What is an advantage of MPLS Layer 3 VPN deployment?
An advantage of MPLS Layer 3 VPN deployment is that Quality of Service (QoS) is supported, providing predictable performance, the ability to enforce policies, and supporting multiple levels of service, including best-effort.
best effort is like no qos i stay with B
after more thinking the word connection-oriented is disturbing me IPSEC could be integrated between PE-PE and CE-CE Routers wich leads to answer D https://www.firewall.cx/cisco/cisco-routers/mpls-ip-vpn-security.html https://community.cisco.com/t5/service-providers-knowledge-base/static-ipsec-with-mpls-vpn/ta-p/3161428
In my opinion C sounds correct , with MPLS TE you can specify bandwidth of the links and have QOS B sounds more like DMVPN...
The answer is C
B is more DMPVN than MPLS l3 vpn(especially multipoint overlay part) C mpls l3 vpn can provide different levels of qos ie best effort, expedited etc..depends on customers finances and what the providers offers D mpls l3 vpns dont do encyption A feels more correct as its true customer will have to plan and possibly modify their internal networks before using mpls l3 vpn services
C is the only make sense.
B or C
Would probably go for B but arguably C is also right
Upon thought - B seems to describe DMVPN. Change answer to C as traffic engineering is a part of MPLS.
"MPLS Layer 3 VPNs use a peer-to-peer model that uses Border Gateway Protocol (BGP) to distribute VPN-related information. This highly scalable, peer-to-peer model allows enterprise subscribers to outsource routing information to service providers, resulting in significant cost savings and a reduction in operational complexity for enterprises." https://www.cisco.com/c/en/us/products/ios-nx-os-software/layer-3-vpns-l3vpn/index.html#:~:text=Cisco%20provides%20IP%20and%20MPLS,to%20distribute%20VPN%2Drelated%20information.
hard to tell on this one. Just used IA and checket other sites and B its the right one.
I would pick C. I do not think A is describing any advantage, so thats a no. For B the connection oriented part is odd. D i do not understand from MPLS VPN perspective
Migration for the end customer is simplified. There is no requirement to support MPLS on the CE router and no modifications are required for a customer intranet. - a) incorrect Scalability: Create scalable VPNs using connection-oriented, point-to-point overlays, Frame Relay, or ATM virtual connections. - b) Correct (Frame Relay y ATM son punto a multipunto) Integrated Quality of Service (QoS) support: QoS provides the ability to address predictable performance and policy implementation and support for multiple levels of service in an MPLS VPN. - c) incorrect Security: Security is provided at the edge of a provider network (ensuring that packets received from a customer are placed on the correct VPN) and in the backbone. - d) incorrect
