Refer to the exhibit. Which command set must be added to the configuration to analyze 50 packets out of every 100?

`interface GigabitEthernet 0/0/0 ip` is an incomplete command and only enters interface configuration mode; it does not configure packet sampling.

While `sampler SAMPLER-1` is correct for defining a sampler, the option provided `sampler SAMPLER-1` is the start of the configuration block for a sampler, not a complete command set for analysis without further configuration of the rate.

`flow monitor FLOW-MONITOR-1` defines a flow monitor, which specifies how flow data is collected and exported, but it does not define the *sampling rate* for packets; a separate sampler is required for that.

To analyze 50 packets out of every 100, which is a sampling rate of 1 in 2, a NetFlow sampler must be configured. The `sampler SAMPLER-1` command initiates the configuration of a named sampler where the sampling mode and rate (e.g., `mode random 1 out of 2`) would be defined, and then applied to an interface.
