Why should your company use a high-availability DHCP solution?  Better what?  Any drawbacks?  What's different?  How quickly would your network detect a DHCP failure?  Your home's DHCP failure detection time?

In an ongoing investigation of a crime, you have been granted a warrant to tap the office communications of a suspect. What type of equipment would you deploy to intercept network traffic? Where would you put the network sensors? Explain how/why your surveillance would go unnoticed to the suspected criminal. Is there anything you could have done better to engage in surveillance?

Your company has built a network, but in one of the buildings, some of the devices have stopped working. None of the devices are even turned on. To satisfy your employer, you've agreed to investigate the likely causes of the malfunctioning machinery. Provide suggestions for measures that may be taken to increase the safety of other devices. Please detail two potential approaches to this.

What can be done to lessen the chance of a network failure?
