2.3 Flashcards
Which dynamic routing protocol was developed to interconnect different Internet service providers?
BGP
EIGRP
OSPF
RIP
BGP
Which routing protocol is limited to smaller network implementations because it does not accommodate growth for larger networks?
OSPF
RIP
EIGRP
IS-IS
RIP
What two tasks do dynamic routing protocols perform? (Choose two.)
discover hosts
update and maintain routing tables
propagate host default gateways
network discovery
assign IP addressing
update and maintain routing tables
network discovery
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
on a network where there is a lot of topology changes
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
on a network where dynamic updates would pose a security risk
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.
It identifies the interfaces that belong to a specified network.
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.
Use the default-information originate command.
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
allows a router to receive routing updates on an interface but not send updates via that interface
Which route would be automatically created when a router interface is activated and configured with an IP address?
D 10.16.0.0/24 [90/3256] via 192.168.6.9
C 192.168.0.0/24 is directly connected, FastEthernet 0/0
S 192.168.1.0/24 is directly connected, FastEthernet 0/1
O 172.16.0.0/16 [110/65] via 192.168.5.1
C 192.168.0.0/24 is directly connected, FastEthernet 0/0
Refer to the exhibit. Which two types of routes could be used to describe the 192.168.200.0/30 route? (Choose two.)
ultimate route
level 1 parent route
level 1 network route
level 2 child route
supernet route
ultimate route
level 2 child route
What occurs next in the router lookup process after a router identifies a destination IP address and locates a matching level 1 parent route?
The level 2 child routes are examined.
The level 1 supernet routes are examined.
The level 1 ultimate routes are examined.
The router drops the packet.
The level 2 child routes are examined.
Which route would be used to forward a packet with a source IP address of 192.168.10.1 and a destination IP address of 10.1.1.1?
C 192.168.10.0/30 is directly connected, GigabitEthernet0/1
S 10.1.0.0/16 is directly connected, GigabitEthernet0/0
O 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 172.16.1.1
O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0
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.)
contain subnets
be a default route
contain an exit interface
be a classful network entry
contain a next-hop IP address
contain an exit interface
contain a next-hop IP address
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.
They send messages about network status insecurely across networks by default.
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
sends subnet mask information in routing updates
allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
