You are troubleshooting a network issue on a client computer and discover that the network card has an IP address of 169.254.196.200. What does this mean?
The computer is configured to use DHCP, but was unable to lease an address.
How can you determine the manufacturer of a NIC card based on the MAC address?
The first 24 bits, known as the Organizationally Unique Identifier, identify the manufacturer.

True
Each type of cable has a prescribed bend radius, which is the radius of the maximum arc into which you can loop a cable without impairing data transmission.
True
In general, an API (application programming interface) call is the method an application uses when it makes a request of the OS.
True
The process of designing, implementing, and maintaining an entire network is called the system life cycle.
True
