Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive design software for the task, but the company insists on a pre-deployment site visit.
What task should be performed as part of the pre-deployment visit to prepare for a predictive design?
Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?
ABC Company is planning a point-to-multipoint bridge deployment with standalone (autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux-based RADIUS server will be used for authentication. What device in the bridge implementation acts as the 802.11X Authenticator?
When compared with legacy Power Save mode, how does VHT TXOP power save improve battery life for devices on a WLAN?
Option 43 must be configured to allow access points to locate controllers. In what network service should this option be configured?
When considering data rates available in HT and VHT PHY devices, in addition to the modulation, coding, channel width, and spatial streams, what impacts the data rate according to the MCS tables?
What factor will have the most significant impact on the amount of wireless throughput available to each station within a BSS?
In addition to coverage analysis result, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?
You recently purchased four laptops containing dual-band 802.11ac adapters. The laptops can connect to your 2.4 GHz network, but they cannot connect to the 5 GHz network. The laptops do not show the 5 GHz SSIds, which are different than the 2.4 GHz SSIDs. Existing devices can connect to the 5 GHz SSIDs with no difficulty. What is the likely problem?
You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not used and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network. What should be inspected to verify proper configuration?
In WLAN security, what authentication method always creates Layer 2 dynamic encryption keys?
In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connects the mesh to an Ethernet network?
Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?
You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?
In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping?
When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?
You administer a WLAN that offers a guest SSID of GUESTNWORK. User connect to the GUESTNWORK SSID, but report that they cannot browse the internet. The devices simply report no internet connection. What common problem causes this scenario?
