A circuit level proxy is ____________ when compared to an application level proxy.
Correct Answer: A
Explanation/Reference:
Explanation:
A circuit level proxy works at the session layer of the OSI model and monitors traffic from a network-based view. This type of proxy cannot "look into" the contents of a packet like an application level proxy; thus, it does not carry out deep-packet inspection. This means that, compared to an application level proxy, A circuit level proxy is faster.
Incorrect Answers:
B: A circuit level proxy is easier to maintain as it is less flexible.
C: A circuit level proxy is less secure since it only works at the session layer, and cannot inspect data packets.
D: A circuit level proxy is faster, not slower.
