Avaya Communication Server 1000 for Avaya Aura Maintenance Exam Free Practice Test — 30 Questions

Question 1

During a routine performance review of an Avaya Communication Server 1000 (ACS 1000) deployment, the network operations team observes a pattern of intermittent degradation in voice quality for a specific segment of users. These issues manifest as choppy audio and dropped calls, occurring most frequently during peak business hours. Initial hardware diagnostics on the Media Gateways and the Call Processing Server (CPS) show no critical alarms or hardware failures. However, network monitoring tools indicate transient spikes in jitter and packet loss on the inter-switch links connecting the CPS, which hosts the Media Gateway Controller (MGC) functionality, to the affected Media Gateways (MGs). The team suspects a resource contention or scheduling issue within the MGC/CPS rather than a network infrastructure failure. Which of the following diagnostic approaches would most effectively pinpoint the root cause of these intermittent voice quality issues, considering the potential for complex software interactions and resource management within the ACS 1000?

Accepted Answer

Analyze real-time MGC/CPS process scheduling priorities and resource utilization (CPU, memory) during periods of reported voice degradation, correlating these metrics with network QoS parameters and recent configuration changes.

Question 2

During a scheduled maintenance window for the Avaya Aura platform, a senior network engineer observes that the Avaya Communication Server 1000 (CS 1000) is exhibiting unpredictable behavior, leading to dropped calls and delayed call routing for a segment of users.
