Which two interfaces are considered overlay links? (Choose two.)

Answer options

• A. IPsec
• B. LAG
• C. Physical
• D. GRE

Correct answer: A, D

IPsec and GRE are both tunneling protocols that create overlay networks, allowing for secure and encapsulated communication over existing networks. LAG and Physical interfaces, on the other hand, refer to link aggregation and physical layer connections, respectively, which do not provide the overlay functionality.
