A network technician is designing a network for a small company. The network technician needs to implement an email server and web server that will be accessed by both internal employees and external customers. Which of the following would best secure the internal network and allow access to the needed servers? A. Implementing a site-to-site VPN for server access. B. Implementing a DMZ segment for the server. C. Implementing NAT addressing for the servers. D. Implementing a sandbox to contain the servers.

Option A (Implementing a site-to-site VPN for server access) seems to be the correct choice.

Explanation:

A site-to-site configuration is something that a single Open VPN network links several more separate networks linked. Technologies through one network will access machines in all the other computer systems in that connection model, including conversely. Implementing this would be extremely straightforward, for as much further even though Access Server was indeed implicated.The much more challenging aspect happens when interacting regarding firewalls including privacy filtering methods, as well as modifying the forwarding table in internet gateways, as several of them from different manufacturers but instead prototypes which they may not be able to log many of these.This rather gateway device uses an Open VPN with a Linux VPN client, to create a connection between various channels. If someone's server hardware is also measured accurately then perhaps a site-to-site configuration could be accomplished which works straightforwardly throughout all systems in both cable systems.

Other choices are not related to the given instance. So that Option A would be the right one.
