What is the difference between 'symmetric' routing and 'asymmetric' routing in networks?

Q: Answer-What is the difference between 'symmetric' routing and 'asymmetric' routing in networks?

Asymmetric routing commonly occurs on the internet where multiple paths exist i.e. a packet from A to B may take a different route than the reply from B to A. This can cause issues with stateful firewalls which track connection state and intrusion detection systems that may not see the complete conversation. Network administrators must account for asymmetric routing when designing security architectures for bank networks with multiple ISP connections multi-homing.

A Symmetric routing uses TCP and ensures that data is encrypted; asymmetric routing uses UDP and sends data packets without encryption

B Symmetric routing is secure and fast; asymmetric routing is less secure and slow

C In symmetric routing, traffic flows the same path in both directions; in asymmetric routing, forward and return paths may differ

D Symmetric routing is used in LANs; asymmetric routing is used in WANs only

E Symmetric routing requires more bandwidth; asymmetric routing uses less bandwidth
