Amazon AWS Certified Cloud Practitioner CLF-C02 Practice Test 86
Question 850
A project manager compares AWS Global Accelerator with other AWS concepts while considering this need: an internet-facing app has regional endpoints and needs stable global entry points for traffic routing. Which pairing assigns the responsibilities or benefits correctly?
- AWS Global Accelerator: distribute components across isolated locations inside one geographic Region; Availability Zone: support global network traffic entry and endpoint routing
- AWS Global Accelerator: support global network traffic entry and endpoint routing; Multiple Availability Zones: place redundant application components across different AZs within a Region
- AWS Global Accelerator: place redundant application components across different AZs within a Region; Multiple Availability Zones: support global network traffic entry and endpoint routing
- AWS Global Accelerator: provide part of a multi-Region continuity plan; Multiple AWS Regions: support global network traffic entry and endpoint routing
Explanation
Correct Answer
B:The first pairing identifies AWS Global Accelerator with its actual role: use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints. The comparison is valid because Multiple Availability Zones instead addresses place redundant application components across different AZs within a Region.
Incorrect Answers
A:The roles are swapped. Availability Zone is associated with distribute components across Availability Zones for fault isolation; AWS Global Accelerator instead has the role: Use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints.
C:The roles are swapped. Multiple Availability Zones is associated with place redundant application components across different AZs within a Region; AWS Global Accelerator instead has the role: Use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints.
D:The roles are swapped. Multiple AWS Regions is associated with use a separate AWS Region as part of a multi-Region continuity plan; AWS Global Accelerator instead has the role: Use AWS Global Accelerator for global network traffic entry and endpoint routing. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints.
Question 851
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support global network traffic entry and endpoint routing?
- Data sovereignty Region choice
- Amazon CloudFront
- AWS Global Accelerator
- AWS Region
Explanation
Correct Answer
C:AWS Global Accelerator directly addresses this outcome. Global Accelerator provides static anycast IP addresses and routes traffic over the AWS global network to healthy endpoints. A common relevant example is: an internet-facing app has regional endpoints and needs stable global entry points for traffic routing.
Incorrect Answers
A:Data sovereignty Region choice instead focuses on a different requirement, such as a government customer requires that certain datasets be stored in a specified legal jurisdiction. Region choice is a customer decision for residency compliance, subject to service availability and contractual requirements. It is not the primary match for the requirement described here: support global network traffic entry and endpoint routing.
B:Amazon CloudFront global caching instead focuses on a different requirement, such as users worldwide download the same publicly available product images from an origin. CloudFront is AWS's content delivery network and can reduce latency by caching copies near viewers. It is not the primary match for the requirement described here: support global network traffic entry and endpoint routing.
D:AWS Region instead focuses on a different requirement, such as a company is selecting a separate geographic AWS location for a workload with residency requirements. A Region is a geographically separate area containing multiple Availability Zones; customers select deployment Regions. It is not the primary match for the requirement described here: support global network traffic entry and endpoint routing.
Question 852
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: apply layered identity, network and data-protection controls?
- AWS Security Hub
- Amazon GuardDuty
- AWS Organizations
- Defense in depth
Explanation
Correct Answer
D:Defense in depth directly addresses this outcome. Defense in depth reduces dependence on a single security mechanism by using multiple complementary safeguards. A common relevant example is: a security team wants more than a single network restriction protecting sensitive records.
Incorrect Answers
A:AWS Security Hub findings instead focuses on a different requirement, such as a security operations team wants a consolidated view of findings from multiple AWS security services. Security Hub centralizes security posture information and findings rather than storing application business data. It is not the primary match for the requirement described here: apply layered identity, network and data-protection controls.
B:Amazon GuardDuty threat detection instead focuses on a different requirement, such as 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. It is not the primary match for the requirement described here: apply layered identity, network and data-protection controls.
C:AWS Organizations governance instead focuses on a different requirement, such as a company needs centralized governance across many separate AWS accounts. Organizations groups accounts and supports policies and billing consolidation; it does not itself analyze threats. It is not the primary match for the requirement described here: apply layered identity, network and data-protection controls.
Question 853
Within the Security and Compliance domain, which business example MOST clearly illustrates AWS Marketplace, rather than a different AWS concept?
- A company wants to evaluate a third-party security product compatible with AWS workloads
- An analyst wants to investigate relationships among security findings after suspicious activity is detected
- A public application is concerned about distributed denial-of-service traffic
- An AWS user wants AWS-authored answers to common service troubleshooting and account questions
Explanation
Correct Answer
A:The decisive requirement is: Find third-party software offerings through AWS Marketplace. This is the role of AWS Marketplace. Marketplace lets customers discover and procure partner solutions; it is not the same as an AWS native security monitoring service.
