CWNA-109 practice questions, page 4 of 5, with answer review and explanations.
Question 16
Your consulting firm has recently been hired to complete a site survey for a company desiring an indoor coverage WLAN. Your engineers use predictive design software for the task, but the company insists on a pre-design site visit. What task should be performed as part of the pre-design visit to prepare for a predictive design?
Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls
Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers
Evaluate the building materials at the facility and confirm that the floor plan documents are consistent with the actual building
Test several antenna types connected to the intended APs for use in the eventual deployment
Question 17
You are attempting to explain RF shadow and how it can cause lack of coverage. What common building item frequently causes RF shadow and must be accounted for in coverage plans?
Elevators
Carpeted floors
Cubicle partitions
Wooden doors
Question 18
Which unit of measurement, as formally defined, is an absolute unit that is used to quantify received signal power levels on a logarithmic scale?
SNI
VSWR
dBm
dBi
Question 19
What fact is true regarding controllers and APs in a split-MAC architecture?
With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator
An IP tunnel is established between the AP and controller for AP management and control functions
Using centralized data forwarding, frames leaving the APs are never tagged Ethernet frames with VLAN identifiers
All data must be sent to a cloud provider and then back to the local network
Question 20
What feature of 802.11ax (HE) is managed with beacon and trigger frames and is primarily a power management method, but also provides more efficient access to the channel used within a BSS?
