Which Juniper Mist service enforces policy across both wired and wireless networks based on user identity?
- A. Mist Edge Fabric
- B. Routing Assurance
- C. Marvis VNA
- D. Access Assurance
Answer: D

Routing Assurance allows integration with which of the following systems for path monitoring?
- A. Telemetry platforms
- B. Syslog collectors
- C. ChatGPT API
- D. SNMPv1 traps
Answer: A
Explanation:
Routing Assurance integrates with telemetry platforms to gather real-time data for route validation, anomaly detection, and SLA monitoring. SNMPv1 and Syslog provide basic monitoring but are not primary.
NEW QUESTION # 45
What is an effective scripting method to automate the resolution of common network issues identified during Day 2 operations in a Juniper Mist environment?
- A. Setting up an Excel macro to log network issues.
- B. Implementing a Ruby script for database maintenance.
- C. Creating a batch file to restart servers daily.
- D. Using Python scripts integrated with Mist APIs to apply fixes automatically.
Answer: D
NEW QUESTION # 46
What happens if Access Assurance fails to authenticate a client?
- A. Static IP is assigned
- B. Client is always disconnected
- C. Client is given full access by default
- D. Guest fallback policy can be applied
Answer: D
Explanation:
If Access Assurance fails to authenticate a client, it can apply a fallback policy (e.g., limited guest access) based on predefined rules. This ensures continuity with restricted access.
NEW QUESTION # 47
Which data type is used to define policy in Access Assurance?
- A. ASN
- B. TCP port numbers
- C. User identity and role
- D. VLAN priority bits
Answer: C
Explanation:
Policies in Access Assurance are defined based on user identity and role, allowing dynamic segmentation.
This enables context-aware network access enforcement for users or devices.
NEW QUESTION # 48
Which aspect of SD-WAN does Application-Aware Routing impact?
- A. DNS redirection
- B. Firewall logging
- C. VRF segmentation
- D. Path selection based on app performance
Answer: D
Explanation:
Application-Aware Routing (AAR) dynamically routes application traffic based on real-time link performance (jitter, latency, loss). It ensures critical apps use the best path.
NEW QUESTION # 49
What is the role of Mist Edge in Access Assurance?
- A. Extends policy enforcement to campus network
- B. Hosts the routing table
- C. Acts as the AAA server
- D. Performs MAC learning
Answer: A
Explanation:
Mist Edge acts as a policy enforcement point in distributed enterprise networks, bringing Mist cloud policies to the wired and wireless edge. It doesn't host routing or perform AAA directly.
NEW QUESTION # 50
Which two routing protocols are monitored under Routing Assurance? (Choose two.)
- A. OSPF
- B. RIPv1
- C. BGP
- D. SMTP
Answer: A,C
Explanation:
Routing Assurance monitors dynamic routing protocols like OSPF and BGP for health, topology changes, and SLA violations. SMTP is a mail protocol and RIPv1 is outdated.
NEW QUESTION # 51
What is a primary function of Juniper Mist Access Assurance?
- A. Controls user access with 802.1X policies
- B. Provides WAN optimization
- C. Manages switch PoE profiles
- D. Automates BGP peer configuration
Answer: A
Explanation:
Access Assurance provides identity-based access control using policies such as 802.1X, MAC authentication, and guest access. It does not handle WAN optimization or BGP configuration.
NEW QUESTION # 52
Which dashboard allows viewing site-wide wireless health KPIs in Mist?
- A. SLE Overview
- B. Site Map
- C. Site Performance
- D. Topology
Answer: A
Explanation:
The SLE Overview dashboard aggregates key metrics across the wireless infrastructure, such as onboarding time, throughput, and signal quality. It helps visualize client experience at a site level.
