質問 # 99
A large enterprise is deploying a campus-wide wireless network using Mist. They need to provide a secure corporate network for employees and a completely separate, tunneled network for guest traffic that terminates in a DMZ. They also need to provide a dedicated, tunneled network for IoT devices. All of these services must be available from a single set of APs. Which Mist components and policies are required to create this multi-service, segmented network? (Select all that apply.)
- A. A separate physical AP for each network type (Corporate, Guest, IoT).
- B. Two Mist Tunnel objects: one pointing to the data center cluster and one pointing to the DMZ cluster.
- C. A configuration where the 'Corporate' and 'IoT' WLANs are mapped to the data center tunnel, and the 'Guest' WLAN is mapped to the DMZ tunnel.
- D. A WxLAN policy to block traffic between the Corporate, Guest, and IoT VLANs.
- E. A Juniper Mist Edge cluster in the corporate data center and another in the DMZ.
- F. A single WLAN template applied to the site containing three distinct SSIDs: 'Corporate', 'Guest', and 'IoT'.
正解：B、C、E、F
質問 # 100
A user reports being unable to connect to the corporate WLAN. Marvis Actions identifies the root cause as "Authorization Failure".
What is the most likely reason for this failure?
- A. The AP is offline.
- B. The RADIUS server is rejecting the user's credentials.
- C. The DHCP server has no available IP addresses.
- D. The client entered the wrong password (PSK).
正解：B
質問 # 101
