問題 #151
Which two Mist UI options are available to receive notifications of Mist cloud status changes?
(Choose two.)
答案：B,C
解題說明：
Notification Options in Mist UI:
Mist provides several options for receiving notifications about Mist cloud status changes.
Available Notification Methods:
SNMP: Typically used for network management but not a primary method for Mist notifications.
RSS: Not commonly used for real-time notifications.
Slack: Mist can integrate with Slack to provide notifications directly to communication channels.
Email: Mist can send email notifications about cloud status changes.
問題 #152
What are three features of Juniper Mist? (Choose three.)
答案：B,C,D
解題說明：
Juniper Mist delivers Automatic Feature Updates, Wireless Assurance, and Asset Tracking as core platform features.
* Automatic feature updates: As part of its cloud architecture, Juniper Mist provides bi-weekly, hitless automatic updates for features and security, delivered seamlessly from the cloud without service interruption or manual intervention. Mist documentation states, "New features, security patches, and updates are automatically added on a bi-weekly basis without interruptions or service downtime. This dramatically simplifies and improves service operations for network IT administrators."
* Wireless Assurance: Wireless Assurance is Mist's flagship cloud service that leverages AI and machine learning to automate wireless network operations, delivering predictable, reliable, and measurable Wi- Fi experiences. It provides deep visibility into client states, sets service level expectations (SLEs), and uses Marvis actions and AI-driven recommendations to ensure root-cause identification and proactive troubleshooting-"Mist Wi-Fi Assurance is a cloud service based on machine learning (ML) and driven by Mist AI... designed for the smart device era."
* Asset tracking: Asset Visibility/Tracking uses vBLE technology and Wi-Fi to track and locate assets and IoT devices within an organization, integrating with Juniper Mist Cloud for real-time and historical analytics. According to the Asset Visibility datasheet: "Mist Asset Visibility is a cloud service that enables real-time tracking and historical location analytics of people, assets, and IoT devices." Controller firmware updates and perpetual AP licenses are not listed features of the Mist cloud architecture; Mist uses a cloud-based control plane and subscription-based licensing for its platform.

問題 #153
Your manager asks you to configure all your remote Juniper EX Series switches to use Dynamic Port Configuration. In this scenario, what are two criteria used for matching connected devices and assigning them their correct port and VLAN? (Choose two.)
答案：B,D
解題說明：
MAC address can be used to identify connected devices for Dynamic Port Configuration.
LLDP chassis ID provides device identity information, which is also used to match devices and assign the correct port and VLAN automatically.
問題 #154
Which two statements about webhooks and APIs are correct? (Choose two.)
答案：A,C
解題說明：
In theJuniper Mist Cloud architecture, bothwebhooksandAPIsare key interfaces for automation, integration, and data exchange with third-party systems. While they both facilitate communication between Mist and external applications, they operate inopposite directionsand serve distinct purposes.
According to theJuniper Mist API and Webhook Developer Guide:
* Webhooksarepush-based notificationsinitiated by the Juniper Mist Cloud. When specific events occur (such as device disconnection, client onboarding, or alert generation), Mist sends structured JSON payloads to a preconfigured external URL endpoint.
* APIs(Application Programming Interfaces) arepull-based querieswhere an external client polls the Mist Cloud to retrieve or update data (e.g., inventory, configuration, or metrics).
Additionally, the Mist Cloud enforcesrate limitson API calls to ensure platform stability and fair usage:
"API rate limits are applied on a per-organization basis to prevent excessive polling and to maintain consistent performance." In contrast, webhooks do not have a strict hourly quota because they are event-triggered rather than continuous requests.
Therefore:
* Ais correct - Webhooks push, APIs pull.
* Bis correct - There is an hourly API rate limit per organization.
OptionsCandDare incorrect because webhooks are event-based (not rate-limited hourly) and do not configure Mist objects directly-they only send notifications.

問題 #155
What happens to the captured data after a packet capture is stopped or completed?
答案：C
解題說明：
Thepacket capture featureinJuniper Mist Cloudallows administrators to remotely capture live network traffic from managed devices such as Access Points (APs) or switches for detailed troubleshooting.
According to theJuniper Mist Network Troubleshooting and Diagnostics Guide:
"Once a packet capture session is stopped or completed, the captured data is saved as a downloadable .pcap file that can be analyzed offline using tools such as Wireshark." This ensures administrators can inspect packet-level details for issues such as authentication failures, DHCP errors, or connectivity drops. The data is stored temporarily and made available through the Mist UI for download before automatic cleanup.
OptionsB,C, andDare incorrect because captured data is not stored permanently in the cloud, does not trigger automated alerts, and is not discarded immediately. The purpose is to make the data accessible foroffline inspection and analysis.
Therefore, the correct answer isA. It is saved as a downloadable capture file for offline inspection.
