Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 93

Question 920

A company places two redundant application servers in one Availability Zone and calls that zone fault tolerance. Which continuing control BEST supports this AWS approach?

  1. Recheck regional service support during architecture updates.
  2. Use multi-Region planning only when its different failure scope is needed.
  3. Validate service placement rather than substituting edge points for Regions.
  4. Inventory shared storage and networking dependencies by AZ.

Explanation

Correct Answer

D:

Inventory shared storage and networking dependencies by AZ. This continuing control fits because Multiple machines inside one AZ can still share the same zone failure domain. The associated appropriate response is: Use more than one AZ when the business requires protection from an AZ outage. An observable check is: A simulated AZ outage leaves at least one healthy instance in another AZ.

Incorrect Answers

A:

AWS services and features are not automatically supported in every Region. In this question, however, multiple machines inside one AZ can still share the same zone failure domain. The answer that meets the requirement is: Inventory shared storage and networking dependencies by AZ.

B:

A Region contains multiple AZs and provides a geographic operating boundary. In this question, however, multiple machines inside one AZ can still share the same zone failure domain. The answer that meets the requirement is: Inventory shared storage and networking dependencies by AZ.

C:

Edge locations provide selected network and caching functions rather than every regional service. In this question, however, multiple machines inside one AZ can still share the same zone failure domain. The answer that meets the requirement is: Inventory shared storage and networking dependencies by AZ.

Question 921

A team treats the phrase shared responsibility as meaning every task is done equally by AWS and the customer. Which ongoing practice BEST sustains the intended result?

  1. Revisit assignments after migrating from self-managed to managed services.
  2. Document retained schema, account, data and configuration duties.
  3. Review data categories and entitlements as workloads evolve.
  4. Maintain image patching and IAM checks for each Fargate task.

Explanation

Correct Answer

A:

Revisit assignments after migrating from self-managed to managed services. This continuing control fits because Responsibility is divided by layer and service, not split equally for every setting. The associated appropriate response is: Assign each control based on service type and what AWS or the customer actually configures. An observable check is: A control matrix names a clear owner for host, application, identity and data controls.

Incorrect Answers

B:

Managed RDS removes routine infrastructure and database-engine platform tasks from the customer's responsibility, subject to service features. In this question, however, responsibility is divided by layer and service, not split equally for every setting. The answer that meets the requirement is: Revisit assignments after migrating from self-managed to managed services.

C:

AWS infrastructure protection does not determine the customer's business and regulatory data handling rules. In this question, however, responsibility is divided by layer and service, not split equally for every setting. The answer that meets the requirement is: Revisit assignments after migrating from self-managed to managed services.

D:

Fargate abstracts server provisioning, but application images, secrets and permissions remain customer-controlled. In this question, however, responsibility is divided by layer and service, not split equally for every setting. The answer that meets the requirement is: Revisit assignments after migrating from self-managed to managed services.

Question 922

An analyst assumes all inbound and outbound Internet data transfer on AWS is free. What follow-up practice BEST maintains the desired outcome?

  1. Review BYOL entitlement and host capacity before purchasing.
  2. Model large transfers before selecting data placement and recovery design.
  3. Review scope, family and term before making an RI commitment.
  4. Separate capacity assurance decisions from pricing-discount commitments.

Explanation

Correct Answer

B:

Model large transfers before selecting data placement and recovery design. This continuing control fits because Data transfer in and out and between locations can have different charging rules. The associated appropriate response is: Review applicable data transfer direction, Region and network path pricing. An observable check is: The estimate includes relevant outbound and inter-Region transfer charges.

Incorrect Answers

A:

Dedicated Hosts provide physical server placement controls for eligible licensing requirements. In this question, however, data transfer in and out and between locations can have different charging rules. The answer that meets the requirement is: Model large transfers before selecting data placement and recovery design.

C:

Reserved Instance pricing can provide a commitment-based discount for qualifying instance usage. In this question, however, data transfer in and out and between locations can have different charging rules. The answer that meets the requirement is: Model large transfers before selecting data placement and recovery design.

D:

Capacity Reservations reserve supported instance capacity without being equivalent to an RI discount. In this question, however, data transfer in and out and between locations can have different charging rules. The answer that meets the requirement is: Model large transfers before selecting data placement and recovery design.

Question 923

A shopping-cart store needs very low-latency key-value access without traditional relational joins. Which precaution would MOST reduce the chance of the problem returning?

  1. Validate access patterns before committing to a database model.
  2. Keep schema design and data-access policy under customer review.
  3. Design partition keys and capacity around actual access patterns.
  4. Design cache expiry and invalidation with application owners.

Explanation

Correct Answer

C:

Design partition keys and capacity around actual access patterns. This continuing control fits because DynamoDB is a managed NoSQL service, not a general relational SQL join engine. The associated appropriate response is: Choose Amazon DynamoDB for a suitable managed NoSQL key-value workload. An observable check is: The tested key lookups and updates meet the application's access needs.

Incorrect Answers

A:

Managed NoSQL models can match simple key-oriented workloads without relational table joins. In this question, however, dynamoDB is a managed NoSQL service, not a general relational SQL join engine. The answer that meets the requirement is: Design partition keys and capacity around actual access patterns.

