NEW QUESTION # 43
Which data type is used to define policy in Access Assurance?
- A. TCP port numbers
- B. VLAN priority bits
- C. ASN
- D. User identity and role
Answer: D
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 # 44
What functionality does Marvis provide for Routing Assurance?
- A. Detects DHCP server failures
- B. Assigns OSPF priorities
- C. Suggests fixes for routing misconfigurations
- D. Provides cable diagnostics
Answer: C
Explanation:
Marvis can interpret routing telemetry data and offer suggestions to resolve misconfigurations, especially for BGP or OSPF. It does not handle physical layer diagnostics or DHCP monitoring.
NEW QUESTION # 45
Which two Service Level Expectations (SLEs) are part of Wireless Assurance? (Choose two.)
- A. Roaming success
- B. WAN latency
- C. Throughput
- D. BGP convergence
Answer: A,C
Explanation:
Wireless Assurance includes SLEs like roaming and throughput to monitor wireless experience.
WAN latency and BGP convergence relate more to WAN and routing functions, not Wi-Fi health.
NEW QUESTION # 46
What problem does Apstra's rollback mechanism help solve?
- A. Link-level jitter
- B. Policy violation due to misconfigurations
- C. DNS poisoning
- D. High CPU usage on switches
Answer: 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.
NEW QUESTION # 47
Which Mist solution provides port-level insights for connected wired clients?
- A. Port Authentication Manager
- B. Access Assurance
- C. Wired Assurance
- D. Secure Edge
Answer: C
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.
NEW QUESTION # 48
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 # 49
Which aspect of SD-WAN does Application-Aware Routing impact?
- A. DNS redirection
- B. VRF segmentation
- C. Path selection based on app performance
- D. Firewall logging
Answer: 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.
NEW QUESTION # 50
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. Employ a machine learning model in MATLAB to predict traffic.
- C. Use manual CLI commands periodically to update QoS settings.
- D. Develop a static website to display traffic patterns.
Answer: A
NEW QUESTION # 51
Which SLE category is not part of Wireless Assurance by default?
- A. Coverage
- B. Gateway Latency
- C. Throughput
- D. Roaming
Answer: B
Explanation:
Gateway Latency is typically not included in Wireless Assurance's default SLEs, which focus more on Wi-Fi-specific metrics like coverage, onboarding, throughput, and roaming.
NEW QUESTION # 52
What is the function of Wireless Assurance onboarding SLE?
- A. To monitor RF interference
- B. To report PoE consumption
- C. To measure software update time
- D. To assess client authentication time
Answer: D
Explanation:
The onboarding SLE tracks how quickly and successfully clients connect to the network, including DNS, DHCP, and authentication stages. It ensures a smooth initial experience for users.
NEW QUESTION # 53
What is the main goal of Secure Vector Routing in Juniper SD-WAN?
- A. Provide secure and scalable control plane
- B. Encrypt email headers
- C. Force VLAN translations
- D. Prevent SD-WAN path loops
Answer: A
Explanation:
Secure Vector Routing (SVR) provides a secure, efficient, and scalable control and data plane mechanism between WAN Edge devices. It replaces legacy MPLS or static VPN methods.
NEW QUESTION # 54
Which data does Wireless Assurance collect for anomaly detection?
- A. RF signal metrics
- B. DHCP and DNS stats
- C. Switch port errors
