I don't think you can debunk this with a generic CCNP check. The concern is hacking, not normal network configurations. The Uninterruptible power supply (UPS) provider is Palantir. Tabulator Machine <- usb/serial -> UPS <- cell connection -> Internet. Not uncommon to run SNMP on a UPS either. SNMP is an unloved pile of bugs: https://arstechnica.com/security/2025/09/as-many-as-2-million-cisco-devices-affected-by-actively-exploited-0-day/ https://arstechnica.com/security/2025/09/as-many-as-2-millio... I'm not saying anything nefarious actually happened. But as soon as you connect devices to the net in any way you are in deep water, especially when one or more of your vendors may be one of your threat actors. Complicated hacks are not common, but possible, especially when the stakes are high and competent people are on the task. Stuxnet development started 20 years ago - and the target was even airgapped, which didn't help the target in the end.
