1. What is the primary purpose of Zabbix preprocessing in item
configuration?
A. To increase server performance
B. To transform or filter collected data before storing it
C. To configure database replication
D. To manage user permissions
Answer: B. To transform or filter collected data before storing it
Rationale: Preprocessing in Zabbix allows modification of
incoming item values, such as JSONPath extraction, regex
filtering, or unit conversion, before data is stored in the
database, improving accuracy and usability.
2. Which Zabbix component is responsible for collecting metrics
from monitored hosts?
A. Zabbix server
, B. Zabbix frontend
C. Zabbix agent
D. Zabbix database
Answer: C. Zabbix agent
Rationale: The Zabbix agent runs on monitored hosts and
collects system-level metrics such as CPU usage, memory, and
disk utilization, then sends them to the Zabbix server.
3. What is a Zabbix proxy primarily used for?
A. Encrypting frontend traffic
B. Reducing load on the Zabbix server by collecting data locally
C. Managing user authentication
D. Storing historical reports only
Answer: B. Reducing load on the Zabbix server by collecting data
locally
Rationale: A Zabbix proxy gathers monitoring data from hosts in
a defined region and forwards it to the Zabbix server, reducing
bandwidth usage and server load.
4. Which database is NOT officially supported by Zabbix server?
A. MySQL
, B. PostgreSQL
C. Oracle
D. SQLite for production server
Answer: D. SQLite for production server
Rationale: SQLite is only supported for lightweight or embedded
setups and is not recommended or officially supported for
production Zabbix server deployments.
5. What is the function of Zabbix triggers?
A. Collect raw metrics
B. Execute remote scripts
C. Evaluate item data and generate alerts
D. Store historical data
Answer: C. Evaluate item data and generate alerts
Rationale: Triggers define logical expressions based on item
values and generate problems when conditions are met.
6. Which Zabbix item type allows executing external scripts on the
server?
A. Zabbix agent
B. Simple check
, C. External check
D. SNMP trap
Answer: C. External check
Rationale: External checks execute scripts on the Zabbix server
side to retrieve or calculate data.
7. What is the default port used by Zabbix server?
A. 80
B. 443
C. 10051
D. 10050
Answer: C. 10051
Rationale: Zabbix server listens on port 10051 for incoming data
from agents and proxies.
8. Which item type is used for passive checks in Zabbix agent
monitoring?
A. Active checks
B. Passive checks
C. Trapper items
D. Dependent items
