N-Tier Architecture

N-tier architectures usually have at least how many separate logical parts?

The nth tier needs to know how to handle requests from which tier(s)?

Communication between tiers is typically ___ to support better scalability.

Which correctly distinguishes layers from tiers?

A CAD tool must run heavy computation locally on office PCs whose capabilities are known in advance. Which model best fits?

A major disadvantage of the fat-client model is:

Which is NOT one of the four main benefits of the N-tier style?

N-tier communication and distribution is usually handled by:

Which of these is a genuine challenge of N-tier architectures?

The thin-client model is especially used when:

Multiple logical layers may reside on the same physical tier.

In N-tier architecture, each tier is completely independent from all other tiers except those immediately above and below it.

Tiers are the physical deployment of layers.

In the fat-client model, all data management is performed on the client.

N-tier improves scalability, availability, manageability, and resource utilization.

The thin-client model places a light load on the server and network.

In a two-tier architecture, the system is implemented as a single logical server plus many clients.

Designing truly reusable objects in N-tier systems is easy and always satisfies future needs.

In N-tier, the layers include Presentation, Data Management, Application Processing, and Database.

General distributed object protocols are typically very fast.

Match each layer with its responsibility.

Match each term with its meaning.

Match each client model with its characteristic.

Match each N-tier benefit with its meaning.

Match each middleware technology / concept with its category.
