Exam PK0-005 topic 1 question 137 discussion

D. Staging is a pre-production environment for testing but is not specific to tiered architectures. That’s why B makes the most sense.

This question is HOT GARBAGE. The question, as written, is flawed because it conflates the type of environment (e.g., development, testing, production) with the architecture of that environment (e.g., tiered, client-server, microservices). A tiered architecture can exist within any of those environment types. The question is asking about the architecture itself, not the environment it's deployed in. Tiered architecture fundamentally describes how network components are organized and interact. It's a network concept. While a tiered architecture impacts security, releases, and staging, it is a network architecture. The question forces a choice, and "network environment" is the most directly related to the concept of tiers. The best answer from the options provided (albeit still not ideal) is: B. Network environment.

o production. Tiered architecture in this context likely involves separating components of the application into different tiers or layers, such as presentation layer, business logic layer, and data layer

The requested tiered architecture setup typically aligns with a "Stage environment" (option D). In software development, a stage environment refers to an environment where software changes are tested before being promoted to production. Tiered architecture in this context likely involves separating components of the application into different tiers or layers, such as presentation layer, business logic layer, and data layer, each potentially residing on different servers or infrastructure.

D -Stage also means tiered

Choice "B" makes sense to me.

A "tiered architecture setup" typically refers to a "B. Network environment." In software engineering and network design, a tiered architecture often describes a client-server architecture in which the user interface, functional process logic, computer data storage, and data access are logically separated into different tiers or layers. This separation allows for more flexible maintenance and scalability.
