What is a purpose of the network command when configuring RIPv2 as the routing protocol?
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.
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.
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 parent route on a router that is using CEF
a level 1 network route that is using a next hop IP address on a router that is using CEF
an ultimate route that is using a next hop IP address on a router that is not using CEF
A router is configured to participate in multiple routing protocol: RIP, EIGRP, and OSPF. The router must send a packet to network 192.168.14.0. Which route will be used to forward the traffic?
a 192.168.14.0/24 route that is learned via EIGRP
a 192.168.14.0/25 route that is learned via OSPF
a 192.168.14.0/26 route that is learned via RIP
a 192.168.14.0/25 route that is learned via RIP
a 192.168.14.0/26 route that is learned via RIP
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 sending RIP hello messages.
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 only version 2 updates.
Which two statements are true regarding classless routing protocols? (Choose two.)
reduces the amount of address space available in an organization
allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
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
sends subnet mask information in routing updates
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
be a classful network entry
contain a next-hop IP address
contain subnets
contain an exit interface
contain a next-hop IP address
contain an exit interface
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?
O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0
S 10.1.0.0/16 is directly connected, GigabitEthernet0/0
S* 0.0.0.0/0 [1/0] via 172.16.1.1
C 192.168.10.0/30 is directly connected, GigabitEthernet0/1
O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0
When would it be more beneficial to use static routing instead of dynamic routing protocols?
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
on a network where dynamic updates would pose a security risk
Which route would be automatically created when a router interface is activated and configured with an IP address?
C 192.168.0.0/24 is directly connected, FastEthernet 0/0
O 172.16.0.0/16 [110/65] via 192.168.5.1
S 192.168.1.0/24 is directly connected, FastEthernet 0/1
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
What is the purpose of the passive-interface command?
allows a router to send routing updates on an interface but not receive updates via that interface
allows a router to receive routing updates on an interface but not send updates via that interface
allows a routing protocol to forward updates out an interface that is missing its IP address
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
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
in an organization where routers suffer from performance issues
on a network where there is a lot of topology changes
on a stub network that has a single exit point
on a network where there is a lot of topology changes
What is a disadvantage of using dynamic routing protocols?
They send messages about network status insecurely across networks by default.
They are only suitable for simple topologies.
They require administrator intervention when the pathway of traffic changes.
Their configuration complexity increases as the size of the network grows.
They send messages about network status insecurely across networks by default.
