Transport Architecture

Question 1

Management Plane

Answer 1

Handles the configuration, monitoring, software updates and security management. Employs Protocols like Simple Network Management Protocol (SNMP) and Network Configuration Protocol (NETCONF)

Question 2

Control Plane

Answer 2

Responsible for managing network routing protocols that facilitate communication between devices on the network. Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP)

Question 3

Data Plane

Answer 3

Responsible for forwarding data packets between devices in the network. Uses protocols such as Ethernet and Internet Protocol (IP) to perform its functions

Question 4

Cut Through Switching

Answer 4

Begins forwarding the frame as soon as the destination address is identified. In the approach, switches do not drop invalid frames but forward them to the next node. However, the network latency is lower. Use this when ultra-low latency is important and cost/simplicity is a high priority.

Question 5

Store and Forward Switching

Answer 5

Waits until the entire frame has arrived before forwarding it. This method stores the entire frame in memory. In memory the switch checks the destination address, source address, and the CRC. If no errors are present, the frame is forwarded to the appropriate port.
This method creates a higher latency. Use this when reliability is essential or network is less reliable.
