You need to completely reboot the Operating System after making which of the following changes on the Security Gateway? (i.e. the command cprestart is not sufficient.) 1. Adding a hot-swappable NIC…

The answer is A, options 2 and 3 only. Think of cprestart like restarting just the engine of your car while the chassis, wheels, and frame stay exactly as they are. That works fine for most tune-ups, but if you are swapping out the entire drivetrain, meaning installing or uninstalling something as deep as the R75 Power/UTM package, you are touching kernel modules and low-level OS components that the running system cannot safely reload on the fly. That is why both actions require a full reboot, not just a service restart. The other options do not reach that deep: a hot-swappable NIC is designed by definition to be recognized without rebooting, SIC re-establishment is purely a certificate and communication handshake at the Check Point service layer, and adjusting the maximum connections is a configuration value that Check Point reads when its processes restart, so cprestart covers it just fine.

Installing or uninstalling the R75 Power/UTM package requires a full OS reboot because those operations modify kernel modules and core components that cprestart simply cannot reload on the fly. Re-establishing SIC and changing max connections are both handled at the process level, so cprestart covers those just fine.

Saw this exact trap on my attempt, fell for D before realizing SIC and connections never need full reboot.
