    New Updated  PW0-250 Exam Questions from AmazonExam PW0-250 pdf dumps! Welcome to download the newest AmazonExam dumps:PW0-250 http://www.amazonexam.com/PW0-250.html

    QUESTION 1
    Multicast video applications typically require special treatment on the Wi-Fi network due to the
    nature of multicast traffic. Many vendors implement proprietary multicast-to-unicast conversion for
    this reason. Which of the following is NOT a valid reason for special unicast conversion of
    downlink multicast traffic?
    A. In QoS WLANs, multicast traffic is always assigned to the best effort (AC_BE) transmit queue.
    B. Group addressed downlink frames are not acknowledged on the wireless medium.
    C. Multicast traffic must always be transmitted via omnidirectional antennas.
    D. Frames with a group receiver address must always be sent at a rate in the Basic Rate Set.
    Answer: C
    QUESTION 2
    Given: Assume that music on hold (MOH) features are unicast only. What VoWiFi
    implementations require multicast packet delivery support by the WLAN infrastructure?
    A. All VoWiFi implementations
    B. Push-to-Talk VoWiFi phones
    C. VoWiFi soft phones
    D. FMC phones
    E. Flat (non-VLAN) VoWiFi implementations
    Answer: B
    QUESTION 3
    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
    E. Video conferencing
    F. FTP
    Answer: D
    QUESTION 4
    Given: The 802.11n APs you have selected for your public access deployment support many of
    the PHY and MAC enhancements offered by the 802.11n standard. The AP is single-band (2.4
    GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3×3 802.11n chip that
    supports two spatial streams. What is the maximum MCS rate that could be supported by this
    AP?
    A. 54 Mbps
    B. 65 Mbps
    C. 108 Mbps

    D. 144 Mbps
    E. 150 Mbps
    F. 300 Mbps
    Answer: D
    QUESTION 5
    As an implementation engineer, you have just received initial design specs from a network
    designer for your dual-band 802.11n deployment. The network design documents prescribe the
    following data rate configuration for the 2.4 GHz radio:
    Basic Rates — 5.5, 6, 11, 12 Mbps
    Supported Rates –9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15 What will result from this
    design strategy?
    A. By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force
    802.11b
    clients to use these higher data rates.
    B. Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic
    rates.
    C. HR/DSSS (802.11b) stations will not be able to associate to the service set.
    D. This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory
    data
    rates for 802.11g/n.
    E. MCS 0 will represent the lowest data rate that can be used in the service set.
    Answer: C
    QUESTION 6
    Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your
    aging wireless network infrastructure, as well as some clients, to support 802.11n. In your
    research, you have discovered that your new wireless client devices and infrastructure are
    802.11n, WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices
    are 802.11a/b/g devices that do not support WMM. Given this information, what scenario is
    possible when your company’s employees begin using both types of client devices on the new
    WLAN?
    A. All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all
    stations
    in use on the wireless medium are WMM-PS certified.
    B. The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based
    upon
    their WMM access category, while the non-WMM-PS client devices will continue to use PS-Poll
    frames.
    C. Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client
    devices
    when used with applications that support WMM-PS.
    D. WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the trigger-
    and-delivery
    mechanism, but WMM-PS stations will get priority.
    E. When all STAs are using Power Save features, WMM-PS STAs will experience poor performance

    due to
    PS protection mechanisms.
    Answer: C
    QUESTION 7
    To achieve a 450 Mbps MCS, what 802.11n features (from the numbered list below) are
    required?
    1. Frame aggregation
    2. Short GI
    3. 40 MHz channels
    4. 2 spatial streams
    5. 3 spatial streams
    6. Transmit beamforming (TxBF)
    A. 1, 2, 3, 4
    B. 1, 2, 3, 5
    C. 1, 2, 3, 4, 6
    D. 1, 2, 3, 5, 6
    E. 2, 3, 4
    F. 2, 3, 5
    Answer: F
    QUESTION 8
    You are tasked with designing the WLAN to accommodate certain high density areas on your
    university campus where users are highly transient (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
    associations. The DHCP server is a Windows Server 2008 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
    E. Enable WLAN Controller DHCP relay
    F. Enable mandatory admission control
    G. Set the AES rekey interval to 5 minutes
    H. Set the 802.1X re-authentication timer to 10 minutes
    Answer: D
