CCNA 2 v7 Modules 14 – 16: Routing Concepts and Configuration full Exam Answers

1. Which function on a Cisco router permits the forwarding of web traffic for which over there is no specific route?

next-hopgateway of last resort*route sourceoutgoing interface

2. I m sorry three advantages are detailed by static routing? (Choose three.)

Static routing does not advertise end the network, therefore providing better security.*Configuration that static paths is error-free.Static routes scale well together the network grows.

You are watching: What is a characteristic of a default static route?

Static routing generally uses less network bandwidth and fewer CPU operations 보다 dynamic routing does.*The route a static route provides to send data is known.*No intervention is forced to maintain transforming route information.

3. What room two attributes of dynamic routing protocols? (Choose two.)

to maintain routing tables*to assure low router overheadto stop exposing network informationto find the network*to select the path that is stated by the administrator

4. What is an benefit of using dynamic routing protocols rather of revolution routing?

easier come implementmore certain in managing routing updatesfewer router resource overhead requirementsability to proactively search for new routes if the present path i do not care unavailable​*

5. What wake up to a static path entry in a routing table as soon as the outgoing interface connected with that path goes right into the under state?

The static course is removed from the routing table.*The router polls neighbors for a replacement route.The router automatically redirects the static path to use one more interface.The static route stays in the table since it was characterized as static.


Explanation: When the interface associated with a static course goes down, the router will remove the route since it is no much longer valid.


6. What is a properties of a static course that matches every packets?

It offers a single network address to send lot of static paths to one destination address.It identifies the gateway IP address to i beg your pardon the router sends all IP packets because that which that does not have a learned or revolution route.*It backs up a route already discovered by a dynamic routing protocol.It is configured with a greater administrative distance than the initial dynamic routing protocol has.


Explanation: A default static route is a course that matches all packets. It identifies the gateway IP attend to to i beg your pardon the router sends all IP packets because that which the does not have actually a learned or static route. A default static course is just a static path with 0.0.0.0/0 together the destination IPv4 address. Configuring a default static route creates a gateway of critical resort.


7. As soon as would that be more beneficial to usage a dynamic routing protocol rather of static routing?

in an company where routers endure from power issueson a stub network that has a single exit pointin an organization with a smaller network that is not meant to prosper in sizeon a network whereby there is a many topology changes*


Explanation: Dynamic routing protocols consume more router resources, are an ideal for bigger networks, and also are more useful on networks that room growing and changing.


8. Which course would be provided to forward a packet with a resource IP resolve of 192.168.10.1 and a destination IP resolve of 10.1.1.1?

C 192.168.10.0/30 is directly connected, GigabitEthernet0/1O 10.1.1.0/24 <110/65> via 192.168.200.2, 00:01:20, Serial0/1/0*S* 0.0.0.0/0 <1/0> via 172.16.1.1S 10.1.0.0/16 is directly connected, GigabitEthernet0/0


Explanation: Even despite OSPF has a higher administrative distance worth (less trustworthy), the finest match is the course in the routing table that has the most number of far left matching bits.


9. Refer to the exhibit.

*

What is the administrative distance value of the route for router R1 to reach the destination IPv6 address of 2001:DB8:CAFE:4::A?

120*11014


Explanation: The RIP course with the resource code R is offered to forward data to the destination IPv6 attend to of 2001:DB8:CAFE:4::A. This route has an advertisement value of 120.


10. Which value in a routing table to represent trustworthiness and is provided by the router to recognize which route to install right into the routing table once there are multiple routes toward the very same destination?

administrative distance*metricoutgoing interfacerouting protocol


Explanation: The governmental distance to represent the trustworthiness the a details route. The lower an administrative distance, the more trustworthy the learned course is. When a router to learn multiple routes toward the same destination, the router provides the administrative distance worth to determine which course to place into the routing table. A metric is supplied by a routing protocol to compare routes obtained from the routing protocol. An exit interface is the user interface used come send a packet in the direction that the location network. A routing protocol is provided to exchange routing updates in between two or much more adjacent routers.


12. Refer to the graphic.

*

Which command would be provided on router A come configure a static course to straight traffic indigenous LAN A the is destined because that LAN C?

