Client/Server Essentials — What Is Not Required? Which of the following is NOT necessary to implement a client/server system?
-
AAssure that tools will connect with middleware.
-
BUnderstand the requirements.
-
CDetermine network bandwidth capabilities.
-
DInclude the use of a file server.
-
ESelect a protocol and security approach appropriate for the environment.
Answer
Correct Answer: Include the use of a file server.
Explanation
Introduction:Client/server is a flexible architectural pattern in which client applications consume services provided by servers over a network. Many elements contribute to a successful deployment, but not every environment needs a file server. This question identifies the item that is not strictly required.
Given Data / Assumptions:
- Client/server emphasizes service endpoints (for example, application and database servers).
- Middleware and tools must interoperate.
- Network capacity and security must be planned.
- A file server is optional, depending on use case.
Concept / Approach:Differentiate hard requirements from optional components. Middleware compatibility, requirement analysis, bandwidth planning, and protocol/security choices are baseline needs. A file server is only necessary if the solution explicitly requires shared file storage; many client/server systems operate without any file shares at all.
Step-by-Step Solution:1) Mark requirement analysis and bandwidth checks as universal planning tasks.2) Confirm middleware/tool compatibility is essential for connectivity and deployment.3) Recognize that file servers are not mandatory in architectures centered on APIs, application servers, and databases.4) Choose the file-server option as “not necessary.”
Verification / Alternative check:Modern web systems commonly use application and database servers without any SMB/NFS file shares; object storage or embedded storage may suffice.
Why Other Options Are Wrong:
- Middleware/tool interoperability: Required to ensure components can communicate.
- Understanding requirements: Fundamental to any system design.
- Bandwidth capability: Impacts performance and viability.
- Protocol/security selection: Core to interoperability and protection.
Common Pitfalls:Assuming every networked system needs shared file storage; many are purely service- and API-driven.
Final Answer:Include the use of a file server.
