1. What is the primary purpose of the Zabbix preprocessing fea-
ture?
A) To store historical data in the database
B) To transform or filter collected data before storage
C) To generate notifications for triggers
D) To manage user permissions in the frontend
Correct Answer: B
Rationale: The preprocessing feature in Zabbix allows for the transformation or fil-
tering of collected data before it is stored in the database. This includes operations
like data validation, unit conversion, or regular expression matching to ensure data
consistency and usability.
2. Which Zabbix component is responsible for executing sched-
uled tasks like discovery and auto-registration?
A) Poller
B) Housekeeper
C) Scheduler
D) Data Collector
Correct Answer: C
Rationale: The Scheduler component in Zabbix handles scheduled tasks such as
network discovery, auto-registration, and low-level discovery (LLD), ensuring these
processes run at defined intervals.
3. What is the default port used by the Zabbix Java Gateway?
A) 10050
B) 10051
C) 10052
D) 10053
Correct Answer: C
Rationale: The Zabbix Java Gateway uses port 10052 by default to facilitate JMX

,(Java Management Extensions) monitoring, allowing Zabbix to collect data from Java-
based applications.
4. How does Zabbix handle unsupported items when monitoring a
host?
A) Marks them as disabled and stops polling
B) Retries polling indefinitely
C) Converts them to passive checks
D) Deletes them automatically
Correct Answer: A
Rationale: When an item becomes unsupported, Zabbix marks it as disabled and
stops polling it to prevent unnecessary resource usage, while still retaining the item
configuration.
5. Which configuration file must be modified to enable Zabbix
Agent active checks?
A) zabbix_server.conf
B) zabbix_agentd.conf
C) zabbix_proxy.conf
D) zabbix_web.conf
Correct Answer: B
Rationale: The zabbix_agentd.conf file is used to configure the Zabbix Agent, includ-
ing enabling active checks by setting the ServerActive parameter and specifying the
Zabbix server or proxy address.
6. What is the purpose of the Zabbix sender utility?
A) To collect data from passive agents
B) To send trapper item data to the Zabbix server
C) To configure host interfaces
D) To perform network discovery
Correct Answer: B
Rationale: The Zabbix sender utility is a command-line tool used to send data to
trapper items on the Zabbix server, allowing external applications or scripts to push
data to Zabbix.
7. Which database is NOT supported by Zabbix 7.0 for storing con-
figuration and historical data?
A) MySQL

, B) PostgreSQL
C) SQLite
D) Oracle
Correct Answer: C
Rationale: Zabbix 7.0 supports MySQL, PostgreSQL, and Oracle for storing config-
uration and historical data, but SQLite is only supported for Zabbix proxy databases,
not the main server.
8. What happens if a Zabbix proxy is in active mode and loses
connection to the Zabbix server?
A) It stops collecting data
B) It buffers data locally until reconnection
C) It switches to passive mode automatically
D) It deletes all collected data
Correct Answer: B
Rationale: In active mode, a Zabbix proxy buffers data locally in its database when
the connection to the Zabbix server is lost, ensuring no data is lost until the connection
is restored.
9. Which macro is used to reference the last received value of an
item in Zabbix?
A) {ITEM.VALUE}
B) {ITEM.LASTVALUE}
C) {ITEM.HISTORY}
D) {ITEM.PREVVALUE}
Correct Answer: A
Rationale: The {ITEM.VALUE} macro is used in Zabbix to reference the last received
value of an item, commonly used in triggers, notifications, and scripts.
