CCNA: Cisco Certified Network Associate — Question 838

Which command must be entered so that the default gateway is automatically distributed when DHCP is configured on a router?

Answer options

• A. dns-server
• B. default-router
• C. ip helper-address
• D. default-gateway

Correct answer: B

Explanation

The correct answer is B, 'default-router', as this command is used in DHCP configuration to specify the default gateway that clients should use. Options A and C are related to DNS server configuration and helper address functionality, respectively, while option D refers to a command used on interfaces, not in DHCP configuration.
