Answer: C,E


NEW QUESTION # 128

  • A. Non-HT Duplicate
  • B. Dual-CTS
  • C. HT-mixed format
  • D. HT-greenfield format
  • E. Phased Coexistence PPDU

Answer: A


NEW QUESTION # 129

The vendor specifications sheet does not provide detailed information.
What tool can you use to provide the most detailed specification information in many such cases?

  • A. Wi-Fi finder
  • B. Spectrum analyzer
  • C. FCC ID Search
  • D. WLAN controller

Answer: C


NEW QUESTION # 130
In which element of a Beacon frame would you look to identify the current HT protection mode in which an AP is operating?

  • A. HT Capabilities Element
  • B. HT Information Element
  • C. HT Operations Element
  • D. HT Protection Element

Answer: B

Explanation:
The HT Information Element in a Beacon frame contains information about the current HT (High Throughput) protection mode in which an access point (AP) is operating. This element is used to ensure backward compatibility between HT (802.11n) and non-HT stations.


NEW QUESTION # 131
Which one of the following is an advantage of using display filters that is not an advantage of capture-time filters?

  • A. Multiple of them can be applied simultaneously
  • B. They only hide the packets from view and the filtered packets can be enabled for view later
  • C. Once created they are reusable for later captures
  • D. They allow for focused analysis on just the packets of interest

Answer: B

Explanation:
Explanation
Display filters are applied after the capture is completed and they only hide the packets from view. The filtered packets are still present in the capture file and can be enabled for view later by changing or removing the display filter. This is an advantage over capture-time filters, which discard the packets that do not match the filter criteria and cannot be recovered later34 References:
