ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.
In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?
- A . Have only guest access on the 5 GHz channels.
- B . Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.
- C . Use captive portals for guest authentication in 5 GHz.
- D . Implement WPA-PSK everywhere in the network.
What advantages are provided by per-user PSKs when compared with ESS-wide PSKs? (Choose all that apply.)
- A . Per-user PSKs allow easier user-based access control with WPA/WPA2-Personal security.
- B . Per-user PSKs are easier to manage if a PSK is compromised or an employee leaves a company.
- C . Per-user PSKs are standardized and certified by the Wi-Fi Alliance.
- D . Per-user PSKs are more secure than ESS-wide PSKs because they support mutual authentication.
For what purposes are VPNs typically used in modern WLANs? (Choose all that apply.)
- A . Remote AP tunneling to a corporate WLAN controller or VPN concentrator
- B . Client device connectivity to corporate resources from unsecured public networks
- C . Initial 802.11 authentication with the AP and subsequent data encryption
- D . Tunneling APs and WLAN controllers to cloud-based management platforms
- E . Tunneling APs and WLAN controllers to RADIUS and token servers
- F . Bridging client connectivity in ad hoc networks
You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for best performance.
Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?
- A . – 75 dBm
- B . – 72 dBm
- C . – 67 dBm
- D . – 62 dBm
What method improves throughput in a low SNR environment?
- A . 64-QAM
- B . A-MSDU frame aggregation
- C . Receive diversity
- D . SM
What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags?
- A . When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.
- B . Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.
- C . With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.
- D . Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag reader to communicate tag information to the
After designing a WLAN infrastructure using predictive design software.
What’s the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?
- A . Deploy all of the APs as they’re shown in the predictive design and perform an active site survey.
- B . Deploy all of the APs as they’re shown in the predictive design and perform a passive site survey.
- C . Use a client device positioned where the APs will be installed and measure the signal from the client device.
- D . Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP’s placement.
Your customer requires a security solution in which client credentials are used and the authentication server must have a certificate with optional client certificate use.
Which EAP method would be the best fit for their requirement?
- A . EAP-FAST
- B . EAP-TTLS
- C . EAP-TLS
- D . LEAP
A wireless engineer from your company performed a site survey in an office building where a wireless network extension was needed. He reports that while performing a Layer 1 sweep near a meeting room full of people, he detected RF activity with a very low duty cycle. He is unsure how to interpret what he recorded to determine its impact on a future Wi-Fi network.
What is true about this RF environment and its potential impact on the WLAN?
- A . The signal affects the entire spectrum and will render the wireless network unusable. It must be located and removed.
- B . The signal has a low duty cycle and should not be of major impact on the wireless network.
- C . The signal is alternating between peaks (high interference level) and valleys (low interference level). The network channel design must be built to avoid the affected peak frequencies.
- D . The signal is typical of a high radio card background noise. It shows that the card used for the Layer 1 sweep should be replaced and the Layer 1 sweep re-
Given:
In your regulatory domain, a Tx Power Level of "1" is equivalent to 17 dBm.
For every integer increment (e.g. from 1 to 2) to the Tx Power Level, the APs transmit power is halved.
In units of mW, what is the actual transmit power for an AP configured at a Tx Power Level of "4"?
- A . 6.25 mW
- B . 50 mW
- C . 12.5 mW
- D . 8 mW
