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

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.

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}
