CUBE SNMP Monitoring Essential Elements
Short answer
BE SIP Calls Arrival Rate Per Second SIP Trunk Status
Question
Key Takeaways
The exam tests specific MIB objects available for CUBE; the common trap is confusing CLI-only status checks with SNMP-reportable metrics like arrival rates.
This question tests knowledge of Cisco Unified Border Element (CUBE) capabilities via SNMP. The community consensus identifies SIP Calls Arrival Rate Per Second and SIP Trunk Status as the essential monitoring elements.
Common mistake: Many candidates incorrectly select SIP Trunk Status (E), believing it is SNMP-monitored, whereas it is often only accessible via CLI or requires specific configuration not implied by 'currently available' standard SNMP monitoring in this context.
Expert Analysis
Why the Answer Is Correct
Cisco documentation indicates that CUBE supports SNMP monitoring for specific real-time metrics to allow network managers to track call volume and trunk health without CLI access. Specifically, the SIP Calls Arrival Rate Per Second (B) provides critical load information, while SIP Trunk Status (E) allows for immediate visibility into connectivity issues via standard SNMP traps or polling.
Why the Other Options Are Wrong
Real-Time SIP Trunk Utilization (A) and Historical SIP Trunk Utilization (D) are typically derived from NetFlow or syslog data rather than direct SNMP MIB objects in many standard deployments. SIP Calls Holding Time (C) is a statistical metric often aggregated over time and not always exposed as a real-time SNMP variable for immediate monitoring.
Community Comment Notes
Comment [1] references the official CUBE white paper which outlines management capabilities. Comment [4] highlights a key distinction: while some versions might support status, the exam context often treats 'SIP Trunk Status' as a primary SNMP feature in contrast to utilization stats which may require other protocols. However, the prevailing vote (BE) suggests B and E are the intended 'essential' pair for this specific exam version.

Exam Strategy
Focus on distinguishing between metrics available via SNMP versus those requiring NetFlow or CLI. For CUBE, prioritize knowing which call statistics (like arrival rates) and state indicators (trunk status) are natively exposed in the standard MIBs.
