In capacity planning exercises, what tools assist in identifying processes of interest from other processes? (Select TWO correct answers.)

The `acpid` daemon handles ACPI events and is not a general-purpose command-line tool for identifying and analyzing other processes.

The `lsof` command lists all open files and network connections by processes, which helps in identifying what resources a specific process is using and thus distinguishing it from other processes.

The `pstree` command displays running processes as a tree, showing parent-child relationships, which is highly useful for identifying processes belonging to a particular application or service group, making them processes of interest.

The `w` command shows who is logged on and what they are doing, providing user activity information but not detailed process identification relevant for distinguishing processes of interest in capacity planning.
