Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 140

The network administrator creates VLAN 10 and assigns an IP address to VLANIF10. When using the command "display ip interface brief", the administrator finds that VLANIF10 is down. What should be done to enable VLANIF10?

Answer options

• A. Use the command "undo shutdown" under the interface view for VLANIF10
• B. Assign a physical interface that has either an active of inactive physical state to VLAN 10
• C. Assign only a physical interface that has an active physical state to VLAN 10
• D. Add an interface that has an active physical state and a trunk port associated with VLAN 10

Correct answer: C

Explanation

The correct answer, C, is accurate because VLANIF10 needs a physical interface that is actively operational to become active itself. Options A and B do not ensure that the interface is in an active state, while D requires a trunk port, which is not necessary for the basic activation of VLANIF10.