Incorrect Answers
B:This describes a scenario for Amazon Detective investigations: use Amazon Detective to assist security investigations. Detective correlates supported signals for investigation; GuardDuty focuses on finding potential threats. It is not the most direct example of AWS Marketplace.
C:This describes a scenario for AWS Shield DDoS protection: use AWS Shield for DDoS protection capabilities. Shield provides managed DDoS protection rather than classifying sensitive objects or managing IAM identities. It is not the most direct example of AWS Marketplace.
D:This describes a scenario for AWS Knowledge Center: use AWS Knowledge Center articles for documented guidance. Knowledge Center provides guidance and answers; it is an information resource, not an active security enforcement tool. It is not the most direct example of AWS Marketplace.
Question 854
A learner is explaining EC2 instance store to colleagues facing this situation: a rendering workload needs high-performance temporary local scratch data that may be lost with its instance. Which explanation is MOST accurate?
- Deep Archive prioritizes low storage cost and accepts retrieval delays, unlike immediately accessed S3 classes.
- Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.
- Storage Gateway supports hybrid storage patterns and local caching for selected AWS-backed interfaces.
- S3 stores data as objects in buckets; it is not an attachable EC2 block device or shared POSIX file system.
Explanation
Correct Answer
B:Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume. The explanation directly connects EC2 instance store to use instance store for eligible ephemeral EC2 local storage for the stated requirement.
Incorrect Answers
A:This statement is true of S3 Glacier Deep Archive, which addresses a regulator requires long-term retention of records that will almost never be retrieved. It does not explain the particular role of EC2 instance store; Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.
C:This statement is true of AWS Storage Gateway, which addresses an on-premises application needs familiar file or storage interfaces connected to AWS cloud storage. It does not explain the particular role of EC2 instance store; Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.
D:This statement is true of Amazon S3 object storage, which addresses a business stores images and documents as objects accessed using service APIs. It does not explain the particular role of EC2 instance store; Instance store provides temporary local storage whose data does not have the durability properties of an EBS volume.
Question 855
A learner is explaining Amazon ECS to colleagues facing this situation: an application team needs AWS-native orchestration of container workloads. Which explanation is MOST accurate?
- Memory-optimized instances emphasize memory capacity relative to processing, fitting memory-intensive workloads.
- Storage-optimized instance families are designed for high local storage I/O and throughput needs.
- ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
- Elastic Load Balancing routes requests or connections to available targets rather than relying on one application instance.
Explanation
Correct Answer
C:ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options. The explanation directly connects Amazon ECS to use Amazon Elastic Container Service to manage containerized applications for the stated requirement.
Incorrect Answers
A:This statement is true of Memory-optimized EC2, which addresses a business runs an application that needs very large in-memory data structures. It does not explain the particular role of Amazon ECS; ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
B:This statement is true of Storage-optimized EC2, which addresses an analytics node needs high local disk throughput for temporary data processing. It does not explain the particular role of Amazon ECS; ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
D:This statement is true of Elastic Load Balancing, which addresses a website needs inbound requests distributed among several healthy application targets. It does not explain the particular role of Amazon ECS; ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options.
Question 856
A project manager compares AWS Secrets Manager with other AWS concepts while considering this need: an application needs controlled storage and rotation of a database password. Which pairing assigns the responsibilities or benefits correctly?
- AWS Secrets Manager: assume an appropriately trusted IAM role across accounts; Cross-account role access: meet this requirement: an application needs controlled storage and rotation of a database password
- AWS Secrets Manager: protect and rotate long-term programmatic API credentials; Access keys: meet this requirement: an application needs controlled storage and rotation of a database password
- AWS Secrets Manager: support application-user authentication and identity features; Amazon Cognito: meet this requirement: an application needs controlled storage and rotation of a database password
- AWS Secrets Manager: meet this requirement: an application needs controlled storage and rotation of a database password; Access keys: protect and rotate long-term programmatic API credentials
Explanation
Correct Answer
D:The first pairing identifies AWS Secrets Manager with its actual role: store and manage application secrets with AWS Secrets Manager. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret. The comparison is valid because Access keys instead addresses treat access keys as sensitive credentials and rotate or replace them where appropriate.
