Which scanner can simultaneously perform two or more scans on different machines in the network?

• A. Proxy Scanner
• B. Nessus Professional
• C. GFI LanGuard
• D. OpenVAS

Answer: (A)

The idea being tested is parallel, multi-target scanning through proxies. A proxy scanner is designed to route each target’s scan through separate proxy hosts, so the tool can start and manage multiple scan sessions at the same time. This lets you assess several machines in one pass, across different network paths or segments, without waiting for one scan to finish before starting another. It’s especially useful in networks with ACLs or segmentation, where using multiple proxies or proxy paths enables concurrent coverage.

Other scanners can indeed handle many targets, but their typical mode is a single scan engine evaluating many hosts rather than explicitly dispatching simultaneous scans through distinct proxies. The proxy-scanner setup directly supports true parallelism across multiple machines via separate proxies, making it the best fit for performing two or more scans concurrently.
