CIS Performance Optimization & Monitoring 1 — Questions and Answers
Question 1: Which metric is most commonly used to measure the overall health and responsiveness of a newly implemented system during the post-go-live period?
- Lines of code deployed
- Mean Time to Respond (MTTR) and system uptime percentage (Correct answer)
- Number of open change requests
- Total number of user accounts created
Correct answer: Mean Time to Respond (MTTR) and system uptime percentage
MTTR and uptime percentage directly reflect how quickly issues are resolved and how reliably the system is available, making them key health indicators post-go-live.
Question 2: A CIS professional notices that database query response times have increased significantly after a large data import. What is the BEST first step to address this?
- Restart the database server immediately
- Analyze query execution plans and check for missing indexes (Correct answer)
- Increase the number of licensed users
- Roll back the data import entirely
Correct answer: Analyze query execution plans and check for missing indexes
Reviewing query execution plans and identifying missing indexes addresses the root cause of slow queries without disrupting system availability.
Question 3: Which approach best describes 'baseline performance benchmarking' in a system implementation context?
- Measuring system performance only after users report problems
- Documenting expected system performance metrics before go-live to compare against post-implementation results (Correct answer)
- Running the system at maximum load for 24 hours before launch
- Allowing the vendor to define all performance targets independently
Correct answer: Documenting expected system performance metrics before go-live to compare against post-implementation results
Baseline benchmarking establishes pre-go-live performance standards so that post-implementation deviations can be detected and addressed proactively.
Question 4: Which tool category is most appropriate for monitoring real-time application performance in an enterprise implementation?
- Version control systems
- Application Performance Management (APM) tools (Correct answer)
- Helpdesk ticketing systems
- Code review platforms
Correct answer: Application Performance Management (APM) tools
APM tools provide real-time visibility into application behavior, response times, error rates, and resource utilization critical for ongoing performance management.
Question 5: When implementing a Service Level Agreement (SLA) for system performance, which element is essential to include?
- A list of all developer names on the project
- Defined performance thresholds, measurement methods, and consequences for non-compliance (Correct answer)
- The vendor's internal pricing structure
- End-user password policies
Correct answer: Defined performance thresholds, measurement methods, and consequences for non-compliance
An SLA must specify measurable thresholds, how performance will be monitored, and what remedies apply when targets are missed to be enforceable and useful.
Question 6: A CIS specialist is asked to reduce the load on a production server that handles high concurrent user traffic. Which strategy is MOST effective?
- Removing user accounts to limit concurrent sessions
- Implementing load balancing across multiple servers (Correct answer)
- Disabling scheduled reports during business hours only
- Increasing session timeout values
Correct answer: Implementing load balancing across multiple servers
Load balancing distributes incoming traffic across multiple servers, preventing any single server from becoming a bottleneck under high concurrent usage.
Question 7: What is the primary purpose of conducting a post-implementation performance review at 30, 60, and 90 days after go-live?
- To justify the implementation budget to executives
- To identify performance trends, resolve lingering issues, and confirm the system meets business requirements over time (Correct answer)
- To retrain all end users on system features
- To migrate data to a new system
Correct answer: To identify performance trends, resolve lingering issues, and confirm the system meets business requirements over time
Staged post-implementation reviews capture whether performance stabilizes or degrades over time and ensure the system continues to meet business needs as usage grows.
