What is a difference between DMVPN and sVTI?
The correct answer is B. DMVPN supports dynamic tunnel establishment, whereas sVTI does not.. DMVPN supports dynamic on-demand tunnel establishment between spokes, a feature not inherently provided by static Virtual Tunnel Interface (sVTI) configurations.

Why each option
DMVPN supports dynamic on-demand tunnel establishment between spokes, a feature not inherently provided by static Virtual Tunnel Interface (sVTI) configurations.
Both DMVPN and sVTI rely on IPsec for tunnel encryption.
DMVPN (Dynamic Multipoint VPN) is designed for dynamic creation of spoke-to-spoke tunnels on demand, eliminating the need for a full mesh of static tunnels. sVTI, while supporting IPsec, typically requires pre-configured static tunnel interfaces.
Both DMVPN and sVTI can be configured for static tunnel establishment, though DMVPN's primary advantage is dynamic.
Both DMVPN and sVTI are Cisco-specific implementations but operate using standard IPsec protocols, which allows for some interoperability with other vendors supporting standard IPsec.
