What happens if Access Assurance fails to authenticate a client?
- A . Client is always disconnected
- B . Client is given full access by default
- C . Guest fallback policy can be applied
- D . Static IP is assigned
C
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.
Which two services are part of Juniper’s Routing Assurance offering? (Choose two.)
- A . Route simulation
- B . Wi-Fi onboarding
- C . Peer state monitoring
- D . Switch stacking
A, C
Explanation:
Routing Assurance includes features like route simulation for intent verification and peer state monitoring for dynamic protocols. Wi-Fi and stacking are not its primary domains.
Which data type is used to define policy in Access Assurance?
- A . ASN
- B . User identity and role
- C . TCP port numbers
- D . VLAN priority bits
B
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.
Which two roles does Marvis play in Wireless Assurance? (Choose two.)
- A . Chat-based interface for queries
- B . L2/L3 policy orchestration
- C . Suggests SLE optimization
- D . Configures switch stack IDs
A, C
Explanation:
Marvis acts as a conversational AI to respond to IT queries and suggest optimizations, especially for SLEs. It doesn’t configure switches or create routing policies directly.
What problem does Apstra’s rollback mechanism help solve?
- A . DNS poisoning
- B . Policy violation due to misconfigurations
- C . High CPU usage on switches
- D . Link-level jitter
B
Explanation:
Apstra supports rollback to a previously known good state if a configuration causes an intent violation.
This helps quickly restore network compliance and availability.
What is the purpose of assigning switch profiles in Wired Assurance?
- A . To enforce IPS policies
- B . To manage routing tables
- C . To apply standardized port configs
- D . To extend VLANs across buildings
C
Explanation:
Switch profiles are used to apply consistent port configurations across similar switch models or roles.
They ensure uniform behavior, which simplifies operations and provisioning.
Which component of Routing Assurance validates configuration consistency across routers?
- A . Marvis Edge Engine
- B . EVPN Instance Validator
- C . Routing Policy Checker
- D . Configuration Drift Detection
D
Explanation:
Routing Assurance detects configuration drifts across routing devices and compares intended vs. running configurations to ensure consistency. It proactively prevents misconfiguration issues.
Which Mist component enables user-level visibility across wired and wireless connections?
- A . Marvis VNA
- B . Mist Edge
- C . Wired Assurance
- D . Client Health SLE
D
Explanation:
The Client Health Service Level Expectation (SLE) provides unified visibility for wired and wireless experiences. It measures onboarding time, throughput, and other KPIs to help ensure consistent client connectivity.
How can a network engineer automate the process of adjusting QoS settings based on traffic patterns using Juniper Mist APIs?
a. Write a Python script that adjusts QoS settings in real-time based on traffic analytics data.
b. Use manual CLI commands periodically to update QoS settings.
c. Develop a static website to display traffic patterns.
d. Employ a machine learning model in MATLAB to predict traffic.
Which Mist solution provides port-level insights for connected wired clients?
- A . Access Assurance
- B . Wired Assurance
- C . Secure Edge
- D . Port Authentication Manager
B
Explanation:
Wired Assurance delivers real-time port-level analytics for wired clients, allowing visibility into traffic, errors, and power usage. It is not involved in access control or security.
