Question 1
What is the primary purpose of High Availability (HA) in Zabbix
deployments?
A. Increase database storage capacity
B. Ensure continuous monitoring service uptime
C. Improve UI responsiveness
D. Reduce number of monitored hosts
Correct answer: B
Rationale: HA in Zabbix is designed to eliminate single points of
failure, ensuring that monitoring services remain operational even if
one or more components fail.
Question 2
,Which Zabbix component is typically made highly available in a
production HA setup?
A. Zabbix Agent only
B. Zabbix Server
C. SNMP devices
D. Item keys
Correct answer: B
Rationale: The Zabbix Server is the central processing component and
is most commonly deployed in HA configurations to prevent
monitoring downtime.
Question 3
What database setup is commonly used with Zabbix HA?
A. Local SQLite database
B. Single-node MySQL only
C. Replicated database cluster
D. Flat file storage
Correct answer: C
Rationale: HA deployments typically rely on replicated database
clusters (MySQL, PostgreSQL, or Oracle) to ensure data availability
and consistency.
,Question 4
What is a common method for achieving Zabbix Server HA?
A. RAID 0 configuration
B. Active-passive clustering
C. Static routing
D. DNS caching
Correct answer: B
Rationale: Active-passive clustering allows one node to take over
when the primary server fails, ensuring continuity.
Question 5
Which tool is commonly used for Linux-based HA resource management
in Zabbix setups?
A. Apache Tomcat
B. Pacemaker
C. IIS
D. Docker Swarm only
Correct answer: B
Rationale: Pacemaker is widely used with Corosync to manage failover
resources in Linux HA clusters.
, Question 6
What role does a virtual IP (VIP) play in Zabbix HA?
A. Encrypt database traffic
B. Replace SNMP polling
C. Provide a single access point for clients
D. Store historical metrics
Correct answer: C
Rationale: A VIP allows clients to connect to a single IP address
regardless of which backend node is active.
Question 7
Which component often handles failover detection in HA clusters?
A. Corosync
B. Apache
C. Nginx
D. SNMP trapper
Correct answer: A
Rationale: Corosync provides cluster communication and heartbeat
mechanisms for node health monitoring.
