02
Front
When several routes match, which one does a router use?
Back
The router selects the most specific matching route—the one with the longest prefix.
03
Front
What distinguishes a static route?
Back
A static route is entered manually and stays configured until it is changed or removed; it does not automatically adapt to topology changes.
04
Front
When are static routes useful?
Back
Static routes are useful in small or stable networks, for specific paths, or as backup routes.
05
Front
What is the general Cisco IOS command for configuring a static route?
Back
Use: ip route destination-network subnet-mask next-hop-address
06
Front
What static route lets R1 reach the LAN at 192.168.2.0/24?
Back
R1(config)# ip route 192.168.2.0 255.255.255.0 10.0.12.2
07
Front
What must be true of a static route’s next hop?
Back
The next hop must be reachable through an active interface.
08
Front
Why is a route on only one router insufficient for two-way communication?
Back
The destination network needs a route back to the source; a route on only one router is not enough for two-way communication.
09
Front
How do you remove a static route in Cisco IOS?
Back
Negate the route command with no, for example: no ip route 192.168.2.0 255.255.255.0 10.0.12.2
10
Front
When does a router use a default route?
Back
A default route is used when no more-specific route matches the destination. It is also called the gateway of last resort.
11
Front
What is the Cisco IOS command form for an IPv4 default route?
Back
On Cisco IOS, configure it with: ip route 0.0.0.0 0.0.0.0 next-hop-address
12
Front
Does a default route replace routes to internal networks?
Back
No. A default route handles otherwise-unmatched destinations; it does not replace routes needed to reach internal networks.
