Exam 300-410 topic 1 question 513 discussion

In my opinion C sounds correct , with MPLS TE you can specify bandwidth of the links and have QOS B sounds more like DMVPN...

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

An advantage of MPLS Layer 3 VPN deployment is its enhanced scalability and efficient resource utilization. By using a peer-to-peer model and distributing VPN-related information through Border Gateway Protocol (BGP), L3VPNs allow service providers to handle a large number of customers and connections without significantly increasing operational complexity. This, coupled with the flexibility of connection-oriented or connectionless options, makes it well-suited for businesses with multiple locations and complex networking needs. Additionally, MPLS L3VPNs offer features like Quality of Service (QoS) and traffic engineering to optimize network performance and ensure reliable connectivity

C is corerct

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

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

hard to tell on this one. Just used IA and checket other sites and B its the right one.

C is the only make sense.

"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.

best effort is like no qos i stay with B

Would probably go for B but arguably C is also right

B or C

The answer is C
