Question

A network administrator is Implementing a routing configuration change and enables routing debugs to track routing behavior during the change. The logging output on the terminal is interrupting the command typing process. Which two actions can the network administrator take to minimize the possibility of typing commands incorrectly? (Choose two.)

Options

  • AConfigure the logging synchronous global configuration command
  • BConfigure the logging delimiter feature
  • CConfigure the logging synchronous command under the vty
  • DPress the TAB key to reprint the command in a new line
  • Eincrease the number of lines on the screen using the terminal length command

Explanation

Explanation

When debug logging floods the terminal, two effective solutions are: logging synchronous under vty lines (C), which ensures that any log message interrupting your typing automatically reprints your partially-typed command on a new line, preventing confusion about what you've already entered; and pressing TAB (D), which completes or reprints your current command on a fresh line, allowing you to see exactly what you're typing without the noise of interleaved log messages.

Why the distractors are wrong:

  • A is close but incorrect - logging synchronous must be configured under the line (vty or console), not as a global configuration command, making C the valid choice.
  • B (logging delimiter) is not a standard IOS feature for this purpose and does not address terminal interruption.
  • E (terminal length) controls how many lines display before pausing output (like a "more" prompt), but does not prevent log messages from interrupting your typing.

Memory Tip

Think "Sync on the Line, TAB to Realign" - logging synchronous belongs under the line configuration (not global), and TAB is your quick keyboard shortcut to push your command to a clean line. If you see "global configuration" for logging synchronous, that's a trap!
