QUESTION 121
A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel’s SSID and notices an AP in the hotel room.
However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby.
What would be the most likely cause of the low RSSI in the hotel room?
Response:

QUESTION 122
In a convention center, you have received complaints about the WLAN infrastructure. At this moment, the are only two APs in one auditorium. After analyzing the situation, you determined that there are more client devices that the infrastructure was designed for. There are only two APs to support more than 300 devices using the Wi-Fi at the same time. What should you do to make the Wi-Fi work as expected?

QUESTION 123
During a validation site survey, you realize that the installers mounted some of the APs on the wait when the design called Tor a celling mount. They said that this was done because the cabling company did not have the right tools to run the cables above the ceiling. You know that this will cause a difference in how the Wi-Fi signal will radiate throughout the environment. What should you do in this case?

QUESTION 124
During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine.
What’s the likely cause of this issue?

QUESTION 125
Your customer’s 802.11n laptops cannot detect the SSID in the 5 GHz band in a conference room, but your 802.11ac laptop connects without issue. What is the most likely explanation for this discrepancy?

QUESTION 126
What best describes ensuring coverage requirements in a deployed WLAN?

QUESTION 127
What frequency and power did 802.11y provide?
Response:

QUESTION 128
During a validation site survey, you discover that some access points (APs) have been mounted above the ceiling due to an aesthetic request from the building architect. However, no aesthetics constraints were communicated during the requirements gathering from the main stakeholder of the project. What is the appropriate course of action?

QUESTION 129
What advantage provided by 802.11n and 802.11ac is not usable in 1×1:1 low-end client devices?

QUESTION 130
You have performed a validation site survey after deploying a WLAN infrastructure in an All-Wireless-Office. One specific application is experiencing delays after transitioning from wired to wireless connectivity. During validation, you discover that all APs are using 80 MHz channel widths instead of the designed 20 MHz on the 5 GHz band. What can be done to resolve the delay for this application?

QUESTION 131
When installing a cloud-based AP, what is the most common process used?
Response:

QUESTION 132
When a WLAN controller sends an 802.11 frame to a lightweight AP for transmission on the wireless medium, how does it mark the frame for 802.11 QoS priority?

QUESTION 133
Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4×4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?

QUESTION 134
While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure.
What should you do to prevent this?

QUESTION 135
When performing an active site survey in an existing WLAN infrastructure, in addition to gathering throughput data, what other important function will you typically be testing at the same time?

QUESTION 136
You are selecting external antennas for use in a bridge link deployment. What chart should you request from the antenna vendors to make an accurate selection?

QUESTION 137
What kind of antenna results in a nearly circular pattern on the azimuth chart but a very flat donut shape on the elevation chart?
