질문 # 137
Which bit in a neighboring BSS's Beacon frame will trigger an AP to enable protection mechanism?
정답:A
설명:
The Non-ERP Present bit in a neighboring BSS's Beacon frame indicates that legacy 802.11b devices are present. APs use this information to enable protection mechanisms (such as RTS/CTS or CTS-to-Self) to prevent collisions and ensure coexistence with legacy clients.
질문 # 138
How does a VoIP Phone, using WMM Power Save, request data frames buffered at the AP?
정답:A
설명:
A VoIP phone, using WMM Power Save, requests data frames buffered at the AP by transmitting a trigger frame, which is a QoS Null frame or a QoS Data frame. WMM Power Save is a power saving mode that allows a STA (station) to conserve battery power by periodically sleeping and waking up. WMM Power Save is based on WMM (Wi-Fi Multimedia), which is a QoS (Quality of Service) enhancement that provides prioritized and differentiated access to the medium for different types of traffic. When a STA sleeps, it cannot receive any data frames from the AP, so it informs the AP of its power save status by setting a bit in its MAC header. The AP then buffers any data frames destined for the sleeping STA until it wakes up. When a STA wakes up, it sends a trigger frame to the AP, indicating its AC (Access Category), which is a logical queue that corresponds to its QoS level. A trigger frame can be either a QoS Null frame or a QoS Data frame, depending on whether it has any payload or not. The AP then responds with one or more data frames from the same AC as the trigger frame, followed by an ACK or BA (Block Acknowledgement) frame from the STA.
The other options are not correct, as they are not used by a VoIP phone using WMM Power Save to request data frames buffered at the AP. A PS-Poll (Power Save Poll) frame is used by a STA using legacy power save mode, not WMM Power Save mode, to request data frames buffered at the AP. A PS-Poll frame does not indicate any AC or QoS information. Setting the More Data bit in the MAC header to 1 does not request any data frames from the AP, but indicates that there are more data frames to be sent by the STA or received by the STA. Transmitting a WMM Action frame does not request any data frames from the AP, but performs various management actions related to WMM features, such as admission control, parameter update, etc. References: [Wireless Analysis Professional Study Guide CWAP-405], Chapter 7: QoS Analysis, page
198-199
질문 # 139
Which one of the following is not a valid acknowledgement frame?
정답:B
설명:
An RTS frame is used to request access to the medium and initiate an RTS/CTS exchange. It does not acknowledge receipt of a previous frame. CTS, Ack, and Block Ack are all valid acknowledgment mechanisms used to confirm receipt of transmissions.
질문 # 140
A PHY Header is added to the PSDU at which layer?
정답:B
설명:
A PHY header is added to the PSDU at the PHY layer. A PHY header is a part of the PPDU that contains information such as modulation, coding, and data rate. The PHY header is added by the PHY layer when it converts a PSDU to a PPDU for transmission, or removed by the PHY layer when it converts a PPDU to a PSDU for reception. The other layers do not add or remove a PHY header. References: [Wireless Analysis Professional Study Guide CWAP-405], Chapter 4: 802.11 Physical Layer, page 97-98
질문 # 141
An RTS frame should be acknowledged by which frame?
정답:C
설명:
An RTS frame is acknowledged with a CTS frame as part of the RTS/CTS exchange mechanism.
The CTS confirms that the medium is reserved and allows the sender to proceed with transmitting the data frame.
