Study Notes

Network Functions and Architectures

End user devices require direct connectivity for efficient access.
Traffic policing is essential at the edge of the network to manage data flow.
Uninterrupted forwarding service is critical for maintaining network performance.
Packet inspection is necessary to detect and mitigate malicious activities.
Timely data transfer between different network layers enhances overall functionality.

Core Layer Functions

The collapsed core layer enforces routing policies in a two-tier architecture.

Cloud and Virtualization Concepts

Virtual machines run efficiently via hypervisors, enabling virtualization of physical components like CPU, memory, and storage.
Infrastructure-as-a-Service (IaaS) allows users to install custom operating systems on virtual machines.
Cloud services contribute to reducing energy costs and promoting telecommuting, supporting environmental sustainability.
A fundamental of virtualization includes enabling logical network devices to manage traffic between virtual machines and physical networks.

Virtual Machine Operations

Virtual machines are operating system instances that function independently from server hardware, facilitating resource management.
Access points connect wireless devices to wired networks, playing a vital role in enterprise connectivity.

Layer 3 Device Functionality

The primary role of a Layer 3 device is passing traffic between different networks.

SFP Module Interfaces

Both copper and fiber interfaces using SFP modules provide hot-swappable functionality, allowing minimal service interruption.

Topology Architectures

In spine-and-leaf architecture, each device is equidistantly separated by the same number of hops, ensuring efficient communication.
Three-tier network topologies consist of a core layer that guarantees connectivity continuity during device failures, and the distribution layer operates using both Layer 2 and Layer 3 technologies.
