• Question 1628:

  A technician has spent most of the day replacing a server running DHCP. Some of the users have begun to call the help desk stating that Internet connection stopped working even after rebooting. Upon investigation, the users' PCs with issues all have IP addresses that start with 169.254.x.x. The technician completes the replacement and powers on the new DHCP server. Which of the following is the BEST way to provide the PCs with issues a new IP address?

  A. Statically assign a legitimate IP address, and then set the PCs' NICs to DHCP
  B. Inform each user to replace 169.254 with 192.168
  C. Wait five minutes until the PC resends a DHCP request
  D. Run netstat on each PC and then reboot into safe mode
  C. Wait five minutes until the PC resends a DHCP request

• Question 1629:

  Which of the following devices implements CSMA/CA virtually through the RTS/CTS protocols?

  A. Firewall
  B. Router
  C. 802.11 AP
  D. Switch
  C. 802.11 AP

  802.11 AP is a Wireless Access Point used in a wireless network. If two computers on a network send data frames at thesame time, a collision between the frames can occur. The frames are then discarded and the sending computers will attempt to send the data again. Carrier sense multiple access with collision avoidance (CSMA/CA) is a protocol used in wireless networks wherecomputers connected to the wireless network attempt to avoid collisions by transmitting data only when the channel is sensed to be "idle". Carrier Sense Multiple Access/Collision Detect (CSMA/CD) is unreliable in wireless networks because computers connected to the wireless network often cannot see each other so CSMA/CA is a better option for avoiding collisions. Request to Send/Clear to Send (RTS/CTS) can also be used to mediate access to the wireless network. This goes some way to alleviating the problemof computers not being able to see each other because in a wireless network, the Wireless Access Point only issues a "Clear to Send" to one node at a time. With RTS/CTS, a Request to Send (RTS) packet is sent by the sending computer, and a Clear to Send(CTS) packet is sent by the intended receiver. This will alert all computers within range of the sender, receiver or both, to not transmit for the duration of the transmission. This is known as the IEEE 802.11 RTS/CTS exchange.

  A. Throughput
  B. Latency
  C. Goodput
  D. Bandwidth
  A. Throughput
