What is an advantage of centralized data forwarding?

• It reduces delay for user traffic
• It increases the encryption strength for user traffic
• It increases the signal strength for wireless client devices
• It allows for centralized filtering of wireless traffic

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?Response:

• 17 dBm
• 125 mW
• 11 dBm
• 6.25 mW

What type of protection should be provided to outdoor antenna installations? Response:

• Static electricity
• Brownouts
• Lightning surge suppression
• A/C spikes

An engineering firm upgraded from nine 802.11n APs to nine 802.11ac APs, retaining the same channel and power configuration. Despite this, throughput remains unchanged. What is the most likely reason for the lack of improvement?

• APs are transmitting at a low transmit power
• The clients were not upgraded
• APs are mounted on the wall
• The APs are still using the 5 GHz lower band

When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USBspectrum analysis adapters to collect RF spectrum data. Since your laptop doesn't have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?

• It does not give you enough bandwidth to collect data coming from all of the adapters.
• It does not give you enough power for all four of your adapters.
• It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
• It generates noise in the 5 GHz band, giving you a false perception of the noise floor.

In most WLAN design tools, after defining project parameters or during the project creation wizard what action will you take before you can begin the actual design process?

• Place APs
• Define cabling
• Import a floor plan
• Define wall materials

For what purpose is SSID hiding generally useful?(Choose all that apply.) Response:

• Preventing guests from attempting to join the secured corporate network
• Obscuring the network name from potential attackers
• Minimizing help desk calls from users and guests attempting to join the wrong network
• Preventing legitimate corporate users from finding the guest network

What are some advantages of designing guest access with all guest users tunneled directly into the DMZ?Response:

• Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN
• Enhances performance of web proxy servers in the DMZ for guest Internet traffic
• Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests
• The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller

What kind of site survey helps you identify if roaming is working as designed?

• Passive
• Predictive
• Active
• Spectrum analysis walkthrough

What power management feature introduced in 802.11ax, but not available in 802.11ac or 802.11n, is designed to improve battery life for WLAN devices?

• WMM-Power Save
• Legacy Power Save
• TWT
• OFDMA
