Cisco Certified Network Associate (CCNA) Practice Exam

What is the range of VLANs that can be edited in a Cisco environment?

1. 1 - 1,000

2. 2 - 1,001

3. 1 - 2,000

4. 2 - 4,000

The correct answer is: 2 - 1,001

In a Cisco environment, the valid range of VLANs that can be configured spans from 1 to 4096, but there are specific VLANs that are reserved for system use and administrative purposes, which limits the range that can be actively managed by users. VLANs 1 and 1024 through 4095 are generally off-limits or reserved for specific functions. This means VLANs that users can actively edit and manage are typically from 2 to 1,001 when adhering to standard practices. Hence, for user-configurable VLANs, the valid range effectively becomes 2 through 1,001, which allows for an adequate number of VLANs for most organizational needs without conflicting with the reserved or system VLANs. This focused range provides flexibility while ensuring that the critical system VLANs are preserved for network stability and management tasks. Therefore, the correct answer aligns with the range of user-configurable VLANs within a typical Cisco setup.
