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.

Topic 4

WLAN Medium Access: The exam evaluates the understanding of a wireless network professional about 802.11 contention algorithms and their impact on WLAN performance. The CWAP-404 exam requires candidates to analyze QoS configurations and operations.

Topic 5

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.

NEW QUESTION # 115
In what scenario is Open Authentication without encryption not allowed based on the 802.11 standard?

A. When operating a BSS in a government facility
B. When operating a BS5 in the CBRS band
C. When operating a BSS in FIPS mode
D. When operating a BSS in the 6 GHz band

Answer: D

Explanation:
Explanation
Open Authentication without encryption is not allowed when operating a BSS in the 6 GHz band, according to the 802.11 standard. Open Authentication is a type of authentication method that does not require any credentials or security information from a STA (station) to join a BSS (Basic Service Set). Open Authentication can be used with or without encryption, depending on the configuration of the BSS and the STA. Encryption is a technique that scrambles the data frames using an algorithm and a key to prevent unauthorized access or eavesdropping. However, in the 6 GHz band, which is a newly available frequency band for WLANs, OpenAuthentication without encryption 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. The other options are not correct, as they do not describe scenarios where Open Authentication without encryption is not allowed by the 802.11 standard. When operating a BSS in the CBRS band, which is another newly available frequency band for WLANs, Open Authentication without encryption is allowed, but not recommended, as it also poses security and interference risks for other users and services in the band. When operating a BSS in FIPS mode, which is a mode that complies with the Federal Information Processing Standards for cryptographic security, Open Authentication without encryption is allowed, but not compliant, as it does not meet the FIPS requirements for encryption algorithms and keys. When operating a BSS in a government facility, Open Authentication without encryption is allowed, but not advisable, as it may violate the government policies or regulations for wireless security.

NEW QUESTION # 116
You are responsible for troubleshooting and analysis of the WLAN in your organization that supports more than 700 client STAs. Forty APs are deployed and they are all dual-band APs and are controller-based. You must troubleshoot the wired side in some scenarios using a protocol analyzer. Which one of the following problems would warrant wired-side analysis in most situations?

A. High 802.11 retry rates
B. DHCP problems
C. WMM QoS issues
D. High 802.11 CRC rates

Answer: B

Explanation:
DHCP problems would typically warrant wired-side analysis because DHCP transactions primarily occur over the wired network between the APs and the DHCP server. Issues such as IP address assignment failures or delays are often related to misconfigurations or network issues on the wired infrastructure, so troubleshooting with a protocol analyzer on the wired side is essential.

NEW QUESTION # 117
How is the length of an AIFS is calculated?

A. DIFS + SIFS + AIFSN
B. AIFSN * Slot Time + SIFS
C. SIFS * Slot Time + AIFSN
D. SIFS + AIFS * Time Unit

Answer: B

Explanation:
The length of an AIFS (Arbitration Interframe Space) is calculated by multiplying the AIFSN (Arbitration Interframe Space Number) by the Slot Time and adding the SIFS (Short Interframe Space). An AIFS is a variable interframe space introduced by 802.11e to help prioritize medium access for different Access Categories (ACs). An AC is a logical queue that corresponds to a QoS (Quality of Service) level for different types of traffic. Each AC has a different AIFSN value, which determines how long it has to wait before attempting to access the medium. A lower AIFSN value means a higher priority and a shorter waiting time. The Slot Time is a fixed value that depends on the PHY type and channel width. The SIFS is the shortest interframe space that is used for high-priority transmissions, such as ACKs or CTSs. The formula for calculating the AIFS length is: AIFS = AIFSN * Slot Time + SIFS.

NEW QUESTION # 118
Which one of the following is not an 802.11 Management frame?

A. PS-Poll
B. Authentication
C. Action
D. Beacon

Answer: A

Explanation:
A PS-Poll (Power Save Poll) frame is not an 802.11 management frame. A PS-Poll frame is a type of control frame that is used by a STA in power save mode to request data frames from an AP. A STA in power save mode can conserve battery power by periodically sleeping and waking up. 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 PS-Poll frame to the AP, indicating its association ID and requesting any buffered data frames. The AP then responds with one or more data frames, followed by an ACK or BA frame from the STA. The other options are not correct, as they are types of 802.11 management frames. An Action frame is used to perform various management actions, such as spectrum management, QoS management, radio measurement, etc. A Beacon frame is used to advertise the presence and capabilities of an AP or BSS. An Authentication frame is used to establish or terminate an authentication relationship between a STA and an AP.

NEW QUESTION # 119
An HT STA does not receive an ACK for a first-attempt data frame that it transmitted. Assuming this STA is not using BlockAcks in this case, what happens to the HT STA's EDCA contention window?

A. It varies because the backoff algorithm is random.
B. The contention window approximately doubles in size.
C. The slot time within the contention window decreases by 50%.
D. The contention window is immediately closed, and the frame is retransmitted.
E. The contention window is not affected by failed Data frame delivery.

Answer: B
