Topology Mapping

Correct Answer: Refer to the hierarchical topology map

The most efficient and accurate method of determining which distribution switch a department's switch is connected to is by referring to the hierarchical topology map. This kind of map will usually illustrate how the network's switches, routers, and other devices are interconnected. Physically inspecting all distribution switches can be time-consuming, might not yield accurate results, and is impractical in a large network. Using a network monitoring tool could provide some insights but might not directly address the specific need which is the interconnection structure. Asking the user for a device hostname relies on the user's technical knowledge and is therefore not necessarily reliable.

Correct Answer: Physically inspect and document the new devices and connections

The best and first method of updating a topology map after expanding a network environment is to physically inspect and document the new devices and connections. This allows for the most accurate and up-to-date information on the new configuration and layout. Relying on network monitoring software might not detect all devices, especially newly installed devices, and may not understand how they are interconnected. Asking users where the devices are placed may lead to inaccurate information as users might not be aware of the correct network topology. Finally, relying on the existing map could result in outdated or incomplete network topology as the network has expanded. Therefore, physically inspecting and documenting the new devices and connections ensures that you capture all relevant and new information.

Correct Answer: Automated network mapping and documentation

The best solution to ensure an up-to-date topology map is maintained is by implementing an 'Automated network mapping and documentation'. Automated systems do not require human intervention and can continuously monitor network changes. They offer the benefit of immediate updates whenever changes occur, even if a technician is on vacation, ensuring consistency in network documentation. The other options are either less effective or not practical. Increasing the frequency of manual updates assumes a human is always available and can still miss real-time changes. Limiting network device additions can restrict business operations and expansion. Simplifying the network design might not be feasible according to business requirements and does not guarantee an up-to-date map.
