When automating configuration templates in Juniper Mist using Python, which library would you use to parse and manage YAML files containing network configurations?
a. JSON
b. TensorFlow
c. PyYAML
d. Pandas
In a Juniper Mist environment, which programming approach would be best for developing a custom security alert system?
a. Using C++ for high-performance computing tasks
b. Employing Python with Juniper Mist APIs for flexibility and ease of use
c. Utilizing Ruby on Rails for web-based dashboard creation
d. Implementing PHP for server-side scripting
What is a primary function of Juniper Mist Access Assurance?
- A . Provides WAN optimization
- B . Manages switch PoE profiles
- C . Controls user access with 802.1X policies
- D . Automates BGP peer configuration
C
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.
A company is deploying Juniper Mist solutions across multiple branch offices. The key requirement is to maintain consistent network policies and to manage all network operations from a central location.
Which combination of solutions is most appropriate?
a. WAN Edge with Marvis VNA
b. Wireless and Wired Assurance
c. Routing Assurance and SD-WAN
d. Access Assurance and Marvis VNA
What is the function of the Apstra Intent Graph?
- A . Maps wireless client onboarding
- B . Represents the desired state of the data center fabric
- C . Logs all firewall rule updates
- D . Converts VRF to VLAN
B
Explanation:
The Intent Graph is a visual representation of how the data center is intended to operate, including
connectivity, protocols, and services. It helps track compliance to the intended network behavior.
Which key capability does Apstra provide to prevent human-induced errors?
- A . Real-time IP scanning
- B . Intent validation and continuous assurance
- C . Port mirroring
- D . VLAN pruning
B
Explanation:
Apstra’s closed-loop assurance continuously validates configurations against the intended design, reducing configuration errors caused by human missteps or misalignment.
Which feature of Routing Assurance helps ensure redundancy and SLA compliance?
- A . Route path visualization
- B . Ping test scripts
- C . Application-layer deep packet inspection
- D . DNSSEC verification
A
Explanation:
Routing Assurance visualizes route paths and detects issues like single points of failure or degraded performance, helping meet SLAs. It operates at the network layer, not application layer.
Which component enables Access Assurance to detect rogue devices?
- A . Spanning Tree Protocol
- B . Marvis anomaly detection
- C . MAC Authentication Bypass
- D . Device fingerprinting
D
Explanation:
Access Assurance uses device fingerprinting to identify known vs. unknown devices, allowing policies to be applied or alerts triggered for rogue detection. STP is a loop prevention protocol.
Which two benefits does Mist SD-WAN offer compared to traditional WAN? (Choose two.)
- A . Manual route updates
- B . AI-based path selection
- C . Secure vector routing
- D . Static policy enforcement
B, C
Explanation:
Mist SD-WAN leverages AI to make dynamic path decisions based on performance and uses Secure Vector Routing (SVR) for secure, scalable control. Manual updates and static policies are legacy approaches.
Which aspect of SD-WAN does Application-Aware Routing impact?
- A . Firewall logging
- B . DNS redirection
- C . Path selection based on app performance
- D . VRF segmentation
C
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.
