CWNP PW0-104 Online Questions & Answers

• Question 121:

  Given: As defined in the 802.11 specification, legacy Power Save requires an inefficient back-and-forth frame exchange process. Due to this inefficiency, many WLAN device implementations use a variation of 802.11 Power Save to accomplish the same function.

  What non-standard power save behavior is used by most Wi-Fi devices in actual implementations?

  A. Client devices ignore the TIM field and automatically send PS-Poll frames after every beacon.
  B. After each beacon, the AP attempts to empty its frame buffer by sending Wake-on-WLAN frames to wake each dozing client.
  C. Request-to-Send and Clear-to-Send frame exchanges are used to trigger the delivery of buffered data.
  D. The Beacon interval is changed from the default 100 time units to 10 or less time units.
  E. Clients send null data frames to the AP and switch the power management bit from 1 to 0 to receive queued data.
  F. Stations send a CTS-to-self frame to the AP with a very long duration period so they can receive all of their buffered data at once.
  E. Clients send null data frames to the AP and switch the power management bit from 1 to 0 to receive queued data.

• Question 122:

  Which unit of measurement is a relative unit that is used to quantify power level changes?

  A. dBm
  B. dBW
  C. dB
  D. mW
  E. VSWR
  C. dB

• Question 123:

  Which data rate is supported by 802.11g radios that is not supported by 802.11a radios?

  A. 9 Mbps
  B. 11 Mbps
  C. 12 Mbps
  D. 54 Mbps
  E. 65 Mbps
  F. 130 Mbps
  B. 11 Mbps

• Question 124:

  What statements about the SSID are true? (Choose two)

  A. The SSID is a security session identifier used in RSNs.
  B. The SSID must be included in an association request frame.
  C. The SSID is an alphanumeric value assigned to device manufacturers by the IEEE.
  D. The SSID is a pseudo-random number assigned to each client by an AP.
  E. The SSID is an alphanumeric value with a maximum length of 32 octets.
  F. When configuring a new network, creating an SSID is optional.
  B. The SSID must be included in an association request frame.
  E. The SSID is an alphanumeric value with a maximum length of 32 octets.

• Question 125:

  What statements accurately describe the RF cables and connectors that are used in an 802.11 WLAN system? (Choose three)

  A. RF cables have upper and lower frequency range specifications.
  B. 75 and 125 ohms are the typical impedances of 802.11 WLAN connectors.
  C. Two RF connectors of the same type (e.g. SMA), manufactured by different companies, may vary in specifications.
  D. Every RF connector causes insertion loss.
  E. Large diameter RF cables cause greater loss than small diameter cables.
  F. Coaxial RF cables can be used to carry Power-over-Ethernet (PoE) to an outdoor bridge mounted on a mast.
  A. RF cables have upper and lower frequency range specifications.
  C. Two RF connectors of the same type (e.g. SMA), manufactured by different companies, may vary in specifications.
  D. Every RF connector causes insertion loss.
