JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 14

You have a conference room with an open network port that is used by employees to connect to the network. You are concerned about rogue switches being connected to this port.
Which two features should you enable on your switch to limit access to this port? (Choose two.)

Answer options

• A. DHCP snooping
• B. dynamic ARP inspection
• C. MAC limiting
• D. 802.1X

Correct answer: C, D

Explanation

Enabling MAC limiting restricts the number of MAC addresses that can be learned on a switch port, preventing rogue devices from connecting. Implementing 802.1X provides port-based network access control, ensuring that only authenticated devices can access the network through that port, thus enhancing security.
