A company wants to migrate its data and applications to the cloud to improve scalability and reduce operational costs. Which type of cloud computing model should they consider?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
For scalability and reduced operational costs, a Platform as a Service (PaaS) model is suitable as it provides a platform to develop, run, and manage applications without the complexity of infrastructure management.

- Bus
- Mesh
- Ring
- Star
A Star topology is characterized by a central node to which all other nodes are connected, forming a layout resembling a star.
In what topology do data packets travel from node to node in a ring, with each node having the chance to transmit?
- Bus
- Mesh
- Ring
- Star
In a ring topology, data packets travel from node to node in a ring, with each node having the chance to transmit when it receives control.
A company is expanding its network infrastructure and requires a setup that allows for easy scalability and centralized management. Which technology would best suit their needs?
- MPLS
- OSPF
- SD-WAN
