CWNP CWAP-404 Exam Syllabus Topics:

Topic
Details

Topic 1

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.

Topic 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.

Topic 3

Frame Exchanges: The topic evaluates the skills of a wireless network professional in capturing, understanding, and analyzing various frame exchanges, including BSS discovery, joining, roaming, and data frames. The CWAP-404 Exam targets the ability of candidates to troubleshoot and resolve issues related to MAC layer operations, ensuring they can maintain robust and efficient WLAN communications.

CWNP Certified Wireless Analysis Professional Sample Questions (Q166-Q171):

NEW QUESTION # 166
How many frames are exchanged for 802.11 authentication in the 6 GHz band when WPA3- Enterprise is not used, and a passphrase is used instead?

A. 0
B. 1
C. 2
D. 3

Answer: A

Explanation:
Two frames are exchanged for 802.11 authentication in the 6 GHz band when WPA3-Enterprise is not used, and a passphrase is used instead. Authentication is a process that establishes an identity relationship between a STA (station) and an AP (access point) before joining a BSS (Basic Service Set). There are two types of authentication methods defined by 802.11: Open System Authentication and Shared Key Authentication. Open System Authentication does not require any credentials or security information from a STA to join a BSS, and it consists of two frames: an Authentication Request frame sent by the STA to the AP, and an Authentication Response frame sent by the AP to the STA. Shared Key Authentication requires a shared secret key from a STA to join a BSS, and it consists of four frames: two challenge-response frames in addition to the request-response frames. However, Shared Key Authentication uses WEP (Wired Equivalent Privacy) as its encryption algorithm, which is insecure and deprecated. In the 6 GHz band, which is a newly available frequency band for WLANs, Shared Key Authentication is prohibited by the 802.11 standard, as it poses security and interference risks for other users and services in the band. The 6 GHz band requires all WLANs to use WPA3- Personal or WPA3- Enterprise encryption methods, which are more secure and robust than previous encryption methods such as WPA2 or WEP. WPA3-Personal uses a passphrase to derive a PMK (Pairwise Master Key), while WPA3-Enterprise uses an authentication server to obtain a PMK. Both methods use SAE (Simultaneous Authentication of Equals) as their authentication protocol, which replaces PSK (Pre-Shared Key) or EAP (Extensible Authentication Protocol). SAE consists of two frames: an SAE Commit frame sent by both parties to exchange elliptic curve parameters and nonces, and an SAE Confirm frame sent by both parties to verify each other's identities and generate a PMK. Therefore, when WPA3-Enterprise is not used, and a passphrase is used instead in the 6 GHz band, only two frames are exchanged for 802.11 authentication: an SAE Commit frame and an SAE Confirm frame.

NEW QUESTION # 167
You view a protocol analyzer capture decode with the following protocol frames listed in the following order (excluding the ACK frames):
1) 802.11 Probe Request and 802.11 Probe Response
2) 802.11 Auth and another 802.11 Auth
3) 802.11 Assoc Req and 802.11 Assoc Rsp
4) EAPOL-Start
5) EAP Request and EAP Response
6) EAP Request and EAP Response
7) EAP Request and EAP Response
8) EAP Request and EAP Response
9) EAP Request and EAP Response
10) EAP Success 19) EAPOL-Key (4 frames in a row)
What are you seeing in the capture file?

A. Wi-Fi Protected Setup with PIN
B. WPA2-Personal authentication
C. WPA2-Enterprise authentication
D. 802.1X with Dynamic WEP

Answer: C

NEW QUESTION # 168
A manager at a retail outlet has complained that an incident occurred allowing a STA to launch an attack against another STA connected to their public Wi-Fi hotspot. He has asked you to troubleshoot the situation and verify that all possible measured are being taken to prevent this.
What configuration should you check in the AP?

A. Client-to-client direct communications
B. DNS settings
C. Captive portal Internet gateway
D. Inter-VAP filtering

Answer: A

Explanation:
Disabling client-to-client communication (also known as peer-to-peer or "AP isolation") prevents devices connected to the same wireless network from communicating directly with each other.
This helps mitigate attacks where one client station (STA) could attack another STA, such as through ARP spoofing or other local network-based attacks.

NEW QUESTION # 169
When using a commercial WLAN protocol analyzer, you notice that it is listing vendor names for some APs and client STAs.
What is the source of this information?

A. DNS name resolution
B. Banner grabbing
C. Vendor OUI values
D. Broadcast name resolution

Answer: C

NEW QUESTION # 170
According to the 802.11n-2009 amendment, what security requirement is specified for HT BSSs?

A. HT BSSs must mandatorily support 802.11r FT.
B. In an RSN, HT stations may not communicate with one another using TKIP.
C. HT BSSs are prevented from supporting WEP.
D. All unicast traffic transmitted by an HT station and destined to an HT station must use AES- CCMP.
E. TKIP cannot be supported in an HT BSS.

Answer: B
