Question: 2Given: An ingress frame happens to the Ethernet convey of an autonomous AP marked along with an IEEE802.1D customer important agenda value.Which IEEE 802.1D end user concern valuations (by name) will guarantee the images payload maintained by theEthernet figure obtains designated to the highest important agenda WMM queue?
A. Controlled LoadB. Network ControlC. VideoD. VoiceE. Best EffortF. Excellent Effort
Answer: B, D
Question: 3Given: When the postponed Block Ack protection plan must be used concerning not one but two QoS STAs, the actual receiver mustrespond to a BlockAckReq shape along with an ACK frame. The receiver should then mail it's BlockAckresponse shape within a eventually obtained TXOP.Once the contents in the BlockAck frame are actually prepared, the particular recipient must_______________.
A. Send that BlockAck response mode to be able to the particular originator in the original probable TXOP with the best priority AC.B. Send an ATIM towards originator symbols of that the BlockAck result style is usually completely ready for transmission.C. Include the TID involving the BlockAckReq within the subsequent TXOP Request into the HC.D. Wait for just one PIFS after the future Beacon in addition to transmit the particular BlockAck reaction on the originator while using the very same AC because the BlockAckReq frame.
Question: 4A QoS STA acquires a TXOP for a strong access category (AC) after just what exactly two guidelines tend to be met?
A. After a already signed company period of time endsB. The low to medium is usually lazy at the AIFS[AC] position boundaryC. The backoff moment with the AC has expiredD. After a new Block ACK ResponseE. After some sort of Target Beacon Transmission Time (TBTT)
Answer: B, C
Page one particular involving 66Question: 5When making use of a standard protocol analyzer that will seize chats over a WLAN, you may generally encounterencrypted info frames. Most WLAN standard protocol analyzers possess a attribute that allows the analyst tosave and reload this seized glasses into storage area with a subsequently time. Using that functionality, whattask might be performed?
A. When IEEE 802.1X/LEAP will be being exercised as being the WLAN security mechanism, that authentication response frame might be replayed coming from a unspent trace record in the later time frame for you to productively authenticate some sort of hacker.B. If your end user brand and also password to get an IEEE 802.1X/EAP-TTLS safety rendering could always be acquired by way of sociable anthropological tactics, a computer owner appoint and also password might be typed in to the analyzer in order to decrypt the actual glasses from the stored search for file.C. An analyst can seek throughout the harnessed eyeglasses looking for RADIUS casings that can disclose this user's password.D. Encrypted casings could often be decrypted offline, after they are captured, by means of getting into a new WEP critical as well as WPA passphrase in the analyzer.
Question: 6How long, throughout microseconds, may be the recommended Slot Time publicised by an AP in an ERP BSS whenboth HR-DSSS as well as ERP-OFDM buyer gas stops are connected towards AP?
A. 2B. 4C. 9D. 10E. 20
Question: 7The IEEE 802.11 standard makes it possible for to get figure fragmentation. Which a couple career fields while in the IEEE 802.11frame are involved in numbering records shape fragments and notifying this receiving train station as soon as allof the actual fragments of an facts shape are already received?
A. Capability Information fieldB. Frame Control fieldC. ERP Information fieldD. Sequence Control fieldE. DS Parameter fieldF. Ordered Service field
Answer: B, D
Question: 8According for the IEEE 802.11 standard (as amended), transmit power data is carried inwhich frames?
A. TPC Report frameB. ADDTS Response frameC. Probe Response frameD. Beacon frameE. Channel Switch Announcement frameF. Measurement Report frame
Page only two involving 66Answer: A, C, D
Question: 9What incidents may cause a well accredited TSPEC that will be gone by way of AP?
A. Disassociation from the non-AP QoS STA using the TSPEC from the QoS BSSB. Traffic Stream inactivity timeoutC. Reassociation of the non-AP QoS STA by using another QoS APD. Receipt of an DELBA shape from a non-AP QoS STAE. Receipt connected with an Update TSPEC figure from the non-AP QoS STAF. A Controlled Access Phase (CAP) burst
Answer: A, B, C
Question: 10Many autonomous entry items help support IEEE 802.1Q VLAN tagging. When studying some sort of WLANsystem implementing IEEE 802.1Q tags, wherever might the actual VLAN tag amount end up being seen?
A. In your Sequence Control area from the MSDUB. In the PLCP header's Service fieldC. In the actual Frame Control discipline from the MPDU headerD. In the particular Ethernet header for the wired opening from the admittance pointE. In the Beacon Management frame's Capabilities fixed field
Question: 11Given: ABC Company is implementing a new QoS enabled infrastructure that will service together voiceand data. The WLAN controlled will be connected to probably about three main layer-3 Ethernet switches. Eachcore layer-3 Ethernet switch provides various advantage layer-2 Ethernet goes attached. LightweightAPs are linked to all or any borders layer-2 Ethernet switches. The WLAN controller will be on subnet10.1.1.0/24, as well as APs are about many different subnets. The APs will be attached on the WLANcontroller by means of LWAPP tunnels.When IEEE 802.11 structures get to some sort of light-weight AP coming from a QoS STA this ought to be delivered to theWLAN controller, which in turn pieces can the particular AP recognise in order to transmission this layer-2 as well as layer-3 Ethernet switchesto employ greater priority processing?
A. The Ethernet frame's 802.1Q priority licence plate bitsB. The IP header's TOS bitsC. The IEEE 802.11 frame's QoS Control bitsD. The LWAPP header's C bitE. The UDP header's PRI bits
Answer: A, B
