Question 1

What is the recommended signal threshold for designing a wireless network that supports

voice over Wi-Fi (VoWi-Fi)?

A--72 dBm

B--67 dBm

C--80 dBm

D--50 dBm

Answer : B

Question 2

A university lecture hall has high client density. Which antenna type is most appropriate to

reduce co-channel interference and improve coverage?

AHigh-gain directional antennas

BOmni-directional antennas

CPatch or panel directional antennas

DYagi antennas

Answer : C

Question 3

An engineer is designing a wireless deployment for a university auditorium. Which two features can be used to help deal with the issues introduced by high AP count? (Choose two.)

ATSPEC

BRXSOP

CTPC

DLSS

EDFS

Answer : B, C

RXSOP (Receive Start of Packet Detection Threshold) and TPC (Transmit Power Control) are two features that can help manage the challenges associated with a high AP (Access Point) count in a dense environment like a university auditorium. RXSOP can be adjusted to refine how APs differentiate between noise and valid packets, which is particularly useful in high-density areas where multiple APs might otherwise respond to the same signal. TPC helps in managing the transmit power of APs, allowing for better coverage and reduced interference among APs that are in close proximity to each other.Reference: Designing Cisco Enterprise Wireless Networks (ENWLSD 300-425)

Question 4

Which design consideration is most important for real-time applications such as voice and video over WLAN?

AHigh data rates

BLow latency and jitter

CMaximum throughput

DUse of DFS channels

Answer : B

Question 5

Which survey type uses predictive modeling software instead of physically visiting the site?

APassive survey

BPredictive survey

CActive survey

DPost-deployment survey

Answer : B

Question 6

Which IEEE standard enables Fast BSS Transition (FT) for seamless roaming?

A802.11k

B802.11r

C802.11v

D802.11ac

Answer : B

Question 7

What is the wireless signal loss of large cases of liquid materials being stored in a warehouse environment?

AIt is higher than dry goods.

BIt is not impactful to the RF design.

CIt is less than dry goods.

DIt is impactful but overall negligible to the RF design.

Answer : A

Large cases of liquid materials can cause higher signal loss compared to dry goods due to the way radio frequency (RF) waves interact with liquid, which can absorb and reflect the signals more than dry materials.
