GETVPN Simplifies branch-to-branch instantaneous communications - Ensures low latency and jitter by enabling full-time, direct communications between sites, without requiring transport through a central hub
Maximizes security - Provides encryption for MPLS networks while maintaining network intelligence such as full-mesh connectivity, natural routing path, and quality of service (QoS)
Complies with governmental regulation and privacy laws - Helps you meet security compliance and internal regulation by encrypting all WAN traffic
Offers management flexibility - Eliminates complex peer-to-peer key management with group encryption keys

How can GETVPN reduce latency ? If I will not setup GETVPN, I will have to go via central hub ? No, so why the latency here. C is right answer , D is cisco marketing
D
"Helps ensure low latency and jitter by enabling full-time, direct communications between sites, without requiring transport through a central hub"
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_getvpn/configuration/xe-3s/sec-get-vpn-xe-3s-book/sec-get-vpn.html
D. 100% correct.
"Helps ensure low latency and jitter by enabling full-time, direct communications between sites, without requiring transport through a central hub"
"GET-based networks can be used in a variety of WAN environments, including IP and MPLS. MPLS VPNs that use this encryption technology are highly scalable, manageable, and cost-effective, and they meet government-mandated encryption requirements."

C is correct and D is wrong. GETVPN can reduce latency as it allows encrypted traffic to be transported over a pre-existing MPLS network. However, it does not necessarily eliminate the use of a central hub. In GETVPN, a group of routers called Key Servers act as a central hub for key management and security association management. So while GETVPN can provide encryption over MPLS, the use of a central hub is a key component of its design.
It does https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/content/en/us/td/docs/ios-xml/ios/sec_conn_getvpn/configuration/xe-16-6/sec-get-vpn-xe-16-6-book/sec-get-vpn-gikev2.html.xml
Yep...."The GETVPN G-IKEv2 feature implements Internet Key Exchange version 2 (IKEv2) protocol on GETVPN thereby allowing GETVPN to derive the benefits of IKEv2.":
I believe it's C as it does use a central hub for key management and security association.

"..Cisco Group Encrypted Transport VPN provides the following benefits:
Provides data security and transport authentication, helping to meet security compliance and internal regulation by encrypting all WAN traffic
Enables high-scale network meshes and eliminates complex peer-to-peer key management with group encryption keys
For Multiprotocol Label Switching (MPLS) networks, maintains network intelligence such as full-mesh connectivity, natural routing path, and quality of service (QoS)
Grants easy membership control with a centralized key server
Helps ensure low latency and jitter by enabling full-time, direct communications between sites, without requiring transport through a central hub
Reduces traffic loads on customer premises equipment (CPE) and provider-edge (PE) encryption devices by using the core network for replication of multicast traffic, avoiding packet replication at each individual peer site.."