A(config)# ip path 192.168.3.0 255.255.255.0 192.168.3.1A(config)# ip route 192.168.3.2 255.255.255.0 192.168.4.0A(config)# ip path 192.168.4.0 255.255.255.0 192.168.5.2A(config)# ip path 192.168.5.0 255.255.255.0 192.168.3.2A(config)# ip route 192.168.4.0 255.255.255.0 192.168.3.2*


Explanation: The location network top top LAN C is 192.168.4.0 and the next-hop attend to from the perspective of router A is 192.168.3.2.


13. On which 2 routers would a default static route be configured? (Choose two.)

any router where a back-up route to dynamic routing is essential for reliabilitythe router that serves as the gateway of last resortany router to run an IOS prior to 12.0stub router connection to the rest of the corporate or campus networkedge router connection to the ISP*


Explanation: A stub router or an leaf router connected to an ISP has only one various other router together a connection. A default static path works in those situations since all traffic will be sent to one destination. The destination router is the gateway of last resort. The default path is not configured on the gateway, however on the router sending traffic to the gateway. The router IOS does no matter.


14. Describe the exhibit.

This network has two connections to the ISP, one via router C and also one via router B. The serial link in between router A and router C supports EIGRP and is the primary connect to the Internet. If the primary link fails, the administrator needs a floating static route that stays clear of recursive route lookups and also any potential next-hop concerns caused by the multiaccess nature the the Ethernet segment through router B. What have to the administrator configure?

Create a static path pointing come 10.1.1.1 with an ad of 95.Create a totally specified static path pointing to Fa0/0 through an advertisement of 1.Create a completely specified static course pointing come Fa0/0 v an ad of 95.*Create a static course pointing come 10.1.1.1 with an ad of 1.Create a static course pointing to Fa0/0 v an ad of 1.


Explanation: A floating static path is a static path with an administrative distance higher than that of another route already in the routing table. If the course in the table disappears, the floating static course will it is in put right into the routing table in the place. Internal EIGRP has actually an ad of 90, for this reason a floating static route in this scenario would need to have an AD higher than 90. Also, when producing a static path to a multiaccess user interface like a FastEthernet segment a totally specified route have to be used, with both a next-hop IP deal with and an leave interface. This stays clear of the router from doing a recursive lookup, yet still ensures the correct next-hop an equipment on the multiaccess segment forwards the packet.


15. What is a characteristics of a floating static route?

When it is configured, it create a gateway of critical resort.​It is offered to provide load balancing between static routes.It is simply a static route with 0.0.0.0/0 as the destination IPv4 address.It is configured through a greater administrative distance 보다 the original dynamic routing protocol has.*


Explanation: Floating static paths are static routes supplied to administer a backup path come a major static or dynamic route, in the occasion of a connect failure. They should be configured v a greater administrative distance 보다 the initial dynamic routing protocol has. A default static course is simply a static route with 0.0.0.0/0 as the location IPv4 address. Configuring a default static route creates a gateway of critical resort.


16. What network prefix and prefix-length combination is used to create a default static course that will certainly match any kind of IPv6 destination?

FFFF::/128::1/64::/128::/0*


Explanation: A default static route configured for IPv6, is a network prefix of all zeros and also a prefix mask the 0 which is expressed as ::/0.


17. Take into consideration the complying with command:

ip path 192.168.10.0 255.255.255.0 10.10.10.2 5What does the 5 at the end of the command signify?

exit interfacemaximum variety of hops come the 192.168.10.0/24 networkmetricadministrative distance*


Explanation: The 5 in ~ the end of the command signifies governmental distance. This value is added to floating static routes or paths that only show up in the routing table when the wanted route has actually gone down. The 5 in ~ the finish of the command signifies administrative distance configured for the static route. This value indicates that the floating static path will appear in the routing table as soon as the preferred route (with an governmental distance much less than 5) is down.


18. Refer to the exhibit.

*

The routing table because that R2 is as follows:


Explanation: When a static route is configured v the following hop address (as in the instance of the 192.168.10.128 network), the output of the show ip route command perform the path as “via” a certain IP address. The router has to look up the IP address to determine which user interface to send the packet out. Since the IP attend to of 10.0.0.6 is component of network 10.0.0.4, the router sends out the packet out user interface Serial0/0/1.


19. An administrator issues the ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 command top top a router. What bureaucratic distance is assigned come this route?

0132100*


Explanation: The command ipv6 course 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 will configure a floating static course on a router. The 100 in ~ the finish of the command states the bureaucratic distance the 100 come be applied to the route.


