Network Designs

A network topology where each node has a direct physical connection to every other node is called:

Mesh

Which type of network topology provides the highest level of redundancy?

Mesh

A type of network topology that combines two or more standard network topologies is referred to as a _______.

Hybrid network topology

A _______ is a network topology commonly used in LANs. In this topology, each node is connected directly to a central hub or switch.

Star topology

A _______, often used in WANs and VPNs, is a variation of the star topology. In this topology, a central hub connects to multiple spokes, each leading to different nodes, which offers slightly better fault tolerance than the star topology, as the failure of a single spoke does not disrupt the entire network.

Hub-and-spoke topology

Which of the answers listed below refers to a two-layer, full-mesh topology commonly used in data centers?

Spine and leaf

Which of the following examples fit the definition of a point-to-point topology?

WAN links, remote access connections, and VPN tunnels.

In the three-tier hierarchical model, the layer providing the backbone for the entire network is referred to as:

Core layer

Which of the answers listed below refer to the distribution layer of the three-tier hierarchical model?

Acts as an intermediary between the core and access layers and provides routing, filtering, and traffic management functions.

Which of the answers listed below describe the features of collapsed core network design?

Combines the core and distribution layers into a single layer, often deployed in small to medium-sized networks with limited traffic, and reduces complexity, lowers costs, and simplifies network management compared to the three-tier model.

A type of traffic flow between external networks (such as the Internet) and internal network resources (like servers or data centers) is known as:

North-south traffic

Which of the following terms is used to describe a traffic flow between devices within the same data center or network?

East-west traffic

Which of the following answers refer to the access layer of the three-tier hierarchical model?

Ensures that critical traffic receives priority over less important traffic (QoS),implements security measures to control network access, and provides the physical or wireless connections for end devices to access the network.
