What is the typical default SNMP version number used during configuration?

1. 1

2. 2c

3. 3

4. 5

The correct answer is: 2c

The typical default SNMP version number used during configuration is version 2c. Simple Network Management Protocol (SNMP) has evolved through different versions, and while version 1 was the first, it offered limited functionality and security features. Version 2c introduced improvements such as enhanced performance and additional protocol operations. In practice, many network devices and management systems default to SNMP version 2c because it strikes a balance between functionality and simplicity, allowing for more efficient data retrieval and support for bulk retrieval of data. Version 3, although more secure due to its additional features like encryption and authentication mechanisms, is often not the default due to its complexity in setup and configuration compared to version 2c. The choice of version 5 is misleading as it does not exist in the context of SNMP standards, reaffirming that version 2c is the correct and common default for many network devices.
