gateway of last resort

feature on a Cisco router permits the forwarding of traffic for which there is no specific route

what network prefix and pre-fix combination is used to create a default static route that will match any IPv6 destination

::/0

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

advantage of using dynamic routing protocols instead of static routing

ability to actively search for new routes if current path becomes unavailable

Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 What does the 5 at the end of the command signify?

administrative distance

Which value in a routing table represents trustworthiness and is used by the router to determine which route to install into the routing table when there are multiple routes toward the same destination

administrative distance

characteristic of static route that matches all packets

it ids the gateway IP add to which the router sends all IP packets for which it doesn't have a learned or static route

what is a characteristic of a floating static route

its configured w a higher administrative distance than the original dynamic routing protocol has

when would it be more beneficial to use dynamic routing protocol instead of static?

on a network where there is a lot of topology changes

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. A user reports that PC0 cannot visit the web server www.server.com. Troubleshoot the network configuration to identify the problem. What is the cause of the problem?

routing between HQ and Branch is configured incorrectly

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 subnetsC 10.0.0.0 is directly connected, Serial0/0/0C 10.0.0.4 is directly connected, Serial0/0/1192.168.10.0/26 is subnetted, 3 subnetsS 192.168.10.0 is directly connected, Serial0/0/0C 192.168.10.64 is directly connected, FastEthernet0/0S 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

Refer to the exhibit. An administrator is attempting to install an IPv6 static route on router R1 to reach the network attached to router R2. After the static route command is entered, connectivity to the network is still failing. What error has been made in the static route configuration?

the interface is incorrect

Refer to the exhibit. An administrator is attempting to install a default static route on router R1 to reach the Site B network on router R2. After entering the static route command, the route is still not showing up in the routing table of router R1. What is preventing the route from installing in the routing table?

the next hop add is incorrect

Refer to the exhibit. How was the host route 2001:DB8:CAFE:4::1/128 installed in the routing table?

the route was manually entered by an admin

Refer to the exhibit. A ping from R1 to 10.1.1.2 is successful, but a ping from R1 to any address in the 192.168.2.0 network fails. What is the cause of this problem?

the static route for 192.168.2.0 is incorrectly configured

what happens to a static route entry in a routing table when the outgoing interface with that route goes into the down state

the static route is removed from the routing table

Which three advantages are provided by static routing

*Static routing does not advertise over the network, thus providing better security *Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does *The path a static route uses to send data is known.

What two pieces of information are needed in a fully specified static route to eliminate recursive lookups? (Choose two.)

*interface ID exit interface *ip add of next-hop neighbor

2 functions of dynamic routing protocols

*maintain routing tables *discover the network

Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process? (Choose two.)

*packet with the destination IP address of ServerB. *frame with the destination MAC address of Router A.

on which 2 routers would a default static route be configured

*stub router connection to the test of the corporate or campus network *edge router connection to the ISP

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?

100

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 route would be used to forward a packet with a source IP 192.168.10.1 and a destination IP 10.1.1.1

O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, s0/1/0

Refer to the exhibit. Which set of commands will configure static routes that will allow the Park and the Alta routers to a) forward packets to each LAN and b) direct all other traffic to the Internet?

Park(config)# ip route 0.0.0.0 0.0.0.0 192.168.14.1Alta(config)# ip route 10.0.234.0 255.255.255.0 192.168.14.2Alta(config)# ip route 0.0.0.0 0.0.0.0 s0/0/0

Refer 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?

ip route 0.0.0.0 0.0.0.0 s0/0/0 ip route 0.0.0.0 0.0.0.0 s0/1/0 10
