CS320 Ch 4: Network Layer: Control Plane

T/F: If the size of a datagram is large and IPv6 cannot handle it, it would fragment it. This would require reassembly of the datagram at the receiver's side

False, IPv6 does not do fragmentation

T/F: In order to guarantee the integrity of data in a packet, checksum is necessary for both IPv4 and IPv6

False, checksum was removed in IPv6

T/F: In the Internet's network layer, forwarding refers to transferring the datagram from one router to another, while routing refers to transferring datagram from the input port of a router to its output port.

False, forwarding happens within the router and routing between routers

T/F: The remote control plane is implemented in the hardware of the routers. Routers compute the forwarding tables in order to interact with each other

False, it is not implemented in the hardware

T/F: While the dataplane operates at the milliseconds time scale, a router's control functions operate at the nanosecond timescale

False, it is the other way around

T/F: IPv4 and IPv6 are two Internet protocols which are not compatible

False, they are compatible

T/F: 111.111.111.111 is a broadcast destination IP address in the Internet

True

T/F: Because of DHCP's ability to automate the network-related aspect of connecting a host to a network, it is referred to as Plug-and-Play

True

T/F: Because of NAT technology, hosts from outside of a subnet wouldn't know the IP address of hosts within the subnet

True

T/F: In a router, switching fabric connects the router's input port to its output port

True

T/F: NAT technology isolates the subnet from the rest of the Internet and provides autonomy to the owner of a subnet to manage it

True

T/F: Queuing can happen in both the input and output port of a router

True

T/F: The Internet's address assignment is known as Classless Interdomain Routing (CIDR)

True

T/F: The Internet's network-layer packet is referred to as a datagram, whereas the transport layer packet is called a segment

True

T/F: The network service model guarantees the delivery of a packet within a specified host-to-host delay bound

True

T/F: The network service model is when multiple packets are sent, they will be delivered to the transport layer in the receiving host in the order in which they were sent

True

T/F: The router will forward the datagram to a programmed output port, based on the prefix of the IP address

True

T/F: Tunneling allows both the IPv4 and IPv6 to be used in today's Internet

True

T/F: If the 186.122.8.0/25 IP address is allocated to a subnet, this subnet an possess up to 64 hosts

[F]

T/F: Round Robin Queuing is the same as circular priority queuing

[F]

T/F: Round Robin algorithm is the most efficient way to manage packet scheduling in routers

[F]

T/F: The least significant bits in subnet addressing is referred to as a subnet mask

[F]

T/F: Fragmentation is dividing the file in many segments and it happens in the application layer

[False, it divides them into datagrams, not segments]

T/F: Classless Interdomain Routing (CIDR) introduces the notion of subnet addressing (a.b.c.d/x), where x represents the number of hosts within the subnet

[False]

T/F: In a router, the datagram with highest priority must be sent out to the following router first

[False]
