Routing Flashcards
What is a router?
A piece of hardware that forwards packets based on IP address
A device that separates your computers from the Internet
A piece of hardware that distributes a single Internet connection to multiple computers
A piece of hardware that forwards packets based on IP address
A router is a piece of hardware that forwards packets based on IP address
Routers must use the same type of connection for all routes, such as Ethernet to Ethernet or ATM to ATM.
True
False
False
False; a router can interconnect different Layer 2 technologies
What technology allows you to share a single public IP address with many computers?
Static Address Translation
Natural Address Translation
Port Address Translation
Port Address Translation
Port Address Translation, commonly known as PAT, enables you to share a single public IP address with many computers
Given the following routing table:
Destination LAN IP Subnet Mask Gateway Interface
10.11.12.0 255.255.255.0 0.0.0.0 LAN
64.165.5.0 255.255.255.0 0.0.0.0 WAN
0.0.0.0 0.0.0.0 64.165.5.1 WAN
where would a packet with the address 64.165.5.34 be sent?
To the default gateway on interface WAN.
To the 10.11.12.0/24 network on interface LAN.
To the 64.165.5.0/24 network on interface WAN.
To the 64.165.5.0/24 network on interface WAN.
It would be sent to the 64.165.5.0/24 network on interface WAN
Distance vector routing protocols such as RIP rely on what metric to determine the best route?
Hop count.
Link speed.
Ping time.
Hop count.
Distance vector routing protocols use hop count to determine the best route
What are two big advantages to using OSPF over RIP? (Select two.)
OSPF is a modern protocol that does not have legacy problems.
OSPF chooses routes based on link speed, not hop count.
OSPF runs on all routers, big and small.
OSPF sends only routing table changes, reducing network traffic.
OSPF chooses routes based on link speed, not hop count.
OSPF sends only routing table changes, reducing network traffic.
OSPF bases routes on speed and sends only route changes to minimize traffic
What is Area 0 called in OSPF?
Local Area
Primary Zone
Backbone
Backbone
Area 0 is called the backbone area
What is the name of the cable that you use to connect to the console port on Cisco routers?
Router console cable
Yost cable
That funny blue Cisco cable
Yost cable
You use Yost cable, which was invented to standardize the serial console interface, to connect to the console port on Cisco routers
When you are first setting up a new router, you should never plug it into an existing network.
True
False
True
True; never plug a new router into an existing network
The traceroute utility is useful for?
Showing the physical location of the route between you and the destination
Discovering information about the routers between you and the destination address
Fixing the computer’s local routing table
Discovering information about the routers between you and the destination address
The traceroute utility is useful for discovering information about the routers between you and the destination address
