ZABBIX CERTIFIED SPECIALIST EXAM DAY 3 CERTIFICATION EXAM NEWEST 2025 ACTUAL EXAM
COMPLETE 100 QUESTIONS AND CORRECT DETAILED ANSWERS
What will happen to problems if the trigger they depend on is in the PROBLEM state? - (ANSWER)They
will be suppressed
Where can dependencies between triggers be defined? - (ANSWER)On the same host or on different
hosts
What is a Zabbix agent passive check? - (ANSWER)Zabbix server or proxy asks for a single metric and
Zabbix agent sends back the result.
What does not matter at all for passive checks? - (ANSWER)Host name
What must be specified to allow connectivity between Zabbix Server and Zabbix Agent? -
(ANSWER)Server parameter must match Zabbix server or proxy IP address (or subnet).
What is the default number of pollers that are started at once? - (ANSWER)5
What is the Zabbix server timeout (connection timeout)? - (ANSWER)The number of seconds the Zabbix
server will wait for an answer from the agent.
What are 2 reasons for installing Zabbix_get? - (ANSWER)To gather data from the Agent, to run a passive
test, can be used in custom scripts.
What file needs to be edited to allow Zabbix Server to connect to Zabbix Agent? -
(ANSWER)/etc/zabbix/zabbix_agentd.conf
What command allows you to view the list of installed packages on a Zabbix Agent? -
(ANSWER)zabbix_get -s 127.0.0.1 -k system.sw.packages[zabbix]
Can Zabbix agent be installed on Windows? - (ANSWER)Yes
,What field is mandatory for Zabbix agent to communicate in Active Mode? - (ANSWER)Hostname, it
must be defined the same on both the frontend host & in the zabbix_agentd.conf file.
On which port is data from active Agents accepted? And by what process? - (ANSWER)Port 10051, by
trapper process.
Are interfaces required for Active Agent checks? - (ANSWER)No
What value in the zabbix_agentd.conf file needs to be updated with the Zabbix Server or Proxy IP
address? - (ANSWER)ServerActive
What command is used to return the Zabbix Agent hostname? - (ANSWER)zabbix_agentd -t
system.hostname.
In the zabbix_agentd.conf file, what happens if multiple IP addresses are listed under the ServerActive
field? - (ANSWER)It will send data to all listed servers.
How often does the Agent retrieve configuration data from the Zabbix Server? - (ANSWER)On agent start
and every 2 minutes.
Where does the Zabbix agent store collected values when in active mode? And how often is the data
sent? - (ANSWER)Memory buffer (every 5 seconds by default).
Do active checks use an availability icon? - (ANSWER)No, must refer to latest data.
What must you do after updating the hostname on an agent? And what is the command to do this? -
(ANSWER)You must restart the agent using the command "systemctl restart zabbix-agent".
What is the default hostname on new Agent installations and why is this a problem? - (ANSWER)Zabbix
server, hostname must be unique otherwise the data will be represented under the host called Zabbix
server.
,Why are Active checks more precise? - (ANSWER)Because the UNIXTIME is exact when the log is
generated on the device running the agent.
What is the main purpose of UserParameters? - (ANSWER)Allows you to run a check that does not come
predefined with Zabbix i.e. Linux command.
What must be unique on the Zabbix agent in regards to UserParameters? - (ANSWER)Keys.
Can you reload userparameters without restarting the Zabbix agent? If so, what is the command? -
(ANSWER)Yes, zabbix_agentd -R userparameter_reload
What is the sytnax for UserParameters? - (ANSWER)UserParameter=key,command
How do you run a UserParameter script? - (ANSWER)zabbix_agentd -t mykey
Why should you not configure a UserParameter that takes a long time to finish? - (ANSWER)They will
respect timeouts defined in the server and agent configuration and likely timeout.
If you change how data is shown in the frontend, does it modify the data in the database? - (ANSWER)No
What character can be used to prevent a unit from being converted using special processing? -
(ANSWER)Exclamation mark "!" before the unit value.
If you define the unit "unixtime" under an item, how will it display on the frontend portal? -
(ANSWER)2023.03.21 13:28:32
What information types support value maps between raw values and string representations? -
(ANSWER)Numeric (unsigned), numeric (float), Character.
If multiple mappings overlap, what match will be applied? - (ANSWER)First.
, Which three Item types cannot have update intervals defined? - (ANSWER)Zabbix trapper, SNMP trapper,
Dependent items.
What is the minimum allowed update interval? - (ANSWER)1 second.
What is the default update interval metric if a suffix is not set? - (ANSWER)Seconds.
What is one reason why you might want to setup flexible update intervals? And if multiple exist, which
takes precedence? - (ANSWER)To retrieve data less frequently outside of business hours. Lowest interval
takes precedence.
What are the five different time values for setting scheduling intervals and what do they mean? -
(ANSWER)md; month days (1-31), wd; week days (1-7), h; hours (0-23), m; minutes (0-59), s; seconds (0-
59).
Can custom intervals be used for active checks? - (ANSWER)Yes, but only for Zabbix agent 2.
What is the difference between Flexible and Scheduling custom intervals? - (ANSWER)Flexible custom
interval you define an interval and a period (lowest value takes precedence), Scheduling is where you
define a specific time(s) that you want the check to happen (on the minute, on the hour etc).
How are transformations in pre-processing handled i.e. in what order? - (ANSWER)In the order they are
defined.
What happens if a preprocessing step fails? - (ANSWER)All preprocessing stops for that item.
What are the three options for 'custom on fail' scenarios in preprocessing? - (ANSWER)Discard value (&
no more steps are processed), Set value to (value will be changed to defined value), Set error to (item
will become not supported with custom error).
What happens to data that does not have any preprocessing steps defined? - (ANSWER)It is still passed
into preprocessing manager and placed into the preprocessing queue.
