Why each option
Community strings in SNMP operations function as a simple form of password to control and protect access to Management Information Base (MIB) objects on managed devices.
Community strings do not function as sequence tags; their primary role is authentication and authorization for MIB access.
SNMP community strings serve as a plain-text password that authenticates requests to the SNMP agent and authorizes access to MIB objects, defining either read-only or read-write permissions for specific OIDs. Devices configured with the correct community string can access the agent's MIB data.
SNMP community strings are distinct from Active Directory credentials and are not used to pass username and password information for device access.
Community strings are for access control, not for translating MIB output values, which are defined by the MIB structure itself.
