What is the term for traffic between a website and a remote user's browser?

1. North-south

2. East-west

3. Unknown

4. Cloud

The correct answer is: North-south

Traffic between a website and a remote user's browser is referred to as "north-south" traffic. This term is used to describe the data flow that occurs between the data center or server and the end-user, typically over the internet. In networking terminology, north-south traffic pertains to the communication that moves vertically, either "up" to the cloud or data centers from end-users or "down" from these infrastructures to the users. This is crucial in understanding network architecture and how data is transmitted in and out of a system. The other terms, while relevant in different contexts, do not apply here. "East-west" traffic describes the data movement within the same data center, such as communication between servers or devices within a local network. "Cloud" is a broader term that encompasses services, storage, and computing resources that are provided over the internet, but it does not specifically denote the direction of traffic like "north-south" does. The option "unknown" simply indicates a lack of clarity, which does not pertain to the established terminology in cybersecurity and networking.
