Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 201

Which application should be used to externally access all applications deployed in the same host machine with a single public IP address and port, when each application listens on different local ports?

Answer options

• A. reverse proxy
• B. load balancer
• C. DNS
• D. firewall

Correct answer: A

Explanation

A reverse proxy is designed to route incoming traffic to the appropriate application based on the requested URL or other criteria, making it ideal for this scenario. A load balancer distributes traffic across multiple servers and does not specifically handle port mapping for applications. DNS is used for resolving domain names to IP addresses and does not manage traffic routing. A firewall controls access to a network but does not facilitate application access through port mapping.
