Exam AWS Certified Cloud Practitioner topic 1 question 72 discussion

Please can we get Moderator clarification here

The Answer is C & D. Reason being the questions says company is using AWS services that replicate "DATA" across multiple AZs. Both EC2 and EBS need to have manually triggered replication. Moreover, their purpose isn't DATA replication. Natively only C & D allow DATA replication in multiple AZs.

Amazon Aurora and Amazon DynamoDB

Answer is C and D. These questions need moderator attention.

Auto replication for C and D.

For a highly available architecture that replicates data across multiple Availability Zones on AWS, the services that support this requirement are: C. Amazon Aurora: Aurora is a relational database service that can replicate data across multiple Availability Zones for high availability and fault tolerance. D. Amazon DynamoDB: DynamoDB is a fully managed NoSQL database service that replicates data automatically across three Availability Zones in a single region to ensure high availability and durability. Both Aurora and DynamoDB provide options for replicating data across multiple Availability Zones, ensuring high availability for the retail company's ecommerce platform.

Answer: CD

https://aws.amazon.com/rds/aurora/features/#High_Availability_and_Durability https://aws.amazon.com/dynamodb/features/#Performance_at_scale C. Amazon Aurora: Amazon Aurora is a relational database service offered by AWS. It is designed to be highly available and durable, with automatic data replication across multiple Availability Zones. By using Amazon Aurora, the company can ensure that their database remains highly available even in the event of an Availability Zone failure. D. Amazon DynamoDB: Amazon DynamoDB is a fully managed NoSQL database service provided by AWS. DynamoDB is built for high availability and automatically replicates data across multiple Availability Zones within a region. It offers low-latency performance and can handle high traffic loads, making it suitable for building a highly available architecture for the e-commerce platform.

C and D have automatic replication capabilities.

It replicates data across multiple Availability Zones within a region, providing automatic failover and minimizing downtime in the event of an outage. D. Amazon DynamoDB: Amazon DynamoDB is a NoSQL database service that is designed for high availability and scalability. It automatically replicates data across multiple Availability Zones within a region, ensuring data durability and enabling continuous availability.

C. Amazon Aurora D. Amazon DynamoDB Amazon Aurora is a relational database service that automatically scales and replicates data across multiple Availability Zones for high availability and durability. Amazon DynamoDB is a NoSQL database service that provides consistent performance at any scale and automatically replicates data across multiple AWS regions and Availability Zones. While EC2, EBS, and Redshift can be configured to operate across multiple Availability Zones, they don't automatically replicate data across them, so Aurora and DynamoDB are the most suitable options for this requirement.
