What are the four steps that occur when SNMP traps are sent from a device to
Zabbix server? - Answer-1. snmptrapd receives a trap and passes trap to trap
receiver
, 2. Trap receiver parses, formats and writes trap to a file

IPMI sensor
What command line tool do you use to retrieve IPMI sensor information? - Answer-
ipmitool

When adding a calculated check, in which field do you add the calculation? -
Answer-Formula
What two value types can be the result of a calculation check? - Answer-Numeric,
Character
What can be updated with Mass Update on an Host? - Answer-General properties,
link or unlink or replace templates, IPMI, encryption, macros, inventory mode, value
mappings, tags
What standalone command-line utility is used to set up a trapper item to send data? -
Answer-zabbix_sender
What four values do you need to specify when running zabbix_sender and what
character denotes them when running the command? - Answer--z IP or DNS, -s Host
name, =k Item key, -o Value
