Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 461

An existing application is accessible from an external IP address. Which device or service must be configured to make the application accessible through a URL by using a domain name?

Answer options

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

Correct answer: B

Explanation

The correct answer is B, DNS, because it translates domain names into IP addresses, allowing users to access applications using friendly URLs. The other options, such as reverse proxy, firewall, and load balancer, serve different purposes such as traffic management and security, but do not directly handle the mapping of domain names to IP addresses.
