問題 #88
Which statement correctly describes the Juniper Mist Marvis Virtual Network Assistant (VNA)?
答案：C
解題說明：
Marvis is the Virtual Network Assistant within Juniper Mist that leverages AI/ML and natural language processing, allowing administrators to type conversational queries (such as "why are clients failing to connect at Site X") and receive actionable insights and troubleshooting guidance derived from the underlying AI engine.
問題 #89
Which two components make up a self-driving AI network? (Choose two.)
答案：B,D
解題說明：
A self-driving AI network is comprised of two foundational components: actions and telemetry. According to Juniper's own communications, "Marvis AI analyzes telemetry across the wired, wireless, WAN and data center domains, and creates automated workflows to simplify operations and lower costs. Agentic AI:
Accelerating self-driving operations." Telemetry provides real-time continuous data and metrics from the network, including client, device, and application health, enabling the AI engine to build a current, actionable state model. Actions refer to proactive, automated tasks performed by the AI, such as remediating misconfigured ports, resolving anomalies, optimizing performance, and self-healing operations-"Expanded Self-Driving Actions... the Marvis Actions dashboard now supports the autonomous remediation of more network issues." Human interface and support tickets are beneficial for management and support, but the core capabilities of a self-driving AI network are telemetry (data/observability) and actions (automation
/remediation).

問題 #90
How often does Marvis Minis execute automatic validations?
答案：D
解題說明：
Marvis Miniscontinuously validates the health of network services by performing synthetic tests at predefined intervals without requiring user intervention. These tests simulate real client interactions - such as authentication, DHCP, DNS, and application reachability - to detect network issues proactively.
According to theJuniper Mist Marvis Minis Technical Overview, the feature performs:
"Automated validations every hour to ensure wireless, wired, and WAN network services are operating as expected." Each validation cycle allows the Minis agent (running on Mist Access Points) to verify connectivity and performance parameters across key stages of the client experience. If any issues are detected, they are automatically surfaced in theMarvis Actions dashboardfor further analysis.
While administrators can trigger additional manual tests,automatic validations occur every hourby default across all enabled sites.
Therefore, the correct answer isB. Every hour.
