Sample questions

Cloud Concepts

1. Which scenario best demonstrates the scalability benefit of the AWS Cloud?

• AA company keeps its server count fixed no matter how its traffic changes.
• BA company negotiates a lower price for its long-term hardware lease agreement.
• CA company stores backup copies of its data in a second geographic location.
• DA company adds servers automatically as traffic grows and removes them after.

Scalability is demonstrated by capacity growing and shrinking in response to actual traffic. A fixed server count is the opposite, lease negotiation is a procurement matter, and geographic backups demonstrate durability or disaster recovery rather than scalability.

Billing, Pricing, and Support

2. Which TWO actions would help a company reduce its monthly AWS bill? (Select TWO.)

• AStopping or terminating resources that are no longer being used at all.
• BRightsizing instances so their capacity matches actual workload needs.
• CProvisioning every environment at the largest available instance size.
• DLeaving all development environments running continuously overnight.
• EStoring all archival data in the most expensive storage class available.

Removing unused resources and rightsizing instances to actual need both directly reduce spend. Oversizing environments, leaving idle resources running, and using expensive storage classes for archives all increase cost.

Cloud Technology and Services

3. Which AWS service is designed to collect and process large streams of data records in real time?

• AAmazon S3 Glacier, which provides low-cost archival object storage.
• BAmazon Athena, which runs SQL queries against data stored in Amazon S3.
• CAWS Artifact, which provides on-demand access to compliance documents.
• DAmazon Kinesis, which collects and processes streaming data in real time.

Amazon Kinesis ingests and processes large streams of data in real time. Glacier is archival storage, Athena queries data at rest in S3, and Artifact provides compliance documentation.

Cloud Concepts

4. A company decides to redesign its application's architecture during migration so it can take advantage of cloud-native features such as serverless computing. Which migration strategy does this describe?

• ARehost, moving the application to AWS largely as-is with minimal changes.
• BRetain, keeping the application running in its current on-premises environment.
• CRelocate, moving virtual machines to AWS without changes to the application.
• DRefactor, redesigning the application to take advantage of cloud-native features.

Refactoring (or re-architecting) involves changing how an application is architected to take advantage of cloud-native features like serverless computing. Rehosting makes minimal changes, retaining keeps the application on premises, and relocating moves VMs without modification.

5. Which AWS service is used to create interactive dashboards and visualizations for business intelligence?

• AAmazon QuickSight, which creates interactive business intelligence dashboards.
• BAWS Glue, which discovers, catalogs, and transforms data for analytics.
• CAmazon Textract, which extracts text and data from scanned documents.
• DAmazon EFS, which provides a shared file system for multiple instances.

Amazon QuickSight is AWS's business intelligence service for building interactive dashboards and visualizations. Glue handles data preparation, Textract extracts document data, and EFS is shared file storage.

6. A team is reviewing a list of areas it believes are covered by the AWS Well-Architected Framework. Which item on the list is NOT one of the framework pillars?

• AReliability, covering a workload recovering from failures and meeting demand.
• BPerformance efficiency, covering efficient use of resources as demand changes.
• CVendor consolidation, covering reducing how many software suppliers are used.
• DOperational excellence, covering running and monitoring systems effectively.

Vendor consolidation is a procurement concern, not a Well-Architected pillar. Reliability, performance efficiency, and operational excellence are three of the six pillars, alongside security, cost optimization, and sustainability.
