- A
Enter global configuration mode, diagnose interface with 'show interfaces', apply QoS policy, enable SNMP monitoring, verify with 'show running-config'.
This sequence follows the logical order: first enter configuration mode, then diagnose the interface, apply QoS, enable monitoring, and finally verify changes. It matches the standard troubleshooting workflow for network performance issues.
- B
Enable SNMP monitoring, enter global configuration mode, apply QoS policy, diagnose interface with 'show interfaces', verify with 'show running-config'.
Why wrong: This is incorrect because enabling monitoring before diagnosing the interface and applying QoS is out of order. Monitoring should be enabled after configuration changes to capture relevant data.
- C
Apply QoS policy, enter global configuration mode, diagnose interface with 'show interfaces', enable SNMP monitoring, verify with 'show running-config'.
Why wrong: This is incorrect because applying QoS before entering configuration mode is impossible; you must be in configuration mode to apply QoS. Also, diagnosis should precede configuration changes.
- D
Enter global configuration mode, apply QoS policy, diagnose interface with 'show interfaces', enable SNMP monitoring, verify with 'show running-config'.
Why wrong: This is incorrect because diagnosis should occur before applying changes. The agent must first understand the issue (diagnose) before applying a solution (QoS).
CCNA AI and Network Operations Practice Question
This 200-301 practice question tests your understanding of ai and network operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 following steps into the correct order for an agentic AI system to remediate a network performance issue using Cisco IOS-XE CLI commands.
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
Enter global configuration mode, diagnose interface with 'show interfaces', apply QoS policy, enable SNMP monitoring, verify with 'show running-config'.
The agent first enters configuration mode, then diagnoses the interface, applies QoS, enables monitoring, and finally verifies the changes.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

- ✓
Enter global configuration mode, diagnose interface with 'show interfaces', apply QoS policy, enable SNMP monitoring, verify with 'show running-config'.
Why this is correct
This sequence follows the logical order: first enter configuration mode, then diagnose the interface, apply QoS, enable monitoring, and finally verify changes. It matches the standard troubleshooting workflow for network performance issues.
Related concept
Authentication checks who the user is.
- ✗
Enable SNMP monitoring, enter global configuration mode, apply QoS policy, diagnose interface with 'show interfaces', verify with 'show running-config'.
Why it's wrong here
This is incorrect because enabling monitoring before diagnosing the interface and applying QoS is out of order. Monitoring should be enabled after configuration changes to capture relevant data.
- ✗
Apply QoS policy, enter global configuration mode, diagnose interface with 'show interfaces', enable SNMP monitoring, verify with 'show running-config'.
Why it's wrong here
This is incorrect because applying QoS before entering configuration mode is impossible; you must be in configuration mode to apply QoS. Also, diagnosis should precede configuration changes.
- ✗

Why it's wrong here
This is incorrect because diagnosis should occur before applying changes. The agent must first understand the issue (diagnose) before applying a solution (QoS).
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓Enter global configuration mode, diagnose interface with 'show interfaces', apply QoS policy, enable SNMP monitoring, verify with 'show running-config'.Correct answer▾
Why this is correct
This sequence follows the logical order: first enter configuration mode, then diagnose the interface, apply QoS, enable monitoring, and finally verify changes. It matches the standard troubleshooting workflow for network performance issues.
✗Enable SNMP monitoring, enter global configuration mode, apply QoS policy, diagnose interface with 'show interfaces', verify with 'show running-config'.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that SNMP monitoring should be enabled after QoS is applied, not before, to ensure the monitoring captures the effect of the QoS policy.
Why candidates choose this
Candidates might think monitoring should be enabled first to collect baseline data, but in remediation, the agent first diagnoses and applies changes, then enables monitoring to verify.
✗Apply QoS policy, enter global configuration mode, diagnose interface with 'show interfaces', enable SNMP monitoring, verify with 'show running-config'.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that QoS policies cannot be applied without first entering configuration mode. The order violates the CLI workflow.
Why candidates choose this
Candidates might mistakenly think QoS can be applied directly from privileged EXEC mode, or they may confuse the order of diagnosis and action.
✗Enter global configuration mode, apply QoS policy, diagnose interface with 'show interfaces', enable SNMP monitoring, verify with 'show running-config'.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that applying QoS before diagnosis is premature; the agent needs to identify the problem first. This order could lead to incorrect or unnecessary changes.
Why candidates choose this
Candidates might think that since the issue is known (performance), QoS can be applied immediately, but proper troubleshooting requires diagnosis first.

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 practitioner preparing for the 200-301 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
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 200-301 questions on access control and AAA configuration.
