Question # 1

In an RSN requiring low-latency reassociations and no fast secure roaming protocols, what security solutions are ideal for protecting VoWiFi communication?(Choose all that apply.)

Response:

Options:

WPA2-Personal

WPA-Personal

WPA2-Enterprise

WEP

802.1X/EAP

Discussion 0

Answer:

A, C

Explanation:

WPA2-Personal and WPA2-Enterprise are ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA2-Personal uses a pre-shared key (PSK) to authenticate and encrypt the communication between the VoWiFi device and the access point. WPA2-Enterprise uses 802.1X/EAP to authenticate the VoWiFi device and the RADIUS server, and then derives a unique encryption key for each session. Both WPA2-Personal and WPA2-Enterprise use AES-CCMP as the encryption algorithm, which provides strong security and low overhead. WPA2-Personal and WPA2-Enterprise also support key caching and pre-authentication mechanisms, which reduce the latency and disruption during reassociations. These features are essential for maintaining the quality of service and user experience for VoWiFi communication.

WPA-Personal, WEP, and 802.1X/EAP are not ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA-Personal uses TKIP as the encryption algorithm, which is less secure and more computationally intensive than AES-CCMP. WPA-Personal also does not support key caching and pre-authentication mechanisms, which increase the latency and disruption during reassociations. WEP is an outdated and insecure encryption algorithm that can be easily cracked by attackers. WEP also does not support any authentication or key management mechanisms, which expose the VoWiFi communication to various attacks. 802.1X/EAP is an authentication framework, not a security solution. 802.1X/EAP alone does not provide any encryption or key management for the VoWiFi communication. 802.1X/EAP must be combined with a robust encryption algorithm, such as AES-CCMP, to provide adequate security for VoWiFi communication.

Question # 2

Main Topic:Post-Design ValidationandTroubleshooting

Question:

A cable with 2.5 dB of loss is used to measure the return loss of an antenna. The measured value in-band is shown to be larger than 20 d

What is the actual return loss of the antenna, and is it considered to be a reasonable value?

Options:

Larger than 15 dB and yes

Larger than 15 dB and maybe

Larger than 17.5 dB and yes

Larger than 17.5 dB and no

You are creating an outdoor bridge link that spans more than 1000 yards. Which one of the following antenna types is more likely to be included in the design?

Options:

Yagi

Omni

Patch

Panel

Question # 4

Your customer's 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room. When doing a walkthrough using one of these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using your own 802.11ac laptop, you're able to see the SSI

What is the most likely cause of this problem?

Options:

The AP is configured to use channel 36

The customer laptop does not support Transmit Beamforming

The AP is on channel 144

Their laptops are SISO clients

Question # 5

What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag?

Options:

Lack of 802.11k support

When its radio is disabled

When it is off(Note: Options B and C are duplicates. This appears to be a typo. We'll treat C as intended to be unique.)Corrected Options:

Lack of 802.11k support

When its radio is disabled

When it is not authenticated

Question # 6

During your first pre-deployment meeting with the deployment team, you hand out the full design documentation to all of them. What's your primary goal during this meeting?

Options:

To explain design decisions and ensure understanding of design documents.

To discuss AP functionality.

To explain how Wi-Fi works.

To justify the budget.

Question # 7

What are the best practices for better location accuracy when deploying Wi-Fi RTLS?

Options:

Place APs in the center of the required area and make sure that every client device is able to hear at least three APs

Place APs on the perimeter and throughout the required area and make sure that every client device is able to "hear" at least three APs

Place APs in the center of the required area and make sure that every client device is able to hear at least two APs

Place APs on the perimeter of the required area and make sure that every client device is able to "hear" at least one AP
