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.
DOMAIN 1: ZABBIX ARCHITECTURE AND INSTALLATION (25 QUESTIONS)
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 frontend
B. Zabbix server
C. Zabbix agent
D. Zabbix proxy
CorreCt Answer: B ✓
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
A systems administrator is planning a new Zabbix 7.0 deployment to monitor 5,000 devices with
,approximately 100,000 metrics collected every 60 seconds. Which database backend is
recommended by Zabbix for this scale?
A. SQLite, because it requires minimal configuration
B. MySQL or PostgreSQL, because they support partitioning, replication, and the performance
required for large-scale production environments
C. Oracle Database, because it is the only database officially supported for enterprise licensing
D. Microsoft SQL Server, because it offers superior Windows integration
CorreCt Answer: B ✓
rAtionAle: Zabbix officially supports MySQL and PostgreSQL as production database
backends, both of which provide the partitioning, replication, and performance tuning
capabilities necessary for large-scale deployments with high metric volumes. SQLite is explicitly
not recommended for production.
Question 3
What is the primary purpose of a Zabbix proxy?
A. To replace the Zabbix server entirely
B. To collect monitoring data on behalf of the server, reducing load and enabling monitoring of
remote or segmented networks
C. To store historical data permanently
D. To provide the web interface
CorreCt Answer: B ✓
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 4
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 5
During installation, which configuration file is the main server configuration file?
, A. zabbix_agentd.conf
B. zabbix_server.conf
C. zabbix_proxy.conf
D. zabbix_web.conf
CorreCt Answer: B ✓
rAtionAle: The zabbix_server.conf file is the main configuration file for the Zabbix server. It
contains parameters for database connection, logging, cache sizes, and other server-specific
settings.
Question 6
An organization is deploying Zabbix server on a Linux platform and must ensure the server
meets minimum hardware requirements for monitoring 2,000 hosts. Which configuration
represents the minimum recommended resources?
A. 1 CPU core, 2 GB RAM, and SATA storage
B. 2 CPU cores, 8 GB RAM, and SSD storage
C. 4 CPU cores, 16 GB RAM, and NVMe storage
D. 8 CPU cores, 32 GB RAM, and SAN-attached storage
CorreCt Answer: B ✓
rAtionAle: For monitoring approximately 2,000 hosts, Zabbix recommends a minimum of 2
CPU cores and 8 GB RAM with fast storage (SSD) to handle the database I/O demands.
Question 7
A Zabbix administrator needs to deploy the Zabbix server with high availability using the native
HA feature introduced in Zabbix 6.0. Which requirement is mandatory for configuring Zabbix
server HA?
A. A shared network file system (NFS) for all Zabbix server nodes
B. A shared database backend accessible by all HA nodes and unique NodeName parameters
in the configuration
C. A load balancer configured with sticky sessions in front of the Zabbix server nodes
D. Pacemaker and Corosync clustering software installed on each node
CorreCt Answer: B ✓
rAtionAle: Zabbix native HA requires all nodes to connect to the same database and each
node must have a unique NodeName configured in zabbix_server.conf. A load balancer is used
for frontend HA, not server HA.
Question 8
Which of the following is NOT a supported installation method for Zabbix?