B:

RDS manages significant database platform operations while preserving relational SQL models. In this question, however, dynamoDB is a managed NoSQL service, not a general relational SQL join engine. The answer that meets the requirement is: Design partition keys and capacity around actual access patterns.

D:

ElastiCache keeps frequently accessed data in memory rather than acting as the system of record for all database history. In this question, however, dynamoDB is a managed NoSQL service, not a general relational SQL join engine. The answer that meets the requirement is: Design partition keys and capacity around actual access patterns.

Question 924

A legacy monolith cannot scale independently and the company plans to rebuild it around cloud-native services. What follow-up practice BEST maintains the desired outcome?

  1. Keep an inventory of approved application-retirement decisions.
  2. Monitor replication lag and verify application compatibility separately.
  3. Test driver and engine differences before cutover.
  4. Estimate redesign risk and test behavior before decommissioning the original system.

Explanation

Correct Answer

D:

Estimate redesign risk and test behavior before decommissioning the original system. This continuing control fits because Refactoring changes application architecture to obtain new capabilities rather than simply changing the hosting location. The associated appropriate response is: Classify the major redesign as refactoring or rearchitecting. An observable check is: Independent components can scale and be released through the intended interfaces.

Incorrect Answers

A:

Retiring avoids moving and operating systems with no continuing business value. In this question, however, refactoring changes application architecture to obtain new capabilities rather than simply changing the hosting location. The answer that meets the requirement is: Estimate redesign risk and test behavior before decommissioning the original system.

B:

DMS can capture supported source changes while initial data copies complete. In this question, however, refactoring changes application architecture to obtain new capabilities rather than simply changing the hosting location. The answer that meets the requirement is: Estimate redesign risk and test behavior before decommissioning the original system.

C:

Replatforming changes selected infrastructure or platform components without fully reinventing the application. In this question, however, refactoring changes application architecture to obtain new capabilities rather than simply changing the hosting location. The answer that meets the requirement is: Estimate redesign risk and test behavior before decommissioning the original system.

Question 925

An organization wants one view of spending across member accounts while retaining independent technical access boundaries. Which ongoing practice BEST sustains the intended result?

  1. Maintain separate account-level security controls despite shared billing.
  2. Enforce tagging standards and audit untagged resources.
  3. Review charge allocation and tag coverage each month.
  4. Review spending changes regularly rather than relying only on invoices.

Explanation

Correct Answer

A:

Maintain separate account-level security controls despite shared billing. This continuing control fits because Consolidated billing joins financial reporting while member AWS accounts remain separate administrative boundaries. The associated appropriate response is: Use Organizations consolidated billing without assuming accounts merge operationally. An observable check is: The management account sees member charges but each member retains its defined IAM resources.

Incorrect Answers

B:

Cost allocation tags help attribute tagged resource charges to business dimensions. In this question, however, consolidated billing joins financial reporting while member AWS accounts remain separate administrative boundaries. The answer that meets the requirement is: Maintain separate account-level security controls despite shared billing.

C:

Unclassified shared costs cannot reliably be assigned to each business workload. In this question, however, consolidated billing joins financial reporting while member AWS accounts remain separate administrative boundaries. The answer that meets the requirement is: Maintain separate account-level security controls despite shared billing.

D:

Cost Explorer supports cost visualization and analysis of usage trends. In this question, however, consolidated billing joins financial reporting while member AWS accounts remain separate administrative boundaries. The answer that meets the requirement is: Maintain separate account-level security controls despite shared billing.

Question 926

A regulated customer needs copies of AWS assurance reports and certifications for auditors. Which precaution would MOST reduce the chance of the problem returning?

  1. Establish response ownership for threat findings and maintain coverage.
  2. Verify the report's coverage dates and services before relying on it.
  3. Triage and patch findings according to business risk.
  4. Enforce approved HTTPS settings and certificate renewal monitoring.

Explanation

Correct Answer

B:

Verify the report's coverage dates and services before relying on it. This continuing control fits because AWS Artifact provides on-demand access to applicable AWS compliance reports and agreements. The associated appropriate response is: Retrieve eligible compliance documents through AWS Artifact. An observable check is: The auditor obtains the required report subject to permitted access and scope.

Incorrect Answers

A:

GuardDuty analyzes sources such as AWS activity and network telemetry to identify suspicious behavior. In this question, however, aWS Artifact provides on-demand access to applicable AWS compliance reports and agreements. The answer that meets the requirement is: Verify the report's coverage dates and services before relying on it.

C:

Inspector evaluates software vulnerabilities and exposure; it is not an API audit history service. In this question, however, aWS Artifact provides on-demand access to applicable AWS compliance reports and agreements. The answer that meets the requirement is: Verify the report's coverage dates and services before relying on it.

D:

Encryption at rest and encryption in transit protect data in different states. In this question, however, aWS Artifact provides on-demand access to applicable AWS compliance reports and agreements. The answer that meets the requirement is: Verify the report's coverage dates and services before relying on it.

