Last updated on Oct 22,2026- Exam Code: JN0-452
- Exam Name: Juniper Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless)
- Certification Provider: Juniper
- Latest update: Oct 22,2026
A Mist AP is running Marvis Minis. One test shows that DNS lookup fails, and the portal page doesn’t load.
What is most likely true?
- A . The client SNR is too low
- B . The AP needs reboot
- C . The user password is incorrect
- D . The captive portal or DNS server is misconfigured
D
Explanation:
Marvis Minis simulate client connections; failure in DNS and portal page access indicates issues in DNS settings or captive portal configuration.
Which of the following is a recommended AP spacing for accurate vBLE triangulation in indoor deployments?
- A . 10 meters or less
- B . 20 meters or more
- C . Exact center of each room
- D . Random to reduce interference
A
Explanation:
For accurate directional triangulation using Mist vBLE, it is recommended to space APs ≤10 meters apart.
Which of the following is true about Marvis Minis?
- A . They run virtual test clients directly on Mist APs
- B . They require an external Raspberry Pi or client simulator
- C . They depend on SNMP to run
- D . They only test 2.4 GHz SSIDs
A
Explanation:
Marvis Minis are built-in virtual test clients that run natively on Mist APs, requiring no external hardware.
After modifying a network template, an admin wants to ensure the updates apply across all APs automatically.
Which Mist feature enables this process?
- A . Config Auto-Sync
- B . Manual CLI Commit
- C . SNMP Config Push
- D . VLAN Broadcast Mapping
A
Explanation:
Mist’s Config Auto-Sync pushes template or site changes automatically to all affected APs, ensuring consistency without manual CLI actions.
Which Mist WLAN access control option allows each user to log in with a unique username and password?
- A . WPA2-Personal (PSK)
- B . WPA2-Enterprise (802.1X with RADIUS)
- C . MAC-based control
- D . OWE (Opportunistic Wireless Encryption)
B
Explanation:
WPA2-Enterprise uses 802.1X and a RADIUS server to provide per-user authentication with individual credentials, ideal for enterprises.
An IT team at a university is trying to resolve complaints from students who say it takes too long to connect to Wi-Fi. The admin checks the Mist dashboard and finds that the **Time to Connect SLE** is consistently above 4 seconds.
Which tool or capability should they use to identify the exact failure step in the client process?
- A . AP Health Metrics
- B . RRM Power Analysis
- C . Client Journey Timeline
- D . DHCP Server Logs
C
Explanation:
The Client Journey Timeline allows admins to trace each step in a client’s connection attempt―association, authentication, DHCP, DNS―and see where delays occur. It’s the most efficient way to troubleshoot SLE issues like long connection times.
What is the maximum theoretical speed supported by IEEE 802.11ac (Wi-Fi 5)?
- A . 1.3 Gbps or more
- B . 600 Mbps
- C . 11 Mbps
- D . 10 Gbps
A
Explanation:
What is the purpose of Mist’s Client Journey Timeline feature?
- A . Display system logs of controller uplink status
- B . Show step-by-step logs of client connection events (association, auth, DHCP, etc.)
- C . Monitor Wi-Fi security compliance reports
- D . Control SSID broadcast timers
B
Explanation:
Mist’s Client Journey Timeline shows the client’s full connection path: association, authentication, DHCP, DNS, and SLE metrics. It’s ideal for troubleshooting.
A company wants to provide access to both employees and contractors through the same SSID. However, employees should be on VLAN 10 with access to internal resources, and contractors should be isolated on VLAN 20.
Which Mist feature enables this behavior?
- A . Captive Portal with sponsor approval
- B . Marvis AI Insights
- C . WxLAN with identity-based VLAN assignment
- D . MAC filtering on SSID
C
Explanation:
WxLAN allows Mist to apply policy-based VLAN assignments based on user role or authentication, even when users connect to the same SSID.
In the Mist organization hierarchy, what is the primary purpose of the “Site” level?
- A . Create API access tokens
- B . Monitor the entire organization’s traffic
- C . Represent a specific physical location with its own APs and settings
- D . Manage global templates and user roles
C
Explanation:
Each “Site” in Mist represents a physical location (e.g., office, store, campus) and can have its own APs, VLANs, and configurations.
