OSPF doesn't have a fast convergence time, which means that it can't quickly adapt to changes in the network topology
True
False
Which of the following statements is NOT true regarding OSPF?
OSPF is a link-state protocol that maintains information about the entire network topology.
OSPF has a fast convergence time, allowing it to quickly adapt to changes in the network topology.
OSPF is not scalable and can only support small networks with few routers and subnets.
OSPF supports the use of multiple paths between the same source and destination, allowing for load balancing and redundancy.
OSPF uses cost-based routing, which means that it selects the best path for data traffic based on the lowest cost, rather than the shortest path
True
False
Which of the following statements is true regarding OSPF?
OSPF only supports classful routing and cannot route IP packets to subnets of any size.
OSPF uses shortest-path routing, which means that it selects the path with the shortest distance for data traffic.
OSPF supports authentication to ensure that only authorized routers can participate in the network and exchange routing information.
OSPF does not support route summarization, which can lead to excessive routing traffic in large networks.

Circuit switching is a technique that directly connects the sender and the receiver in an broken path.
False
True
Disadvantages of Packet switching?
It can add some initial costs in implementation.
Possible long wait to establish a connection, (10 seconds, more on long- distance or international calls.) during which no data can be transmitted.
More expensive than any other switching techniques, because a dedicated path is required for each connection.
Inefficient use of the communication channel, because the channel is not used when the connected systems are not using it.
It is possible for a packet to be delivered if one of the nodes on its way is crashed momentarily. Thus all its queued packets may be lost.
False
True
In both packet switching methods, a message is broken into small parts, called packets.
