Question 7
A company with multiple branch offices wants a suitable connectivity model to meet these network architecture requirements:
high availability
quality of service (QoS)
multihoming
specific routing needs
Which connectivity model meets these requirements?
hub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS
star topology with internet-based VPN connections and BGP for routing
hybrid topology that combines MPLS and SD-WAN
fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS
Correct answer: D
Explanation:
A fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS meets the network architecture requirements of the company. A fully meshed topology provides high availability by eliminating single points of failure and allowing multiple paths between branch offices. SD-WAN technology enables multihoming by supporting multiple transport options, such as MPLS, internet, LTE, etc. SD-WAN also provides QoS by applying policies to prioritize traffic based on application, user, or network conditions. Dynamic routing allows the SD-WAN solution to adapt to changing network conditions and optimize the path selection for each traffic type. A fully meshed topology with SD-WAN technology can also support specific routing needs, such as segment routing, policy-based routing, or application-aware routing.Reference:Designing and Implementing Cloud Connectivity (ENCC) v1.0[Cisco SD-WAN Design Guide][Cisco SD-WAN Configuration Guide]
