Question 1

A company purchased Amazon EC2 Standard Reserved Instances (Rls) for a workload in the AWS Cloud. The company needs to move part of the workload to an instance family that does not match the instance family of these Standard RIs.

How can the company take advantage of the Standard RIs that it no longer needs?



Answer : B

The Amazon EC2 Reserved Instance Marketplace allows customers to sell unused Standard Reserved Instances to other AWS users. This enables companies to recoup some of the costs if they no longer need certain RIs. Standard RIs cannot be converted to Savings Plans, and AWS Support does not facilitate the resale of RIs directly.


Question 2

A company wants to visualize and manage AWS Cloud costs and usage for a specific period of time.

Which AWS service or feature will meet these requirements?



Answer : A

Cost Explorer enables visualization and analysis of AWS costs and usage over specific time periods. It provides detailed reports, trends, and forecasts for cost management. Consolidated billing and AWS Organizations are useful for billing management across accounts, while AWS Budgets helps set spending thresholds but does not provide visualization tools for cost and usage.


Question 3

Which AWS service provides machine learning capability to detect and analyze content in images and videos?



Answer : D

Amazon Rekognition provides machine learning capabilities to analyze images and videos, enabling the detection of objects, people, text, and scenes. It is designed specifically for image and video analysis, making it suitable for various use cases like facial recognition and content moderation. Other services like Amazon Connect, Lightsail, and Personalize do not offer image or video analysis capabilities.


Question 4

A user wants to invoke an AWS Lambda function when an Amazon EC2 instance enters the "stopping" state.

Which AWS service is appropriate for this use case?



Answer : A

Amazon EventBridge (formerly CloudWatch Events) allows users to respond to changes in the state of AWS resources. It can be configured to invoke an AWS Lambda function when an EC2 instance enters the ''stopping'' state, providing a serverless way to automate responses to changes in EC2 instance states. AWS Config, SNS, and CloudFormation do not provide direct triggering for specific instance state changes.


Question 5

A company needs to block SOL injection attacks.

Which AWS service or feature provides this functionality?



Answer : A

AWS WAF is a web application firewall that helps protect applications from SQL injection attacks and other common web exploits. By defining rules to block, allow, or monitor specific types of requests, AWS WAF provides an effective defense against SQL injection. Network ACLs and Security Groups provide network-level security but do not inspect web traffic for specific attack patterns like SQL injection.


Question 6

A company wants to run a graph query that provides credit card users' names, addresses, and transactions. The company wants the graph to show if the names, addresses, and transactions indicates possible fraud.

Which AWS database service will meet these requirements?



Answer : D

Amazon Neptune is a managed graph database service that is well-suited for complex queries involving relationships, such as detecting patterns indicative of fraud in credit card transactions. It supports graph query languages like Gremlin and SPARQL, making it ideal for use cases requiring intricate relationship analysis. DocumentDB, Timestream, and DynamoDB are not designed for graph-based queries.


Question 7

A cloud engineer wants to store data in Amazon S3. The engineer will access some of the data yearly and some of the data dally.

Which S3 storage class will meet these requirements MOST cost-effectively?



Answer : D

S3 Intelligent-Tiering is cost-effective for data with unpredictable access patterns. It automatically moves data between two access tiers (frequent and infrequent) based on access patterns, which is suitable for data accessed daily or infrequently. S3 Glacier Deep Archive is for archival data accessed infrequently, and S3 One Zone-IA is for infrequent access data stored in a single availability zone, which may not be ideal for data accessed daily.
