Which algorithm provides encryption and authentication for data plane communication?
Correct 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.

Question 78
What is a commonality between DMVPN and FlexVPN technologies?
Correct Answer: B
FlexVPN uses NHRP for name resolution I believe. If you pay close attention to the option, it's saying it's the IOS is running the same NHRP being used, which is accurate as it's the build on the IOS. FlexVPN NHRP is primarily used to establish spoke to spoke communication.
Question 79
An administrator is trying to determine which applications are being used in the network but does not want the network devices to send metadata to Cisco Firepower. Which feature should be used to accomplish this?
Correct Answer: A
Explanation: NetFlow is a network protocol developed by Cisco for the collection and monitoring of network traffic flow data generated by NetFlow-enabled routers and switches. The flows do not contain actual packet data, but rather the metadata for communications. It is a standard form of session data that details who, what, when, and where of network traffic -> Answer A is not correct.
