A municipal wireless controller needs a security-related code upgrade. What practice best reflects controlled software upgrade management?
Select an answer to reveal the explanation.
Short Explanation
Treat controller code like changing the engine—pick a quiet window and keep the old parts handy. Save rollback config before you upgrade. Midday heroics without a back-out plan are how civic Wi-Fi becomes the headline.
Full Explanation
Controlled software upgrades for WLAN security infrastructure are scheduled in maintenance windows with rollback configurations preserved. This reduces outage impact and enables rapid recovery if the new code misbehaves. Unscheduled production upgrades without rollback violate sound change and maintenance practice.
