1. What is the primary role of a Zabbix proxy in large-scale deployments?
A. Store long-term historical data
B. Replace the Zabbix server
C. Collect and buffer monitoring data before sending to server
D. Manage user authentication
Answer: C
Rationale: Zabbix proxies reduce load on the server by collecting and
temporarily storing monitoring data before forwarding it.
2. Which database is most commonly recommended for large-scale
Zabbix deployments?
A. SQLite
B. MySQL/MariaDB or PostgreSQL
, C. MongoDB
D. Redis
Answer: B
Rationale: Zabbix supports relational databases, with
MySQL/MariaDB and PostgreSQL being preferred for scalability.
3. What is a major benefit of using active agent checks?
A. Server initiates all checks
B. Agents pull configuration from server only
C. Reduces firewall restrictions and server load
D. Disables encryption
Answer: C
Rationale: Active agents reduce load on the server and avoid inbound
firewall requirements.
4. What component stores configuration data in Zabbix?
A. History table
B. Events table
C. Configuration database
D. Proxy cache
Answer: C
Rationale: All configuration data is stored centrally in the Zabbix
database.
5. What is the function of Zabbix preprocessing?
A. Encrypt traffic
, B. Filter and transform incoming metrics before storage
C. Replace triggers
D. Manage users
Answer: B
Rationale: Preprocessing allows data transformation, validation, and
filtering before storage.
6. Which Zabbix component handles data collection from agents and
SNMP devices?
A. Zabbix frontend
B. Zabbix server
C. Zabbix API
D. Zabbix proxy UI
Answer: B
Rationale: The Zabbix server is responsible for collecting data from
monitored hosts and proxies.
7. What is the main scalability limitation of a single Zabbix server?
A. CPU only
B. Network bandwidth only
C. Database performance bottleneck
D. Agent limitations
Answer: C
Rationale: The database becomes the primary bottleneck in large-
scale environments.
, 8. What does housekeeping in Zabbix refer to?
A. User management
B. Cleaning outdated historical data
C. Proxy configuration
D. Template creation
Answer: B
Rationale: Housekeeping removes old data from history and trends
tables.
9. Which Zabbix feature helps distribute monitoring across geographic
locations?
A. Triggers
B. Proxies
C. Templates
D. Actions
Answer: B
Rationale: Proxies enable distributed monitoring across remote sites.
10. What is required for Zabbix agent encryption?
A. SSH keys
