JNCIS-DC: Juniper Networks Certified Specialist – Data Center — Question 21

Your customer added an Apple TV in their conference room so that employees can easily share their screen. However, the Apple TV cannot be discovered by the employees’ devices.
Which two settings are causing the problem? (Choose two.)

Answer options

• A. MDNS
• B. Broadcast/Multicast
• C. Ignore Broadcast SSID Probe Requests
• D. ARP

Correct answer: A, D

Explanation

The correct answers are A and D. MDNS (Multicast DNS) is necessary for device discovery on local networks, and if it's disabled, the Apple TV won't be found. ARP (Address Resolution Protocol) is essential for IP address resolution; if it's not functioning properly, devices will struggle to communicate with the Apple TV, leading to discovery issues. Options B and C do not directly relate to the discovery process in this context.