20. Refer to the exhibit.

*

Which default static path command would permit R1 to potentially reach all unknown networks top top the Internet?

R1(config)# ipv6 route 2001:db8:32::/64 G0/0R1(config)# ipv6 path ::/0 G0/0 fe80::2R1(config)# ipv6 course 2001:db8:32::/64 G0/1 fe80::2R1(config)# ipv6 route ::/0 G0/1 fe80::2*


Explanation: To route packets come unknown IPv6 networks a router will require an IPv6 default route. The static route ipv6 path ::/0 G0/1 fe80::2 will enhance all networks and also send packets the end the specified departure interface G0/1 toward R2.


21. Refer to the exhibit.

The network technician for the company that is displayed wants to usage the primary ISP link for all outside connectivity. The back-up ISP connection is provided only if the primary ISP connection fails. Which set of commands would accomplish this goal?

ip path 0.0.0.0 0.0.0.0 s0/0/0ip route 0.0.0.0 0.0.0.0 s0/1/0

ip course 0.0.0.0 0.0.0.0 s0/0/0ip path 0.0.0.0 0.0.0.0 s0/1/0 10*

ip route 198.133.219.24 255.255.255.252ip path 64.100.210.80 255.255.255.252 10

ip route 198.133.219.24 255.255.255.252ip path 64.100.210.80 255.255.255.252


Explanation: A static path that has no administrative distance included as part of the command has actually a default bureaucratic distance the 1. The backup link should have a number greater than 1. The exactly answer has actually an administrative distance that 10. The other quad zero course would fill balance packets across both links and also both web links would appear in the routing table. The continuing to be answers are simply static paths (either a default path or a floating static default route).


22. Describe the exhibit.

The Branch Router has an OSPF neighbor connection with the HQ router end the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a back-up when the OSPF link goes down. The floating static path command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was issued top top Branch and now web traffic is utilizing the back-up link also when the OSPF connect is up and also functioning. Which adjust should it is in made come the static path command for this reason that web traffic will just use the OSPF connect when that is up?

Add the next hop neighbor address of 198.51.0.8.Change the bureaucratic distance come 1.Change the destination network to 198.51.0.5.Change the governmental distance to 120.*


Explanation: The trouble with the current floating static route is that the bureaucratic distance is collection too low. The bureaucratic distance will need to be higher than that of OSPF, i beg your pardon is 110, so that the router will only use the OSPF connect when it is up.


30. What characteristics completes the adhering to statement?When an IPv6 static route is configured, the next-hop deal with can it is in ……

a destination host route with a /128 prefix.the “show ipv6 course static” command.an IPv6 link-local resolve on the adjacent router.*the interface kind and interface number.

What routing systems will enable both pc A and PC B to accessibility the web with the minimum amount of router CPU and network bandwidth utilization?

Configure a dynamic routing protocol in between R1 and also Edge and advertise all routes.Configure a static course from R1 come Edge and a dynamic course from Edge come R1.Configure a revolution default course from R1 come Edge, a default route from Edge come the Internet, and a static course from Edge come R1.*Configure a dynamic route from R1 come Edge and a static route from Edge come R1.


Explanation: Two routes need to be created: a default path in R1 to with Edge and a static course in edge to with R1 because that the return traffic. This is a finest solution when PC A and also PC B belong to stub networks. Moreover, static routing consumes less bandwidth 보다 dynamic routing.


33. Describe the exhibit.

*

What would take place after the it administrator start the new static route?

The 172.16.1.0 static path would be entered into the running-config but not presented in the routing table.The 172.16.1.0 course learned from RIP would be changed with the 172.16.1.0 static route.*The 0.0.0.0 default course would be changed with the 172.16.1.0 static route.The 172.16.1.0 static route is added to the existing paths in the routing table.


Explanation: A course will be mounted in a routing table if over there is not an additional routing resource with a lower governmental distance. If a course with a lower administrative distance come the same destination network as a current route is entered, the route with the lower governmental distance will change the path with a greater administrative distance.


34. What two pieces of details are necessary in a totally specified static path to eliminate recursive lookups? (Choose two.)

the interface ID the the next-hop neighborthe user interface ID exit interface*the IP resolve of the leave interfacethe IP resolve of the next-hop neighbor*the bureaucratic distance for the destination network


Explanation: A completely specified revolution route have the right to be supplied to protect against recursive routing table lookups by the router. A fully specified static route consists of both the IP deal with of the next-hop router and the identifier of the departure interface.


