CWNP PW0-100 Online Questions & Answers

• Question 111:

  In an 802.11n WLAN with a heterogeneous set of associated client devices including 802.11b, 11g, and 11n, what HT protection mode will the BSS use?

  A. Mode 0: No protection mode (Greenfield)
  B. Mode 1: Nonmember protection mode
  C. Mode 2: 20 MHz protection mode
  D. Mode 3: Non-HT mixed mode
  D. Mode 3: Non-HT mixed mode

• Question 112:

  What information is transmitted in the Beacon management frames of an HT access point to communicate about backward compatibility with ERP and HR/DSSS stations? (Choose two)

  A. HT Protection mode
  B. NonERP Present field
  C. Secondary channel offset
  D. RIFS mode
  E. Power save mode of clients
  A. HT Protection mode
  B. NonERP Present field

• Question 113:

  Given:

  ABC Company performs top-secret government contract work and has recently purchased an 802.11 Wireless Intrusion Prevention System (WIPS) to enforce their "NO WIRELESS" network security policy.

  What attack type cannot be recognized by the WIPS?

  A. Deauthentication
  B. MAC Spoofing
  C. Protocol Jamming
  D. Eavesdropping
  E. RF Jamming
  D. Eavesdropping

• Question 114:

  ABC Company has a 2.4 and 5 GHz WLAN deployment supporting four bands in the 5 GHz range (UNII 1, UNII 2, UNII 2e, and UNII 3). DFS functionality is enabled as required by the regulatory domain. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.

  Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the user roams throughout the building. All APs have 2.4 and 5 GHz radios enabled. This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause of the unpredictable client band selection behavior?

  A. Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36-48 in UNII 1.
  B. 5 GHz frequencies offer better RF penetration than 2.4 GHz, but 2.4 GHz offers more voice call capacity and lower latency than 5 GHz.
  C. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.
  D. The client's band selection algorithm prefers 5 GHz, but band steering behavior usually steers 75- 85% of client devices to 2.4 GHz.
  C. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.

• Question 115:

  What answers correctly complete the following sentence? ____________ and ____________ carrier sense functions are used to determine whether the wireless medium is idle or busy. (Choose 2)

  A. Passive
  B. Pseudo-random
  C. Virtual
  D. Active
  E. Physical
  F. Interframe
  G. Vector
  C. Virtual
  E. Physical

• Question 116:

  What statement best describes the manual RF site survey report?

  A. It is a series of notes taken during the interview with the network manager and given to the site survey project manager.
  B. It is a one-page network inspection summary used to create a certificate of network compliance.
  C. It contains the results from the RF coverage, capacity, and interference analysis.
  D. It is an internal document used by the site surveying firm for network deployment, and is not usually shown to the client.
  E. It states the customer requirements, business justification, and a detailed budget for the WLAN.
  C. It contains the results from the RF coverage, capacity, and interference analysis.

• Question 117:

  Given the Wi-Fi certification shown in the exhibit, what statement is FALSE about this device?

  

  A. This client device supports protection mechanisms such as RTS/CTS and/or CTS-to-Self.
  B. This client device supports both TKIP and CCMP cipher suites.
  C. 300 Mbps is the maximum supported data rate for this device.
  D. This client device supports the ERP, OFDM, and HT physical layer specifications.
  E. This client device supports X.509 certificates for EAP authentication.
  C. 300 Mbps is the maximum supported data rate for this device.

• Question 118:

  Given: Joe runs a small hotel, and as a value added service for his customers he has implemented a Wi- Fi hot-spot. Joe has read news articles about how hackers wait at hot-spots trying to take advantage of unsuspecting users. Joe wants to avoid this problem at his hotel.

  What is an efficient and practical step that Joe can take to decrease the likelihood of active attacks on his customers' wireless computers?

  A. Implement Network Access Control (NAC) and require antivirus and firewall software along with OS patches
  B. Require EAP-FAST authentication and provide customers with a username/password on their receipt
  C. Implement an SSL VPN in the WLAN controller that initiates after HTTPS login
  D. Enable station-to-station traffic blocking by the access points in the hotel
  D. Enable station-to-station traffic blocking by the access points in the hotel

• Question 119:

  Given:

  An 802.11 WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. The cable is connected to an antenna with 16 dBi gain.

  What is the EIRP power output?

  A. 17 dBm
  B. 20 dBm
  C. 23 dBm
  D. 27 dBm
  E. 30 dBm
  E. 30 dBm

• Question 120:

  What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for 802.11 networks?

  A. WPA2-Personal uses 802.1X/EAP for authentication, and WEP-128 uses preshared keys.
  B. WPA2-Personal is based on IEEE 802.11 industry standards, but WEP is not.
  C. WPA2-Personal uses CCMP for encryption, and WEP-128 uses TKIP for encryption.
  D. WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys.
  E. WPA2-Personal requires complex 64-character hex keys, whereas WEP-128 requires weak 26- character hex keys.
  D. WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys.
