Refer to the exhibit. When Router D
is configured to use a link-state routing protocol and is added to the
network, what is the first thing that it does to begin learning the
network topology?
It learns about its directly connected networks when its interfaces reach the up state.
What two events will cause a link state router to send LSPs to all neighbors? (Choose two.)
whenever the network topology changes
upon initial startup of router or routing protoc... Continue reading...

Refer to the exhibit. What can be determined from this output?
All of the routes listed are network routes.
Refer to the exhibit. A packet destined for host 128.107.0.5/16 is
processed by the JAX router. After finding the static route in the
routing table that matches the destination network for this packet,
what does the router do next?
performs a recursive lookup to find the exit interface used to forward the packet

Rip version 2 will auto summarize routes by default.
Refer to the exhibit. Which two statements are true? (Choose two.)
Router1 will install a route to 192.168.0.0/20
Router2 will not install a route to 192.168.16.0/20
Refer to the exhibit. Which command on which router will allow Router1 to learn about the 192.168.0.0/20 network?
Router2(c... Continue reading...

Refer to the exhibit. The network that
is shown is running RIPv1. The 192.168.10.0/24 network was recently
added and will only contain end users. What command or set of commands
should be entered on Router1 to prevent RIPv1 updates from being sent
to the end user devices on the new network while still allowing this
new network to be advertised to other routers?
Router1(config-router)# passive-interface fastethernet 0/0
The following line was displayed in ... Continue reading...

From: http://p4s-ccna.blogspot.comWhich event will cause a triggered update?
a route is installed in the routing table
Three routers running a distance-vector routing protocol lost all
power, including the battery backups. When the routers reload, what
will happen?
They will send updates that include only directly connected routes to their directly connected neighbors.
What does the RIP holddown timer do?
instructs routers to ignore updates, for a specified time or event, about possi... Continue reading...

From: http://p4s-ccna.blogspot.comWhich two statements correctly describe the concepts of administrative distance and metric? (Choose two.)
Administrative distance refers to the trustworthiness of a particular route.
Routes with the smallest metric to a destination indicate the best path.
Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?
R1 will install an EIGRP route
using network B in its routing table because the administrative
distance ... Continue reading...

Which of the following are displayed by the Router# show cdp neighbors command? (Choose three.)
platform
holdtime
local interface
Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network?
In a multi-access network, the router cannot determine the
next-hop MAC address for the Ethernet frame without a next-hop address.
The output of the Router# show interfaces serial 0/1 command displays th... Continue reading...
