A client complains of low data rates on his computer. When you evaluate the situation, you see that
the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and
connects to an 802.11ac AP. Both the client and AP are 2x2:2 devices. What is the likely cause of the
low data rate issue?
A
You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to 2.4
GHz APs, but is does not even see 5 GHz APs. While evaluating the issue, you determine that this
problem is happening for all of the laptops of this model in the organization. Several other tablets
connect on channel 48 and channel 52 in the same work areas. What is the likely problem?
C
In addition to coverage analysis results, what should be included in a post-deployment site survey
report to ensure WLAN users experience acceptable performance?
B
You are troubleshooting a client problem with a 2.4 GHz WLAN connection. The client is experiencing
surprisingly low data rates during the work day. You analyze the workspace outside of business hours
and detect a strong signal with a typical noise floor at the client location. During working hours, the
user works with a laptop in the area and uses an external USB hard drive for continuous data access.
The user also states that the laptop works as expected on her home network. The user working
approximately 8 feet away from this client experiences no problems.
Based on this information, what is the likely cause of the problem?
D
You were previously onsite at XYZs facility to conduct a pre-deployment RF site survey. The WLAN
has been deployed according to your recommendations and you are onsite again to perform a post-
deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that
must be performed?
C
Your manager asked you to locate a solution that allows for centralized monitoring of WLAN
performance over time. He wants a single pane of glass for administration and monitoring of the
solution. What do you recommend?
C
You are troubleshooting a problem with interference from a non-802.11 device. Given that the
device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum
analyzer. You want to view the signal from the interfering device over time to see the activity that is
generating.
What common spectrum analyzer view should you use for this analysis?
B
What is the final step in an effective troubleshooting process?
D
You have received a report of poor wireless connections on the third floor of a building under your
administration. Three individuals have reported the problem. Apparently, the connections are
reporting a strong signal, but the users cannot access the Internet. With the problem identified, what
is the next logical step in the troubleshooting process?
B
You are using a site survey tool for post-implementation validation. You have installed the
appropriate adapter driver and imported a floor plan. Now, you want to take the next step in proper
tool use. What must you do before gathering survey data after the floor plan is imported?
