Implementing Cisco Network Security (IINS, legacy) — Question 120

According to Cisco best practices, which three protocols should the default ACL allow on an access port to enable wired BYOD devices to supply valid credentials and connect to the network? (Choose three.)

Answer options

• A. BOOTP
• B. TFTP
• C. DNS
• D. MAB
• E. HTTP
• F. 802.1x

Correct answer: A, B, C

Explanation

The correct protocols A (BOOTP), B (TFTP), and C (DNS) are essential for enabling devices to obtain IP addresses and other network information, facilitating their connection to the network. Options D (MAB), E (HTTP), and F (802.1x) are not necessary for the initial authentication process for wired BYOD devices, making them less relevant in this context.
