* Management information bases (MIBs) are hierarchical databases of network objects that are defined
* using a subset of ASN.1 called SMIv212.
* MIBs describe the properties and capabilities of network devices that can be monitored and managed using SNMP12.
* MIBs are organized into modules that correspond to different standards, vendors, or applications12.
* MIBs are accessed by SNMP managers and agents using object identifiers (OIDs) that uniquely identify each network object12.
* MIBs are updated periodically to reflect changes in network technologies, protocols, or device features12.
* Updating the MIBs on the SNMP manager and agent is necessary to ensure compatibility and interoperability between different versions of network devices and operating systems12.
* Updating the MIBs can also enable new monitoring and management functions that are supported by the newer versions of network devices and operating systems12.
* B. System baseline is not a correct answer because a system baseline is a set of performance metrics that are obtained by measuring the network for a specific time period34.
* A system baseline is used to validate the current network status, identify trends, and plan for future changes34.
* A system baseline is not related to adding a new system to monitoring, as it does not define the network objects or the SNMP protocol34.
* C. Network device logs are not a correct answer because network device logs are records of events or activities that occur on network devices56.
* Network device logs are used to troubleshoot, audit, or analyze network performance and security issues56.
* Network device logs are not related to adding a new system to monitoring, as they do not define the network objects or the SNMP protocol56.
* D. SNMP traps are not a correct answer because SNMP traps are unsolicited messages that are sent by SNMP agents to SNMP managers when a significant event occurs on a network device78.
* SNMP traps are used to notify the network manager of urgent or abnormal situations that require attention78.
* SNMP traps are not related to adding a new system to monitoring, as they do not define the network objects or the SNMP protocol78.
