Exam N10-008 topic 1 question 274 discussion

I agree OID is what SIEM uses to gather and report on specific data from device. but the question states " monitor the temperatures of all the devices". you need something to get all the data from all the devices, and that would be a SIEM Service.

An OID is an object identifier value, typically an address used to identify a particular device and its status. For example, you want to monitor a remote temperature sensor sitting on the roof of your building. But there are three different temperature sensors placed in different parts of the roof. How can you check the value of the sensor located on the eastern side of the roof? Using the unique OID associated with each device. In other words, each device has its own unique OID and using that you can track the performance and status of that particular device.

Yes, when the question refers to a command, it's referring to the use of SNMP messages/queries to interact with the network devices and retrieve the desired information, such as temperature data, associated with specific OIDs (Object Identifiers). In practice, an SNMP GET request (which is a type of SNMP message) would be issued, specifying the OID(s) associated with temperature data. The network device, equipped with an SNMP agent, would then respond to the SNMP GET request with the current temperature values.

A COMMAND

Use SNMP: Many network devices support the Simple Network Management Protocol (SNMP), which allows you to monitor various aspects of a device, including temperature. You can use SNMP monitoring tools to query temperature-related SNMP OIDs (Object Identifiers) on the device. Popular SNMP monitoring tools like Nagios, Cacti, or PRTG can help with this.

SNMP (Simple Network Management Protocol) is commonly used for monitoring and managing network devices. SNMP allows you to retrieve various types of information from network devices, including temperature data from devices equipped with temperature sensors. This information is accessible through specific SNMP OID (Object Identifier) values associated with temperature sensors on those devices. By querying the appropriate SNMP OID values, the network administrator can retrieve temperature information from devices and monitor their temperature status to prevent issues caused by overheating. Security Information and Event Management (SIEM) (D) systems are used for collecting, correlating, and analyzing security-related events, and they typically don't focus on temperature monitoring.

Snmp oid value = monitor temperatures, and if too high you can get notifications from a Snmp Trap. Siem = Syslog(for retrieving data log messages on a later stage.

A is the correct answer. don't let the acronyms confuse you

Would Security information and event management not make the most sense?

A. SNMP OID values. SNMP OID values would likely be the best option for retrieving temperature information from network devices. SNMP (Simple Network Management Protocol) is a protocol that is commonly used to monitor and manage network devices. SNMP uses OID (Object Identifier) values to identify and retrieve information from specific objects within a network device. Many network devices, including routers, switches, and servers, support SNMP and can provide information such as temperature readings through OID values. Security information and event management (SIEM) is a security-focused approach to monitoring and managing network devices. While SIEM can be used to collect and analyze temperature information, it is not the most direct or efficient method for retrieving this information. SIEM is typically used to collect and analyze security-related information such as log data, rather than device-specific information like temperature readings.

The best way to retrieve the necessary information to monitor the temperatures of all the devices is to use SNMP OID values. SNMP stands for Simple Network Management Protocol, a standard protocol for managing and monitoring network devices. SNMP uses a hierarchical structure of Object Identifiers (OIDs) to identify and access various attributes of network devices, such as their status, performance, configuration, and temperature. Using an SNMP monitoring tool, such as PRTG Network Monitor or SolarWinds Network Performance Monitor, the support team can query the SNMP OID values of the devices and display them in a graphical dashboard or report. The support team can also set thresholds and alerts for the temperature values to be notified of any abnormal or critical conditions.

A. SNMP OID values SNMP (Simple Network Management Protocol) is a protocol used for managing and monitoring network devices. SNMP uses OID (Object Identifier) values to identify and retrieve information about specific parameters of a device, including temperature. Therefore, using SNMP OID values is the most appropriate way to retrieve the necessary temperature information in this scenario.

The SNMP OID values will retrieve the necessary information. SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices. It allows network administrators to retrieve information from network devices, including temperature and other environmental data. The temperature data is typically stored in a specific OID (Object Identifier) value within the SNMP MIB (Management Information Base) of the device. Therefore, by querying the SNMP OID values of the devices, the network administrator can retrieve the necessary temperature information and monitor it to prevent future network outages caused by HVAC failures.

A. SNMP OID values (SNMP stands for Simple Network Management Protocol, it's a protocol used to manage and monitor devices in a network. It allows an administrator to retrieve information from devices, such as temperature, through the use of Object Identifiers (OIDs) which are used to identify specific information on the device.)

Security information and event management (SIEM) is a security management system that aggregates and analyzes security-related data from a variety of sources, including network devices, servers, and applications. SIEM can be used to identify security threats and vulnerabilities, but it does not include information about device temperatures or other environmental factors.

A. SNMP OID values (Object Identifier values) are used to identify specific objects or variables in the Simple Network Management Protocol (SNMP). SNMP is a widely used protocol for managing and monitoring network devices, such as routers, switches, and servers. By querying the appropriate OID values, you can retrieve a wide range of information about a device, including its temperature, CPU utilization, memory usage, and other metrics.
