Final answer:
AWS Application Load Balancer (ALB) can distribute workload based on a packet's contents, as it operates at Layer 7 which allows content-based routing decisions.
Step-by-step explanation:
The AWS (Amazon Web Services) load balancing option that can distribute workload based on a packet's contents or payload is the AWS Application Load Balancer (ALB). The ALB operates at the application layer (Layer 7) of the OSI model, which allows it to inspect the contents of the HTTP/HTTPS traffic and make routing decisions based on content, such as URLs, headers, and cookies within the requests. On the other hand, the AWS Network Load Balancer (NLB) operates at the transport layer (Layer 4), utilizing IP protocol data for load balancing decisions but without the ability to inspect packet contents to the same extent as ALB.
