• Question 174:

  Which Python code snippet must be added to the script to save the returned configuration as a JSON-formatted file?

  

  A. with open("ifaces.json", "w") as OutFile:OutFile.write(Response.text)
  B. with open("ifaces.json", "w") as OutFile:OutFile.write(Response.json())

  D. with open("ifaces.json", "w") as OutFile:OutFile.write(Response)
  B. with open("ifaces.json", "w") as OutFile:OutFile.write(Response.json())

  ---

  Explanation

  The json() method of the Response interface takes a Response stream and reads it to completion. It returns a promise which resolves with the result of parsing the body text as JSON.

• Question 175:

  C. antenna gain
  D. RSSI
  E. transmit power
  B. noise floor
  D. RSSI

  ---

  Explanation

  signal-to-noise ratio (SNR) A measure of received signal quality, calculated as the difference between the signal's RSSI and the noise floor. A higher SNR is preferred.

• Question 180:

  Refer to the exhibit.

  

  An engineer is investigating why guest users are able to access other guest user devices when the users are connected to the customer guest WLAN. What action resolves this issue?

  A. implement MFP client protection
  B. implement split tunneling
  C. implement P2P blocking
  D. implement Wi-Fi direct policy

  Explanation

  2.3 Ensure `Peer-to-Peer Blocking Action` is set to `Drop' for All `Wireless LAN Identifiers' (Scored)

  Description:

  This control determines whether the Wireless LAN Controller is configured to prevent clients connected to the same Wireless Local Area Controller from communicating with each other. Wireless Client Isolation prevents wireless clients from communicating with each other over the RF. Packets that arrive on the wireless interface are forwarded only out the wired interface of an Access Point. One wireless client could potentially compromise another client sharing the same wireless network.
