1. Which dynamic routing protocol was developed to interconnect different Internet service providers?
2. Which routing protocol is limited to smaller network implementations because it does not accommodate growth for larger networks?
3. What two tasks do dynamic routing protocols perform? (Choose two.)
update and maintain routing tables*
propagate host default gateways
assign IP addressing
4. When would it be more beneficial to use a dynamic routing protocol instead of static routing?
in an organization with a smaller network that is not expected to grow in size
on a stub network that has a single exit point
in an organization where routers suffer from performance issues
on a network where there is a lot of topology changes*
5. When would it be more beneficial to use static routing instead of dynamic routing protocols?
on a network where dynamic updates would pose a security risk*
on a network that is expected to continually grow in size
on a network that has a large amount of redundant paths
on a network that commonly experiences link failures
6. What is a purpose of the network command when configuring RIPv2 as the routing protocol?
It identifies the interfaces that belong to a specified network.*
It specifies the remote network that can now be reached.
It immediately advertises the specified network to neighbor routers with a classful mask.
It populates the routing table with the network entry.
7. A network administrator configures a static route on the edge router of a network to assign a gateway of last resort. How would a network administrator configure the edge router to automatically share this route within RIP?
Use the auto-summary command.
Use the passive-interface command.
Use the network command.
Use the default-information originate command.*
8. What is the purpose of the passive-interface command?
allows a routing protocol to forward updates out an interface that is missing its IP address
allows a router to send routing updates on an interface but not receive updates via that interface
allows an interface to remain up without receiving keepalives
allows interfaces to share IP addresses
allows a router to receive routing updates on an interface but not send updates via that interface*

S* 0.0.0.0/0 [1/0] via 172.16.1.1
13. Which two requirements are used to determine if a route can be considered as an ultimate route in a router’s routing table? (Choose two.)
be a default route
contain an exit interface*
be a classful network entry
contain a next-hop IP address*
14. What is a disadvantage of using dynamic routing protocols?
They are only suitable for simple topologies.
Their configuration complexity increases as the size of the network grows.
They send messages about network status insecurely across networks by default.*
They require administrator intervention when the pathway of traffic changes.
15. Which two statements are true regarding classless routing protocols? (Choose two.)
sends subnet mask information in routing updates*
sends complete routing table update to all neighbors
is supported by RIP version 1
allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology*
reduces the amount of address space available in an organization
16. Refer to the exhibit. Based on the partial output from the show ip route command, what two facts can be determined about the RIP routing protocol? (Choose two.)
RIP version 2 is running on this router and its RIP neighbor.*
The metric to the network 172.16.0.0 is 120.
RIP version 1 is running on this router and its RIP neighbor.
The command no auto-summary has been used on the RIP neighbor router.*
RIP will advertise two networks to its neighbor.
17. While configuring RIPv2 on an enterprise network, an engineer enters the command network 192.168.10.0 into router configuration mode.
What is the result of entering this command?
The interface of the 192.168.10.0 network is sending version 1 and version 2 updates.
The interface of the 192.168.10.0 network is receiving version 1 and version 2 updates.
The interface of the 192.168.10.0 network is sending only version 2 updates.*
The interface of the 192.168.10.0 network is sending RIP hello messages.
18. A destination route in the routing table is indicated with a code D. Which kind of route entry is this?
a static route
a route used as the default gateway
a network directly connected to a router interface
a route dynamically learned through the EIGRP routing protocol*
19. Refer to the exhibit. Which interface will be the exit interface to forward a data packet with the destination IP address 172.16.0.66?
20. Which type of route will require a router to perform a recursive lookup?
an ultimate route that is using a next hop IP address on a router that is not using CEF*
a level 2 child route that is using an exit interface on a router that is not using CEF
a level 1 network route that is using a next hop IP address on a router that is using CEF
a parent route on a router that is using CEF

a 192.168.14.0/26 route that is learned via RIP*
a 192.168.14.0/24 route that is learned via EIGRP

23. What is different between IPv6 routing table entries compared to IPv4 routing table entries?
IPv6 routing tables include local route entries which IPv4 routing tables do not.
By design IPv6 is classless so all routes are effectively level 1 ultimate routes.*
The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.
IPv6 does not use static routes to populate the routing table as used in IPv4.

25. Match the characteristic to the corresponding type of routing. (Not all options are used.)
Place the options in the following order:
[+] typically used on stub networks
[+] less routing overhead
[#] new networks are added automatically to the routing table
[#] best choice for large networks
