A default static route is a 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. A default static route is simply a static route with 0.0.0.0/0 as the destination IPv4 address. Configuring a default static route creates a gateway of last resort. 5. 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 6. 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 By default, dynamic routing protocols have a higher administrative distance than static routes. Configuring a static route with a higher administrative distance than that of the dynamic routing protocol will result in the dynamic route being used instead of the static route.

However, should the dynamically learned route fail, then the static route will be used as a backup. 7. 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 8. 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 The network for the PCs would require a subnet mask of /25 in order to accommodate 70 devices. That network could use IP addresses 0 through 127. Phones require a subnet mask of /26 for 50 devices (addresses 128-191). Three /28 networks are needed in order to accommodate cameras, APs, and printers. The network scanner network can use a /30. A block of addresses with a mask of /24 will accommodate this site as the minimum amount needed. 9. 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. When the interface associated with a static route goes down, the router will remove the route because it is no longer valid. 10. 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* 11.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
