Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 546

Which description of a default gateway is true?

Answer options

• A. It is a security feature that denies certain traffic.
• B. It is a device that receives IP packets that have no explicit next-hop in the routing table.
• C. It is a feature that translates between public and private addresses.
• D. It is a device that receives Layer 2 frames with an unknown destination address.

Correct answer: B

Explanation

The correct answer is B because a default gateway is responsible for forwarding IP packets that do not have a specified next-hop in the routing table, facilitating communication outside the local network. Option A describes a security feature that is not related to the function of a default gateway. Option C refers to Network Address Translation (NAT) rather than the role of a default gateway, and option D pertains to Layer 2 data handling, which is not the purpose of a default gateway.
