NEW QUESTION # 25
What is a primary function of Juniper Mist Access Assurance?
- A. Provides WAN optimization
- B. Automates BGP peer configuration
- C. Manages switch PoE profiles
- D. Controls user access with 802.1X policies
Answer: D
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 # 26
Which SLE metric might be used in Access Assurance to evaluate onboarding time?
- A. Number of BGP AS paths
- B. TCP retransmissions
- C. Time to first DHCP lease
- D. Route convergence
Answer: C
Explanation:
Access Assurance evaluates user onboarding using metrics like DHCP success, authentication time, and role assignment delays. Routing metrics like AS paths or TCP retransmissions are unrelated.
NEW QUESTION # 27
What is the role of Mist Edge in Access Assurance?
- A. Extends policy enforcement to campus network
- B. Acts as the AAA server
- C. Performs MAC learning
- D. Hosts the routing table
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 # 28
Which dashboard allows viewing site-wide wireless health KPIs in Mist?
- A. Site Map
- B. Site Performance
- C. SLE Overview
- D. Topology
Answer: C
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.
NEW QUESTION # 29
Which topology model does Apstra typically deploy in a data center?
- A. Hub-and-Spoke
- B. Ring topology
- C. EVPN-VXLAN Clos fabric
- D. Full Mesh Layer 3 VPN
Answer: C
Explanation:
Apstra supports EVPN-VXLAN in a Clos (leaf-spine) fabric as a common data center architecture.
It enables scalability, segmentation, and consistent policy enforcement across the fabric.
NEW QUESTION # 30
What is a key feature of Juniper Mist Wired Assurance?
- A. AI-driven switch insights
- B. Firewall rule orchestration
- C. Dynamic VLAN assignment
- D. Zero Trust micro-segmentation
Answer: A
Explanation:
Wired Assurance offers AI-driven visibility into switch health, port performance, and client-level experience. This enables faster root cause analysis. It does not manage firewall rules or micro- segmentation.
NEW QUESTION # 31
How can a network engineer automate the process of adjusting QoS settings based on traffic patterns using Juniper Mist APIs?
- A. Develop a static website to display traffic patterns.
- B. Employ a machine learning model in MATLAB to predict traffic.
- C. Use manual CLI commands periodically to update QoS settings.
- D. Write a Python script that adjusts QoS settings in real-time based on traffic analytics data.
Answer: D
NEW QUESTION # 32
In Juniper Mist solutions, what role does RADIUS play?
- A. Wireless client authentication
- B. Data encryption and security
- C. Traffic load balancing
- D. Routing protocol configuration
Answer: A
NEW QUESTION # 33
What does Marvis VNA for Data Center help visualize and monitor?
- A. VPN tunnels
- B. L7 application logs
- C. User onboarding flows
- D. Data center fabric anomalies
Answer: D
Explanation:
Marvis VNA in the data center context detects anomalies in fabric operations, such as misconfigured links, traffic bottlenecks, or underlay/overlay issues. It doesn't handle application or VPN monitoring.
NEW QUESTION # 34
Which two operations are automated by Apstra in the data center? (Choose two.)
- A. Auto firmware updates of access points
- B. Intent rollback
- C. Underlay and overlay configuration
- D. NAT traversal
Answer: B,C
Explanation:
Apstra automates both the configuration of underlay/overlay networking and rollback in case of a policy violation. It does not manage AP firmware or NAT-specific functions.
NEW QUESTION # 35
Which Mist tool would help visualize switch-level anomalies across time?
- A. Port Inspector
- B. Device Inventory
- C. Marvis Dashboard
- D. Anomaly Timeline
Answer: D
Explanation:
The Anomaly Timeline provides a historical view of abnormalities on switches, helping administrators track trends and identify recurring issues. Port Inspector offers real-time snapshots instead.
NEW QUESTION # 36
Which data type is used to define policy in Access Assurance?
- A. VLAN priority bits
- B. User identity and role
- C. ASN
- D. TCP port numbers
Answer: 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.
NEW QUESTION # 37
What problem does Apstra's rollback mechanism help solve?
- A. High CPU usage on switches
- B. Link-level jitter
- C. DNS poisoning
- D. Policy violation due to misconfigurations
Answer: D
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.
NEW QUESTION # 38
What is the primary function of Apstra within Juniper's data center architecture?
- A. Provides AI-driven data center intent-based networking
- B. Enforces endpoint firewalls
- C. Controls SD-WAN tunnels
- D. Manages PoE budgets across campuses
Answer: A
Explanation:
Apstra is Juniper's intent-based networking platform for data centers. It abstracts the desired state (intent) and ensures the infrastructure behaves accordingly, with continuous validation and closed-loop automation.
NEW QUESTION # 39
Which Mist component enables user-level visibility across wired and wireless connections?
- A. Wired Assurance
- B. Marvis VNA
- C. Mist Edge
- D. Client Health SLE
Answer: 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.
NEW QUESTION # 40
Routing Assurance allows integration with which of the following systems for path monitoring?
- A. SNMPv1 traps
- B. ChatGPT API
- C. Syslog collectors
- D. Telemetry platforms
Answer: D
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.
