CWDP-305 Practice Questions

A.  

Simply increase the output power of the APs by 30 percent to accommodate the smaller number of purchased APs

B.  

Perform a complete redesign of the wireless network and inform the customer if some original requirements cannot be accomplished

C.  

Remove as many walls as possible within the facility so that the signals can travel a greater distance

D.  

Use only 2.4 GHz radios because the signals can be received at a greater distance

A.  

Throughput rates above 50 Mbps

B.  

Data rates above 100 Mbps

C.  

Latency

D.  

PoE provided to wireless handsets

A.  

After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall on one side and your measuring device 1 meter (3.2 feet) away from the wall minus the width of the wall. Take measurements and compare the difference.

B.  

Use the pre-built attenuation values in the predictive design tools as they are more accurate than free-space metrics gathered with commercial devices.

C.  

After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall on one side and your measuring device 0.67 meters (2 feet) away from the wall on the other side. Take measurements and compare the difference.

D.  

Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material providers' websites.

A.  

PHY standard used by the AP

B.  

Key caching protocols

C.  

Cipher suite

D.  

PHY standard used by client

A.  

Patch

B.  

Dish

C.  

Grid

D.  

Low-gain dipole

A.  

Redesign the entire WLAN

B.  

Upgrade the Ethernet connections to MultiGig

C.  

Quickly add more APs

D.  

Turn up the output power on the APs so that they can handle more clients

A.  

High-speed Ethernet links

B.  

Layer 3 at the access layer

C.  

Layer 2 at the distribution layer

D.  

Routing redundancy protocol

A.  

Free space path loss causes greater signal dispersion for higher rate transmissions.

B.  

Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.

C.  

To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.

D.  

Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.

A.  

They are more susceptible to dictionary attacks than longer passphrases.

B.  

They lead to weak group keys in a BSS.

C.  

They only produce a 64-bit PMK instead of a 256-bit PMK.

D.  

Very few AP and client vendors support entry of an ASCII-based passphrase.

A.  

Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

B.  

Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

C.  

Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

D.  

Use a client device positioned where the APs will be installed and measure the signal from the client device.
