One advantage of dynamic routing is that it:

Correct Answer: A 🗳️
Dynamic Routing, also called adaptive routing, describes the capability of a system, through which routes are characterized by their destination, to alter the path that the route takes through the system in response to a change in conditions. The adaptation is intended to allow as many routes as possible to remain valid (that is, have destinations that can be reached) in response to the change.

Which of the following represents a Media Access Control (MAC) address?

Correct Answer: C 🗳️
The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (-) or colons
(:), in transmission order (e.g. 01-23-45-67-89-ab or 01:23:45:67:89:ab ).

Connecting to a private network address from a public network requires:

Correct Answer: A 🗳️
The majority of NATs map multiple private hosts to one publicly exposed IP address. In a typical configuration, a local network uses one of the designated
"private" IP address subnets (RFC 1918). A router on that network has a private address in that address space. The router is also connected to the Internet with a
"public" address assigned by an Internet service provider.

A network device that associates a Media Access Control (MAC) address with a port is a:

Correct Answer: D 🗳️
A switch begins learning the local MAC addresses as soon as it is connected to other devices or to a network. This learning capability makes switches easy to use on a network.
The switch learning process works like this:
1.As a PC or other networked device sends a frame to another device through the switch, the switch captures the source MAC address of the frame and the interface that received it.
2.The switch confirms or adds the MAC address and the port to the lookup table.
