CWNP CWDP-302 Online Questions & Answers

• Question 1:

  An associated STA detects a new BSS with the sameSSID as the STA's current BSS.The new BSS uses a differentIP subnet than the current BSS.If the STA is configured to use 802.1X/EAP preauthentication, what is likely to occur?

  A. The STA will not attempt to preauthenticate because the new BSS uses a different IP subnet.
  B. The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.
  C. The STA will attempt to preauthenticate and succeed if DHCP is supported on the new subnet.
  D. The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.
  B. The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.

• Question 2:

  You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antenna gain of 5.85 dBd connected through 25 feet of cable with a lossspecification of 4 dB/100 feet. Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?

  A. 10 mW
  B. 14 mW
  C. 20 mW
  D. 25 mW
  D. 25 mW

• Question 3:

  Which definition correctly describes the "local MAC" variation of the centralized WLAN architecture?

  A. All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the WLAN controller along with management and monitoring functions.
  B. PHY functions are performed directly by the AP. MAC functions are divided almost equally between the WLAN controller and the AP, according to the time sensitivity of the feature or service.
  C. The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions or services. The WLAN controller performs all MAC functions and the AP is very simple and lightweight.
  D. All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network services with one another and are managed by a WNMS, so no WLAN controller is used in this architecture.
  A. All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the WLAN controller along with management and monitoring functions.

• Question 4:

  When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed?

  A. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.
  B. The router between the APs and the controller must be made aware of the APs as forwarding client STAs.
  C. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.
  D. Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.
  A. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.

• Question 5:

  Given:

  In your regulatory domain, a Tx Power Levelof "1" is equivalent to 17 dBm.

  For every integer increment (e.g. from 1 to 2) to the Tx Power Level, the AP's 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
  A. 6.25 mW

• Question 6:

  While configuring your site survey software for an upcoming manual survey project, you notice the configuration option for "Network Card Simulation". What is the purpose of such a feature and when would you use it?

  A. This setting allows the site survey software to convert the AP's measured downlink RF data into a simulated data set as if the same data were transmitted by a specific client station. It is useful for determining uplink client performance when clients are located far from APs as well as projecting cell size for ad hoc networks.
  B. Since WLAN adapters are not typically calibrated by manufacturers, this setting is a form of software calibration in which you can calibrate an (uncalibrated) adapter to match one of the calibrated adapters shown in the list. This process improves the reliability of RF data collection and reporting whenuncalibrated adapters are used.
  C. This is the configuration area in which you specify the adapter type that will be used for the site survey so that the survey software can interpret that adapter's reported metrics (based on proprietary formulas) into an RF measurement that is standardized by the survey software and known to its users. This is done for every survey.
  D. The site survey software manufacturer allows you to view the collected RF data as if it were collected by a different type of adapter. This functionality allows you to review survey data to determine how the RF environment will likely look based on the receive sensitivity and other RF capabilities of a specific client adapter.

• Question 7:

  When performing an indoor predictive site survey to make the WLAN planning and design cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?

  A. All simulated APs should be set to 20 MHz channels only.
  B. Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.
  C. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.
  D. Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configuredvendor AP/antenna combinations.
  C. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.

• Question 8:

  As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.

  What application matches this description?

  A. Voice
  B. Email
  C. Skype chat
  D. Video-on-demand
  D. Video-on-demand

• Question 9:

  You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.

  What setting would be most effectiveat achieving this design task?

  A. Set the RTS threshold to 2346 bytes
  B. Set the inactive wireless client timeout (client age-out) to 5 minutes
  C. Set the maximum client limit per radio to 64
  D. Set the DHCP lease for this pool to 20 minutes
  D. Set the DHCP lease for this pool to 20 minutes

• Question 10:

  What kind of antenna results in a nearly circular pattern on the azimuth chart but a very flat donutshape on the elevation chart?

  A. High gain omni-directional
  B. 20 degree vertical yagi
  C. 120 degree horizontal sector
  D. 60 degree horizontal patch
  A. High gain omni-directional
