350-701 Practice Question: Secure Network Access, Visibility and Enforcement
This 350-701 practice question tests your understanding of secure network access, visibility and enforcement. 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.
The ISE logs show 'Authentication failed - RADIUS attribute Calling-Station-ID is missing' for a wired client. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The switch is not configured to include the calling-station-id in RADIUS requests.
Option D is correct because the switch must be configured to include the calling-station-id (MAC address) in RADIUS requests; if not, the attribute is missing. Option A is incorrect because the MAC address not being registered would cause a different failure. Option B is incorrect because 'authentication mac-move deny' affects MAC mobility, not attribute delivery. Option C is incorrect because trunk ports do not affect 802.1X authentication.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The switch is not configured to include the calling-station-id in RADIUS requests.
Why this is correct
The switch must send the MAC address via the Calling-Station-ID attribute; if not configured, it is missing.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
The switch is configured with 'authentication mac-move deny'.
Why it's wrong here
This command prevents MAC movement, not attribute inclusion.
✗
The switch port is configured as a trunk port.
Why it's wrong here
Trunk ports can still perform 802.1X; this does not cause missing calling-station-id.
✗
The client's MAC address is not registered in ISE.
Why it's wrong here
A missing MAC in ISE leads to 'user not found' errors, not missing attribute.
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.
Trap categories for this question
Command / output trap
This command prevents MAC movement, not attribute inclusion.
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 350-701 questions on access control and AAA configuration.

What is the correct answer to this question?
The correct answer is: The switch is not configured to include the calling-station-id in RADIUS requests. — Option D is correct because the switch must be configured to include the calling-station-id (MAC address) in RADIUS requests; if not, the attribute is missing. Option A is incorrect because the MAC address not being registered would cause a different failure. Option B is incorrect because 'authentication mac-move deny' affects MAC mobility, not attribute delivery. Option C is incorrect because trunk ports do not affect 802.1X authentication.
