Question 1

In a network, a node that connects two line segments is considered a(n):&#10;A) edge&#10;B) stop&#10;C) route&#10;D) junction

Accepted Answer

In a network, a node that connects two line segments is typically referred to as a junction. This term is used in various contexts, including transportation and communication networks, to describe a point where lines or paths intersect or branch.

Question 2

In a service area, the location for which you are determining the area of service is referred to as:&#10;A) Incident&#10;B) Source&#10;C) Feature&#10;D) Facility

Accepted Answer

In the context of service area analysis, the location for which you are determining the area of service is referred to as a "Facility." This term is used to denote the point or node from which services are provided, such as a hospital, fire station, or distribution center.

Question 3

&#34;Impedance&#34; refers to:&#10;A) The attribute assigned to a link in the GIS network's Turn Table&#10;B) The cost of traversing a network edge&#10;C) The cost associated with each network junction&#10;D) The cost time to establish dynamic segmentation in a GIS network

Accepted Answer

Impedance in the context of GIS (Geographic Information Systems) networks typically refers to the cost associated with traversing an edge or link in the network, such as the length of a road or the time it takes to travel a certain path.

Question 4

A Network Dataset is built from:&#10;A) Multiple shapefiles imported to a geodatabase&#10;B) A feature dataset consisting of multiple tables&#10;C) Feature classes within a feature dataset&#10;D) Feature classes in a geodatabase

Accepted Answer

Feature classes within a feature dataset are used to build a Network Dataset, as they allow for the integration of various types of networked data, such as roads, railways, and paths, within a single dataset for analysis and routing purposes.

Question 5

A process used to determine which locations on a network are nearest (via network distance) to a different set of locations is:&#10;A) Nearest Incident&#10;B) Network Buffer&#10;C) Closest Facility&#10;D) Service Area

Accepted Answer

The "Closest Facility" process in GIS (Geographic Information Systems) is used to find the nearest facilities to a given location or set of locations based on network distance, which can include roads, paths, or any other connectivity system. This process helps in determining the shortest or fastest paths from points of interest to facilities like hospitals, schools, or fire stations within a network.

Question 6

How is a service area different from a simple buffer?&#10;A) It can only be created around lines, unlike a regular buffer which can be created around all three vector objects.&#10;B) It is constrained by the edges of the network unlike a regular buffer.&#10;C) It can only be constructed in a designated urban setting, unlike a regular buffer that can be created anywhere.&#10;D) It cannot be created using a distance measurement, unlike a regular buffer.

Accepted Answer

A service area in geographic information systems (GIS) is specifically defined by the accessibility via a network, such as roads or paths, taking into account the actual travel distance or time. Unlike a simple buffer, which is a uniform area around a point, line, or polygon based on a set distance, a service area's shape and size are constrained by the network's structure, such as roads or paths, and how they can be traversed. This makes service areas particularly useful for planning and analysis in urban planning, logistics, and emergency response scenarios, where understanding accessible areas via the transportation network is crucial.

Question 7

The goal of Dijkstra's Algorithm is:&#10;A) To find all possible paths between an origin and another node in a network&#10;B) To find the shortest path between three or more stops by rearranging the travel order between the stops&#10;C) To find the overall shortest path between all stops on a network&#10;D) To find the shortest path between an origin and all other nodes in a network

Accepted Answer

Dijkstra's Algorithm is designed to find the shortest path from a starting node to all other nodes in a network, making it an efficient way to solve the shortest path problem in graph theory.

Question 8

The component of a network that describes how features properly link up with one another is:&#10;A) turns&#10;B) connectivity&#10;C) routing&#10;D) tracing

Accepted Answer

Connectivity in a network describes how features (like nodes, computers, devices) are linked or connected to one another, ensuring proper communication paths.

Question 9

What type of problem-solving technique is used when examining non-transportation routes?&#10;A) Flow&#10;B) Incident&#10;C) Trace&#10;D) Power

Accepted Answer

Trace is the correct problem-solving technique used when examining non-transportation routes, as it involves tracking or following a path or sequence, which is essential in non-transportation contexts to understand the flow or sequence of events or processes.

Question 10

The Traveling Salesman Problem is an example of:&#10;A) visiting stops in order&#10;B) rearranging the order of stops&#10;C) visiting stops in order but allowing the first and last stop to be rearranged&#10;D) rearranging all but the first and last stops of a network

Accepted Answer

The Traveling Salesman Problem involves finding the shortest possible route that visits each city exactly once and returns to the origin city, which inherently involves rearranging the order of stops to achieve the shortest path.
