What is a difference between GETVPN and IPsec?
What is a difference between GETVPN and IPsec?
GETVPN reduces latency and provides encryption over MPLS without the use of a central hub. This is because GETVPN enables full-time, direct communications between sites without requiring transport through a central hub, thereby ensuring low latency and jitter. This approach allows encryption of traffic over MPLS networks while maintaining network intelligence such as full-mesh connectivity, natural routing path, and quality of service (QoS).
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

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.
key servers are for managment - not hub (= packets traverse via hub), nothing to do with data path and nothing to do with latency
'B" is correct answer. Question is regarding IPSEC differences. GET VPN currently supports only IKEv1.
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.":
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
I believe it's C as it does use a central hub for key management and security association. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_getvpn/configuration/xe-16-11/sec-get-vpn-xe-16-11-book/sec-get-vpn.html
Must have been asleep when looking into this. It's D.
"..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.."
Cisco wants you to choose D
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
I'll definitely answer A on this one. This looks like the fundamental difference between the two.
Answer correct D. Checked with securitytut
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." 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

This one is C
Helps ensure low latency and jitter by enabling full-time, direct communications between sites, without requiring transport through a central hub
I prefer D
C is the correct answer. Cheers
