An administrator identifies some locations on the third floor of the building that have a poor wireless signal Multiple users confirm the incident and report it is not an isolated event. Which of the following should the administrator use to find the areas with a poor or non-existent wireless signal?
To identify areas with poor or non-existent wireless signals, an administrator should conduct a site survey. A site survey involves inspecting the location and measuring the wireless signal strength at various points within the building. This process helps in understanding the RF characteristics and the signal propagation, allowing the administrator to pinpoint areas with weak signal coverage. The data collected during a site survey can then be used to create a heat map for a visual representation of the signal strength across the area, but the initial step is to perform the site survey.
To find the areas with a poor or non-existent wireless signal, the administrator should conduct a wireless site survey. A wireless site survey is a process of planning and designing a wireless network by surveying the physical location to understand the RF (radio frequency) characteristics and signal propagation in the area. During a site survey, the administrator uses specialized tools and equipment to measure the wireless signal strength at various locations within the building. The data collected is then used to create a heat map, which visually represents the signal coverage and strength across the surveyed area. This heat map helps identify areas with poor or weak signal strength and allows the administrator to make informed decisions about the placement of wireless access points or other necessary adjustments to improve wireless coverage and performance.

Just answered yourself. You need a site survey to have a heat map
You DO a site survey, the question asks 'Which of the following should the administrator USE'?
Vague question - and, depending on where you look, it's either A or C. The thing is: was a site survey already done? If so, the heat map answer is correct, if not the site survey answer is correct. Who writes these questions?
These questions are stolen or memorized from real exams, it is likely that a question is not 100% the same as the actual question.
I work for a wireless modem tech company. When a user calls in to setup and test their modem we preform a site survey to evaluate the signal quality.
Site Survey. Need a Site survey in order to produce a heat map.
Isn’t the heat map the specific part of the site survey that identifies signal strength? The way I am interpreting the question is that it’s asking for a specific part of the site survey…heat map.
The question is 'Which of the following should the administrator USE', they should use a heat map. A site survey is an activity.
C. Site survey involves physically inspecting the area to measure the wireless signal strength and identify any interference or obstacles that may be causing the poor signal. By conducting a site survey, the administrator can create a detailed map of wireless coverage, pinpoint areas with weak signals, and determine the best placement for access points to improve coverage. While heat maps can be generated from the data collected during a site survey, they are not the primary tool used to identify areas with poor wireless signals. Heat maps provide a visual representation of signal strength across a given area, but they are typically generated after a site survey has been conducted.
Explanation: A site survey involves physically inspecting the premises to analyze wireless signal strength and coverage. During a site survey, the administrator can use specialized equipment to measure signal strength, identify dead zones or areas with poor coverage, and determine the optimal placement of access points for optimal coverage. Option A (Heat map) is related to visualizing wireless signal strength and coverage data, often generated from site surveys or other measurements, but it does not involve physically inspecting the premises to identify poor signal areas.
Chat GPT: A. Heat map: Heat maps can be generated based on data collected during a site survey to visually represent signal strength and coverage areas. However, generating a heat map requires conducting a site survey first to collect the necessary data. C. Site survey Conducting a site survey will provide the necessary information to accurately assess the wireless signal strength and coverage areas on the third floor of the building, enabling the administrator to address the issue effectively.
a heat map, to see where the dead zones are. there is not enough info to say site survey maybe if they said the building has thick concrete walls, between offices, I would go with a site survey but with the info given Heat Map to see where the dead zones are.
you use a site survey to MEASURE signal strength. Once you have your results you can create a heat map to show them using the red, green/blue colors
Adding COMPTIA's study guide notes: A site survey is used to measure signal strength and channel usage throughout the area to cover. A site survey starts with an architectural map of the site, with features that can cause background interference marked. These features include solid walls, reflective surfaces, motors, microwave ovens, and so on. The survey is performed with a Wi-Fi-enabled laptop or mobile device with Wi-Fi analyzer software installed. The Wi-Fi analyzer records information about the signal obtained at regularly spaced points as the survey or moves around the area. These readings are combined and analyzed to produce a heat map, showing where a signal is strong (red) or weak (green/blue), and which channel is being used and how they overlap.
Heat map for sure
It’s A
C* sorry
A heat map is a graphical representation of data that uses colors to indicate the density or intensity of certain values within a defined area. In this case, a heat map can visually represent the areas with a poor or non-existent wireless signal. By using a heat map, the administrator can quickly identify patterns, hotspots, or areas with signal issues. It provides a visual representation of signal strength across the third floor, allowing for easier identification of problem areas. Heat maps are commonly used to represent data in a way that is intuitive and easy to interpret, making them a suitable choice for this scenario
The #703 is similar to this question but the answer is Site Survey and that is something should be done first, here I think it should be Heat map
This is perhaps one of the worst question wordings with answers that are too similar. I think I am leaning towards site survey (C) only due to my inference based on the question's use of the word "find." If the admin is "finding" the areas of poor/nonexistent signal strength, to me, it implies those areas haven't yet been discovered. A heat map displays that signal information and the admin can certainly reference those same areas, however, as many have pointed out, a site survey would have to already have been conducted to produce a heat map. Plus, since the question took the time to describe how employees have confirmed it's an ongoing incident, it implies to me that nothing has been done yet to resolve the issue. Shaky, I know, however I am more comfortable with my inference based on the wording/context of the question rather than the inference that a site survey has randomly been conducted already and an existing heat map can be referenced.
