/24

What is a valid summary route for IPv6 networks 2001:0DB8:ACAD:4::/64, and 2001:0DB8:ACAD:7::/64?

/62

What would be the best summary route for the following networks? 10.50.168.0/23 10.50.170.0/23 10.50.172.0/23 10.50.174.0/24

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

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?

S 172.16.1.0 [1/0] via 172.16.2.2

Refer to the exhibit. R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 foward the packet?

Serial0/0/1

What are two advantages of static routing over dynamic routing?

Static routing is more secure because it does not advertise over the network. Static routing uses fewer router resources than dynamic.

What would be the first step in calculating a summarized route for 5 networks?

Write all network numbers in binary.

What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?

default route

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 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 s0/0/0 ip route 0.0.0.0.0.0.0 s0/1/0 10

What is the correct syntax of a floating route?

ip route 209.165.200.228 255.255.255.248 10.0.0.1 120

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What IPv6 static route can be configured on R1 to make a fully converged network?

ipv6 route 2001:db8:10:12::/64 S0/0/1

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

Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 How would the administrator test this configuration?

manually shutdown the router interface used as a primary route

Which three IOS troubleshooting commands can help to isolate problems with a static route?

ping show ip route show ip interface brief

Refer to the exhibit. 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?

A(config)# ip route 192.168.4.0 255.255.255.0 192.168.3.2

Refer 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?

Configure a static default route from R1 to Edge, a default route from Edge to the Internet, and a static route from Edge to R1.

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

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

Which two statements describe classful IP addresses?

The number of bits used to identify the hosts is fixed by the class of the network. All subnets in a network are the same size

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.

What two pieces of information are needed in a fully specified route to eliminate recursive lookups?

the interface ID exit interface the IP address of the next-hop neighbor

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

What does VLSM allow a network administrator to do?

utilize multiple different subnet masks in the same IP address space
