Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 81

What is the purpose of a firewall in application deployment?

Answer options

• A. adds TLS support to an application that does not support it natively
• B. limits traffic to only ports required by the application
• C. provides translation for an application's hostname to its IP address
• D. forwards traffic to a pool of instances of the application

Correct answer: B

Explanation

The correct answer is B because a firewall is designed to manage and control incoming and outgoing network traffic based on predetermined security rules, specifically limiting traffic to only those ports that the application requires. Options A, C, and D describe functions that are not the primary purpose of a firewall, such as adding TLS support or handling hostname translations.
