What type of document is commonly associated with a table of VLANs that includes the devices performing routing services?

The correct answer is associated with the Low Level Design (LLD) document, which provides detailed specifications on the network infrastructure, including the configuration of devices such as routers and switches. In this context, an LLD typically includes a table of VLANs and specific information about how routing services will be implemented within the network.

LLDs are crucial for translating the broader concepts outlined in a High Level Design (HLD) into actionable configurations and settings. They provide the granular detail needed for engineers to implement the network, covering various elements such as IP addressing schemes, VLAN assignments, and routing protocols, all organized in a structured manner. This type of documentation ensures that everyone involved in the project has a clear understanding of how the network will be set up and managed.

While a High Level Design document outlines the overall architecture and vision for the network, it does not delve into the specifics of VLANs or the routing processes. The Operational Design Document focuses more on processes and procedures rather than specific technical configurations. The Routing Design Document, although it sounds pertinent, is not a standard term like LLD and may not comprehensively cover the VLAN table and routing details as expected in a typical LLD. Thus, the Low Level Design is the most appropriate choice in this scenario
