Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 72
Question 710
A Lambda function processes user data using application code written by a development team. Which AWS service or cloud concept is the MOST direct match for this need?
- Customer EC2 guest operating system
- Customer Lambda function code
- Customer S3 bucket access
- Customer data classification
Explanation
Correct Answer
B:Customer Lambda function code fits the need because serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling. The relevant capability or responsibility is: The customer is responsible for the function code and its business logic.
Incorrect Answers
A:Customer EC2 guest operating system is associated with a different use case: a business runs its own Linux installation on an Amazon EC2 virtual machine. For EC2 the customer manages the guest OS, applications and their configuration while AWS manages underlying physical hosts. The question instead focuses on a Lambda function processes user data using application code written by a development team; Customer Lambda function code is the more direct match.
C:Customer S3 bucket access is associated with a different use case: a team accidentally publishes an S3 bucket containing internal reports. AWS operates the S3 storage infrastructure, but customers configure authorized access to their buckets and objects. The question instead focuses on a Lambda function processes user data using application code written by a development team; Customer Lambda function code is the more direct match.
D:Customer data classification is associated with a different use case: 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. The question instead focuses on a Lambda function processes user data using application code written by a development team; Customer Lambda function code is the more direct match.
Question 711
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: keep the application accessible by using redundant resources and eliminating single points of failure?
- On-demand provisioning
- Pay-as-you-go consumption
- High availability
- Reduced infrastructure maintenance
Explanation
Correct Answer
C:High availability directly addresses this outcome. High availability focuses on minimizing service interruptions through redundancy and service continuity. A common relevant example is: a hospital booking service must remain accessible even when one hosting location becomes unavailable.
Incorrect Answers
A:On-demand provisioning instead focuses on a different requirement, such as a testing team needs temporary computing capacity immediately for a newly approved project. AWS self-service resource provisioning reduces procurement lead time for many workloads. It is not the primary match for the requirement described here: keep the application accessible by using redundant resources and eliminating single points of failure.
B:Pay-as-you-go consumption instead focuses on a different requirement, such as a seasonal nonprofit wants computing only during a two-week annual campaign. Usage-based cloud charging can reduce upfront investment and better match cost to periods of actual consumption. It is not the primary match for the requirement described here: keep the application accessible by using redundant resources and eliminating single points of failure.
D:Reduced infrastructure maintenance instead focuses on a different requirement, such as a small team prefers to focus on application features instead of replacing failed server hardware. AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks. It is not the primary match for the requirement described here: keep the application accessible by using redundant resources and eliminating single points of failure.
Question 712
A project manager compares AWS data transfer charges with other AWS concepts while considering this need: a company compares incoming internet traffic with traffic sent from AWS to external users. Which pairing assigns the responsibilities or benefits correctly?
- AWS data transfer charges: compare storage duration, retrieval charges and access characteristics of S3 classes; Amazon S3 storage class selection: account for service- and route-dependent data transfer pricing
- AWS data transfer charges: trade some flexibility for eligible discounted capacity or spending commitments; Compute commitment flexibility: account for service- and route-dependent data transfer pricing
- AWS data transfer charges: meet this requirement: a research team runs flexible batch processing jobs that can tolerate interruption; EC2 Spot Instances: account for service- and route-dependent data transfer pricing
- AWS data transfer charges: account for service- and route-dependent data transfer pricing; Compute commitment flexibility: trade some flexibility for eligible discounted capacity or spending commitments
Explanation
Correct Answer
D:The first pairing identifies AWS data transfer charges with its actual role: account for service- and route-dependent data transfer pricing. Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path. The comparison is valid because Compute commitment flexibility instead addresses trade some flexibility for eligible discounted capacity or spending commitments.
Incorrect Answers
A:The roles are swapped. Amazon S3 storage class selection is associated with compare storage duration, retrieval charges and access characteristics of S3 classes; AWS data transfer charges instead has the role: Account for service- and route-dependent data transfer pricing.
