- B. Apstra provides closed-loop automation based on intent
- C. Apstra uses VLANs only
- D. Traditional DCs use only wireless switches
正解：B
解説：
Unlike traditional systems that require manual provisioning and auditing, Apstra automates configuration, monitoring, and correction based on intent-defined policies and state validation.

- A. Provides cable diagnostics
- B. Detects DHCP server failures
- C. Suggests fixes for routing misconfigurations
- D. Assigns OSPF priorities
正解：C
解説：
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.
質問 # 33
Which metrics are monitored by SD-WAN to determine path performance?
- A. BGP AS path length
- B. Latency, jitter, and packet loss
- C. DNS TTL values
- D. CPU temperature
正解：B
解説：
SD-WAN solutions track link metrics such as latency, jitter, and packet loss to choose optimal paths for application traffic. These are critical for maintaining user experience.
質問 # 34
Routing Assurance allows integration with which of the following systems for path monitoring?
- A. ChatGPT API
- B. Telemetry platforms
- C. Syslog collectors
- D. SNMPv1 traps
正解：B
解説：
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.
質問 # 35
What is the main goal of Secure Vector Routing in Juniper SD-WAN?
- A. Prevent SD-WAN path loops
- B. Force VLAN translations
- C. Encrypt email headers
- D. Provide secure and scalable control plane
正解：D
解説：
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.
質問 # 36
What does Access Assurance dynamically assign upon successful authentication?
- A. Port speed
- B. IP route
- C. VLAN and Role
- D. Switch hostname
正解：C
解説：
Access Assurance dynamically assigns VLANs and user roles based on authentication results.
This enables network segmentation and access control tied to identity.
質問 # 37
What type of assurance does Marvis VNA offer in the data center environment?
- A. VLAN loop prevention
- B. Physical cabling fault detection
- C. Behavioral anomaly detection and recommendation
- D. App-layer DPI
正解：C
解説：
Marvis VNA in the data center uses AI to detect behavioral anomalies (e.g., sudden topology changes) and recommends corrective actions. It does not inspect app payloads or cabling directly.
質問 # 38
What does "policy intent verification" mean in Routing Assurance?
- A. Logging commands for firewall rules
- B. Checking for ARP table consistency
- C. Inspecting packet payloads
- D. Verifying that route paths match desired policies
正解：D
解説：
Routing Assurance verifies whether actual route paths match the intended policy configuration (intent). This helps ensure that traffic flows are following business-defined policies.
質問 # 39
Which dashboard allows viewing site-wide wireless health KPIs in Mist?
- A. Topology
- B. Site Performance
- C. SLE Overview
- D. Site Map
正解：C
解説：
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.
質問 # 40
What type of anomalies does Routing Assurance detect in BGP sessions?
- A. DNS lookup failures
- B. Web traffic spikes
- C. MAC address duplication
- D. Peer flaps and misroutes
正解：D
解説：
Routing Assurance detects BGP-related anomalies like frequent flapping, route leaks, and unexpected peer behaviors. It does not monitor DNS, web traffic, or MAC-related issues.
質問 # 41
Which two features are provided by Apstra intent-based analytics? (Choose two.)
- A. VLAN mirroring
- B. Intent-based policy rollback
- C. Predictive link failure detection
- D. Native email encryption
正解：B、C
解説：
Apstra includes analytics to predict issues like link failures and provides rollback features for policy changes that violate intent. It does not deal with email encryption or VLAN-specific diagnostics.
質問 # 42
What is the primary function of Apstra within Juniper's data center architecture?
- A. Manages PoE budgets across campuses
- B. Controls SD-WAN tunnels
- C. Enforces endpoint firewalls
- D. Provides AI-driven data center intent-based networking
正解：D
解説：
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.
質問 # 43
Which tool can be used to simulate the effect of a proposed change in Apstra?
- A. Cloud Telemetry Sandbox
- B. Change Control Simulation Engine
- C. Marvis CLI
- D. Mist Insights
正解：B
解説：
Apstra includes a Change Control Simulation Engine that allows administrators to preview the impact of network changes. This helps prevent configuration errors before deployment.
質問 # 44
Which platform integrates with Mist Access Assurance to manage authentication policies?
- A. AWS Lambda
- B. RADIUS server
- C. Azure Blob Storage
- D. ElasticSearch
正解：B
解説：
Mist Access Assurance integrates with a RADIUS server for identity authentication and policy enforcement. It supports 802.1X and MAC-based policies through the RADIUS protocol.
質問 # 45
What does the term "port bounce" refer to in Wired Assurance troubleshooting?
- A. Port receives DDoS
- B. Port is shut and enabled automatically
- C. Port loops traffic
- D. Port is overloaded
正解：B
解説：
A "port bounce" is the process of administratively disabling and re-enabling a port to recover from issues like stuck sessions or failed negotiation. It's a common troubleshooting method.
質問 # 46
Which two operations are automated by Apstra in the data center? (Choose two.)
- A. NAT traversal
- B. Intent rollback
- C. Underlay and overlay configuration
- D. Auto firmware updates of access points
正解：B、C
解説：
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.
質問 # 47
Which two routing protocols are monitored under Routing Assurance? (Choose two.)
- A. SMTP
- B. OSPF
- C. RIPv1
- D. BGP
正解：B、D
解説：
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.
