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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change request ticket numbers are generated automatically by software rather than handwritten logs.
Why it's wrong here
Automated ticket generation is a best practice that improves auditability and traceability.
- ✗
Change request forms require the signature of the lead network architect rather than the CISO.
Why it's wrong here
Technical leads are often appropriately delegated to approve standard technical operational changes.
- ✗
Firewall change tickets are archived in a digital repository for only 12 months instead of 3 years.
Why it's wrong here
While a retention policy violation is a compliance finding, it represents a lower immediate operational risk than unapproved modifications.
- ✓
Network engineers implement emergency rule modifications directly in production without pre-testing or CAB approval.
Why this is correct
Unvetted and untested changes directly threaten network stability and can accidentally open critical security holes.
