AWS Global Accelerator and Amazon CloudFront are separate services that use the AWS global network and its edge locations around the world.
AWS Global Accelerator allows you to route requests for key resources through Amazon’s global network—even if the request is going halfway round the world. The request is initially routed to the closest edge location and then travels through Amazon’s network—often with lower latency and higher throughput than the public internet.
AWS Global Accelerator helps bridge the gap between single and multiple Region deployments by improving the network routing for local and global user traffic. If traffic to your application’s single Region is left on the public internet, it can be negatively impacted by internet congestion and local outages. Using Global Accelerator, your users' traffic is moved off the internet and onto Amazon’s private global network through 90+ global edge locations, then directed to your application origins. AWS Global Accelerator is quick to setup and increases traffic performance by up to 60%.
A company needs to install an application in a Docker container.
Which AWS service eliminates the need to provision and manage the container hosts?

AWS Snow Family - The AWS Snow Family is a collection of physical devices that help migrate large amounts of data into and out of the cloud without depending on networks. This helps you apply the wide variety of AWS services for analytics, file systems, and archives to your data. You can use AWS Snow Family services for data transfer and occasional pre-processing on location. Some large data transfer examples include cloud migration, disaster recovery, data center relocation, and/or remote data collection projects. These projects typically require you to migrate large amounts of data in the shortest, and most cost-effective, amount of time.
A retail company needs to build a highly available architecture for a new ecommerce platform. The company is using only AWS services that replicate data across multiple Availability Zones.

Amazon EC2
Amazon Elastic Block Store (Amazon EBS)
Amazon Aurora
Amazon DynamoDB
Amazon Redshift
Answers are;
C. Amazon Aurora
D. Amazon DynamoDB
The question 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.
