Question No : 8
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.A Juniper Mist Edge cluster in the corporate data center and another in the DM
C.A single WLAN template applied to the site containing three distinct SSIDs: 'Corporate', 'Guest', and 'IoT'.
D.Two Mist Tunnel objects: one pointing to the data center cluster and one pointing to the DMZ cluster.
E.A WxLAN policy to block traffic between the Corporate, Guest, and IoT VLANs.
F.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.

Question No : 9
When is it appropriate to manually set the channel and power for an AP instead of relying on RRM?

A.In all network deployments.
B.In a dynamic, high-density environment where conditions change frequently.
C.In a stable environment with a predictable RF landscape, such as a remote office with a single AP, to prevent unnecessary changes.
D.Never, RRM should always be used.

Question No : 10
A Juniper Mist Edge appliance is configured with Upstream Resource Monitoring to check the availability of the default gateway at 10.1.1.1. The monitoring is configured to use an ARP probe.
Upstream Resource Monitoring
-
Protocol: ARP
Destination Hostname / IP: 10.1.1.1
Source VLAN: 10

VLAN Interfaces

VLAN 10: 10.1.1.254/24
If the default gateway at 10.1.1.1 stops responding to ARP requests, what is the immediate impact on the Mist Edge appliance?

A.The Mist Edge appliance will reboot.
B.The tunnel termination services will become inactive to prevent traffic black-holing.
C.The Mist Edge will send an alert but continue to forward traffic.
D.The APs will automatically fail over to the secondary cluster, if one is configured.

B.Disable lower data rates (e.g., 1, 2, 5.5, 11 Mbps).
C.Enable only WPA3 security.
D.Ensure that lower data rates are enabled and supported.

Question No : 12
In a high-density lecture hall, an administrator observes that while the 5 GHz band is performing well, the 2.4 GHz band is heavily congested with co-channel interference. They want to reduce this interference without completely disabling the 2.4 GHz band, as some legacy devices rely on it.
Which Mist RRM feature would be the most appropriate solution?

A.Enable Geofencing with a high RSSI threshold.
B.Manually set all 2.4 GHz radios to use channel 6.
C.Enable "Auto-Cancellation" in the RF Template.
D.Set the 2.4 GHz channel width to 40 MHz.

Question No : 13
An administrator wants to use a single WLAN template for multiple sites. The corporate SSID is the same everywhere, but the guest SSID name needs to be unique for each site (e.g., "BranchA-Guest", "BranchB-Guest").
How can this be achieved using a single WLAN template?

A.It cannot be done; a separate WLAN template is required for each site.
B.In the WLAN template, create the guest WLAN and use a variable like `{{site_name}}-Guest` in the SSID field.
C.Create a Device Profile for each site and define the guest SSID name within the profile.
D.Use a WxLAN policy to dynamically change the SSID name based on the client's location.
