Cisco Exam 300-440 Topic 4 Question 14 Discussion

Actual exam question for Cisco's 300-440 exam
Question #: 14
Topic #: 4
[All 300-440 Questions]

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?

Show Suggested Answer Hide 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:

Star topology with internet-based VPN connections and BGP for routing? Really? I think that's a little outdated, don't you think?

I prefer option A, hub-and-spoke topology with MPLS for specific routing needs.

Fully meshed topology with SD-WAN technology? Sign me up! Dynamic routing and prioritized traffic for QoS - that's the future right there.

Multihoming, you say? I'm more of a unihoming kind of guy myself, but to each their own.

Wait, did someone say MPLS? I thought that was a new kind of sandwich. My bad, carry on.

MPLS is not a sandwich, it's a type of network connectivity.
