What is a commonality between DMVPN and FlexVPN technologies?
Correct Answer: D
In its essence, FlexVPN is the same as DMVPN. Connections between devices are still point-to-point GRE tunnels, spoke-to-spoke connectivity is still achieved with NHRP redirect message, IOS routers even run the same NHRP code for both DMVPN and FlexVPN, which also means that both are Cisco's proprietary technologies.

Question 522
What is the result of running the crypto isakmp key ciscXXXXXXXX address 172.16.0.0 command?
Correct Answer: A
Explanation The syntax of above command is: crypto isakmp key enc-type-digit keystring {address peer-address [mask] | ipv6 ipv6-address/ ipv6-prefix | hostname hostname} [no-xauth] The peer-address argument specifies the IP or IPv6 address of the remote peer.

Question 523
With which components does a southbound API within a software-defined network architecture communicate?
Correct Answer: D
The Southbound API is used to communicate between Controllers and network devices.
Question 524
What is the benefit of integrating Cisco ISE with a MDM solution?
What is an advantage of FlexVPN when compared to DMVPN?
Correct Answer: D
FlexVPN and DMVPN are both VPN technologies supported by Cisco, but they differ in their underlying protocols and flexibility: FlexVPN: This is a more versatile VPN solution based on IKEv2 and provides native support for IPsec, which is used to securely transmit routing information and establish connections. DMVPN: This relies on the Next Hop Resolution Protocol (NHRP) to dynamically discover and register endpoints, making it well-suited for scalable hub-and-spoke VPN topologies where spoke-to-spoke communication is desired.
