Routers
Routers are used for what purpose?
Routers are used to interconnect remote sites.
What happens to a packet if there is no matching route entry?
The packet is dropped.
What are Remote Routes?
Remote networks connected to other routers.
Wireless is what type of duplex?
half-duplex
Switches use what to direct network communications through the switch?
MAC addresses
What level do OSI layer do routers run on?
Network layer (Layer 3)
To encapsulate a packet in the Ethernet frame, what does a router need
What are static routes?
A Static route is when a route is manually configured and the exit interface is active.
What is the physical layer difference between wireless and wired ethernet LANs?
Wireless uses radio frequency (RF), while wired uses physical cables.
How many paths does STP ensure there are?
STP ensures that there is only one possible path.
What two primary functions do Routers have.
Path determination and packet forwarding.
How does a router Forward a packet to a known device?
The Router examines the IP address in the packet header and consults its IP routing table.
What are directly connected routes?
Directly connected routes are from active router Interfaces.
What media access control does wireless use?
collision avoidance
What does STP prevent?
STP prevents loops.
The routing process uses what to determine the most efficient path for forwarding an IP packet?
Network routing tables, protocols, and algorithms
(One of any of the three answers counts as being correct)
What does a Router use when it's looking for a matching IPv4 address?
The router sends out an ARP request
What is Dynamic routing protocol?
This is when routing protocols dynamically learn about the network.
What do WLANS use to determine how and when to send data on the network?
CSMA/CA
What is a routed port?
It is a pure Layer 3 interface similar to a physical interface on a Cisco IOS router.
What is the primary responsibility of the switching function on a router?
I's primary function is to encapsulate packets in the appropriate data link frame type for the outgoing data link.
What does a Router use when it's looking for a matching IPv6 address
The router sends out an ICMPv6 Neighbor Solicitation (NS) message
what year was the first routing protocol RIPv1 released in?
1988
For wireless devices to communicate over a network they must complete a three step process. What is this process?
What is W-ARP?
We're no strangers to love
You know the rules and so do I
A full commitment's what I'm thinking of
You wouldn't get this from any other guy
I just wanna tell you how I'm feeling
Gotta make you understand
Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
Never gonna make you cry
Never gonna say goodbye
Never gonna tell a lie and hurt you
