Question 1mediumdrag order
Open the full VLAN trunking answer →Question 1,128 of 2,015
Quick Answer
The correct order for VLAN mapping on trunk interfaces is: first enter the trunk interface configuration mode, then configure the encapsulation type, next apply the VLAN mapping policy using either the translate or map command, and finally verify the mapping with show vlan mapping. This sequence is correct because VLAN mapping requires the trunk interface to be properly defined and its encapsulation set before any translation or mapping rules can be applied; the verification step always comes last to confirm the policy is active. On the ENCOR 350-401 exam, this drag-and-drop task tests your understanding of the procedural flow for implementing VLAN translation on a trunk, often appearing as a step-ordering question where a common trap is placing verification before applying the policy. A helpful memory tip is "Interface, Encapsulation, Map, Verify" — or simply "I Enter My VLAN" to recall the order from first to last.
350-401 VLANs and Trunking Practice Question
This 350-401 practice question tests your understanding of vlans and trunking. 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.

Correct answer & explanation
✓
Enter trunk interface configuration mode
First enter the trunk interface, configure encapsulation, then apply the VLAN mapping policy (translate or map), and finally verify the mapping.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 350-401 questions on access control and AAA configuration.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop the steps of VLAN mapping on trunk interfaces into the correct order, from first to last.
medium- ✓ A.Enable VLAN mapping globally with vlan mapping enable
- ✓ B.Enter interface configuration mode for the trunk
- ✓ C.Configure the interface as trunk with switchport mode trunk
- ✓ D.Apply VLAN mapping with vlan mapping <old> <new>
- ✓ E.Verify mapping with show vlan mapping
Why A: VLAN mapping requires first enabling the feature globally, then configuring the trunk interface, mapping the VLANs, and finally verifying the translation. The order ensures proper translation between customer and service provider VLANs.
