IT proposes an inline TLS-inspecting proxy in front of a 10 ms cyclic exchange between a controller and its drives. What is the biggest concern?
- A.Added jitter can break deterministic cycle timing
- B.Proxy certificates expire sooner on controllers
- C.Inspection raises the controller CPU temperature
- D.Packet captures violate protocol checksum rules
Why A is correct
Cyclic control traffic depends on bounded and repeatable latency. An inline device that buffers and inspects packets adds variable delay and can cause missed cycles and faults. The other claims describe effects that do not occur.
