Which algorithm provides encryption and authentication for data plane communication?
- A . AES-GCM
B. SHA-96
C. AES-256
D. SHA-384
Suggested Answer: A
Explanation:
The data plane of any network is responsible for handling data packets that are transported across the network.
(The data plane is also sometimes called the forwarding plane.)
Maybe this Qwants to ask about the encryption and authentication in the data plane of a SD-WAN network (but SD-WAN is not a topic of the SCOR 350-701 exam?).
In the Cisco SD-WAN network for unicast traffic, data plane encryption is done by AES-256-GCM, a symmetrickey algorithm that uses the same key to encrypt outgoing packets and to decrypt incoming packets. Each router periodically generates an AES key for its data path (specifically, one key per TLOC) and transmits this key to the vSmart controller in OMP route packets, which are similar to IP route updates.
