ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 15

Which statement about upgrading a cisco ios device with TFTP is True?

Answer options

• A. The Cisco IOS device must be on the same lan as the TFTP server
• B. The operation is performed in passive mode
• C. The operation is performed in an unencrypted format
• D. The operation is performed in active mode

Correct answer: A

Explanation

The correct answer is A because for a Cisco IOS device to successfully upgrade via TFTP, it must be on the same local area network as the TFTP server. Options B and D are incorrect as TFTP operates in a mode that does not strictly conform to passive or active definitions like FTP, and option C is misleading since, although TFTP is not encrypted, the phrasing of 'executed' does not accurately reflect the nature of TFTP operations.
