Switches
What is a layer 3 switch commonly referred to?
Managed switch
What is a router used for?
Transferring Data
Are switches NEEDED in a network for connection?
No; a router is only needed.
This determines which bits are network bits, and require all preceding bits to be 1.
Subnet Mask
A collection of devices which communicate with each other
Network
The main cable used to connect ports on a switch
RJ-45
Where is a routing table stored within a router? (HINT: 3-letter acronym)
RAM (Random Access Memory)
How can a person alter which ports are blocked on your computer?
Port Forwarding
Can a dynamic route be changed manually?
No; it automatically changes, based on metrics.
What is it known as when smaller networks are combined into one?
Network Convergence
A switch port shows a yellow LED light when a cable is connected to it. What does this most likely indicate?
A port is operating at less than full speeds
The name of a route with one total hop.
Directly Connected Route
What do routing tables prioritize in determining metrics?
Matching Prefixes
In a route entry, what purpose does the 'next hop' hold?
It determines where a packet goes from the current entry.
An isolated grouping of devices from a larger group of devices
Subnet
What is the main difference between a layer 2 and layer 3 switch?
Configuration capabilities
This route can only be changed manually
Static Route
Two devices are connected. One is using Fast Ethernet and the other Gigabit Ethernet. What will be the speed of the connection?
Fast Ethernet (100 Mbps)
What is the purpose of metric settings within a route?
It indicates the cost (or number of routes) which must be crossed to reach a specified destination.
How can network bottlenecks be prevented?
Quality of Service (QoS), and/or Port Forwarding
What is an alternative name for a managed switch?
Layer 3 Switch
This protocol uses hop count as its primary metric
RIP (Routing Information Protocol)
This points towards the default gateway; it matches all packets.
Default Route
What command would be used to create a route with 192.168.2.0 network, using a subnet mask of 255.255.255.0 and a next hop of 192.168.2.1.
ip route 192.168.2.0 255.255.255.0 192.168.0.1
How could you prevent a full network from failing in case of technology failing?
Backup Recovery
