DCA · Question #135
A users attempts to set the system time from inside a Docker container are unsuccessful. Could this be blocking this operation? Solution: inter-process communication
The correct answer is B. No. Inter-process communication (IPC) isolation focuses on separating communication channels between processes and does not directly block system time modification.

Why each option
Inter-process communication (IPC) isolation focuses on separating communication channels between processes and does not directly block system time modification.
IPC isolation is designed to segregate communication resources between processes, not to control system-level operations such as modifying the host's system clock.
Inter-process communication (IPC) namespaces isolate system V IPC objects and POSIX message queues between containers. Blocking operations like setting the system time is not a function of IPC isolation but rather relates to security capabilities or privileged access.
