Match the OSPF packet type with the correct description.
sends specifically requested link-state records
acknowledges the other packet types
checks for database synchronization
requests specific link-state records from another router
discovers neighbo
Answer Options: LSAck, LSU, hello, LSR andDBD
Hello → discovers neighbors
Database Description (DBD) → checks for database synchronization
Link-State Request (LSR) → requests specific link-state records from another router
Link-State Update (LSU) → sends specifically requested link-state records
Link-State Acknowledgment (LSAck) → acknowledges the other packet types
Match the OSPF neighbor states on a LAN with their correct positions in the right order.
down
INIT
two-way
exstart
exchange
loading
full
Down → the router has not heard from the neighbor yet.
INIT → the router has heard a Hello from the neighbor, but the neighbor hasn’t seen this router yet.
Two-way → bidirectional communication is established; routers see each other in Hello packets.
ExStart → routers negotiate which one will start the database exchange.
Exchange → routers exchange Database Description (DBD) packets.
Loading → routers request and receive Link-State Advertisements (LSAs) to update their database.
Full → the routers are fully synchronized; neighbor relationship is complete.
What is a concern of the default OSPF metric on Cisco routers?
Links with speeds greater than 10 Gbps will not be supported until the release of OSPFv4.
Links with speeds greater than 1 Gbps are converted to 10 Mbps for the purposes of OSPF cost calculation.
Links with speeds greater than 100 Mbps have a cost of 1.
Links with speeds greater than 1 Gbps require additional memory in the OSPF router or switch to calculate the larger costs.
Links with speeds greater than 1 Gbps are converted to 10 Mbps for the purposes of OSPF cost calculation.
What is the function of an FHRP?
The FHRP supplies hosts with routing information.
The FHRP is a routing protocol.
The FHRP provides default gateway redundancy.
The FHRP is always standard-based.
The FHRP provides default gateway redundancy.
R1 and R2 routers in your company’s infrastructure are participating in HSRP group 1. R1 is the active router with a priority of 120 and R2 has the default priority. You accidently rebooted R1, and R2 became the active router. Once R1 is back online, which statement will be true?
R1 will always become the active router.
R2 will always remain the active router.
R1 will become the active router only if preempt is enabled.
Both routers will be in active state.
R1 will become the active router only if preempt is enabled.
You configured an important host in your company with a static default gateway pointing to one of the routers in the network. You also have a second router that can provide connectivity to other subnets. What will happen when the primary router fails and there is only a dynamic routing protocol configured between the routers?
The host will automatically discover the failure and update its default gateway with the IP address of the second router.
The second router will use the dynamic routing protocol to instruct the host to change its default gateway with its IP address.
The host should have DHCP provide the default gateway, so the DHCP server can dynamically update the gateway after the failure.
The host will lose connection to other subnets, since it cannot dynamically update the default gateway.
The host will lose connection to other subnets, since it cannot dynamically update the default gateway.
Which two options explain how a router learns destination networks? (Choose two.)
An administrator can enter routing information manually.
It learns from the desktop.
The router runs the dynamic routing process to learn prefixes from neighbor routers.
From any other devices that are not routable.
It learns from the servers.
An administrator can enter routing information manually.
The router runs the dynamic routing process to learn prefixes from neighbor routers.
Related to static routes, which statement is correct?
Static routes stay the same from the time they are configured.
Static routes will not stay the same; they will change automatically if there are changes in the network.
Static routes will set default routes when there are changes in the network.
Both static routes and dynamic route stay the same from the time they are configured.
Static routes stay the same from the time they are configured.
Which of these is a disadvantage of static routing?
scalability
security
simplicity
conserving router resources
scalability
Which two statements apply to dynamic routing protocols? (Choose two.)
Routers learn new networks by exchanging routing updates.
Dynamic routing protocols are unable to make changes to the routing table.
Unlike static routing, dynamic routing enables routers to select paths for non real-time network changes.
Dynamic routing protocols install a default route in the routing table to discover the neighbor.
Dynamic routing protocols automatically adjust routes when the topology or traffic changes.
Dynamic routing protocols keep the routes permanently (like static), even though there are changes in network.
Routers learn new networks by exchanging routing updates.
Dynamic routing protocols automatically adjust routes when the topology or traffic changes.
What is the purpose of link-state advertisements?
constructing a topological database
specifying the cost to reach a destination
determining the best path to a destination
verifying that a neighbor is still functioning
constructing a topological database
Which two options are classified as link-state routing protocols? (Choose two.)
IS-IS
OSPF
EIGRP
RIPv2
BGP
IS-IS
OSPF
The SPF algorithm uses a value that on a Cisco router is inversely proportional to the bandwidth. What is this value called?
link cost
hop count
link state
MTU
link cost
How do link-state protocols limit the scope of route changes?
by supporting classless addressing
by sending the mask along with the address
by sending only updates of a topology change
by segmenting the network into areas
by segmenting the network into areas
Which two data structures do the link-state routing protocols use? (Choose two.)
LSU database
neighbors database
link-state interfaces database

HSRP hello packets are sent to multicast address 224.0.0.5 on UDP port 1985.
HSRP hello packets are sent to multicast address 224.0.0.1 on TCP port 1985.

HSRP hello packets are sent to multicast address 224.0.0.2 on UDP port 1985.
You have been assigned a task to configure two routers as part of an HSRP group. Because you have not configured priority on the routers, which statement is correct?
Both routers will be in ACTIVE state.
Both routers will be in STANDBY state.
Both routers will be in LISTEN state.
One router will be in ACTIVE and the other in STANDBY state.
One router will be in ACTIVE and the other in STANDBY state.
