Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 91

Question 900

An organization has a stable baseline of EC2 usage expected to continue for a year or longer. Which ongoing practice BEST sustains the intended result?

  1. Review minimum storage duration and retrieval fees before migration.
  2. Review contract type and tenancy requirements as separate decisions.
  3. Separate capacity assurance decisions from pricing-discount commitments.
  4. Review scope, family and term before making an RI commitment.

Explanation

Correct Answer

D:

Review scope, family and term before making an RI commitment. This continuing control fits because Reserved Instance pricing can provide a commitment-based discount for qualifying instance usage. The associated appropriate response is: Evaluate appropriate Reserved Instances for eligible steady workloads. An observable check is: A cost comparison shows a qualifying stable EC2 instance reservation matches its required instance attributes and term to receive the intended discount.

Incorrect Answers

A:

S3 tiers differ in storage pricing, access costs and retrieval characteristics. In this question, however, reserved Instance pricing can provide a commitment-based discount for qualifying instance usage. The answer that meets the requirement is: Review scope, family and term before making an RI commitment.

B:

A Savings Plan is a pricing agreement, not a guarantee of a specific physical server. In this question, however, reserved Instance pricing can provide a commitment-based discount for qualifying instance usage. The answer that meets the requirement is: Review scope, family and term before making an RI commitment.

C:

Capacity Reservations reserve supported instance capacity without being equivalent to an RI discount. In this question, however, reserved Instance pricing can provide a commitment-based discount for qualifying instance usage. The answer that meets the requirement is: Review scope, family and term before making an RI commitment.

Question 901

A company needs to choose between RDS and DynamoDB for an order system with many relational constraints. Which ongoing practice BEST sustains the intended result?

  1. Review domain data models and transaction requirements before selection.
  2. Reconcile data and monitor replication lag before cutover.
  3. Test converted code and data behavior separately.
  4. Plan data loading and cost controls for analytics separately.

Explanation

Correct Answer

A:

Review domain data models and transaction requirements before selection. This continuing control fits because Relational databases enforce structured relationships differently from NoSQL key-value models. The associated appropriate response is: Favor a relational service when SQL joins and transactional relationships are fundamental. An observable check is: A proof of concept supports the necessary multi-table relational queries and constraints.

Incorrect Answers

B:

DMS assists data movement and supported ongoing change capture between database endpoints. In this question, however, relational databases enforce structured relationships differently from NoSQL key-value models. The answer that meets the requirement is: Review domain data models and transaction requirements before selection.

C:

AWS SCT helps assess and convert database schema objects rather than merely copying table data. In this question, however, relational databases enforce structured relationships differently from NoSQL key-value models. The answer that meets the requirement is: Review domain data models and transaction requirements before selection.

D:

Analytical warehouses are designed for different query patterns than routine OLTP databases. In this question, however, relational databases enforce structured relationships differently from NoSQL key-value models. The answer that meets the requirement is: Review domain data models and transaction requirements before selection.

Question 902

A developer asks whether AWS service APIs are available only through the web console. Which precaution would MOST reduce the chance of the problem returning?

  1. Use role-based credentials and maintain SDK dependencies.
  2. Apply consistent IAM permissions regardless of access method.
  3. Document security and network boundaries between environments.
  4. Review dependencies and data boundaries before each migration phase.

Explanation

Correct Answer

B:

Apply consistent IAM permissions regardless of access method. This continuing control fits because Multiple access methods expose cloud capabilities for interactive and programmatic tasks. The associated appropriate response is: Recognize that supported AWS services can be accessed through console, CLI, SDKs and APIs. An observable check is: The same permitted resource details can be retrieved through approved console and CLI views.

Incorrect Answers

A:

SDKs provide supported service API integrations in application code. In this question, however, multiple access methods expose cloud capabilities for interactive and programmatic tasks. The answer that meets the requirement is: Apply consistent IAM permissions regardless of access method.

C:

Hybrid deployment combines on-premises resources with cloud services rather than requiring everything in one location. In this question, however, multiple access methods expose cloud capabilities for interactive and programmatic tasks. The answer that meets the requirement is: Apply consistent IAM permissions regardless of access method.

D:

Cloud and traditional infrastructures can coexist under a hybrid operating model. In this question, however, multiple access methods expose cloud capabilities for interactive and programmatic tasks. The answer that meets the requirement is: Apply consistent IAM permissions regardless of access method.

