1. An organization is designing a Zabbix monitoring
infrastructure for a global enterprise with 50,000 monitored
devices across three continents. The requirement specifies
sub-second data collection for critical network devices and
historical data retention of three years. Which architecture
best meets these requirements?
A. Single Zabbix server with default MySQL configuration and
passive agents only
B. Distributed Zabbix proxy deployment with active agents,
TimescaleDB partitioning, and separate history/trends storage
,C. Single Zabbix server with SQLite backend and aggressive
housekeeper settings
D. Zabbix proxy-only deployment without a central server for
autonomous regional operation
RATIONALE: A distributed proxy architecture with active
agents reduces WAN latency and server load for global
deployments. TimescaleDB provides hypertable partitioning for
efficient time-series storage and compression, supporting three-year
retention. Single-server architectures cannot scale to 50,000
devices. SQLite is unsuitable for production scale. Proxy-only
deployments lack centralized management and correlation
capabilities .
2. An organization is migrating from Zabbix 6.0 LTS to Zabbix
7.0 LTS. The database administrator reports that the upgrade
script has been executed successfully, but the frontend
displays a version mismatch error. Which step was most likely
omitted?
A. The Zabbix server binary was not restarted after the database
upgrade
B. The PHP opcache was not cleared after updating the frontend
files
C. The Zabbix proxy configuration files were not updated
simultaneously
,D. The database user privileges were not granted for the new schema
tables
RATIONALE: The Zabbix frontend caches PHP files in opcache;
failure to clear or restart the web server after frontend updates
causes persistent version mismatch errors between the cached
frontend and upgraded database schema. While server restart is
necessary, the version mismatch specifically indicates frontend
caching. Proxy updates are independent of server-frontend version
checks. Database privileges would cause connection errors, not
version mismatches .
3. A Zabbix administrator needs to monitor Docker containers
on a host without installing the Zabbix agent directly on each
container. Which monitoring approach is most appropriate?
A. Install Zabbix agent2 on the Docker host and use the Docker
plugin with the docker.by_item key
B. Deploy passive Zabbix agents inside each container with host
network mode
C. Use the Zabbix agent classic with UserParameter scripts calling
docker exec
D. Monitor containers exclusively through SNMP traps from the
Docker daemon
RATIONALE: Zabbix agent2 includes native Docker plugin
support that discovers and monitors containers from the host
without per-container agent installation, using the Docker API.
, Passive agents in each container create unnecessary overhead and
network complexity. UserParameter scripts are less efficient and
harder to maintain than native plugins. Docker daemon does not
emit SNMP traps natively .
4. An enterprise requires high availability for its Zabbix
monitoring infrastructure with automatic failover and no
single point of failure. Which configuration satisfies these
requirements?
A. Active-passive Zabbix server pair with shared database on a single
node
B. Active-active Zabbix server cluster with Galera Cluster for
synchronous database replication and HAProxy for frontend load
balancing
C. Two independent Zabbix servers with asynchronous database
replication and manual failover procedures
D. Single Zabbix server with RAID 10 storage and nightly database
backups
RATIONALE: Zabbix 7.0 supports native active-active server
clustering with frontend load balancing. Galera Cluster provides
synchronous multi-master database replication, ensuring data
consistency across nodes. HAProxy distributes frontend
connections. Active-passive configurations have failover delays.
Independent servers with manual failover do not meet automatic
failover requirements. Single servers with RAID remain single
points of failure .
