1. What is the primary purpose of a Zabbix proxy in distributed
monitoring?
A. To replace the Zabbix server
B. To store only historical data
C. To collect and forward monitoring data to the Zabbix server
D. To manage user permissions
Answer: C
Rationale: A Zabbix proxy acts as an intermediary, collecting data from
monitored hosts and forwarding it to the central Zabbix server.
2. Which database is required for Zabbix proxy operation?
A. MongoDB
, B. Cassandra
C. SQLite, MySQL, or PostgreSQL
D. Redis only
Answer: C
Rationale: Zabbix proxy supports lightweight SQLite or full databases like
MySQL/PostgreSQL depending on deployment needs.
3. Which mode allows a Zabbix proxy to send data immediately?
A. Passive mode
B. Standby mode
C. Active mode
D. Sync mode
Answer: C
Rationale: In active mode, proxies actively send collected data to the server
without waiting for requests.
4. What is stored in a Zabbix proxy temporarily?
A. User accounts
B. Configuration only
C. Monitoring data before sending to server
D. Web UI cache
,Answer: C
Rationale: Proxies buffer monitoring data locally when the server is

5. Which communication direction is used in passive proxy mode?
A. Proxy pushes data
B. Bidirectional sync
C. Server requests data from proxy
D. Host communicates directly with server only
Answer: C
Rationale: In passive mode, the server polls the proxy for collected data.
6. What is a key benefit of distributed monitoring using proxies?
A. Reduces UI load
B. Reduces load on central Zabbix server
C. Eliminates database usage
D. Disables triggers
Answer: B
Rationale: Proxies reduce server workload by handling data collection
locally.
7. Which component communicates directly with monitored hosts in
proxy setups?
A. Zabbix frontend
, B. Database
C. Zabbix proxy
D. API server
Answer: C
Rationale: Proxies directly collect metrics from hosts in remote locations.
8. What happens if a Zabbix proxy loses connection to the server?
A. Data is deleted
B. Hosts stop monitoring
C. Data is buffered locally
D. Server shuts down
Answer: C
Rationale: Proxies store collected data until connection is restored.
9. Which protocol is commonly used by Zabbix agents?
A. FTP
B. SMTP
C. Zabbix protocol (custom TCP)
D. SNMPv1 only
