Which organization developed the OSPF protocol?
Microsoft
Cisco
Internet Engineering Task Force (IETF)
What is the purpose of dividing an Autonomous System (AS) into areas in OSPF?
To increase network complexity
To reduce LSDB size and improve scalability
To limit the number of routers in the network
To slow down network convergence
Which type of router belongs to two or more areas in OSPF?
Internal router
Area Border Router (ABR)
AS Boundary Router (ASBR)
Backbone Router
What is the purpose of the backbone area in OSPF?
To slow down network convergence
To limit the number of routers in the network
To forward inter-area routing information
To increase LSDB size
What is the purpose of specifying an area for each OSPF interface?
To increase network complexity
To limit the number of routers in the network
To reduce LSDB size and improve scalability
To slow down network convergence
What is the advantage of using OSPF over RIP in terms of scalability?
OSPF supports VLSM and CIDR for efficient IP address allocation
OSPF has a lower administrative distance for faster route convergence
OSPF uses hop count as the metric for path selection
OSPF does not support authentication between routers
What is the significance of the OSPF Hello packets in neighbor discovery?
Hello packets are used to establish and maintain neighbor adjacencies
Hello packets contain the entire routing table information
Hello packets are sent only when there is a change in the network topology
Hello packets are encrypted for secure communication
Which protocol data unit (PDU) is equivalent to a packet in IS-IS?
Link State Request
omplete Sequence Number PDU
Link State PDU
Hello PDU
What is the purpose of the SPF routing algorithm in IS-IS?
Calculate Shortest Path
Send Sequence Numbers
Establish Adjacencies
Flood LSPs
What is the main difference between RIPv1 and RIPv2?
RIPv1 has a hop limit of 10, RIPv2 has a hop limit of 15
RIPv1 is classful, RIPv2 is classless
RIPv1 uses multicast, RIPv2 uses unicast
RIPv1 includes subnet masks, RIPv2 does not
What type of routing protocol is RIP v2?
Path-vector
Link-state
Distance-vector
Hybrid
What does ES stand for in the IS-IS vs OSPF terminology?
Host
Router
Link
Packet
Which protocol data unit (PDU) is equivalent to a packet in IS-IS?

How do network administrators manage the flow of computer network traffic within a controlled network?
Link State Protocol
Distance Vector Protocol
Border Gateway Protocol
Path Vector Protocol
Bandwidth is not a main components of dynamic routing.
True
False
Synchronous is a charatceristic of distance vector routing where it does not require that all of its nodes operate in the lock step with each other.
True
False
Dynamic Routing is type of routing that smart enough to take the best path for data based on the condition of the network.
True
False
Distance vector routing where each router maintains a distance table known as Link State.
True
False
Link state protocols use characteristics of the route such as speed and cost as well as current congestion to determine the best path, which is typically computed by Dijkstra Algorithms .
True
False
In EIGRP, information about all destination networks
reported by the neighbors is stored in (a) table.
If the default hello interval in EIGRP is 60 seconds, therefore its default hold time is (a) seconds.
The first and the second-best paths for each route are stored in (a) table.
RIPv2 (a) the entire routing table to all adjacent routers at the address 224.0.0.9
In the global configuration mode, (a) command is used
to enter into the routing configuration setting.
OSPF Version 2, defined in RFC (a) , is intended for IPv4.
OSPF uses (a) algorithm.
(a) this routing command allows you to change router name.
The administrative distance of internal EIGRP is (a) .
EIGRP uses bandwidth, (a) , load, and reliability to calculate the metric for its routing table.
