  ---

  Because DHCP server maintains a database of available IP addresses and configuration information. When the server receives a request from a client, the DHCP server determines the network to which the DHCP client is connected, and then allocates an IP address or prefix that is appropriate for the client, and sends configuration information appropriate for that client

• Question 519:

  Which of the following WAN technologies has the HIGHEST latency?

  A. ADSL
  B. LTE
  C. Satellite
  D. WiMAX
  C. Satellite

  ---

  Satellite WAN latency is the delay caused by the physical distance a signal must travel from earth, to the satellite, and back to earth to complete a round-trip transmission. Because of the physics involved in the round-trip-time (RTT), end-toend latency can take 600 milliseconds or more due to geosynchronous satellites orbiting miles above the earth.

• Question 520:

  Which of the following routing protocols utilizes the DUAL algorithm for determining best path?

  A. EIGRP
  B. RIPv2
  C. OSPF
  D. RIP
  A. EIGRP

  ---