Question 903

An organization asks who is responsible for guarding AWS-owned regional data centers. Which ongoing practice BEST sustains the intended result?

  1. Include application dependency and secret hygiene in deployment reviews.
  2. Review database users and privileges during employee and role changes.
  3. Use AWS compliance documentation rather than inventing customer rack-control procedures.
  4. Audit KMS permissions and key lifecycle settings.

Explanation

Correct Answer

C:

Use AWS compliance documentation rather than inventing customer rack-control procedures. This continuing control fits because The provider operates physical cloud infrastructure that customers do not directly manage. The associated appropriate response is: Assign facility perimeter, building access and physical hardware security to AWS. An observable check is: The responsibility register lists physical facility controls as provider-operated.

Incorrect Answers

A:

Serverless execution management does not transfer customer application correctness or authorized access policy to AWS. In this question, however, the provider operates physical cloud infrastructure that customers do not directly manage. The answer that meets the requirement is: Use AWS compliance documentation rather than inventing customer rack-control procedures.

B:

Managed database operations do not replace customer data-level access decisions. In this question, however, the provider operates physical cloud infrastructure that customers do not directly manage. The answer that meets the requirement is: Use AWS compliance documentation rather than inventing customer rack-control procedures.

D:

Providing a managed key service does not remove the need for customer-defined access and rotation decisions. In this question, however, the provider operates physical cloud infrastructure that customers do not directly manage. The answer that meets the requirement is: Use AWS compliance documentation rather than inventing customer rack-control procedures.

Question 904

A deployment script needs nonsecret configuration parameters shared across environments. Which continuing control BEST supports this AWS approach?

  1. Review federated assignments and least-privilege policies together.
  2. Review role policies and prevent credential exfiltration.
  3. Disable shared identities and use a joiner-leaver process.
  4. Use secure parameter types for sensitive values and review IAM policies.

Explanation

Correct Answer

D:

Use secure parameter types for sensitive values and review IAM policies. This continuing control fits because Central configuration storage reduces environment-specific hardcoding and can manage access to parameters. The associated appropriate response is: Use AWS Systems Manager Parameter Store for controlled configuration values. An observable check is: A test environment retrieves only the intended configuration namespace.

Incorrect Answers

A:

Successful workforce sign-in is separate from permission to access particular AWS resources. In this question, however, central configuration storage reduces environment-specific hardcoding and can manage access to parameters. The answer that meets the requirement is: Use secure parameter types for sensitive values and review IAM policies.

B:

Role credentials avoid distributing static secrets with instance images or source code. In this question, however, central configuration storage reduces environment-specific hardcoding and can manage access to parameters. The answer that meets the requirement is: Use secure parameter types for sensitive values and review IAM policies.

C:

Shared credentials prevent reliable accountability and complicate revocation. In this question, however, central configuration storage reduces environment-specific hardcoding and can manage access to parameters. The answer that meets the requirement is: Use secure parameter types for sensitive values and review IAM policies.

Question 905

A company runs its own Linux web server on Amazon EC2 and asks who installs operating-system security patches. What follow-up practice BEST maintains the desired outcome?

  1. Maintain a customer patch schedule and inventory for self-managed instances.
  2. Validate new VPC routes against approved architecture policies.
  3. Enable access controls and periodic public-exposure reviews.
  4. Review permissions with each function release.

Explanation

Correct Answer

A:

Maintain a customer patch schedule and inventory for self-managed instances. This continuing control fits because AWS protects the underlying cloud infrastructure but customers administer EC2 guest operating systems. The associated appropriate response is: Assign guest operating-system patch management to the customer under shared responsibility. An observable check is: The owner documents and applies the approved Linux patch baseline to the EC2 guest.

Incorrect Answers

B:

AWS operates VPC infrastructure but does not decide the customer's intended permitted network topology. In this question, however, aWS protects the underlying cloud infrastructure but customers administer EC2 guest operating systems. The answer that meets the requirement is: Maintain a customer patch schedule and inventory for self-managed instances.

C:

The AWS-managed storage infrastructure does not automatically authorize the intended audience for each customer's objects. In this question, however, aWS protects the underlying cloud infrastructure but customers administer EC2 guest operating systems. The answer that meets the requirement is: Maintain a customer patch schedule and inventory for self-managed instances.

