What are two functions of a server on a network? (Choose two)

A server's core purpose on a network is defined by its role in the client-server model. Its

primary functions are to run specialized software (applications/services) and to manage

and provide resources to multiple clients, often simultaneously. It listens for, processes,

and fulfills requests from these clients (workstations). This involves both running

applications that send and receive data and handling numerous requests concurrently

to ensure the network operates efficiently for all connected users.

•

A: Redundancy through clustering is a high-availability strategy and an advanced

feature, not a fundamental function of every server. Many servers operate as

standalone machines without clustering.

•

D: Servers use standardized network protocols (like TCP/IP, HTTP) to

communicate. Requiring the same operating system is false; networks are often

heterogeneous (e.g., Linux and Windows servers interacting).

•

E: This describes a specific hosting model (dedicated hosting or a private cloud).

A server's function is independent of its physical location or whether it serves a

single tenant or multiple tenants.

1. NIST Computer Security Resource Center (CSRC):

o Definition of a Server: The glossary defines a server as "A computer or

device on a network that manages network resources" and "A system

entity that provides a service in response to requests from clients." This

directly supports options B and C.

Control Systems Security."

2. Microsoft Learn Documentation:

o Description of Server Role: States that Windows Server is a platform for

"building an infrastructure of connected applications, networks, and web

services." It is designed for "enterprise-level management... data storage,

applications, and communications" and "supports many business use

cases, including web and application hosting." This confirms a server's

role in running applications for clients (Option B).

3. Cisco Networking Resources (via Third-Party Academic Explanation):

o Client-Server Model: Explains that the model "partitions tasks or

workloads between the providers of a resource or service, called servers,

and service requesters, called clients." This highlights that a server's job is

to run services and handle client requests (Option B). It also notes servers

"can manage tasks and services efficiently for multiple clients

simultaneously" (Option C).

4. Academic/Technical Explanation of Concurrency:

o Handling Concurrent Requests: Technical articles explain that a core

capability of a web server is to handle "multiple requests simultaneously

(concurrently) on a single port." This ability to manage concurrent

connections from many clients is a defining function of a server.
