Question No 2:
What is a valid reason for opting for a 2-tier campus LAN design instead of a 3-tier design?
A. Cross-campus traffic has exceeded the capacity of a single collapsed core.
B. The campus has small buildings with limited wiring closets.
C. Access aggregation points are unable to scale to meet increasing traffic demands.
D. The network has expanded beyond a few building aggregation points.
Correct Answer: B. The campus has small buildings with limited wiring closets.
Explanation:
A 2-tier campus LAN design consists of two primary layers: the access layer (where end devices connect) and the distribution layer (which aggregates the traffic from the access layer). A 3-tier design adds an additional core layer, which acts as the backbone for interconnecting distribution layers across the campus.
The decision to choose a 2-tier design over a 3-tier design depends on factors such as the size of the campus, the number of buildings, and the level of traffic between buildings.
Option B (correct): A campus with small buildings and limited wiring closets typically does not need the complexity and overhead associated with a 3-tier design. The 2-tier design is sufficient for small-scale environments where there are fewer buildings, and the infrastructure requirements are simpler. This option provides a cost-effective and simpler approach to network design while meeting the needs of the campus.
Why the Other Options Are Not Correct:
Option A: If cross-campus traffic exceeds the capacity of a single collapsed core, this situation suggests that a more robust network infrastructure is required, typically provided by a 3-tier design. The core layer of a 3-tier design offers additional scalability and fault tolerance, making it better suited for handling high inter-building traffic.
Option C: If access aggregation points are unable to scale, this indicates that the network needs more capacity and redundancy, which is typically addressed by a 3-tier design. A core layer can help scale the network and balance traffic more effectively across the distribution layer.
Option D: If the network has expanded beyond a few building aggregation points, it may need the redundancy and scalability that a 3-tier design provides. A 3-tier design with a core layer would better handle the increased complexity of inter-building traffic.
In conclusion, a 2-tier design is more appropriate for small campuses with fewer buildings and simpler infrastructure requirements, where the complexity and cost of a 3-tier system are unnecessary. Therefore, B is the correct answer.
Question No 3:
In the absence of floor plans, what alternative source would be most effective for conducting site surveys or simulations when evaluating a space or building layout?
A. Fire Escape Plan
B. Blank Sheet of Paper
C. Simple Wall Drawings
D. Google Maps
Correct Answer: C. Simple Wall Drawings
Explanation:
When floor plans are unavailable, alternative sources can be used to gather spatial data for site surveys or simulations. Among the options provided, simple wall drawings are the most effective and practical source.
Why Simple Wall Drawings?
Simple wall drawings are useful because they provide a basic representation of the layout, showing walls, windows, and doors, which are essential for evaluating the space's dimensions and structure. While they may not have the technical accuracy of full floor plans, these sketches are still functional for simulations, basic planning, and spatial analysis. They can be created quickly and on-site, providing enough detail to proceed with further evaluations.
Other Options:
Fire Escape Plan: While fire escape plans are useful for safety purposes, they focus primarily on escape routes and emergency exits rather than detailed room layouts. They typically lack the information needed for simulations or in-depth spatial analysis.
Blank Sheet of Paper: Although it offers flexibility for sketching, a blank sheet of paper lacks any pre-existing information or structure. It requires significant effort to manually sketch the layout, which can be inefficient for simulations or site surveys.
Google Maps: Google Maps is excellent for large-scale outdoor navigation but doesn’t provide interior building layouts or details necessary for evaluating or simulating an indoor space. It offers an aerial view of the building's location but lacks the depth required for interior space analysis.
In summary, simple wall drawings provide sufficient information for site surveys and simulations when floor plans are unavailable, making them the best option.
