CWNP Wireless Network Administrator (CWNA) Sample Questions (Q27-Q32):NEW QUESTION # 27
You are implementing a VHT-capable AP. Which one of the following channels is available in the 802.11-
2016 standard that was not available before the ratification of 802.11 ac?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: B
Explanation:
Channel 144 is a new channel that was added to the 5 GHz band by the 802.11ac amendment, which defines the VHT (Very High Throughput) PHY for WLANs. Channel 144 has a center frequency of 5720 MHz and a bandwidth of 20 MHz. It can also be combined with adjacent channels to form wider channels of 40 MHz, 80 MHz, or 160 MHz. Channel 144 is available in some regions, such as North America and Europe, but not in others, such as Japan and China .

NEW QUESTION # 28
What ID is typically mapped to an AP's MAC address if a single BSS is implemented?
  • A. SSID
  • B. Device ID
  • C. VLAN ID
  • D. BSSID
Answer: D
Explanation:
The BSSID (Basic Service Set Identifier) is typically mapped to an AP's MAC address if a single BSS is implemented. The BSSID is a unique identifier that distinguishes one BSS from another within the same RF medium. It is usually derived from the MAC address of the AP's radio interface, but it can also be manually configured or randomly generated by some vendors. The BSSID is used by client stations to associate with an AP and to send and receive frames within a BSS. References: , Chapter 1, page 24; , Section 1.2

NEW QUESTION # 29
Which one of the following channels can be used for VHT transmissions according to the 802.11 specification?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: B
Explanation:
The channel that can be used for VHT transmissions according to the 802.11 specification is channel 144.
VHT stands for Very High Throughput and is the PHY layer specification for 802.11ac devices. VHT transmissions can use channel bandwidths of 20 MHz, 40 MHz, 80 MHz, or 160 MHz in the 5 GHz band.
Channel 144 is one of the channels in the 5 GHz band that can support VHT transmissions with any of these bandwidths. Channel 6, channel 1, and channel 11 are channels in the 2.4 GHz band that cannot support VHT transmissions, as they are only compatible with legacy (802.11b/g/n), HT (802.11n), or ERP (802.11g) transmissions with up to 20 MHz bandwidth. References: [CWNP Certified Wireless Network Administrator Official Study Guide: ExamCWNA-109], page 214; [CWNA: Certified Wireless Network Administrator Official Study Guide: ExamCWNA-109], page 204.

NEW QUESTION # 30
When a STA has authenticated to an AP (AP-1), but still maintains a connection with another AP (AP-2), what is the state of the STA on AP-1?
  • A. Transitional
  • B. Unauthenticated and Unassociated
  • C. Authenticated and Associated
  • D. Authenticated and Unassociated
Answer: D
Explanation:
Authenticated and Unassociated. According to one of the web search results1, a STA can be authenticated to multiple APs, but it can only be associated to one AP at a time. Association is the process of establishing a logical link between the STA and the AP, which allows the STA to send and receive data frames through the AP2. Therefore, when a STA has authenticated to an AP-1, but still maintains a connection with another AP-2, it means that the STA is authenticated to both APs, but only associated to AP-2. The state of the STA on AP-1 is authenticated and unassociated, which means that the STA can switch to AP-1 without repeating the authentication process, but it cannot send or receive data frames through AP-1 until it becomes associated.

NEW QUESTION # 31
An 802.11 WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB of loss. The cable is connected to an antenna with 16 dBi of gain. What is the power level at the Intentional Radiator?
  • A. 500 mW
  • B. 1000 mW
  • C. 250 mW
  • D. 25 mW
Answer: B