35. Refer to the exhibit.

*

Which command will properly configure an IPv6 static course on R2 the will allow traffic indigenous PC2 to with PC1 without any kind of recursive lookups through router R2?

R2(config)# ipv6 path ::/0 2001:db8:32::1R2(config)# ipv6 path 2001:db8:10:12::/64 S0/0/0*R2(config)# ipv6 route 2001:db8:10:12::/64 2001:db8:32::1R2(config)# ipv6 course 2001:db8:10:12::/64 S0/0/1


Explanation: A nonrecursive course must have actually an departure interface stated from i m sorry the location network can be reached. In this instance 2001:db8:10:12::/64 is the location network and R2 will use leave interface S0/0/0 come reach that network. Therefore, the static course would be ipv6 route 2001:db8:10:12::/64 S0/0/0.


36. Describe the exhibit.

*

Which static route would an it technician go into to create a back-up route to the 172.16.1.0 network that is only offered if the major RIP learned route fails?

ip course 172.16.1.0 255.255.255.0 s0/0/0ip route 172.16.1.0 255.255.255.0 s0/0/0 121*ip course 172.16.1.0 255.255.255.0 s0/0/0 111ip course 172.16.1.0 255.255.255.0 s0/0/0 91


Explanation: A backup static route is referred to as a floating static route. A floating static route has an administrative distance better than the governmental distance of one more static path or dynamic route.


37. Open up the PT Activity. Carry out the tasks in the activity instructions and also then prize the question.

*

A user reports that PC0 can not visit the net server www.server.com. Troubleshoot the network configuration to identify the problem.What is the cause of the problem?

The clock rate on among the serial links is configured incorrectly.A serial interface on Branch is configured incorrectly.The DNS server address on PC0 is configured incorrectly.Routing between HQ and also Branch is configured incorrectly.*


Explanation: In order to enable communication to remote networks, suitable routing, either static or dynamic, is necessary. Both routers must be configured through a routing method.


38. Complement the routing table entry to the corresponding function. (Not all choices are used.)

PC A sends a request to Server B. What IPv4 resolve is used in the location field in the packet as the packet leaves computer A?

192.168.11.1192.168.10.1192.168.12.16*192.168.10.10


Explanation: The destination IP deal with in packets go not adjust along the path between the source and destination.


40. What walk R1 usage as the MAC address of the destination when building the frame that will go native R1 to Server B?

*

If the location MAC address that synchronizes to the IPv4 deal with is no in the ARP cache, R1 sends out an ARP request.*R1 provides the destination MAC address of S1.The packet is encapsulated into a PPP frame, and R1 to add the PPP destination resolve to the frame.R1 pipeline the ar blank and forwards the data to the PC.


Explanation: Communication within a neighborhood network uses deal with Resolution Protocol to acquire a MAC address from a well-known IPv4 address. A MAC attend to is necessary to build the framework in i beg your pardon the packet is encapsulated.


41. What path would have the lowest administrative distance?

a route got through the OSPF routing protocola directly linked network*a static routea route received through the EIGRP routing protocol


Explanation: The most believable path or the path with the lowest bureaucratic distance is one the is directly connected to a router.


42. A network administrator configures the user interface fa0/0 ~ above the router R1 v the command ip deal with 172.16.1.254 255.255.255.0. However, as soon as the administrator problems the command present ip route, the routing table walk not show the directly connected network. What is the possible cause of the problem?

The subnet mask is incorrect because that the IPv4 address.The interface fa0/0 has actually not been activated.*The configuration requirements to be conserved first.No packets with a location network that 172.16.1.0 have actually been sent to R1.


Explanation: A directly connected network will certainly be included to the routing table as soon as these three conditions are met: (1) the interface is configured with a valid IP address; (2) it is caused with no shutdown command; and (3) the receives a transport signal native another maker that is connected to the interface. An incorrect subnet mask because that an IPv4 resolve will not prevent its figure in the routing table, return the error may prevent successful communications.


43. A router has actually used the OSPF protocol to learn a path to the 172.16.32.0/19 network. I m sorry command will certainly implement a backup floating static path to this network?

ip course 172.16.0.0 255.255.224.0 S0/0/0 100ip path 172.16.0.0 255.255.240.0 S0/0/0 200ip route 172.16.32.0 255.255.224.0 S0/0/0 200*ip course 172.16.32.0 255.255.0.0 S0/0/0 100


Explanation: OSPF has actually an governmental distance of 110, for this reason the floating static route must have an administrative distance greater than 110. Because the target network is 172.16.32.0/19, that revolution route should use the network 172.16.32.0 and also a netmask the 255.255.224.0.


