Question 3

A cloud-native application managed by CA APM is experiencing intermittent, significant performance degradations, causing user-facing latency spikes that do not consistently trigger pre-defined static alert thresholds. The engineering team is struggling to pinpoint the root cause due to the sporadic nature of the events and the dynamic scaling of underlying microservices. As the CA APM Administrator, how would you proactively adapt the monitoring strategy to effectively maintain visibility and diagnose these elusive issues while ensuring operational stability during this period of uncertainty?

Accepted Answer

Implement adaptive alerting based on anomaly detection and statistical deviation from baseline behavior, coupled with a focused effort to refine data collection granularity for suspected problematic microservices, and initiate cross-functional deep-dive sessions to collaboratively analyze emergent patterns.

Question 4

During a critical business period, the CA APM environment is experiencing intermittent, severe performance degradation across several key user-facing applications, attributed to an unforeseen surge in inbound data processing requests from an external partner integration. Initial investigations reveal no outright system failures or configuration errors, but rather a complex interplay of increased load and potentially suboptimal data ingestion patterns from the partner. The administrator must rapidly adapt the APM strategy to provide actionable insights and mitigate the immediate impact without disrupting ongoing business operations or introducing new performance issues. Which of the following approaches best exemplifies the administrator\'s required adaptability and problem-solving abilities in this ambiguous and high-pressure situation?

Accepted Answer

Temporarily reduce the data collection frequency for less critical application components to free up APM agent resources, while simultaneously creating custom dashboards to highlight the specific metrics related to the external partner integration and adjusting alert thresholds for key response time indicators to reflect the current operational context.

Question 5

A large enterprise is undertaking a phased migration of its critical business applications from on-premises data centers to a public cloud environment. The existing Application Performance Management (APM) solution, a mature on-premises platform, is slated for decommissioning.
