Which step in the router boot process searches for an IOS image to load into the router?
Click on the arrows to vote for the correct answerA. B. C. D.
The correct answer is C. Bootstrap.
When a router powers up, the first step it takes is to perform the Power-On Self-Test (POST). The POST checks the router's hardware to ensure that it is functioning correctly. If any hardware failures are detected, the router will not continue to boot up.
After the POST, the router will start the bootstrap process. The bootstrap is a small program stored in the router's ROM that is responsible for loading the IOS image from a specified location. The bootstrap will use a default location to look for the IOS image unless it is configured to search for the image in a specific location.
The bootstrap first looks for the IOS image in the router's flash memory. If the IOS image is not found in flash memory, the bootstrap will then look for the image in a TFTP server specified by the router's configuration. If the IOS image is found, the bootstrap loads it into the router's RAM.
If the router cannot find a valid IOS image, it will enter ROMMON mode (answer B). ROMMON is a mode in which the router is waiting for a command from the administrator to help it recover from a failed boot attempt.
Answer A (mini-IOS) is incorrect because mini-IOS is not a step in the router boot process. A mini-IOS is a backup IOS image that is stored in the router's flash memory. It is used as a backup in case the primary IOS image fails.
Answer D (POST) is incorrect because while the POST is the first step in the router boot process, it is not the step that searches for an IOS image to load into the router.
