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.

C. Wait five minutes until the PC resends a DHCP request
D. Run netstat on each PC and then reboot into safe mode

B. Establish procedures which limit user connections during peak hours.
C. Configure the access points so that they all use different SSIDs.
D. Move one or more access points, minimizing signal overlap.
After deploying a network switch, the network administrator is unable to remotely administer the device. The network administrator notices that the switch has the following configuration.
Which of the following is the MOST likely cause of this issue? Management LAN: 192.168.10.0/24 Management interfacE. 192.168.10.2 255.255.255.0 Default gateway: 192.168.11.1 STP is enabled

B. Increase the pool in each of the access points to avoid running out of IPs.
C. Configure each access point to use a different method of encryption than the others.
D. Reconfigure each of the access points so that they broadcast different SSIDs.
A new WAP is configured to only use 802.11g with SSID broadcasts enabled. The encryption is set to WPA and the key is given to the user. A user near the WAP is using a laptop equipped with a 5GHz wireless card and is not able to see the SSID.
Which of the following is the problem?
A. Latency
B. Incorrect encryption type
C. EUI-64
D. Incompatible hardware
Which of the following DHCP options is used to exclude IP addresses from being distributed to other computers?
