Question 1

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

Client-server architecture allows for easy and cost-effective expansion to different parts of the organization. It also allows for a more user-friendly interface for the end-users.

Question 2

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 3

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

Client-server architectures distribute application functions between the client and server to achieve a balance between processing power and workload.

Question 4

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 developed to allow multiple clients to access and share data from a central server. While it does offer some control and security benefits, it does not necessarily make data easier to administer because the data may need to be managed and accessed by multiple clients.

Question 5

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. Rather than building their own networks, most companies lease services from large telecommunications firms.

Question 6

The ______________is the idea that, in addition to things having some form of computing capacity built into them, everyday things become connected via the Internet.
A) cloud computing
B) big data
C) machine learning
D) Internet of Things (IoT)
E) e-business

Accepted Answer

True False

Question 7

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 work on improving or modifying existing infrastructures rather than starting from scratch.

Question 8

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 can switch between multiple languages without requiring separate installations for each language. Each language module is integrated into the system and can be activated or deactivated as needed.

Question 9

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 security in the cloud
D) the safety of the cloud
E) the usability of the cloud

Accepted Answer

Security is one of the main obstacles that cloud computing has to overcome before becoming the primary approach to provision the physical architecture layer. Cloud security concerns include unauthorized access, data breaches, privacy issues, and lack of control over the infrastructure. These concerns must be addressed before cloud computing can become widely adopted. While the cost, availability, usability, and safety of the cloud are important factors, security is a critical consideration that can determine the success or failure of cloud implementations.

Question 10

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

With the client-based architecture, the clients are usually personal computers or mobile devices that are connected to a server through a local area network, and the server computer is located on the same network as the clients.

Question 11

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 12

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 13

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 14

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

Accepted Answer

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

Question 15

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 and unable to handle user demands if there is a sudden increase in traffic, hardware failure, or software issues.

Question 16

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

Accepted Answer

The statement is true as the hardware and software specification document outlines the required hardware and software components necessary to support the application.

Question 17

Essentially, ___________computing is the idea that computing takes place everywhere and in everything.
A) Internet
B) cloud
C) ubiquitous
D) data
E) business

Accepted Answer

The term "ubiquitous computing" refers to the concept of computing being present and operational everywhere and anywhere, without the need for explicit user intervention. This is supported by a network of interconnected devices and objects that communicate and exchange data seamlessly. The other options, such as internet, cloud, data, or business, do not fully capture this idea of computing being omnipresent.

Question 18

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 statement is true. Nodes in a deployment diagram are often labeled with a stereotype that represents the type of node they represent, such as a web server or database server. This helps to clarify the roles of different nodes in a deployment environment.

Question 19

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 would not be the most suitable option for achieving the highest security and control since it typically involves more decentralized control and management of devices, which could increase security risks. Instead, a centralized, server-based architecture with strong access controls and monitoring would likely be recommended to meet this priority.

Question 20

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 network model is a visual representation of how the system's components will interact and communicate with each other. It helps to identify potential design problems, anticipate communication issues, and ultimately develop a hardware and software specification that meets the project requirements. Therefore, the purpose of the network model is to convey the complexity of the system and to help the project team develop the necessary hardware and software.
