2026/2027 Verified Questions Zabbix LLC Zabbix Certified Specialist Comprehensive Examination
Professional IT Candidates 100 Ver, with the strongest emphasis placed on Design and
troubleshoot distributed Zabbix architectures including server, proxy, agent, and agent2 roles under
high-availability and network-isolated conditions, Construct and debug advanced trigger
expressions, dependent items, calculated items, and low-level discovery rules with correct macro
context and precedence, Apply preprocessing, value mapping and and item value types to
normalize heterogeneous telemetry while preserving data integrity and history/trend retention
semantics. Every item follows the wording style and level of reasoning you meet in the real paper,
and each one is paired with a clear rationale so the correct choice is never a guess. Work through
the set at your own pace, mark the questions that slow you down, then come back to them until the
reasoning feels automatic. Learners who revise this way walk into the exam room recognising the
pattern behind the questions instead of meeting them for the first time. Keep going - steady, honest
practice is what turns a difficult paper into a comfortable pass.
Q1 DESIGN AND TROUBLESHOOT DISTRIBUTED ZABBIX ARCHITECTURES INCLUDING
SERVER, PROXY, AGENT, AND AGENT2 ROLES UNDER HIGH-AVAILABILITY AND
NETWORK-ISOLATED CONDITIONS
A monitored host is reachable only through a Zabbix proxy operating in active
mode. The proxy loses its connection to the server for 45 minutes, then
reconnects. Which statement correctly describes the data-handling behavior
during and after the outage?
A. The proxy buffers collected values locally and forwards them to the server upon reconnection;
the server timestamps them at original collection time, subject to the proxy's local buffer
configuration. CORRECT
B. The proxy discards all values collected during the outage because active proxies cannot store
data without a live server connection.
C. The server retrieves the buffered values only if the proxy is configured with a passive mode
fallback; otherwise data is permanently lost.
D. Values are forwarded but re-timestamped at reconnection time, causing all trigger events to
fire simultaneously in a burst.
RATIONALE: Active proxies buffer unsent data locally and transmit it on reconnection, preserving
original collection timestamps (subject to buffer size limits). B is false because active proxies do
buffer; C misstates the mechanism-no passive fallback is required; D is wrong because original
timestamps are retained, not overwritten at reconnection.

, Q2 DESIGN AND TROUBLESHOOT DISTRIBUTED ZABBIX ARCHITECTURES INCLUDING
SERVER, PROXY, AGENT, AND AGENT2 ROLES UNDER HIGH-AVAILABILITY AND
NETWORK-ISOLATED CONDITIONS
An engineer writes a trigger expression: {host:item.avg(5m)}>90 &
{host:item.avg(5m)}<100. The item has a 1-minute update interval. What is the
most significant semantic flaw in this expression for detecting a sustained
high-load condition?
A. The avg() function cannot be combined with two comparisons in a single trigger expression.
B. Both functions reference the same 5-minute window, so the two conditions are evaluated over
identical samples and the expression effectively tests a single averaged value, not a sustained
range. CORRECT
C. The trigger will always evaluate to true because Zabbix treats '&' as a logical OR in trigger
expressions.
D. The 5m window is invalid when the item interval is 1m; Zabbix requires the window to be an
integer multiple of the interval greater than 10m.
RATIONALE: Both avg(5m) calls draw from the same 5-minute sample set, so the trigger tests a
single averaged scalar rather than a sustained condition-there is no temporal separation between
the two thresholds. A is false (multiple comparisons are allowed), C inverts the operator
semantics, and D invents a nonexistent interval-multiple rule.
