Which two methods use IPsec to provide secure connectivity from the branch office to the headquarters office? (Choose two.)
The correct answer is A. DMVPN. DMVPN and Virtual Tunnel Interface (VTI) are two common methods that leverage IPSec to establish secure VPN tunnels, providing encrypted and authenticated connectivity between branch and headquarters offices.

Why each option
DMVPN and Virtual Tunnel Interface (VTI) are two common methods that leverage IPSec to establish secure VPN tunnels, providing encrypted and authenticated connectivity between branch and headquarters offices.
DMVPN (Dynamic Multipoint VPN) builds scalable and flexible VPN networks using mGRE and NHRP, relying on IPSec for encrypting and authenticating the tunnel traffic to secure communication between sites.
MPLS VPNs provide private network services over a shared MPLS backbone using labels for forwarding and do not inherently use IPSec for data plane security between customer sites.
SSL VPNs (Secure Sockets Layer VPNs) use SSL/TLS for encryption and authentication, typically for remote-access scenarios, but do not use IPSec for the underlying tunnel security.
