Quiz: what a server exposes

Question 10 of 10

One correct answer

A package with a list of blocked addresses was upgraded, needrestart did not name the service, and it still lets the new address through. What finds who holds the old list?

sudo lsof +L1 — open files without a name.
dpkg-query -W — the version of the list package.
