Question 1 of 52 from exam 300-425-ENWLSD: Designing Cisco Enterprise Wireless Networks


A network engineer is preparing for an office site survey with a height of 2.5 meters.

Which three components are recommended to complete the survey? (Choose three.)



A. B. C. D. E. F.


The correct answers are B, E, and F.

Explanation: A site survey is the process of analyzing and evaluating the wireless network's environment to ensure optimal performance, coverage, and connectivity. It involves various tasks such as measuring signal strength, interference levels, and noise, and determining the most suitable locations for the access points (APs).

Here are the explanations for the recommended components:

A. Use a battery pack to power APs: While a battery pack can be useful in some situations, it is not recommended for site surveys because it might not provide enough power to the APs, and the battery could run out of power during the survey, causing interruptions in the data collection.

B. Use a drawing of the office space to draw AP and client placements: A drawing of the office space is essential to plan the AP and client placements accurately. It allows the engineer to visualize the office's layout and identify potential obstacles that might affect the wireless signal, such as walls, furniture, and other wireless devices.

C. Use DoS attack on APs while measuring the throughput: A DoS attack is not recommended during a site survey because it is unethical and could disrupt the network's operations.

D. Use APs with directional antennas: Directional antennas are useful in specific scenarios where the wireless signal needs to be focused in a particular direction, such as outdoor bridges or point-to-point links. However, for a site survey in an office, where the wireless signal needs to cover a broad area, omni-directional antennas are the best choice.

E. Use APs with external antennas: External antennas provide flexibility in adjusting the AP's signal coverage and allow for the optimization of the wireless network's performance. They can be replaced or upgraded if needed, depending on the specific requirements of the wireless network.

F. Use APs with built-in antennas: APs with built-in antennas are easy to install and require minimal maintenance, but they are limited in their coverage and flexibility. They are suitable for small environments with simple wireless network requirements.

In summary, a site survey is a critical step in designing a reliable and efficient wireless network. The recommended components are a drawing of the office space, APs with external or built-in antennas, and avoiding unethical practices like DoS attacks.
