Which feature of Routing Assurance helps ensure redundancy and SLA compliance?
- A. Ping test scripts
- B. DNSSEC verification
- C. Route path visualization
- D. Application-layer deep packet inspection
Answer: C
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.
NEW QUESTION # 39
What is a key difference between Apstra and traditional data center management?
- A. Apstra provides closed-loop automation based on intent
- B. Apstra relies on manual provisioning
- C. Traditional DCs use only wireless switches
- D. Apstra uses VLANs only
Answer: A
Explanation:
Unlike traditional systems that require manual provisioning and auditing, Apstra automates configuration, monitoring, and correction based on intent-defined policies and state validation.
NEW QUESTION # 40
What problem does Apstra's rollback mechanism help solve?
- A. High CPU usage on switches
- B. DNS poisoning
- C. Policy violation due to misconfigurations
- D. Link-level jitter
Answer: C
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 # 41
Which component enables Access Assurance to detect rogue devices?
- A. Device fingerprinting
- B. MAC Authentication Bypass
- C. Spanning Tree Protocol
- D. Marvis anomaly detection
Answer: A
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.
NEW QUESTION # 42
Which SLE category is not part of Wireless Assurance by default?
- A. Coverage
- B. Roaming
- C. Throughput
- D. Gateway Latency
Answer: D
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.
