Local Area Network scope: Which kinds of devices are typically interconnected by a LAN within an organization?
-
AComputers and terminals
-
BMass storage device, printers and plotters
-
CBridges and gateways
-
DAll of the above
-
ENone of the above
Answer
Correct Answer: All of the above
Explanation
Introduction / Context:A Local Area Network (LAN) connects resources within a limited geographic area such as an office, building, or campus. Understanding what can be attached to a LAN clarifies the scope of shared services and traffic patterns in enterprise networks.
Given Data / Assumptions:
- The network spans a local environment.
- We consider both endpoints (users, peripherals) and interconnection devices.
- Modern Ethernet and switching are assumed, but the concept applies broadly.
Concept / Approach:
LANs link user devices (PCs, terminals), shared peripherals (printers, plotters, network-attached storage), and networking infrastructure (bridges, switches, routers, gateways). The objective is resource sharing, collaboration, and local service delivery with low latency and high throughput compared to wide-area links.
Step-by-Step Solution:
List device categories: user computers and terminals.Include shared peripherals: printers, plotters, mass storage (NAS/SAN gateways).Include interconnect devices: bridges and gateways for segmentation and connectivity.All categories belong on a LAN, so choose 'All of the above'.Verification / Alternative check:
Enterprise network diagrams show PCs, printers, storage arrays, and network devices connected at the access, distribution, and core layers within a LAN. This validates the inclusive nature of LAN attachment.
Why Other Options Are Wrong:
- Each single category is true but incomplete; the best comprehensive answer is 'All of the above'.
- None of the above: Incorrect because LANs commonly include all listed device types.
Common Pitfalls:
Overlooking infrastructure nodes as LAN members. Bridges, gateways, and switches are integral to segmentation, security, and routing between VLANs or to external networks.
Final Answer:
All of the above
