1. Question1 pointsWhat are two advantages of static routing over dynamic routing? (Choose two.)CorrectIncorrect
HintStatic routing requires a thorough understanding of the entire network for proper implementation. It can be prone to errors and does not scale well for large networks. Static routing uses fewer router resources, because no computing is required for updating routes. Static routing can also be more secure because it does not advertise over the network.
2. Question1 pointsRefer to the exhibit. What routing solution will allow both PC A and PC B to access the Internet with the minimum amount of router CPU and network bandwidth utilization?CorrectIncorrect
HintTwo routes have to be created: a default route in R1 to reach Edge and a static route in Edge to reach R1 for the return traffic. This is a best solution once PC A and PC B belong to stub networks. Moreover, static routing consumes less bandwidth than dynamic routing.
3. Question1 pointsWhat is the correct syntax of a floating static route?CorrectIncorrect
HintFloating static routes are used as backup routes, often to routes learned from dynamic routing protocols. To be a floating static route, the configured route must have a higher administrative distance than the primary route. For example, if the primary route is learned through OSPF, then a floating static route that serves as a backup to the OSPF route must have an administrative distance greater than 110. The administrative distance on a floating static route is put at the end of the static route: ip route 184.108.40.206 255.255.255.248 10.0.0.1 120.
4. Question1 pointsWhat is a characteristic of a static route that matches all packets?CorrectIncorrect
HintA 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. Question1 pointsWhat type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?CorrectIncorrect
6. Question1 pointsWhy 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?CorrectIncorrect
HintBy 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. Question1 pointsWhich block of addresses would be the minimum to accommodate all of these devices if each type of device was on its own network?CorrectIncorrect
HintThe 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.
8. Question1 pointsWhat happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?CorrectIncorrect
HintWhen the interface associated with a static route goes down, the router will remove the route because it is no longer valid.
9. Question1 pointsThe 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?CorrectIncorrect
10. Question1 pointsRefer to the exhibit. What two commands will change the next-hop address for the 10.0.0.0/8 network from 172.16.40.2 to 192.168.1.2? (Choose two.)CorrectIncorrect
HintThe two required commands are A(config)# no ip route 10.0.0.0 255.0.0.0 172.16.40.2 and A(config)# ip route 10.0.0.0 255.0.0.0 192.168.1.2.
11. Question1 pointsWhich type of static route that is configured on a router uses only the exit interface?CorrectIncorrect
HintWhen only the exit interface is used, the route is a directly connected static route. When the next-hop IP address is used, the route is a recursive static route. When both are used, it is a fully specified static route.
12. Question1 pointsRefer to the graphic. Which command would be used on router A to configure a static route to direct traffic from LAN A that is destined for LAN C?CorrectIncorrect
HintThe destination network on LAN C is 192.168.4.0 and the next-hop address from the perspective of router A is 192.168.3.2.
13. Question1 pointsRefer 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?CorrectIncorrect
14. Question1 pointsWhat two pieces of information are needed in a fully specified static route to eliminate recursive lookups? (Choose two.)CorrectIncorrect
HintA fully specified static route can be used to avoid recursive routing table lookups by the router. A fully specified static route contains both the IP address of the next-hop router and the ID of the exit interface.
15. Question1 pointsRefer 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?CorrectIncorrect
HintTo 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.
16. Question1 pointsRefer to the exhibit. Which default static route command would allow R1 to potentially reach all unknown networks on the Internet?CorrectIncorrect
HintTo route packets to unknown IPv6 networks a router will need an IPv6 default route. The static route ipv6 route ::/0 G0/1 fe80::2 will match all networks and send packets out the specified exit interface G0/1 toward R2.
17. Question1 pointsConsider 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?CorrectIncorrect
HintThe administrative distance of 5 added to the end of the static route creates a floating static situation for a static route that goes down. Static routes have a default administrative distance of 1. This route that has an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. The administrative distance of 5 added to the end of the static route configuration creates a floating static route that will be placed in the routing table when the primary route to the same destination network goes down. By default, a static route to the 192.168.10.0/24 network has an administrative distance of 1. Therefore, the floating route with an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. Because the floating route has an administrative distance of 5, the route is preferred to an OSPF-learned route (with the administrative distance of 110) or an EIGRP-learned route (with the administrative distance of 110) to the same destination network.
18. Question1 pointsRefer 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?CorrectIncorrect
HintWhen 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.
19. Question1 pointsA 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?CorrectIncorrect
HintThe network administrator should use the show ip interface brief command to verify that the exit interface or the interface connected to the next hop address is up and up. The show ip route command has already been issued by the administrator. The show ip protocols command is used when a routing protocol is enabled. The tracert command is used from a Windows PC.
20. Question1 pointsConsider 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?CorrectIncorrect
HintA floating static is a backup route that only appears in the routing table when the interface used with the primary route is down. To test a floating static route, the route must be in the routing table. Therefore, shutting down the interface used as a primary route would allow the floating static route to appear in the routing table.
21. Question1 pointsRefer 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?CorrectIncorrect
HintR1 has a default route to the Internet. R2 has a default route to R1. R1 is missing a static route for the 10.0.60.0 network. Any traffic that reached R1 and is destined for 10.0.60.0/24 will be routed to the ISP.
22. Question1 pointsWhich three IOS troubleshooting commands can help to isolate problems with a static route? (Choose three.)CorrectIncorrect
HintThe ping, show ip route, and show ip interface brief commands provide information to help troubleshoot static routes. Show version does not provide any routing information. The tracert command is used at the Windows command prompt and is not an IOS command. The show arp command displays learned IP address to MAC address mappings contained in the Address Resolution Protocol (ARP) table.
23. Question1 pointsAn 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?CorrectIncorrect
HintThe command ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 will configure a floating static route on a router. The 100 at the end of the command specifies the administrative distance of 100 to be applied to the route.
24. Question1 pointsRefer to the exhibit. The network engineer for the company that is shown wants to use the primary ISP connection for all external connectivity. The backup ISP connection is used only if the primary ISP connection fails. Which set of commands would accomplish this goal?CorrectIncorrect
HintA static route that has no administrative distance added as part of the command has a default administrative distance of 1. The backup link should have a number higher than 1. The correct answer has an administrative distance of 10. The other quad zero route would load balance packets across both links and both links would appear in the routing table. The remaining answers are simply static routes (either a default route or a floating static default route).
25. Question1 pointsOpen 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?CorrectIncorrect
HintStatic routes should specify either a local interface or a next-hop IP address.
26. Question1 pointsOpen 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?CorrectIncorrect
HintTo reach the remote network, R1 will need a static route with a destination IPv6 address of 2001:db8:10:12::/64 and an exit interface of S0/0/1. The correct static route configuration will be as follows:ipv6 route 2001:db8:10:12::/64 S0/0/1.
