In Huawei's SD-WAN solution, which of the following security technologies can ensure the security of communication between branches and headquarters/cloud, preventing data leakage?
(Multiple choice)

• A.Data is transmitted in plaintext, without encryption or authentication mechanisms.
• B.Application layer firewall (filters unauthorized application traffic, such as malicious attacks)
• C.Identity authentication (e.g., branch devices accessing the SD-WAN network via certificate authentication)
• D.Turn off the firewall and allow all traffic to pass through .
• E.IPsec encrypted tunnel (encrypts transmitted data packets)
