A network printer reachable at ipp://printer.example.com/ipp/print must be added to CUPS as a queue named laser, ready to accept and print jobs at once. Which command creates it?
LPIC-1 Exam 102-500, objective 108. Essential system services medium
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

The options
Correct lpadmin -p laser -E -v ipp://printer.example.com/ipp/print -m everywhere
Correct. lpadmin creates or modifies a destination: -p names the queue, -v gives the device URI, -m selects the model or driver and -E, given after -p, both enables the queue and sets it to accept jobs.
Not correct lpinfo -p laser -v ipp://printer.example.com/ipp/print
Wrong tool. lpinfo only reports what is available: lpinfo -v lists device URIs CUPS can see and lpinfo -m lists installable models. It creates nothing.
Not correct lpoptions -p laser -v ipp://printer.example.com/ipp/print
Wrong tool. lpoptions sets default job options for an existing destination, such as media size or duplexing, and with -d sets the user's default destination. It cannot define a queue or its device URI.
Not correct lpstat -p laser -v ipp://printer.example.com/ipp/print
Wrong. lpstat is purely a status reporter; -p shows printers and their state and -v shows the device URI of existing destinations. It takes no configuration input.
Why
lpadmin is the administrative command for CUPS destinations and it writes the resulting definition into /etc/cups/printers.conf, with the queue's PPD stored under /etc/cups/ppd/. Note that -E has two meanings depending on position: before -p it requests an encrypted connection to the server, after -p it enables the destination and makes it accept jobs. Without -E the queue exists but stays idle or rejects submissions.
