ping
What are two advantages of static routing over dynamic routing? (Choose two.)
Static routing requires very little knowledge of the network for correct implementation.
Static routing is more secure because it does not advertise over the network.
Static routing is relatively easy to configure for large networks.
Static routing scales well with expanding networks.
Static routing uses fewer router resources than dynamic routing.
Static routing is more secure because it does not advertise over the network.
Static routing uses fewer router resources than dynamic routing.
What is the correct syntax of a floating static route?
ip route 209.165.200.228 255.255.255.248 10.0.0.1 120
ip route 209.165.200.228 255.255.255.248 serial 0/0/0
ip route 172.16.0.0 255.248.0.0 10.0.0.1
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
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 uses a single network address to send multiple static routes to one destination address.
It backs up a route already discovered by a dynamic routing protocol.
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.
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?
- 16.0.0/24
- 16.0.0/23
- 16.0.0/25
- 16.0.0/22
172.16.0.0/24
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 IP address of the exit interface
the administrative distance for the destination network
the interface ID exit interface
the IP address of the next-hop neighbor
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 router automatically redirects the static route to use another interface.
The static route remains in the table because it was defined as static.
The static route is removed from the routing table.
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 route
show ip interface brief
show ip protocols
tracert
show ip interface brief
Which type of static route that is configured on a router uses only the exit interface?
default static route
fully specified static route
recursive static route
directly connected static route
directly connected static 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 load-balance the traffic
to be used as a backup route
to act as a gateway of last resort
to be the priority route in the routing table
to be used as a backup route
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
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?
S 172.16.1.0 is directly connected, Serial0/0
S 172.16.1.0 [1/0] via 172.16.2.2
C 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
An administrator issues the ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 command on a router. What administrative distance is assigned to this route?
0
1
32
100
100
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.
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 address.
Ping any valid address on the 192.168.10.0/24 network.
Manually shut down the router interface used as a primary route.
What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
destination route
generic route
dynamic route
default route
default route