D:

AWS manages execution infrastructure while customers grant what their workloads can access. In this question, however, aWS protects the underlying cloud infrastructure but customers administer EC2 guest operating systems. The answer that meets the requirement is: Maintain a customer patch schedule and inventory for self-managed instances.

Question 906

An application needs a fast session store with predictable key access and no complex SQL transactions. Which continuing control BEST supports this AWS approach?

  1. Reconcile data and monitor replication lag before cutover.
  2. Validate access patterns before committing to a database model.
  3. Plan data loading and cost controls for analytics separately.
  4. Confirm required engine features, high-availability options and total cost before choosing Aurora.

Explanation

Correct Answer

B:

Validate access patterns before committing to a database model. This continuing control fits because Managed NoSQL models can match simple key-oriented workloads without relational table joins. The associated appropriate response is: Evaluate a NoSQL service such as DynamoDB instead of assuming all data needs an RDBMS. An observable check is: Session lookups return the expected values through a key-based design.

Incorrect Answers

A:

DMS assists data movement and supported ongoing change capture between database endpoints. In this question, however, managed NoSQL models can match simple key-oriented workloads without relational table joins. The answer that meets the requirement is: Validate access patterns before committing to a database model.

C:

Analytical warehouses are designed for different query patterns than routine OLTP databases. In this question, however, managed NoSQL models can match simple key-oriented workloads without relational table joins.

In this question, however, managed NoSQL models can match simple key-oriented workloads without relational table joins. The answer that meets the requirement is: Validate access patterns before committing to a database model.

Question 907

A business has regulatory equipment that must remain on site but needs to integrate with AWS cloud services. Which continuing control BEST supports this AWS approach?

  1. Use role-based credentials and maintain SDK dependencies.
  2. Apply consistent IAM permissions regardless of access method.
  3. Document security and network boundaries between environments.
  4. Use least-privilege console access and clean up test resources.

Explanation

Correct Answer

C:

Document security and network boundaries between environments. This continuing control fits because Hybrid deployment combines on-premises resources with cloud services rather than requiring everything in one location. The associated appropriate response is: Adopt a suitable hybrid-cloud deployment model. An observable check is: The operating plan identifies locally retained systems and approved cloud integration points.

Incorrect Answers

A:

SDKs provide supported service API integrations in application code. In this question, however, hybrid deployment combines on-premises resources with cloud services rather than requiring everything in one location. The answer that meets the requirement is: Document security and network boundaries between environments.

B:

Multiple access methods expose cloud capabilities for interactive and programmatic tasks. In this question, however, hybrid deployment combines on-premises resources with cloud services rather than requiring everything in one location. The answer that meets the requirement is: Document security and network boundaries between environments.

C:

Usage-based services provide cost signals that require suitable account and tagging organization. In this question, however, cloud cost benefits depend on sizing, demand, architecture, licenses and ongoing governance. The answer that meets the requirement is: Compare measured expenditure against the agreed business case.

D:

Duplicate infrastructure during migration can temporarily increase total spending. In this question, however, cloud cost benefits depend on sizing, demand, architecture, licenses and ongoing governance. The answer that meets the requirement is: Compare measured expenditure against the agreed business case.

Question 910

A team needs to migrate an actively changing relational database with limited downtime. Which precaution would MOST reduce the chance of the problem returning?

  1. Review data-export options and contractual exit obligations.
  2. Monitor replication lag and verify application compatibility separately.
  3. Plan post-migration optimization rather than assuming a lift-and-shift is final optimization.
  4. Test driver and engine differences before cutover.

Explanation

Correct Answer

B:

Monitor replication lag and verify application compatibility separately. This continuing control fits because DMS can capture supported source changes while initial data copies complete. The associated appropriate response is: Use AWS Database Migration Service for supported ongoing replication and cutover. An observable check is: The target is reconciled with a known source change point before cutover.

Incorrect Answers

A:

Repurchasing replaces an existing product with another offering, often a SaaS service. In this question, however, dMS can capture supported source changes while initial data copies complete. The answer that meets the requirement is: Monitor replication lag and verify application compatibility separately.

C:

Rehosting moves the workload with minimal application redesign or platform changes. In this question, however, dMS can capture supported source changes while initial data copies complete. The answer that meets the requirement is: Monitor replication lag and verify application compatibility separately.

D:

Replatforming changes selected infrastructure or platform components without fully reinventing the application. In this question, however, dMS can capture supported source changes while initial data copies complete.
