What is a characteristic of a static route that matches all packets?
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.
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
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?
Needs at least a /25 subnet to accommodate 70 devices.
Which type of static route that is configured on a router uses only the exit interface?
Directly Connected Static Route
Refer to the exhibit. The network administrator needs to configure a default route on the Border router. Which command would the administrator use to configure a default route that will require the least amount of router processing when forwarding packets?
Border(config)# ip route 0.0.0.0 0.0.0.0 s0/0/1
What two pieces of information are needed in a fully specified static route to eliminate recursive lookups? (Choose two.)
IP Address of the next hop router
ID of the exit interface.
Refer to the exhibit. What command would be used to configure a static route on R1 so that traffic from both LANs can reach the 2001:db8:1:4::/64 remote network?
ipv6 route 2001:db8:1:4::/64 2001:db8:1:3::2
Explanation: To configure an IPv6 static route, use the ipv6 route command followed by the destination network. Then add either the IP address of the adjacent router or the interface R1 will use to transmit a packet to the 2001:db8:1:4::/64 network.
Refer to the exhibit. Which default static route command would allow R1 to potentially reach all unknown networks on the Internet?
R1(config)# ipv6 route ::/0 G0/1 fe80::2
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 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?
send the packet out interface Serial0/0/1
Explanation: When a static route is configured with the next hop address (as in the case of the 192.168.10.128 network), the output of the show ip route command lists the route as "via" a particular IP address. The router has to look up that IP address to determine which interface to send the packet out. Because the IP address of 10.0.0.6 is part of network 10.0.0.4, the router sends 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
Refer to the exhibit. The small company shown uses static routing. Users on the R2 LAN have reported a problem with connectivity. What is the issue?
R1 needs a static route to the R2 LAN.
Which three IOS troubleshooting commands can help to isolate problems with a static route? (Choose three.)
ping, show ip route, and show ip interface brief.
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What IPv6 static route can be configured on router R1 to make a fully converged network?
ipv6 route 2001:db8:10:12::/64 S0/0/1.
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Why are the pings from PC0 to Server0 not successful?
The static route to network 192.168.2.0 is misconfigured on Router1.
