Allow unrestricted access to the console or VTY ports.
Use a firewall to restrict access from the outside to the network devices.
Always use Telnet to access the device command line because its data is automatically encrypted.
Use SSH or another encrypted and authenticated transport to access device configurations.
Prevent the loss of passwords by disabling password encryption.

This is an Ethernet port operating at half duplex.
This is an Ethernet port operating at full duplex.
This is a port on a network interface card in a PC.

It is locally significant.
It is globally significant.
It is needed to identify a unique instance of an OSPF database.
It is an optional parameter required only if multiple OSPF processes are running on the router.
All routers in the same OSPF area must have the same process ID if they are to exchange routing information.
It specifies use of a static encryption key that must be changed frequently to enhance security.
It requires use of an open authentication method.
It specifies the use of dynamic encryption keys that change each time a client establishes a connection.
It requires that all access points and wireless devices use the same encryption key.
It includes authentication by PSK.
Filtering can occur based on Layer 3 information.
Broadcasts are eliminated.
Routers generally cost less than switches.
Broadcasts are not forwarded across the router.
Adding a router to the network decreases latency.

A router is commonly considered a DTE device.
A directly connected interface with an address of 192.168.10.254/24
A static route to network 192.168.10.0/24
A RIP update for network 192.168.10.0/24
A default route with a next hop address of 192.168.10.1
A static route to network 192.168.10.0/24 with a local serial interface configured as the next hop
Broadcasts only use network layer addressing.
A broadcast frame is never forwarded by a switch.
A broadcast address will never be the source address of a frame.
Broadcast addresses use an incorrect format for the switching table.
Broadcast frames are never sent to switches.
