• Question 632:

  Which two pieces of information are necessary to compute SNR? (Choose two.)

  A. EIRP

  B. noise floor

  C. antenna gain

  D. RSSI

  E. transmit power

  Correct Answer: BD

  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. Reference: https://community.cisco.com/t5/wireless-mobility-documents/snr-rssi-eirp-and-free-space-path-loss/ta-p/3128478

• Question 640:

  An engineer uses the Design workflow to create a new network infrastructure in Cisco DNA Center. How is the physical network device hierarchy structured?

  A. by location

  B. by role

  C. by organization

  D. by hostname naming convention

  Correct Answer: A

  This is because the Design workflow in Cisco DNA Center allows the engineer to create a new network infrastructure by defining the physical network device hierarchy based on the location of the devices. The location hierarchy consists of four levels: global, area, building, and floor. The engineer can add, edit, or delete locations and assign devices to them. The location hierarchy helps to organize the network devices and apply policies and settings based on the location.
