A network engineer must simplify the IPsec configuration by enabling IPsec over GRE using IPsec profiles. Which two configuration changes accomplish this? (Choose two).

• A.Create an IPsec profile, associate the transform-set, and apply the profile to the tunnel interface.
• B.Remove all configuration related to crypto map from R1 and R2 and eliminate the ACL.
• C.Apply the crypto map to the tunnel interface and change the tunnel mode to tunnel mode ipsec ipv4.
• D.Remove the crypto map and modify the ACL to allow traffic between 10.10.0.0/24 to 10.20.0.0/24.
• E.Create an IPsec profile, associate the transform-set ACL, and apply the profile to the tunnel interface.

Which technology is used to provide Layer 2 and Layer 3 logical networks in the Cisco SD-Access architecture?

• A.underlay network
• B.VPN routing/forwarding
• C.easy virtual network
• D.overlay network

Correct Answer: D

Explanation

An overlay network creates a logical topology used to virtually connect devices that are built over an arbitrary physical underlay topology.
An overlay network is created on top of the underlay network through virtualization (virtual networks). The data plane traffic and control plane signaling are contained within each virtualized network, maintaining isolation among the networks and an independence from the underlay network.
SD-Access allows for the extension of Layer 2 and Layer 3 connectivity across the overlay through the services provided by through LISP.
