CCSP · Question #340

A truly airgapped machine selector will ____________. Response:

The correct answer is A. Terminate a connection before creating a new connection. An airgapped machine selector ensures strict isolation by terminating any existing connection before establishing a new one, preventing data leakage between connected systems.

Why each option

An airgapped machine selector ensures strict isolation by terminating any existing connection before establishing a new one, preventing data leakage between connected systems.

ATerminate a connection before creating a new connectionCorrect

A truly airgapped machine selector, often used for KVM switches in high-security environments, is designed to physically and logically isolate connected machines. This means it must completely disconnect from one machine (terminate the connection) before initiating a connection to another, ensuring no shared data path or concurrent access.

BBe made of composites and not metal

The material composition (composites vs. metal) is generally irrelevant to the airgap principle of connection isolation.

CHave total Faraday properties

While isolation is key, 'total Faraday properties' relate to electromagnetic shielding and are not the primary defining characteristic of an airgapped machine selector's operational mechanism.

DNot be portable

Portability is not a defining characteristic of an airgapped system; the core concept is isolation, regardless of whether it can be moved.
