DCA · Question #132

Is this a type of Linux kernel namespace that provides container isolation? Solution: Network

The correct answer is B. No. While network resources are isolated using Linux kernel namespaces, "Network" itself is a descriptor of the resource, not the precise canonical name of a kernel namespace type.

Why each option

While network resources are isolated using Linux kernel namespaces, "Network" itself is a descriptor of the resource, not the precise canonical name of a kernel namespace type.

AYes

The precise name of the Linux kernel namespace responsible for network isolation is `net`, using the `CLONE_NEWNET` flag, rather than the general term "Network".

BNoCorrect

Although network isolation is achieved through `net` namespaces, the term "Network" as presented is not the canonical name of a specific Linux kernel namespace type; instead, it describes the isolated resource rather than the exact namespace identifier.
