Question 6

Ethan is considering the replacement of the existing network for his organization. He has projected organizational growth at 50% per year for the next five years. With this growth, many new employees will surely be hired and trained. He has received a large amount of money from a small business grant for the initial development. The architecture Ethan should select is _____.
A) client-based
B) client-network server
C) client-server
D) network-based
E) server-based

Accepted Answer

With projected organizational growth at 50% per year for the next five years, selecting a client-server architecture is the best choice. This architecture allows for scalability and centralized management, which is essential for managing a growing organization. It also provides enhanced security and ensures reliable performance, making it a suitable choice for a business that is expected to expand rapidly. Additionally, the initial investment required for a client-server architecture is relatively low and would be covered by the small business grant Ethan received.

Question 7

What is one primary problem with server-based computing architectures?
A) As more users place heavier demands on the server, it is expensive to increase server capacity.
B) Client terminals are no longer made by hardware vendors.
C) It is difficult to maintain security in the server-based environment.
D) Servers are no longer made by hardware vendors.
E) Servers cannot be manufactured quickly by vendors.

Accepted Answer

The primary problem with server-based computing architectures is that as more users place heavier demands on the server, it is expensive to increase server capacity. This can lead to performance issues and slow down system operations.

Question 8

A server in the client-server architecture performs which of the following application functions?
A) application logic and data storage
B) application logic and presentation logic
C) data access logic and data storage
D) data access logic and presentation logic
E) data storage logic and presentation logic

Question 9

In an n-tiered architecture, the _____ is spread across two or more different sets of servers.
A) presentation logic
B) application logic
C) data access logic
D) data storage
E) any of the above can be spread across two or more sets of servers

Accepted Answer

The application logic is responsible for processing and manipulating data, and often requires significant computing power. As such, it is common for the application logic to be spread across multiple servers in an n-tiered architecture, in order to improve performance and scalability. The other options may also be split across servers, but it is most common for the application logic to be spread out.

Question 10

Scalability refers to the _____.
A) deployment of middleware in the system
B) ease of decreasing the cost of the infrastructure during economic downturn
