The choice indicating that it is necessary to have at least two Nessus scanners behind the firewall is not correct because there is no mandatory requirement in Nessus deployment that dictates the need for a specific number of scanners behind a firewall. The actual number of scanners needed can vary based on the networking architecture, the volume of assets to be scanned, and organizational policies.

A primary aspect of Nessus scanners' configuration is their ability to interact with the targets being assessed, ensuring that they can communicate adequately while maintaining security protocols. For many setups, a single scanner can function effectively behind a firewall, depending on the size and complexity of the network and the specific requirements of the scanning process.

In scenarios where enhanced performance is needed, deploying multiple scanners can help distribute the load and decrease the time it takes to complete network scans, which aligns with the understanding of network efficiency. However, the number of necessary scanners should be guided by the specific requirements of the environment rather than a set rule that states two scanners must be used.

Thus, the assessment of scanner deployment should consider operational needs rather than adhering to a strict two-scanner rule.
