CIS Performance Optimization & Monitoring 2

Question 1

Which type of testing is specifically designed to evaluate how a system performs under expected and peak load conditions before go-live?

Accepted Answer

Load and stress testing

Answer

Load and stress testing simulates expected and peak user volumes to identify bottlenecks and confirm the system can handle real-world demand.

Question 2

A CIS implementation reveals that nightly batch jobs are running longer than expected and impacting morning user performance. What is the BEST remediation approach?

Accepted Answer

Reschedule batch jobs during off-peak hours and optimize their execution logic

Answer

Rescheduling batch jobs to off-peak windows and optimizing their logic reduces resource contention and protects daytime user experience.

Question 3

What does 'caching' primarily accomplish in the context of system performance optimization?

Accepted Answer

It stores frequently accessed data in fast-access memory to reduce repetitive processing

Answer

Caching reduces the need to repeatedly fetch or compute the same data, significantly improving response times for frequently accessed information.

Question 4

Which monitoring practice helps a CIS professional detect memory leaks in a production application?

Accepted Answer

Tracking memory utilization trends over time and alerting when usage climbs without returning to baseline

Answer

A memory leak causes consumption to rise continuously without releasing resources; trend monitoring with alerts catches this pattern before it causes system failure.

Question 5

A client reports that their CRM system slows down at month-end when finance runs large reports. Which optimization strategy is most appropriate?

Accepted Answer

Schedule finance reports to run during off-hours or provide a dedicated reporting environment

Answer

Isolating resource-intensive reports to off-hours or a dedicated environment prevents them from degrading performance for concurrent operational users.
