You want to view an existing multiple-instance element's configuration. What step should you perform after you go to the correct branch of the configuration tree?

Question

Options

• ASelect the element and then issue the show command.
• BType show <element name>.
• CType show ? and select from the displayed list.
• DType is -a.
• EEnter the name of the element and then issue the show command.

Explanation

E is correct. In hierarchical CLI environments like Juniper Junos, multiple-instance elements (e.g., routing instances, interfaces) require you to first enter the specific named instance by typing its name - which moves your context into that instance's level - and then issue show to display its configuration.

Why the others are wrong:

• A says to "select" the element, which implies a GUI interaction; CLI navigation requires typing, not selecting.
• B (show <element name>) is the syntax used from the parent branch, not after you've already navigated to the correct branch - it conflates two separate steps.
• C (show ?) displays available subcommands or help, not the element's actual configuration.
• D (ls -a) is a Unix/Linux shell command for listing files; it has no function in a network device configuration CLI.

Memory tip: Think of it as a two-step "enter then inspect" pattern - you must identify the instance (enter its name) before you can interrogate it (show). The name gets you in, show lets you look around.
