CompTIA Network+ Practice Test

Which type of network service allows for QoS and routing as part of its offerings?

1. Dynamic routing

2. Network as a Service (NaaS)

3. Static routing

4. Infrastructure as Code (IaC)

The correct answer is: Network as a Service (NaaS)

Network as a Service (NaaS) is the correct answer because it is a cloud-based service model that provides a range of networking services over the internet, including Quality of Service (QoS) and dynamic routing capabilities. NaaS enables organizations to access network resources on a subscription basis, leaving the underlying network management to the service provider. This model allows for flexible scalability and efficient resource allocation, incorporating QoS to prioritize traffic based on application needs, and using dynamic routing protocols to optimize data traffic across the network. Dynamic routing refers specifically to the methods used to automatically adjust routing paths based on current network conditions but does not encompass the broader networking services offered in a NaaS model. Static routing, on the other hand, involves manually configured routes that do not adapt to changing network conditions and therefore lack the features offered by NaaS. Infrastructure as Code (IaC) is focused on managing infrastructure through code and automation, separate from the network service aspects of QoS and routing.
