What kind of protection does a DMZ provide?

A DMZ, or demilitarized zone, serves as a critical security architecture element by isolating external-facing services from the internal network. This isolation mitigates the risk of external threats, such as attacks from untrusted sources on the internet, accessing the core and sensitive resources of an organization's internal network.

In practice, a DMZ typically hosts servers that are exposed to the internet, such as web servers, mail servers, and DNS servers. By placing these services in a DMZ, organizations can enhance their security posture, allowing external users to access only these specific resources while keeping the rest of the internal network free from direct exposure.

This architecture allows for the implementation of stringent security measures, like firewalls, to control traffic between the DMZ and both the external world and the internal network, ensuring that even if a service in the DMZ is compromised, attackers still have limited access to the organization’s internal assets.

The other options don't apply to the direct function of a DMZ. For instance, encryption of data traffic is typically handled by different protocols and does not inherently involve a DMZ configuration. Similarly, a DMZ does not speed up data transmission; rather, it serves a protective purpose. Moreover, creating a DMZ
