Exam 11: Physical Architecture Layer Design

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 _____.

The major problem with a server-based architecture is that all data on the server must travel to the client for processing.

Scalability is an important attribute in today's systems. Client-server architectures tend to be more scalable compared to the server-based architectures.

The six architecture characteristics that assist in selecting the proper architecture are cost of infrastructure, cost of development, ease of development, _____, _____, and _____.

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.

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.

The function that provides the processing logic required by the human computer interaction layer is called presentation logic.

Define cultural and political requirements. Briefly describe four key areas of cultural and political requirements.

What are the issues related to security in the cloud?

In a deployment diagram, a communication path represents a communication link between the nodes of the physical architecture, and communication paths may be stereotyped.

Access control requirements state who can access data and what type of CRUD data access is permitted to each individual who has access to data.

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

Security concerns are one of the set of obstacles for adopting the cloud.

Minicomputer typically costs hundreds of thousands of dollars while a mainframe costs millions of dollars.

Capacity requirements, which are one kind of performance requirements, attempt to predict how fast the system should operate.

Assume an organization plans to launch a web-based order entry system that can be used directly by customers. Discuss four cultural and political requirements that need to be addressed when creating a system that will probably have users in multiple countries.

Scalability refers to the _____.

Define security requirements. Briefly describe four key areas of performance requirements.

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.

Scott and Tim need to implement a very secure system for the Johnson Space Flight Center. The Center has an endless hardware budget, so infrastructure costs are not a consideration. The Center has a well trained IS staff that is available for the project. Only six people will be interacting with the new system and they are engineers with years of computer experience. Scott and Tim do not see changes to the system in the near future. Using the six characteristics of a computing architecture, make an architecture selection recommendation to Scott and Tim.