44. Take into consideration the complying with command:

ip path 192.168.10.0 255.255.255.0 10.10.10.2 5

How would certainly an administrator test this configuration?

Delete the default gateway route on the router.Manually shut down the router user interface used as a primary route.*Ping indigenous the 192.168.10.0 network come the 10.10.10.2 address.Ping any valid resolve on the 192.168.10.0/24 network.


Explanation: A floating revolution is a back-up route that only appears in the routing table as soon as the user interface used v the major route is down. To test a floating static route, the route have to be in the routing table. Therefore, shutting under the user interface used together a main route would permit the floating static course to show up in the routing table.


45. Describe the exhibit.

*

Which type of IPv6 static path is configured in the exhibit?

floating revolution routefully stated static routerecursive static route*directly attached static route


Explanation: The route provided points to another deal with that should be looked up in the routing table. This provides the course a recursive revolution route.


46. What characteristics completes the adhering to statement?When one IPv6 static route is configured, that is an initial necessary to configure ……

the next-hop resolve of 2 different surrounding routers.the “ipv6 unicast-routing” command.*an IPv6 link-local attend to on the adjacent router.an administrative distance of 2.

47. Gateway of last will is no set.

Refer to the exhibit. Which interface will it is in the leave interface to front a data packet that has the location IP deal with 172.18.109.152?

GigabitEthernet0/0GigabitEthernet0/1Serial0/0/0*None, the packet will certainly be dropped.

48. Open up the PT Activity. Do the work in the task instructions and also then answer the question.A user reports the PC0 cannot visit the net server www.server.com. Troubleshoot the network configuration to identify the problem.What is the cause of the problem?

The clock rate on among the serial links is configured incorrectly.A serial interface on Branch is configured incorrectly.The DNS server resolve on PC0 is configured incorrectly.Routing between HQ and Branch is configured incorrectly.*


Explanation: In order to permit communication to remote networks, ideal routing, either revolution or dynamic, is necessary. Both routers have to be configured v a routing method.


49. Consider the adhering to command:

ip course 192.168.10.0 255.255.255.0 10.10.10.2 5

Which route would have to go down in order because that this static path to appear in the routing table?

a default routea static path to the 192.168.10.0/24 network*an OSPF-learned course to the 192.168.10.0/24 networkan EIGRP-learned route to the 192.168.10.0/24 network


Explanation: The bureaucratic distance of 5 included to the end of the static path creates a floating static case for a static route that walk down. Static routes have actually a default governmental distance that 1. This route that has actually an governmental distance of 5 will certainly not be put into the routing table uneven the previously gotten in static route to the 192.168.10.0/24 goes down or was never entered. The governmental distance of 5 included to the end of the static path configuration create a floating static course that will certainly be inserted in the routing table once the main route to the same location network go down. By default, a static route to the 192.168.10.0/24 network has an bureaucratic distance of 1. Therefore, the floating course with an governmental distance that 5 will certainly not be placed into the routing table uneven the previously entered static path to the 192.168.10.0/24 goes down or was never entered. Due to the fact that the floating route has actually an bureaucratic distance that 5, the route is preferred to an OSPF-learned path (with the administrative distance of 110) or one EIGRP-learned path (with the administrative distance that 110) to the same location network.


50. What are two advantages of static routing end dynamic routing? (Choose two.)

Static routing is an ext secure since it does no advertise over the network.*Static routing scales fine with expanding networks.Static routing requires very tiny knowledge of the network because that correct implementation.Static routing provides fewer router sources than dynamic routing.*Static routing is reasonably easy to configure for big networks.


Explanation: Static routing calls for a thorough understanding of the whole network for suitable implementation. It have the right to be susceptible to errors and does not scale well for large networks. Static routing supplies fewer router resources, since no computing is forced for updating routes. Revolution routing can also be an ext secure due to the fact that it does not advertise over the network.


51. What characteristics completes the complying with statement?When an IPv6 static path is configured, that is possible that the exact same IPv6 link-local address is offered for …

a destination host course with a /128 prefix.the “ipv6 unicast-routing” command.
