- A
Access the switch and enter privileged EXEC mode, then enter global configuration mode, then create the VLAN, then assign interfaces to the VLAN.
This is the correct order because you must first gain access to the switch, then enter the global configuration context, then define the VLAN, and finally assign ports to it.
- B
Access the switch and enter privileged EXEC mode, then create the VLAN, then enter global configuration mode, then assign interfaces to the VLAN.
Why wrong: This is incorrect because the VLAN must be created from within global configuration mode; attempting to create it before entering that mode would fail.
- C
Enter global configuration mode, then access the switch and enter privileged EXEC mode, then create the VLAN, then assign interfaces to the VLAN.
Why wrong: This is incorrect because you cannot enter global configuration mode without first being in privileged EXEC mode; the sequence must start with accessing the switch.
- D
Access the switch and enter privileged EXEC mode, then enter global configuration mode, then assign interfaces to the VLAN, then create the VLAN.
Why wrong: This is incorrect because you must create the VLAN before assigning ports to it; otherwise, the VLAN does not exist for the ports to be assigned to.
N10-009 Network Security Practice Question
This N10-009 practice question tests your understanding of network security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Drag and drop the steps to configure a VLAN on a managed switch into the correct order.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Access the switch and enter privileged EXEC mode, then enter global configuration mode, then create the VLAN, then assign interfaces to the VLAN.
VLAN creation involves entering config mode, creating the VLAN, and assigning ports.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

- ✓
Access the switch and enter privileged EXEC mode, then enter global configuration mode, then create the VLAN, then assign interfaces to the VLAN.
Why this is correct
This is the correct order because you must first gain access to the switch, then enter the global configuration context, then define the VLAN, and finally assign ports to it.
Related concept

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.

What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related N10-009 questions on access control and AAA configuration.
