Which of the following statements is true about Windows containers isolation modes?

• A. Process Isolation
• B. Shared Isolation
• C. Virtualization Isolation
• D. Network Isolation

Answer: (A)

Windows containers use OS-level virtualization to isolate workloads, with different modes that trade off isolation strength against performance. The standard process isolation mode runs containers in the same host kernel but keeps them separate in terms of processes, file system view, and registry, using Windows security boundaries and namespace mechanisms. This provides efficient performance and compatibility for Windows apps, while still keeping each container’s processes from interfering with the host or other containers. There isn’t a recognized “shared isolation” mode in Windows containers, and “virtualization isolation” isn’t the standard term for the main container isolation modes (the stronger option is Hyper-V isolation, which runs containers in lightweight VMs with separate kernels). Network isolation pertains to networking controls rather than a distinct isolation mode. So process isolation is the true statement among the options provided.
