What are two functions of a router? (Choose two.)
It connects multiple IP networks.
It controls the flow of data via the use of Layer 2 addresses.
It determines the best path to send packets.
It manages the VLAN database.

3
Which statement describes a route that has been learned dynamically?
It is automatically updated and maintained by routing protocols.
It is unaffected by changes in the topology of the network.
It has an administrative distance of 1.
It is identified by the prefix C in the routing table.
4
Which statement is correct about IPv6 routing?
IPv6 routing is enabled by default on Cisco routers.
IPv6 only supports the OSPF and EIGRP routing protocols.
IPv6 routes appear in the same routing table as IPv4 routes.
IPv6 uses the link-local address of neighbors as the next-hop address for dynamic routes.
5
Which three advantages are provided by static routing? (Choose three.)
Static routing does not advertise over the network, thus providing better security.
Configuration of static routes is error-free.
Static routes scale well as the network grows.
Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does.
The path a static route uses to send data is known.
No intervention is required to maintain changing route information.

Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet. How should this static route be changed to allow user traffic from the LAN to reach the Internet?
Add the next-hop neighbor address of 209.165.200.226.
Change the exit interface to S0/0/1.
Change the destination network and mask to 0.0.0.0 0.0.0.0.0.

10.50.0.0/28
10.50.0.128/26
10.50.0.40/29
A company branch office has recently added an IP-based video surveillance system that requires a server and 20 cameras to be on a separate network. Which network number and mask could be used for this network if the branch office is using an overall block of addresses of 10.50.0.0/24?
10.50.0.32/27

11
What does the cost of an OSPF link indicate?
A higher cost for an OSPF link indicates a faster path to the destination.
Link cost indicates a proportion of the accumulated value of the route to the destination.
Cost equals bandwidth.
A lower cost indicates a better path to the destination than a higher cost does.

Refer to the exhibit. Which statement is supported by the output?
A static default route has been manually configured on this router.
Summarization of routes has been manually configured.
A default route is being learned through an external process.
The route to 192.168.1.1 represents the configuration of a loopback interface.
25
When should EIGRP automatic summarization be turned off?
when a router has not discovered a neighbor within three minutes
when a router has more than three active interfaces
when a network contains discontiguous network addresses
when a router has less than five active interfaces
when a network addressing scheme uses VLSM
26
Which three statements are advantages of using automatic summarization? (Choose three.)
It maximizes the number of routes in the routing table.
It increases the size of routing updates.
It reduces the frequency of routing updates.
It ensures that traffic for multiple subnets uses one path through the internetwork.
It improves reachability in discontiguous networks.
It decreases the number of entries in the routing table.
27
A router is participating in an OPSFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OPSF router?
OSPF will run a new DR/BDR election.
SPF will run and determine which neighbor router is “down”.
A new dead interval timer of 4 times the hello interval will start.
OSPF will remove that neighbor from the router link-state database.
28
What happens immediately after two OSPF routers have exchanged hello packets and have formed a neighbor adjacency?
They exchange DBD packets in order to advertise parameters such as hello and dead intervals.
They negotiate the election process if they are on a multiaccess network.
They request more information about their databases.
They exchange abbreviated lists of their LSDBs.
29
In an OSPFv2 configuration, what is the effect of entering the command network 192.168.1.1 0.0.0.0 area 0?
It changes the router ID of the router to 192.168.1.1.
It enables OSPF on all interfaces on the router.
It tells the router which interface to turn on for the OSPF routing process.
It allows all 192.168.1.0 networks to be advertised.
30
What is the reason for a network engineer to alter the default reference bandwidth parameter when configuring OSPF?
to more accurately reflect the cost of links greater than 100 Mb/s
to increase the speed of the link
to force that specific link to be used in the destination route
to enable the link for OSPF routing