Question 927

A project funds two unused disaster-recovery sites even though its recovery objective allows a slower restart. Which precaution would MOST reduce the chance of the problem returning?

  1. Recheck vendor license restrictions before migrations.
  2. Budget for remaining configuration and application ownership.
  3. Reassess recovery economics when business criticality changes.
  4. Set cost alerts and assign experiment ownership.

Explanation

Correct Answer

C:

Reassess recovery economics when business criticality changes. This continuing control fits because Always-on standby resources may cost more than the business benefit warrants. The associated appropriate response is: Choose a recovery approach proportionate to the documented RTO and RPO. An observable check is: A recovery cost comparison includes tested restore duration and data-loss tolerance.

Incorrect Answers

A:

BYOL and included licensing have different eligibility, usage and financial assumptions. In this question, however, always-on standby resources may cost more than the business benefit warrants. The answer that meets the requirement is: Reassess recovery economics when business criticality changes.

B:

Managed offerings can shift platform patching and infrastructure tasks from the customer. In this question, however, always-on standby resources may cost more than the business benefit warrants. The answer that meets the requirement is: Reassess recovery economics when business criticality changes.

D:

Variable consumption lets the company limit exposure while evaluating uncertain demand. In this question, however, always-on standby resources may cost more than the business benefit warrants. The answer that meets the requirement is: Reassess recovery economics when business criticality changes.

Question 928

An in-memory analytic process frequently runs out of RAM while CPU remains underused. Which continuing control BEST supports this AWS approach?

  1. Plan patching and instance sizing as customer responsibilities.
  2. Confirm framework compatibility and utilization before purchasing capacity.
  3. Control container image versions and resource allocations.
  4. Monitor resident memory and rightsize using workload peaks.

Explanation

Correct Answer

D:

Monitor resident memory and rightsize using workload peaks. This continuing control fits because Memory-optimized families provide higher memory resources for memory-bound applications. The associated appropriate response is: Evaluate memory-optimized EC2 instances for the workload. An observable check is: A representative dataset fits memory and processing completes without repeated swapping.

Incorrect Answers

A:

EC2 provides configurable server compute where customers manage guest software. In this question, however, memory-optimized families provide higher memory resources for memory-bound applications. The answer that meets the requirement is: Monitor resident memory and rightsize using workload peaks.

B:

In this question, however, memory-optimized families provide higher memory resources for memory-bound applications. The answer that meets the requirement is: Monitor resident memory and rightsize using workload peaks.

Question 929

A data lake team needs to catalog datasets and run managed data preparation jobs. Which precaution would MOST reduce the chance of the problem returning?

  1. Version transformations and review job access to data.
  2. Monitor intent accuracy and data privacy.
  3. Monitor query scan volume and govern dataset access.
  4. Review connector security and indexed content permissions.

Explanation

Correct Answer

A:

Version transformations and review job access to data. This continuing control fits because Glue provides cataloging and ETL-related services rather than a dashboard visualization product. The associated appropriate response is: Use AWS Glue for supported data integration and catalog use cases. An observable check is: A test job transforms source data and its schema is discoverable through the catalog.

Incorrect Answers

B:

Lex supports speech and language understanding for conversational applications. In this question, however, glue provides cataloging and ETL-related services rather than a dashboard visualization product. The answer that meets the requirement is: Version transformations and review job access to data.

The answer that meets the requirement is: Version transformations and review job access to data.

D:

Kendra provides intelligent search and ranking across configured content sources. In this question, however, glue provides cataloging and ETL-related services rather than a dashboard visualization product. The answer that meets the requirement is: Version transformations and review job access to data.

Question 930

An enterprise needs a business-continuity option for a regional natural disaster. Which ongoing practice BEST sustains the intended result?

  1. Include residency review in the regional launch checklist.
  2. Rehearse recovery and verify data replication rather than equating backups with instant failover.
  3. Document retained customer duties even for managed services.
  4. Review regional dependencies and cross-Region data-transfer requirements.

Explanation

Correct Answer

B:

Rehearse recovery and verify data replication rather than equating backups with instant failover. This continuing control fits because Separate Regions offer distinct geographic failure domains beyond one Region's AZs. The associated appropriate response is: Consider an appropriate multi-Region disaster-recovery approach for the business RTO and RPO. An observable check is: A documented regional failover exercise meets recovery time and recovery point objectives.

Incorrect Answers

A:

Geographical reach does not override legal or contractual data-location requirements. In this question, however, separate Regions offer distinct geographic failure domains beyond one Region's AZs. The answer that meets the requirement is: Rehearse recovery and verify data replication rather than equating backups with instant failover.

C:

A managed service transfers specific infrastructure operation tasks to AWS, allowing more focus on product value. In this question, however, separate Regions offer distinct geographic failure domains beyond one Region's AZs. The answer that meets the requirement is: Rehearse recovery and verify data replication rather than equating backups with instant failover.

D:

On-demand regional capacity makes phased geographical expansion practical. In this question, however, separate Regions offer distinct geographic failure domains beyond one Region's AZs. The answer that meets the requirement is: Rehearse recovery and verify data replication rather than equating backups with instant failover.
