What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
Open the PT activity. Perform the tasks in the activity instructions and then answer the question. What is the name of the web server that is displayed in the webpage?
What is a valid summary route for IPv6 networks 2001:0DB8:ACAD:4::/64, 2001:0DB8:ACAD:5::/64, 2001:0DB8:ACAD:6::/64, and 2001:0DB8:ACAD:7::/64?
What would be the best summary route for the following networks?
What happens to a static route entry in a routing table when the outgoing interface is not available?
The route is removed from the table.*
The route remains in the table because it was defined as static.
The router polls neighbors for a replacement route.
The router redirects the static route to compensate for the loss of the next hop device.
Which type of static route that is configured on a router uses only the exit interface?
recursive static route
default static route
directly connected static route*
fully specified static route
What does VLSM allow a network administrator to do?
utilize one dynamic routing protocol throughout the entire network
utilize one subnet mask throughout a hierarchical network
utilize multiple different subnet masks in the same IP address space*
utilize multiple routing protocols within an autonomous system
utilize one public IP address to translate multiple private addresses
Which two statements describe classful IP addresses? (Choose two.)
It is possible to determine which class an address belongs to by reading the first bit.
Only Class A addresses can be represented by high-order bits 100.
Up to 24 bits can make up the host portion of a Class C address.
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.*
Three of the five classes of addresses are reserved for multicasts and experimental use.
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 [1/0] via 172.16.2.2*
C 172.16.1.0 [1/0] via 172.16.2.2
S 172.16.1.0 is directly connected, Serial0/0
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
Refer to the exhibit. Which is the best way for PC A and PC B to successfully communicate with sites on the Internet?
Configure a static route from R1 to ISP and a dynamic route from ISP to R1.
Configure a default route from R1 to ISP and a static route from ISP to R1.*
Configure a routing protocol between R1 and ISP and advertise all the routes.
Configure a dynamic route from R1 to ISP and a static route from ISP to R1.

What are two advantages of static routing over dynamic routing? (Choose two.)
Static routing uses fewer router resources than dynamic routing.*
Static routing scales well with expanding networks.
Static routing requires very little knowledge of the network for correct implementation.
Static routing is more secure because it does not advertise over the network.*
Static routing is relatively easy to configure for large networks.
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?
R2 needs a static route to the Internet.
R1 and R2 must use a dynamic routing protocol.
R1 needs a default route to R2.
R1 needs a static route to the R2 LAN.*
R2 needs a static route to the R1 LANs.

show ip interface brief*
show ip route*
