,Introduction
This assessment is designed to evaluate advanced competency in Zabbix monitoring
systems through scenario-based analysis and decision-making. Candidates are expected to
demonstrate the ability to synthesize technical knowledge, evaluate competing solutions,
and apply best practices in complex, real-world monitoring environments. Each question
emphasizes practical application, requiring deep understanding of system behavior,
optimization strategies, and operational trade-offs.
Questions 1–35
1. A financial institution experiences intermittent latency spikes across multiple
application servers. Metrics are collected via Zabbix agent, but spikes are missed.
What is the most effective configuration adjustment?
A. Increase item update interval to reduce load
B. Implement trapper items with external scripts
C. Reduce item update interval and enable preprocessing aggregation
D. Switch all items to SNMP polling
Correct Answer: C. Reduce item update interval and enable preprocessing
aggregation
Rationale: Reducing the interval increases sampling frequency, capturing spikes.
, Preprocessing aggregation prevents overload. A increases risk of missing spikes; B adds
complexity without solving sampling; D is less efficient than agents.
2. A Zabbix proxy is deployed in a remote site with unreliable connectivity. Data loss
occurs during outages. What is the optimal solution?
A. Increase proxy cache size
B. Disable proxy buffering
C. Switch to active agents only
D. Reduce item polling frequency
Correct Answer: A. Increase proxy cache size
Rationale: Larger cache allows buffering during outages. B removes resilience; C doesn't
address proxy storage; D reduces data granularity.
3. A trigger frequently flaps due to minor metric fluctuations. What is the best
approach?
A. Increase severity
B. Add hysteresis using recovery expression
C. Reduce polling interval
D. Disable trigger dependencies
Correct Answer: B. Add hysteresis using recovery expression
Rationale: Hysteresis stabilizes triggers. A doesn’t solve flapping; C may worsen it; D
unrelated.
, 4. An administrator wants to monitor dynamic Docker containers. What is the best
method?
A. Static host configuration
B. Low-Level Discovery (LLD)
C. Manual item creation
D. SNMP traps
Correct Answer: B. Low-Level Discovery (LLD)
Rationale: LLD dynamically discovers changing resources. Others are static or irrelevant.
5. A trigger must detect if CPU load exceeds 80% for 5 minutes continuously. What
function is most appropriate?
A. avg()
B. last()
C. min()
D. nodata()
Correct Answer: A. avg()
Rationale: avg() over time ensures sustained condition. last() is instantaneous; min()
checks lowest; nodata() checks absence.
6. A user reports delayed alerts. Logs show high poller utilization. What should be
adjusted first?
A. Increase number of pollers
B. Reduce frontend sessions
C. Disable triggers
