Zabbix Certified Specialist Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This Comprehensive Certification Examination contains exactly 100 original verified questions designed
to reinforce the official Zabbix LLC Zabbix Certified Specialist Examination course objectives for actual
exam readiness and professional proficiency, aligned to the 2026/2027 academic year. The questions are
organized across four core domains: Domain 1 – Zabbix Architecture and Installation (25 questions);
Domain 2 – Item and Trigger Configuration (25 questions); Domain 3 – Templates and Low-Level
Discovery (25 questions); and Domain 4 – Advanced Monitoring, Maintenance, and Troubleshooting (25
questions). Each question is accompanied by the correct answer and a detailed rationale grounded in
foundational IT monitoring methodology, including principles drawn from the official Zabbix
documentation and Certified Specialist course materials. The content emphasizes architectural
understanding, precise item and trigger configuration, template and discovery design, and operational
troubleshooting of Zabbix monitoring environments.
ACTUAL QUESTIONS
Domain 1: Zabbix Architecture and Installation
Question 1. Which component of the Zabbix architecture is responsible for collecting data
from agents, proxies, and other sources and writing it to the database?
A. Zabbix server
B. Zabbix frontend
C. Zabbix agent
D. Zabbix proxy only
Correct Answer: A
Rationale: The Zabbix server is the central process that performs polling, trap processing, alert
generation, and database writes. The frontend is the web UI; agents and proxies collect or forward
data.
Question 2. What is the primary purpose of a Zabbix proxy?
A. To replace the Zabbix server entirely
B. To store historical data permanently
C. To collect monitoring data on behalf of the server, reducing load and enabling monitoring of
remote or segmented networks
D. To provide the web interface
Correct Answer: C
Rationale: Proxies offload data collection, buffer data during network outages, and allow monitoring
across firewalls or remote sites while the server remains the single source of truth.
Question 3. Which database engines are officially supported by Zabbix for the server
backend?
A. MySQL/MariaDB, PostgreSQL, and TimescaleDB (as a PostgreSQL extension)
B. Only SQLite for production
C. Oracle Database exclusively
D. MongoDB and Cassandra
Correct Answer: A
Rationale: Zabbix officially supports MySQL/MariaDB and PostgreSQL. TimescaleDB can be used with
PostgreSQL for improved history performance. SQLite is limited to very small or proxy deployments.
Question 4. During installation, which configuration file is the main server configuration
file?
A. zabbix_agentd.conf
Zabbix Certified Specialist Comprehensive Examination 2026/2027 | Verified Questions
, B. zabbix_server.conf
C. zabbix_proxy.conf
D. php.ini only
Correct Answer: B
Rationale: zabbix_server.conf contains all server-side parameters such as DB connection, poller counts,
cache sizes, and log settings. Agent and proxy have their own distinct configuration files.
Question 5. What is the default TCP port used by the Zabbix agent for passive checks?
A. 10051
B. 80
C. 10050
D. 443
Correct Answer: C
Rationale: The Zabbix agent listens on port 10050 for passive checks initiated by the server or proxy.
Port 10051 is used by the server/proxy for trapper items and active agent connections.
Question 6. Which process is responsible for sending notifications (email, SMS, scripts)
when triggers fire?
A. Zabbix server (alerter processes)
B. Zabbix agent
C. Zabbix frontend only
D. External database triggers
Correct Answer: A
Rationale: The server’s alerter processes evaluate media types and send notifications. The frontend is
used to configure media types and user media; actual delivery is performed by the server.
Question 7. In a distributed setup, what is the recommended way to monitor hosts behind a
firewall that does not allow inbound connections to the Zabbix server?
A. Open all inbound ports permanently
B. Use only SNMP traps without any proxy
C. Install a second independent Zabbix server
D. Deploy a Zabbix proxy in the remote network that initiates outbound connections to the server
Correct Answer: D
Rationale: A proxy can be configured in active mode to connect outbound to the server, collecting data
locally and forwarding it, thereby avoiding inbound firewall rules to the central server.
Question 8. Which user in the Zabbix frontend has full administrative rights by default
after a fresh installation?
A. Guest
B. Any newly created user
C. Admin (with the Zabbix Administrators user group)
D. The database superuser only
Correct Answer: C
Rationale: The default Admin user belongs to the Zabbix Administrators group and has Super admin
privileges. It is strongly recommended to change the default password immediately after installation.
Question 9. What does the StartPollers parameter in zabbix_server.conf control?
A. The number of processes that perform passive checks (agent, SNMP, simple checks, etc.)
B. The number of web frontend workers
C. The size of the history cache
