Hoofdstuk 2 Flashcards
What are two advantages of static routing over dynamic routing? (Choose two.)
Static routing is more secure because it does not advertise over the network. Static routing scales well with expanding networks. Static routing requires very little knowledge of the network for correct implementation. Static routing uses fewer router resources than dynamic routing. Static routing is relatively easy to configure for large networks.

What is the correct syntax of a floating static route?
ip route 209.165.200.228 255.255.255.248 serial 0/0/0 ip route 209.165.200.228 255.255.255.248 10.0.0.1 120 ip route 0.0.0.0 0.0.0.0 serial 0/0/0 ip route 172.16.0.0 255.248.0.0 10.0.0.1
ip route 209.165.200.228 255.255.255.248 10.0.0.1 120
What is a characteristic of a static route that matches all packets?
It backs up a route already discovered by a dynamic routing protocol. It uses a single network address to send multiple static routes to one destination address. It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route. It is configured with a higher administrative distance than the original dynamic routing protocol has.
It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.
What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
dynamic route default route destination route generic route
default route
Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?
to be used as a backup route to load-balance the traffic to act as a gateway of last resort to be the priority route in the routing table
to be used as a backup route
A company has several networks with the following IP address requirements: IP phones – 50 PCs – 70 IP cameras – 10 wireless access points – 10 network printers – 10 network scanners – 2 Which block of addresses would be the minimum to accommodate all of these devices if each type of device was on its own network?
172. 16.0.0/25 172. 16.0.0/24 172. 16.0.0/23 172. 16.0.0/22
172.16.0.0/24
What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?
The static route is removed from the routing table. The router polls neighbors for a replacement route. The static route remains in the table because it was defined as static. The router automatically redirects the static route to use another interface.
The static route is removed from the routing table.
The network administrator configures the router with the ip route 172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appear in the routing table?
C 172.16.1.0 is directly connected, Serial0/0 S 172.16.1.0 is directly connected, Serial0/0 C 172.16.1.0 [1/0] via 172.16.2.2 S 172.16.1.0 [1/0] via 172.16.2.2
S 172.16.1.0 [1/0] via 172.16.2.2
Which type of static route that is configured on a router uses only the exit interface?
recursive static route directly connected static route fully specified static route default static route
directly connected static route
What two pieces of information are needed in a fully specified static route to eliminate recursive lookups? (Choose two.)
the interface ID exit interface the interface ID of the next-hop neighbor the IP address of the next-hop neighbor the administrative distance for the destination network the IP address of the exit interface
the interface ID exit interface
the IP address of the next-hop neighbor
Consider the following command:
ip route 192.168.10.0 255.255.255.0 10.10.10.2 5
Which route would have to go down in order for this static route to appear in the routing table?
a default route a static route to the 192.168.10.0/24 network an OSPF-learned route to the 192.168.10.0/24 network an EIGRP-learned route to the 192.168.10.0/24 network
a static route to the 192.168.10.0/24 network
Refer to the exhibit. The routing table for R2 is as follows:
Gateway of last resort is not set
10.0.0.0/30 is subnetted, 2 subnets
C 10.0.0.0 is directly connected, Serial0/0/0
C 10.0.0.4 is directly connected, Serial0/0/1
192.168.10.0/26 is subnetted, 3 subnets
S 192.168.10.0 is directly connected, Serial0/0/0
C 192.168.10.64 is directly connected, FastEthernet0/0
S 192.168.10.128 [1/0] via 10.0.0.6
What will router R2 do with a packet destined for 192.168.10.129?
drop the packet send the packet out interface Serial0/0/0 send the packet out interface Serial0/0/1 send the packet out interface FastEthernet0/0
send the packet out interface Serial0/0/1
A network administrator has entered a static route to an Ethernet LAN that is connected to an adjacent router. However, the route is not shown in the routing table. Which command would the administrator use to verify that the exit interface is up?
show ip interface brief show ip protocols show ip route tracert
show ip interface brief
Consider the following command:
ip route 192.168.10.0 255.255.255.0 10.10.10.2 5
How would an administrator test this configuration?
Delete the default gateway route on the router. Ping any valid address on the 192.168.10.0/24 network. Manually shut down the router interface used as a primary route. Ping from the 192.168.10.0 network to the 10.10.10.2 addres
Manually shut down the router interface used as a primary route.
Which three IOS troubleshooting commands can help to isolate problems with a static route? (Choose three.)
show version
ping
tracert
show ip route
show ip interface brief
show arp
ping
show ip route
show ip interface brief
