Routing that occurs when a router uses a manually configured routing
entry, rather than information from a dynamic routing traffic is
static routing dynamic routing
RIPv1 OSPF
identifies how far it is to the destination network and is based on
a metric such as the hop count, cost, bandwidth, delay, and more and
specifies the direction of the next-hop router or exit interface to reach
the destination.
Link state routing protocol
Classful routing protocol
Distance vector routing protocol

The network layer also called the Internet layer, deals with packets
and connects independent networks to transport the packets across
network boundaries. T F
A TLD (top-level domain) is the lowest level of domain names in the
root zone of the DNS of the Internet. T F
The address of IPv6 Link local is T F
The Routing Information Protocol sends routing update messages
at regular intervals and when the network topology changes.
T F
