Exhibit
Change control evidence: - CHG-8842: "Allow vendor IP range for maintenance window" - Requested: 2026-04-18 09:10 - Reviewed by CAB: Approved 2026-04-18 11:40 - Implemented: 2026-04-18 22:05 - Post-change validation: Firewall logs show only the approved destination was opened - Separate email: "Looks fine to me" from engineer after implementation
Based on the exhibit, which artifact is the strongest evidence that the firewall change was reviewed and approved before implementation?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
The engineer's post-implementation email, because it confirms someone checked the change.
A post-change email is informal and does not prove formal approval happened before deployment.
Distractor review
The firewall logs, because they show the rule was applied successfully on the device.
Logs prove the change took effect, but they do not prove it was reviewed and authorized in advance.
Best answer
The change request record with CAB approval timestamp and implementation time.
This is the best evidence because it shows formal review and approval occurred before the change was implemented. Auditors want controlled, time-stamped proof of authorization, not just technical confirmation that the firewall rule changed or an informal email afterward. The change record directly supports compliance with change management requirements.
Distractor review
The vendor's maintenance notice, because it explains why the rule was needed.
The vendor notice may justify the request, but it does not show internal review, approval, or governance.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: The change request record with CAB approval timestamp and implementation time. — The change request record with the CAB approval timestamp is the strongest evidence because it proves formal review and authorization occurred before implementation. The exhibit includes both the approval time and the deployment time, which is exactly what an auditor needs to see. Post-change emails and firewall logs are useful supporting artifacts, but they do not by themselves establish proper change governance. Why others are wrong: An engineer's email is informal and happens after the fact, so it is weak audit evidence. Firewall logs show a technical result, not management approval. A vendor maintenance notice may explain why the change was requested, but it does not prove the organization reviewed and approved the change through its own control process.
