Question 191 · 610 in bank
A network administrator installed a new VLAN to the network after a company added an additional floor to the office. Users are unable to obtain an IP address on the new VLAN, but ports on existing VLANs are working properly. Which of the following configurations should the administrator update?
Show answer
Answer: D
Explanation
IP helper directly addresses the VLAN-specific DHCP delivery issue. The administrator needs to update the router’s configuration for the new VLAN (e.g., ip helper-address ) to relay requests to the server. While a missing DHCP scope could also be an issue, the question asks for a “configuration to update,” and IP helper is a network-side fix tied to the VLAN addition. Answer: D. IP helper

A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?
Show answer
Answer: C
Explanation
Port security is a feature available on most network switches that allows you to control which devices can connect to a particular switch port based on MAC addresses. By enabling port security, the network administrator can restrict each port to only allow a specific set of MAC addresses, ensuring that only authorized devices can connect. If an unauthorized device tries to connect, the switch can take actions such as shutting down the port, dropping the traffic, or sending an alert.
