Post for community-based AWS technical discussions. re:Post provides community questions and answers rather than guaranteed contractual support response times. It is not the most direct example of AWS Trusted Advisor.
D:This describes a scenario for AWS Support plans: 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. It is not the most direct example of AWS Trusted Advisor.
Question 127
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: the customer selects where to deploy and store its workloads to meet residency rules?
- Customer data classification
- Customer Lambda function code
- Customer choice of AWS Region
- Customer RDS data permissions
Explanation
Correct Answer
C:Customer choice of AWS Region directly addresses this outcome. AWS provides available Regions, while the customer chooses deployment locations to meet its legal and organizational obligations. A common relevant example is: a business contract requires some client records to remain in a specified geographic jurisdiction.
Incorrect Answers
A:Customer data classification instead focuses on a different requirement, such as a regulated company must identify which of its uploaded records contain sensitive personal information. AWS cannot determine the business sensitivity of customer content; data classification and applicable handling policies belong to the customer. It is not the primary match for the requirement described here: the customer selects where to deploy and store its workloads to meet residency rules.
B:Customer Lambda function code instead focuses on a different requirement, such as a Lambda function processes user data using application code written by a development team. Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. It is not the primary match for the requirement described here: the customer selects where to deploy and store its workloads to meet residency rules.
D:Customer RDS data permissions instead focuses on a different requirement, such as an RDS database stores sensitive customer records and must restrict user privileges. Selecting a managed database does not transfer responsibility for customer identities and data authorization to AWS. It is not the primary match for the requirement described here: the customer selects where to deploy and store its workloads to meet residency rules.
Question 128
Within the Cloud Concepts domain, which business example MOST clearly illustrates Rightsizing, rather than a different AWS concept?
- A small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself
- A team prefers a cloud software offering whose price includes the relevant software license
- A company buys servers and pays the purchase cost before those servers are used
- A monthly review finds development servers consume little of their allocated CPU and memory
Explanation
Correct Answer
D:The decisive requirement is: Choose resource sizes appropriate for actual workload utilization. This is the role of Rightsizing. Rightsizing replaces persistently oversized resources with suitable capacities to improve cost efficiency.
Incorrect Answers
A:This describes a scenario for Economies of scale: benefit from aggregate cloud-provider scale and procurement efficiency. Large cloud providers spread infrastructure costs across many customers and workloads. It is not the most direct example of Rightsizing.
B:This describes a scenario for License-included pricing: use a service price that bundles eligible software licensing. License-included pricing is distinct from providing a separately acquired customer license under BYOL. It is not the most direct example of Rightsizing.
C:This describes a scenario for Capital expenditure: classify upfront infrastructure equipment purchases as capital spending. Owning servers typically requires an upfront capital investment, unlike metered cloud resource consumption. It is not the most direct example of Rightsizing.
Question 129
A learner is explaining Bring Your Own License to colleagues facing this situation: a company has eligible existing software licenses that might be usable on a cloud host. Which explanation is MOST accurate?
- BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied.
- Variable cost follows utilization or usage rather than remaining fixed at a pre-purchased capacity level.
- Large cloud providers spread infrastructure costs across many customers and workloads.
- Automation can reduce manual effort and mistakes while making temporary resources easier to retire.
Explanation
Correct Answer
A:BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied. The explanation directly connects Bring Your Own License to evaluate use of qualifying existing software licenses subject to vendor and AWS terms for the stated requirement.
Incorrect Answers
B: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 Bring Your Own License; BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied.
C:This statement is true of Economies of scale, which addresses a small organization benefits from AWS data-center purchasing power even though it cannot operate a massive facility itself. It does not explain the particular role of Bring Your Own License; BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied.
D:This statement is true of Automation savings, which addresses a department repeatedly creates and deletes temporary test environments by hand. It does not explain the particular role of Bring Your Own License; BYOL may reduce duplicate license purchases when specific licensing rules and deployment requirements are satisfied.
Question 130
A company wants a centralized bill and eligible aggregated charges from multiple AWS accounts. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS Cost Explorer
- Consolidated billing
- Cost allocation tags
- AWS Budgets
Explanation
Correct Answer
B:Consolidated billing fits the need because consolidated billing combines eligible charges and payment across AWS Organizations accounts while accounts remain logically distinct. The relevant capability or responsibility is: Use AWS Organizations consolidated billing across eligible member accounts.
Incorrect Answers
A:AWS Cost Explorer is associated with a different use case: a finance analyst wants to see past AWS spending trends by service and forecast likely future cost. Cost Explorer offers interactive cost analysis and forecasting over supported billing data. The question instead focuses on a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts; Consolidated billing is the more direct match.
C: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 company wants a centralized bill and eligible aggregated charges from multiple AWS accounts; Consolidated billing is the more direct match.
D:AWS Budgets is associated with a different use case: a project manager wants an alert when forecast monthly cloud spending will exceed a set threshold. Budgets supports cost and usage alerts relative to planned thresholds; it is distinct from an invoice payment processor. The question instead focuses on a company wants a centralized bill and eligible aggregated charges from multiple AWS accounts; Consolidated billing is the more direct match.
