Exam 200-301 Question id=5350 Network Fundamentals

What is the default sequence in which a router searches for the Internetwork Operating System (IOS) image upon power on?

A. TFTP, Flash, ROM
B. ROM, Flash, TFTP
C. Flash, TFTP, ROM
D. Flash, TFTP, NVRAM
E. NVRAM, Flash, TFTP

The default sequence in which a router searches for the IOS image is in Flash memory, on a Trivial File Transfer Protocol (TFTP) server, and in read-only memory (ROM). The router will first search for the IOS image in the Flash memory. If there is no image in the Flash, the router will try to contact a TFTP server. If the router cannot find the IOS image on the TFTP server, it will load a limited version from the ROM.

The sequence that begins with TFTP and the sequence that begins with ROM are both incorrect sequences because the router will begin searching for the IOS image in Flash memory.

The sequences that include Non-volatile random access memory (NVRAM) are both incorrect because a router does not store the IOS image in NVRAM. The startup configuration is stored in NVRAM
