A company wants to run its application on Amazon EC2 instances. The company needs to keep the application on-premises to meet a compliance requirement.
Which AWS offering will meet these requirements?
A. Dedicated Instances
B. Amazon CloudFront
C. AWS Fargate
D. AWS Outposts
Show Answer
Correct Answer: D
Explanation: AWS Outposts extends AWS infrastructure, services, APIs, and tools to an on-premises data center, allowing Amazon EC2 instances to run on-premises while meeting compliance requirements. Dedicated Instances still run in AWS Regions, CloudFront is a CDN, and AWS Fargate is a serverless compute engine for containers, not an on-premises offering.
Question 83
A company needs to block SQL injection attacks.
Which AWS service or feature provides this functionality?
A. AWS WAF
B. Network ACLs
C. Security groups
D. AWS Trusted Advisor
Show Answer
Correct Answer: A
Explanation: AWS WAF (Web Application Firewall) includes managed and custom rules that can detect and block common web exploits such as SQL injection attacks. Network ACLs and security groups filter network traffic but do not inspect HTTP requests for SQL injection, and AWS Trusted Advisor provides recommendations rather than real-time attack protection.
Question 84
A company needs to provision uninterruptible Amazon EC2 instances, when needed, and pay for compute capacity by the second.
Which EC2 instance purchasing option will meet these requirements?
A. Reserved Instances
B. Spot Instances
C. On-Demand Instances
D. Dedicated Instances
Show Answer
Correct Answer: C
Explanation: On-Demand Instances are provisioned when needed, are not interruptible by AWS, and are billed per second for supported operating systems after a 60-second minimum. Spot Instances can be interrupted, Reserved Instances are a billing discount rather than an on-demand purchasing model, and Dedicated Instances provide single-tenant hardware but do not specifically address the pay-as-needed requirement.
Question 85
A company wants to consolidate its call centers to improve the customer voice and chat experience with call center agents.
Which AWS service or tool will meet these requirements?
A. Amazon Simple Notification Service (Amazon SNS)
B. AWS Support Center
C. Amazon Cognito
D. Amazon Connect
Show Answer
Correct Answer: D
Explanation: Amazon Connect is AWS's cloud-based contact center service designed to consolidate customer service operations and provide voice and chat experiences for customers and agents. Amazon SNS is for messaging/notifications, AWS Support Center is for AWS support cases, and Amazon Cognito is for user identity and authentication.
Question 86

Which perspective of the AWS CAF addresses the strategy management capability?
A. Business perspective
B. People perspective
C. Governance perspective
D. Operations perspective
Show Answer
Correct Answer: A
Explanation: The AWS Cloud Adoption Framework (AWS CAF) Business perspective includes the strategy management capability. It focuses on aligning cloud adoption with business objectives, ensuring cloud investments deliver business value and support strategic outcomes. The Governance perspective focuses on decision-making, risk, compliance, financial oversight, and policy enforcement rather than strategy management.
Question 87
A company has deployed several public applications behind Application Load Balancers. The company wants to improve the performance of the applications.
Which AWS service will meet these requirements?
A. AWS Global Accelerator
B. Amazon Connect
C. Amazon ElastiCache
D. Amazon CloudWatch
Show Answer
Correct Answer: A
Explanation: AWS Global Accelerator improves the performance and availability of internet-facing applications by routing user traffic over the AWS global network to the optimal regional endpoint, including Application Load Balancers. Amazon Connect is a contact center service, ElastiCache improves database/application caching rather than ALB network routing, and CloudWatch is for monitoring.
Question 88
A company plans to launch an ecommerce website that contains many images for a product catalog. The company wants to keep the cost of running the website within a specific budget.
Which AWS service or tool should the company use to monitor the ongoing costs of the website?
A. AWS Cost Explorer
B. AWS SDKs
C. EC2 Image Builder
D. AWS CloudFormation
Show Answer
Correct Answer: A
Explanation: AWS Cost Explorer is the AWS service designed to monitor, analyze, and forecast AWS spending over time. It helps track ongoing costs and usage, making it the best choice for keeping website costs within a budget. AWS SDKs are development libraries, EC2 Image Builder creates and manages machine images, and AWS CloudFormation provisions infrastructure rather than monitoring costs.
Question 89
A company wants to test a new application.
Which AWS principle will help the company test the application?
A. Make long-term commitments in exchange for a cost discount.
B. Scale up and down when needed without any long-term commitments.

D. Manage all of the maintenance tasks associated with the cloud.

This makes it ideal for testing new applications while minimizing cost and avoiding upfront infrastructure investments.

Show Answer
