Question 12
What are two 802.11 MAC frame types? (Choose two.)
Correct Answer: A,C
Reference: https://howiwifi.com/2020/07/13/802-11-frame-types-and-formats/#:~:text=There%20are% 20three%20types%20of,the%20layer%203%2D7%20information According to the Lecture 4 - MAC Layer - Part 1 document, two 802.11 MAC frame types are: Control, which is used to coordinate access to the wireless medium and acknowledge successful transmissions. Management, which is used to establish and maintain associations between devices and perform functions such as authentication, scanning, and roaming.

Question 13
A helpdesk technician is unable to resolve an AP connectivity issue and decides to replace the faulty AP with a new one. The goal is to have the new AP adopt the exact same configuration as the old one, including its name, site assignment, and any device-level overrides, with minimal manual effort. What is the most efficient procedure in the Mist UI to accomplish this?
Correct Answer: B
Question 14
What is meant when a Marvis Action is shown as "AI Validated"?
An access point discovers switch information using which protocol?
Correct Answer: D
InJuniper Networks Mist AI Wireless, access points discover upstream switch and port information using Link Layer Discovery Protocol (LLDP). LLDP is an IEEE-standard, vendor-neutral Layer 2 discovery protocol designed specifically to allow network devices to advertise and learn information about directly connected neighbors. When a Juniper Mist AP connects to a wired switch, it uses LLDP to exchange information such as: * Switch hostname and chassis ID * Switch port identifier * VLAN details * Power over Ethernet (PoE) capabilities and power allocation This information is critical for Mist operations and visibility. It enables the Mist cloud to accurately display AP-to-switch mappings, identify theexact switch portan AP is connected to, validate PoE delivery, and assist with troubleshooting wired-side issues that impact wireless performance. LLDP data is also leveraged by Mist AI and Marvis to correlate wired and wireless events, improving root-cause analysis. The other options are incorrect for the following reasons: * CDP (Cisco Discovery Protocol)is a Cisco-proprietary protocol and is not used by Juniper Mist APs for switch discovery. * ARP (Address Resolution Protocol)resolves IP addresses to MAC addresses and does not provide device or port identity information. * SNMPis a management and monitoring protocol used by controllers or management systems, not by APs for neighbor discovery. Because LLDP is standards-based, lightweight, and designed for neighbor discovery, it is the correct and supported protocol used by Juniper Mist APs to learn switch information. Therefore, the correct answer isD. LLDP.
