NSE 7 – SD-WAN 7.0 — Question 29

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

Answer options

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

Correct answer: B, D

Explanation

IPsec and GRE are both protocols that encapsulate data for secure transmission over a network, making them overlay links. On the other hand, LAG (Link Aggregation Group) is a method for combining multiple network interfaces, and Physical refers to the actual hardware interfaces, neither of which are classified as overlay links.
