Network Protocols II Final Exam Study Guide

A comprehensive set of flashcards covering essential vocabulary and definitions related to network protocols, cloud computing, virtualization, data centers, and WAN technologies covered in the study guide.

Cloud Computing

Offloads processing and storage to the internet, not local or LAN-based storage.

SaaS (Software as a Service)

Use of applications over the internet, such as Office 365 and Google Docs.

PaaS (Platform as a Service)

Build and deploy applications without managing infrastructure, exemplified by AWS platform services.

IaaS (Infrastructure as a Service)

Virtual servers and networks providing full control; examples include AWS EC2 and Azure VM.

FaaS (Function as a Service)

Serverless functions like AWS Lambda that allow running code without managing servers.

IDaaS (Identity as a Service)

Authentication and identity management services, such as Okta.

Public Cloud

A shared environment that is cheaper and scalable for multiple users.

Private Cloud

A more secure environment that is costly and highly customizable.

Hybrid Cloud

Combines both public and private clouds, offering flexibility.

Data Center

Facility that hosts servers and networking gear, requiring redundancy, cooling, and security.

SAN (Storage Area Network)

A dedicated network for storage purposes.

NAS (Network Attached Storage)

Storage that shares a LAN with lower cost and performance.

3-tier Network Design

Includes Access, Distribution, and Core layers for network architecture.

Switch

Operates at Layer 2 in the OSI model, connecting devices within a local area network.

Router

Operates at Layer 3, connecting multiple networks and directing traffic.

Managed Switch

A customizable switch capable of remote management through interfaces.

Unmanaged Switch

A plug-and-play switch with no customization capabilities.

Hypervisor

Software that allows multiple virtual servers to run on a single physical host.

Type 1 Hypervisor

A bare-metal hypervisor that operates directly on hardware.

Type 2 Hypervisor

A hosted hypervisor that runs on top of an operating system.

WAN (Wide Area Network)

Connects local area networks across geographical locations.

MPLS (Multiprotocol Label Switching)

A method for efficient packet labeling and routing in modern WANs.

SD-WAN (Software Defined WAN)

A virtualized WAN that uses software to control WAN connections.
