Which range of VLANs is referred to as the normal range?

1–1005
1006–4094
0–100
1–4094

The correct answer is: 1–1005

The range of VLANs referred to as the normal range is indeed from 1 to 1005. This range is defined in the IEEE 802.1Q standard and consists of VLANs that can be used in most basic network configurations. These VLANs are considered "normal" because they are available for users to implement within standard switch configurations, allowing for segmented network traffic and improved security. In contrast, the range from 1006 to 4094 is classified as the extended range and is typically used in more advanced configurations, often requiring specific switch features and capabilities. The range labeled as 0 to 100 is not valid as it includes VLAN IDs that do not align with the standard VLAN numbering. While VLAN 0 is reserved for priority tagging and VLAN 100 is part of the normal range, the beginning of the normal range starts at VLAN 1. Lastly, the entire range from 1 to 4094 includes both normal and extended ranges but does not specify the subset that falls under normal usage. Hence, the normal range is specifically from 1 to 1005, which is why this answer is accurate.
