Which command is used to create a read-only community string for SNMP?

1. (config)#snmp-server community NAME ro

2. (config)#snmp-server create community NAME

3. (config)#snmp-server access NAME read-only

4. (config)#snmp-server establish community NAME

The correct answer is: (config)#snmp-server community NAME ro

The correct answer for creating a read-only community string for SNMP is indeed the command that specifies the community name followed by the "ro" keyword. This command establishes a community string that provides read-only access to the SNMP data on the device, which is essential for monitoring purposes while restricting the ability to change configurations. In this context, the use of "ro" stands for "read-only," ensuring that any SNMP management station utilizing this community string can access and retrieve data from the network device but cannot modify its configuration. This is a common practice to maintain security while still allowing necessary monitoring and management. The other options do not correctly define the process for setting up a read-only community string. They either misrepresent how SNMP community strings are created or utilize incorrect syntax, which would not fulfill the intended goal of assigning read-only access for SNMP on the device.
