Question: 1
A wireless engineer must design a backhaul link. The engineer has a mesh access
point that has a
wired connection back to the infrastructure. What must be changed in the AP role
before a change is made in the AP mode?
A. monitor
B. RAP
C. bridge
D. local
Answer: B
Explanation:
In Cisco mesh networking architecture, access points are classified into two
primary roles: Root
Access Points (RAP) and Mesh Access Points (MAP). A RAP is an access point that
maintains a wired
Ethernet backhaul connection back to the network infrastructure, while a MAP
operates wirelessly,
relying on mesh backlinks to upstream RAPs. When an engineer needs to change an
AP mode — such
as switching to bridge mode to extend the mesh — the AP role must first be
defined correctly. The AP
must be designated as a RAP before any mode-level configuration changes are
applied. This
sequencing is critical because the AP role defines the fundamental backhaul
path; changing the
Questions and Answers PDF 2/100
mode without first establishing the role results in misconfiguration and
potential connectivity loss.
The RAP communicates directly with the wired infrastructure via its Ethernet
port, making it the
gateway for all downstream MAPs in the mesh topology. Options A (monitor), C
(bridge), and D
(local) refer to AP modes, not roles, and cannot be configured until the role is
properly defined.
Reference: WLSD Study Guide — Mesh Networking Fundamentals, Outdoor Wireless
Design, AP Role
and Mode Configuration.
Question: 2
A customer is planning to replace older access points with Cisco 4800 Series
Access Points.
Unaware of the infrastructure requirements, the client has an engineer
investigate the inline power
requirement. Which IEEE 802.3 standard complies with the Cisco 4800 Series
Access Points?
A. 802.3bt
B. 802.3af
C. 802.3ac
D. 802.3at
Answer: A
Explanation:
The Cisco Aironet 4800 Series Access Point is a tri-radio, high-performance
access point designed for
high-density environments. It draws significantly more power than older
dual-radio APs and requires
IEEE 802.3bt (also known as PoE++), which provides up to 90W per port at the
Power Sourcing
Equipment. IEEE 802.3af (Type 1 PoE) delivers only 15.4W and 802.3at (Type 2 PoE+)
provides up to
30W — both are insufficient for full functionality of the 4800 series. The
dedicated third security
radio on the 4800 pushes the power budget beyond what 802.3at can reliably
support. IEEE 802.3ac
is a VLAN tagging standard entirely unrelated to Power over Ethernet. Engineers
designing wired
infrastructure for Cisco 4800 deployments must ensure switches support 802.3bt
Type 3 or Type 4 to
guarantee full AP functionality across all three radios simultaneously.
Reference: WLSD Study Guide
— Wired Infrastructure Design, PoE Standards and Power Budget Planning, Cisco
4800 Series AP Specifications.
Question: 3
During a site survey for a new wireless deployment in a multifloor office
building, an engineer must
identify sources of interference and ensure optimal AP placement for 5 GHz
coverage.
While walking the site with a spectrum analyzer, the engineer notices periodic
spikes in the noise floor on several
channels and inconsistent signal strengths reported by the survey tool, despite
visually unobstructed paths.
Which action must the engineer take next to accurately assess and mitigate the
Layer 1 interference?
A. Increase the transmit power of all APs to compensate for the signal
fluctuations and re-run the
survey to verify the visual line-of-sight and signal strength measurements.
B. Use the wireless controller monitoring tools in combination with the site
survey tool heatmap
output to determine AP locations and capture the Layer 1 spectrum analysis for
ongoing analysis.
C. Document the affected channels and locations, then attempt to adjust the
channel plan to avoid
the frequencies that experience the most interference during initial deployment.
D. Use the spectrum analyzer to document the time, frequency, and location of
the noise spikes,
then correlate them with possible non-Wi-Fi interferers and adjust AP placement
accordingly.
Answer: D
Explanation:
Layer 1 interference analysis is foundational to the Cisco site survey
methodology. When a spectrum
analyzer reveals periodic noise floor spikes across multiple channels with no
clear line-of-sight
obstruction, the root cause is almost certainly a non-802.11 device — candidates
include cordless
phones, video cameras, microwave equipment, or radar systems triggering DFS
events. The correct
engineering response is systematic documentation: capture the time of
occurrence, the specific
frequency or frequency range, and the geographic location of the interference
signature. This
triangulation data enables correlation with physical devices present in the
facility. Simply increasing
transmit power (Option A) raises the noise floor for neighboring cells and
worsens co-channel
interference. Using WLC monitoring tools (Option B) is insufficient because the
WLC cannot detect
non-802.11 energy at Layer 1. Adjusting the channel plan (Option C) without
fully characterizing the
interferer is premature. Only Option D follows the correct Cisco survey
methodology for Layer 1
Questions and Answers PDF 4/100
analysis, leading to actionable AP placement adjustments. Reference: WLSD Study
Guide — Wireless
Site Survey Methodology, Layer 1 Spectrum Analysis, Interference Identification
and Mitigation.
Question: 4
An engineer must identify the network requirements for a company that has a main
office and 10
branch offices. The network must be able to support data, voice, video, and
location tracking. Which
two factors must be considered? (Choose two.)
A. security policy of the company for building access
B. number of wireless devices that require access
C. type of site for which the survey will be performed
D. business type of the company
E. available power sockets in the IT room
Answer: B, C
Explanation:
When designing a wireless network to support diverse services — including data,
voice, video, and
location tracking — across a distributed enterprise with a main office and 10
branch locations, the
two primary design factors directly shaping the RF and capacity architecture are
the number of
wireless devices requiring access and the type of site where the survey will be
performed. The device
count (Option B) drives AP density, channel reuse planning, capacity modeling,
and controller
licensing requirements. Each service type — particularly VoWLAN and video —
imposes strict perclient
throughput and latency constraints that must be multiplied across the concurrent
device
population. The type of site (Option C) determines the survey approach,
attenuation characteristics,
coverage requirements, and antenna selection. A warehouse, hospital, or
open-plan office each
demands a fundamentally different RF design. Options A and D are organizational
considerations, not
technical RF design inputs. Option E (power sockets) is an installation
logistics concern, not a wireless
design factor. Reference: WLSD Study Guide — Requirements Gathering, Site Survey
Planning,
Capacity and Coverage Design Methodology.
Question: 5
A small customer has a legacy autonomous mode Wi-Fi deployment that provides a
low-density and
low-capacity service. The customer wants to update and replace this deployment
with the latest Wi-
Fi technology but has a fixed budget that will pay only to replace the APs.
Which architectural
controller deployment model suits this requirement?
A. embedded
B. unified
C. fabric
D. cloud
Answer: A
Explanation:
Cisco's Embedded Wireless Controller (EWC) architecture is the ideal solution
for small deployments
with strict budget constraints where only the access points can be replaced. EWC
is a controller
function that runs directly within the Cisco Catalyst 9100 Series access point
itself — eliminating the
need for a dedicated physical or virtual WLC appliance. The APs serve dual roles
as both the wireless
radio infrastructure and the controller platform. The unified model (Option B)
requires a dedicated
hardware WLC such as the 9800 series, exceeding the customer's budget. Fabric
(Option C) requires
Cisco DNA Center and SD-Access infrastructure, making it cost-prohibitive for a
small deployment.
Cloud (Option D) requires ongoing subscription fees that may not fit a fixed
one-time budget. EWC
provides enterprise-grade features including centralized SSID management, RRM,
and client mobility
within the AP cluster — all without additional controller hardware investment.
This makes it the
canonical solution for SMB migrations from autonomous deployments. Reference:

and Branch Wireless Design.
