Question 1

An advantage of server-based architecture is that they never become overloaded and are always able to process user demands in a timely way.

Accepted Answer

Server-based architecture can become overloaded if there is insufficient processing power, bandwidth, or storage capacity. However, this can be mitigated with proper scaling and resource management strategies.

Question 2

Senior management has established the priority for the new system as "the highest security and control at any cost." The systems analyst should recommend a client-based computing architecture.

Accepted Answer

A client-based computing architecture may not provide the highest security and control as the majority of the processing and data storage occurs on the client devices rather than on centralized servers where security measures can be better controlled and maintained. A server-based or cloud-based architecture may be more appropriate for this priority.

Question 3

Most systems are not built to use the existing infrastructure in the organization, so the current infrastructure rarely restricts the choice of architecture.

Accepted Answer

Most systems are built based on the existing infrastructure in the organization, so the current infrastructure can limit the choice of architecture. The architecture needs to be compatible with the existing hardware, software, and network infrastructure to ensure seamless integration and efficient operation. Therefore, the existing infrastructure is an important consideration when designing a new system architecture.

Question 4

Server-based computing requires a high degree of coordination among many components, and the chances of security holes or control problems are much greater than with client-server computing.

Accepted Answer

Server-based computing simplifies management and can centralize security controls, potentially reducing the chances of security holes compared to distributed client-server environments where managing and securing multiple endpoints is more complex.

Question 5

A node in a deployment diagram typically indicates a server, a client or a separate network. A node never represents an individual network device since that is a very low level of abstraction for a deployment diagram.

Accepted Answer

A node in a deployment diagram can represent any physical resource in the system, including individual network devices. The level of abstraction depends on the detail needed for the model's purpose.

Question 6

Fundamentally, cloud computing is an umbrella technology that encompasses the ideas of ________________, service-oriented architectures, and grid computing.
A) Remote Method Invocation (RMI)
B) distributed computing
C) e-business
D) virtualization
E) networking

Accepted Answer

The answer of Fundamentally, cloud computing is an umbrella technology...

Question 7

In the server-based architecture, all data stored on one computer.

Accepted Answer

In a server-based architecture, all data is indeed stored on a central server, allowing clients connected to the network to access and manage the data from that single location.

Question 8

The hardware and software specification is a document that describes what hardware and software are needed to support the application.

Accepted Answer

The hardware and software specification document provides a comprehensive list of system requirements needed by the application. It outlines the minimum and recommended hardware and software configuration that will be able to accommodate the functions and features of the application.

Question 9

Companies seldom build networks to connect distant locations by buying land and laying cable or sending up their own satellites; they usually lease services provided by large telecommunications firms, such as AT&T, Sprint, and Verizon.

Accepted Answer

This statement is true. Many companies opt to lease services from telecommunications firms instead of building their own networks.

Question 10

The purpose of the network model is to convey the complexity of the system, to show how the system's components will fit together, and to help the project team develop the hardware and software specification.

Accepted Answer

The purpose of the network model is exactly as stated in the statement.

Question 11

Client-server architectures strive to balance the processing between the client and the server by having both perform some of the application functions.

Accepted Answer

This is generally true for client-server architectures, where the client handles some application functions on its own while delegating others to the server for processing. This helps to improve the overall performance and scalability of the system.

Question 12

The client-server architecture was originally developed to control and secure data, and it is much easier to administer because all data are stored in a single location.

Accepted Answer

The client-server architecture was originally developed to allow for distributed processing and to allow for sharing of resources. It does not necessarily control and secure data and may require more administration as data may be stored in multiple locations.

Question 13

A concurrent multilingual system is one that contains separate parts that are written in each language and must be reinstalled before a specific language can be used.

Accepted Answer

A concurrent multilingual system is one that allows for multiple languages to be used at the same time without needing to reinstall separate parts for each language.

Question 14

A two-tiered architecture uses only three sets of computers, clients, database servers, and application servers.

Accepted Answer

A two-tiered architecture typically involves two sets of computers: clients and servers, where the server can be a database server, but there is no separate application server layer involved.

Question 15

Project teams are usually more concerned with how an existing infrastructure needs to be changed or improved to support the requirements that were identified during analysis, as opposed to how to design and build an infrastructure from scratch.

Accepted Answer

Project teams typically focus on modifying existing infrastructure to meet the needs of the project rather than building a new infrastructure from the ground up.

Question 16

Senior management has established the priority for the new system as "user friendly, and quickly and inexpensively expandable to all part of the organization." The systems analyst should recommend a client-server based computing architecture.

Accepted Answer

A client-server architecture would allow for easy expansion to all parts of the organization, as well as providing a user-friendly interface for the system.

Question 17

In a deployment diagram, an artifact is a piece of the information system that is to be deployed onto the physical architecture.

Accepted Answer

This statement is true. An artifact represents any piece of software or code that needs to be deployed onto hardware resources in a deployment diagram.

Question 18

With the client-based architecture the clients are personal computers on a local area network and the server computer is a server on the same network.

Accepted Answer

In a client-based architecture, the clients are personal computers on a local area network and the server computer is a server on the same network.

Question 19

Which one in the following is one of the set of obstacles that cloud computing must overcome before it becomes the primary approach to provision the physical architecture layer.
A) the cost of the cloud
B) the level of availability of the cloud
C) the safety of the cloud
D) the security in the cloud
E) the usability of the cloud

Accepted Answer

The answer of Which one in the following is one...

Question 20

In a deployment diagram, typically a node is labeled with a stereotype, with the stereotype representing the type of node (e.g., web server, database server, mobile device).

Accepted Answer

This is true, nodes in a deployment diagram are typically labeled with a stereotype to represent the type of node they are (e.g. web server, database server, etc.).
