CWNP CWAP-404 Prüfungsplan:

Thema
Einzelheiten

Thema 1

Spectrum Analysis: The topic assesses the ability of a wireless network professional to capture and interpret RF spectrum data. The exam targets the skills in identifying device signatures and RF issues through spectrum analyzers.

Thema 2

MAC Sublayer and Functions: The topic measures the ability of a wireless network professional to understand and analyze the MAC layer operations. Candidates are expected to validate BSS configurations and identify issues like CRC errors and retransmissions, ensuring they can maintain the integrity and performance of the WLAN.

Thema 3

Protocol Analysis: The topic in the CWNP CWAP-404 exam evaluates the skill of a wireless network professional to capture and analyze 802.11 frames effectively. Candidates must demonstrate proficiency in configuring protocol analysis tools, interpreting frame captures to diagnose issues, and applying appropriate troubleshooting methods.

CWNP Certified Wireless Analysis Professional CWAP-404 Prüfungsfragen mit Lösungen (Q41-Q46):

41. Frage
Why would a STA that supports 802.11k Radio Measurement send a Neighbor Request to an AP?

A. To request a list of neighboring APs which the STA can use as roaming candidates
B. To inform the current AP about the STA's intent to roam to a neighboring AP, ensuring a seamless handover
C. To request a list of neighboring STAs which enables the STA to better pick the right protection mechanisms
D. To learn about neighboring interference sources and tune its RF radio accordingly

Antwort: A

Begründung:
Explanation
A STA that supports 802.11k Radio Measurement would send a Neighbor Request to an AP to request a list of neighboring APs which the STA can use as roaming candidates. A Neighbor Request is an Action frame that contains a subelement specifying the type of information that the STA wants to receive from the AP. A Neighbor Report is an Action frame that contains a subelement with a list of neighboring APs that match the criteria specified in the Neighbor Request. The Neighbor Report provides information such as BSSID, channel, operating class, and PHY type of each neighboring AP. This information helps the STA to perform intelligent roaming decisions based on signal quality, load, and compatibility .

42. Frage
When performing protocol analysis, you capture an 802.11ac data frame on channel 52, transmitted at MSC 8.
At what data rate was the PHY Preamble transmitted?

A. 54 Mbps
B. 6 Mbps
C. 86.7 Mbps
D. 78 Mbps

Antwort: B

Begründung:
The transmitter sends the preamble at 1 Mbps (802.11 or 802.11b DSSS) or 6 Mbps (802.11a or
802.11g ERP-OFDM).

43. Frage
When a data frame is encrypted with WPA2, to which portion of the frame is the encryption applied?

A. Frame body including the LLC
B. Frame body excluding the LLC
C. Frame body and MAC Header
D. The whole MPDU

Antwort: A

Begründung:
When a data frame is encrypted with WPA2, the encryption is applied to the frame body including the LLCPDU. The LLCPDU (Logical Link Control Protocol Data Unit) is a part of the frame body that contains information such as protocol type, source and destination service access points (SAPs), and control fields. The LLCPDU is added by the LLC (Logical Link Control) sublayer to provide multiplexing and flow control functions for different upper layer protocols. When a data frame is encrypted with WPA2, which uses AES-CCMP as its encryption algorithm, both the payload and the LLCPDU are encrypted as a single unit. The MAC header and FCS are not encrypted, as they are needed for addressing and error detection purposes.

44. Frage
Given: Protocol analyzer often have useful graphical dashboards providing information about the health and operations of the WLAN.
What is a valid use of a graph showing the Top APs Based on Active Associations?

A. Locating overloaded APs
B. Discovering the total number of client STAs on your network
C. Ensuring compliance with corporate security policies
D. Evaluating the capacity handling on a specific channel

Antwort: A

45. Frage
When an originator QoS STA initiates a BlockAck agreement with a recipient QoS STA, what is the first frame sent by the originator?

A. ActionBAReq
B. BlockAckReq
C. ADDBA Request
D. BlockAckSetupReq
E. BlockAckPolicyReq

Antwort: C
