Cisco Exam 300-440 Topic 1 Question 16 Discussion

Actual exam question for Cisco's 300-440 exam

Question #: 16
Topic #: 1

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?

Ahub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS

Bstar topology with internet-based VPN connections and BGP for routing

Chybrid topology that combines MPLS and SD-WAN

Dfully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS

Show Suggested Answer

Suggested Answer: D

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:

This question has more acronyms than a tech support manual. I'm just going to close my eyes and point. Option A it is!

I'm not sure, this question is making my head spin like a top. Maybe I should just go with whatever has the most 'WAN' in the title. C or D, perhaps?
