Difficulty: Easy
Correct Answer: Applies — that is a correct description of client/server LANs
Explanation:
Introduction / Context:
Client/server environments rely on networks to connect user devices (clients) to shared resources hosted on servers. A LAN provides the communication fabric so clients can access printers, file servers, databases, application servers, and web services while still retaining local storage and processing.
Given Data / Assumptions:
Concept / Approach:
Client/server separates concerns: user interface and some logic execute on clients; centralized services and data reside on servers. LAN connectivity (Ethernet/Wi-Fi) enables resource sharing, authentication, and centralized administration alongside local capabilities on each PC.
Step-by-Step Solution:
Clients join the LAN with IP configuration.Servers advertise resources via network protocols.Clients access shared devices or software while still saving files locally if permitted.Directory services apply policies and permissions across the LAN.Applications may use database connections over the LAN to a DB server.
Verification / Alternative check:
Observe common office networks: users print to shared printers and access shared drives while also using local drives, matching the description.
Why Other Options Are Wrong:
Option b denies basic LAN sharing capabilities. Option c is needlessly restrictive; wired/wireless both qualify. Option d contradicts “client/server.” Option e confuses LANs with thin-client or diskless environments, which are optional.
Common Pitfalls:
Assuming all processing must be server-side; ignoring security and access control; overlooking bandwidth and QoS needs for database-heavy applications.
Final Answer:
Applies — that is a correct description of client/server LANs