Incorrect Answers
A:The roles are swapped. Cross-account role access is associated with assume an appropriately trusted IAM role across accounts; AWS Secrets Manager instead has the role: Store and manage application secrets with AWS Secrets Manager. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret.
B:The roles are swapped. Access keys is associated with treat access keys as sensitive credentials and rotate or replace them where appropriate; AWS Secrets Manager instead has the role: Store and manage application secrets with AWS Secrets Manager. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret.
C:The roles are swapped. Amazon Cognito is associated with use Amazon Cognito for application-user authentication and identity features; AWS Secrets Manager instead has the role: Store and manage application secrets with AWS Secrets Manager. Secrets Manager manages sensitive credentials and supports rotation workflows; IAM policies determine who may retrieve a secret.

A software vendor needs full control of a virtual machine operating system for a legacy application. Which AWS service or cloud concept is the MOST direct match for this need?
- Amazon EC2
- Amazon ECS
- AWS Fargate
- Storage-optimized EC2
Explanation
Correct Answer
A:Amazon EC2 fits the need because eC2 offers virtual servers with selectable instance types and customer-managed guest operating systems. The relevant capability or responsibility is: Use Amazon EC2 for configurable virtual compute instances.
Incorrect Answers
B:Amazon ECS is associated with a different use case: an application team needs AWS-native orchestration of container workloads. ECS manages deployment and scheduling of containers, with eligible EC2 or Fargate capacity options. The question instead focuses on a software vendor needs full control of a virtual machine operating system for a legacy application; Amazon EC2 is the more direct match.
C:AWS Fargate is associated with a different use case: a development team wants to run supported containers without managing the underlying EC2 host fleet. Fargate supplies compute capacity for supported container tasks without customers administering container hosts. The question instead focuses on a software vendor needs full control of a virtual machine operating system for a legacy application; Amazon EC2 is the more direct match.
D:Storage-optimized EC2 is associated with a different use case: an analytics node needs high local disk throughput for temporary data processing. Storage-optimized instance families are designed for high local storage I/O and throughput needs. The question instead focuses on a software vendor needs full control of a virtual machine operating system for a legacy application; Amazon EC2 is the more direct match.

- Amazon SageMaker AI
- Amazon Kinesis
- Amazon Lex
- Amazon Rekognition
Explanation
Correct Answer
B:Amazon Kinesis directly addresses this outcome. Kinesis includes streaming data capabilities suitable for near-real-time events. A common relevant example is: an application wants to capture and process a continuous stream of event records.
Incorrect Answers
A:Amazon SageMaker AI instead focuses on a different requirement, such as a machine learning team needs tools to build and deploy custom ML models. SageMaker AI supports building, training and deploying ML models rather than simply translating text. It is not the primary match for the requirement described here: support real-time streaming data ingestion and processing use cases.
C:Amazon Lex instead focuses on a different requirement, such as a company wants a conversational bot that interprets user requests in a customer service channel. Lex provides conversational AI for chatbots and voice-enabled applications. It is not the primary match for the requirement described here: support real-time streaming data ingestion and processing use cases.
D:Amazon Rekognition instead focuses on a different requirement, such as a media team wants managed analysis of image or video content without developing its own vision model. Rekognition applies pretrained computer vision to supported image and video analysis tasks. It is not the primary match for the requirement described here: support real-time streaming data ingestion and processing use cases.
Question 859

- S3 Glacier Deep Archive
- AWS Backup
- S3 Standard-IA
- Amazon EBS
Explanation
Correct Answer
D:Amazon EBS fits the need because eBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration. The relevant capability or responsibility is: Use Amazon EBS volumes for persistent EC2 block storage.
Incorrect Answers
A:S3 Glacier Deep Archive is associated with a different use case: a regulator requires long-term retention of records that will almost never be retrieved. Deep Archive prioritizes low storage cost and accepts retrieval delays, unlike immediately accessed S3 classes. The question instead focuses on a database server on EC2 needs persistent block storage beyond the life of one specific host; Amazon EBS is the more direct match.
B:AWS Backup is associated with a different use case: 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. The question instead focuses on a database server on EC2 needs persistent block storage beyond the life of one specific host; Amazon EBS is the more direct match.
C:S3 Standard-Infrequent Access is associated with a different use case: a business rarely accesses certain long-lived backup files but needs them rapidly when requested. S3 Standard-IA has lower storage charges but access and minimum-duration considerations compared with frequently accessed classes. The question instead focuses on a database server on EC2 needs persistent block storage beyond the life of one specific host; Amazon EBS is the more direct match.
