Question

Which of the following is true for proxy firewalls?

• A. They increase data transfer rate.
• B. They slow down data transfer rate.
• C. They do not perform deep packet inspection.
• D. They do not hide identity and location of internal devices.

Hint:

Proxy firewalls provide enhanced security but can reduce network speed due to deep inspection.

Answer 1

The Correct Option is B

Proxy firewalls act as intermediaries between end-users and the internet by inspecting and filtering data packets. Because they analyze and process data in detail, proxy firewalls introduce additional overhead, which often results in slower data transfer rates compared to simpler firewall types. Other options explained:

• Proxy firewalls do not increase data transfer rates.
• They do perform deep packet inspection to enhance security.
• Proxy firewalls do hide the identity and location of internal devices by acting as intermediaries.
