Point-to-Multipoint Mesh Network Site Survey Configurations

300-425 By islever Editorial Last updated

Short answer

BE Rx power and Tx power are the essential RF parameters configured and measured during a point-to-multipoint mesh site survey to validate link quality and coverage.

Question

An engineer is designing a point-to-multipoint mesh network. Which two AP configurations must be completed for a site survey? (Choose two.)
  1. MAP hostnames
  2. Rx power Correct Answer
  3. mesh on 2.4 GHz band
  4. bridge group name
  5. Tx power Correct Answer

Key Takeaways

Tests the distinction between network configuration (administrative) and site survey requirements (physical/RF). The common trap is selecting administrative identifiers like hostnames or bridge groups instead of radio parameters.

Identifies the critical physical layer parameters required for a successful point-to-multipoint mesh site survey. This page establishes that RF signal metrics, not administrative settings, are the mandatory configurations for surveying.

Common mistake: Candidates often choose A (MAP hostnames) and D (bridge group name), confusing standard AP setup tasks with the specific data collection needed for a wireless site survey.

Expert Analysis

Why the Answer Is Correct

The correct options are B (Rx power) and E (Tx power). A site survey is fundamentally an assessment of the Radio Frequency (RF) environment to ensure adequate coverage and capacity. To design a mesh network effectively, engineers must configure and measure Transmit (Tx) power to define the signal reach and Receive (Rx) power thresholds to ensure link quality. These two parameters directly impact the stability of the mesh backhaul links.

Why the Other Options Are Wrong

Options A (MAP hostnames) and D (bridge group name) are administrative configurations used for network management and identification. They do not influence the RF propagation characteristics or the physical layer performance measured during a site survey. While necessary for final deployment, they are irrelevant to the technical assessment of signal strength and interference.

Community Comment Notes

Community consensus strongly supports B and E. One user noted that the question focuses on 'design' rather than general 'configuring,' implying a need for technical parameters. Another user provided a reference to Cisco documentation supporting the configuration of these specific radio parameters for point-to-multipoint setups. Some dissenting votes chose A and D, likely misinterpreting the scope of the question as basic AP setup rather than RF engineering.

Exam Strategy

When a question asks about a 'site survey' or 'design phase', prioritize physical layer metrics (signal strength, channel width, interference) over logical/administrative settings (VLANs, names, passwords). Always distinguish between what is needed to build the network versus what is needed to validate its RF performance.

Frequently Asked Questions

Why are MAP hostnames not required for a site survey?

Hostnames are administrative identifiers for management. They do not affect RF signal propagation or link quality, which are the primary concerns of a site survey.

What is the difference between mesh configuration and site survey?

Configuration sets up logical attributes (like bridge groups). A site survey validates physical performance by measuring Tx and Rx power levels to ensure reliable connectivity.

    Selected answers are correct. His is not for configuring mesh but surveying
  2. NightmareCreature 👍 1
    Agreed with the others that the correct answer here B & E. Ref: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/point-to-multi-point/217959-configure-and-troubleshoot-a-point-to-mu.html

    B and E are the right answers. as we are talking about design not configuration
