CWNP CWDP-304 Online Questions & Answers

• Question 151:

  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 effective at 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 152:

  You are working on a VoWLAN design with your customer's wired networking team. How many distinct priority levels do you expect for the voice applications?

  A. 1 priority level, but 2 queues (one for uplink traffic, one for downlink traffic)
  B. 1 priority level per client and AP pair, so the total number depends on the expected number of clients
  C. 1 priority level for voice RTP, 1 priority level for voice control and RTCP
  D. 1 priority level for VoWLAN client traffic, 1 priority level for wired VoIP client traffic
  C. 1 priority level for voice RTP, 1 priority level for voice control and RTCP

• Question 153:

  How much more power can a 1 Mbps 802.11b signal have than a 54 Mbps 802.11g signal if it is sent through a saturated amplifier? Response:

  A. 5 dBm
  B. 2 dBm
  C. 2 dB
  D. 5 dB
  D. 5 dB

• Question 154:

  When doing some frame capturing over the air during a voice call, you realized that frames on the downlink (from the AP to the client) direction are not being transmitted with the correct UP value for voice frames, but on the uplink (from the client to the AP) direction are being transmitted correctly. What's the cause of this issue?

  A. Bad client driver
  B. AP is not receiving enough PoE, thus not using QoS features
  C. Somewhere on the wired network QoS markings aren't being trusted
  D. Faulty antenna on the AP
  C. Somewhere on the wired network QoS markings aren't being trusted

• Question 155:

  During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS. This frame is typical of those that were captured by the analyzer.

  What does this frame reveal about the RF network in this area?

  A. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
  B. Contention Free is in place in this network, which may starve some non-QoS stations from access
  C. Multipath or excessive collisions seem to be an issue in this area
  D. The AP seems to be too far to provide enough coverage to this area
  C. Multipath or excessive collisions seem to be an issue in this area

• Question 156:

  What advantages are provided by per-user PSKs when compared with ESS-wide PSKs?(Choose all that apply.) Response:

  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.
  B. Per-user PSKs are easier to manage if a PSK is compromised or an employee leaves a company.

• Question 157:

  Name the audience type not addressed in this chapter for HLDs. Response:

  A. Operations
  B. Executives
  C. Designers
  D. Engineering
  A. Operations

• Question 158:

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

  A. Configure the AP as an autonomous AP and then, when it connects to the cloud, it will be reconfigured.
  B. Configure a profile for the AP in the cloud and then connect it for automatic configuration.
  C. Connect the AP to the network and configure it from the cloud assigning a configuration or policy set to the AP.
  D. Configure the AP with a local controller and then, when it connects to the cloud, it will be reconfigured.
  B. Configure a profile for the AP in the cloud and then connect it for automatic configuration.

• Question 159:

  An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB.

  Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?

  Response:

  A. 5 dBm
  B. 0 dBm
  C. #5 dBm
  D. 10 dBm
  B. 0 dBm

• Question 160:

  In a multiple channel architecture (MCA) network supporting 802.1X authentication, what aspect of WLAN design affects client roaming efficiency and effectiveness?

  A. PHY standard used by the AP
  B. Key caching protocols
  C. Cipher suite
  D. PHY standard used by client
  B. Key caching protocols
