Which process is used to protect transmitted data in a VPN?
Answer: a) Tunneling
The need for secure data transmission is paramount in today’s digital world, and virtual private networks (VPNs) are an essential tool to ensure privacy and security. But there arise a question about the process which is used to protect transmitted data in a VPN.
To answer this question, let’s take a look at the five most common processes: Tunneling, Point-to-Point Protocol (PPP), Voice over Internet Protocol (VoIP), Packet Switching, and Chaining.
PPP works similarly by creating point-to-point connections between two computers or servers using special protocols such as IPsec or L2TP/IPSec protocol suites for authentication purposes before allowing any communication between them takes place over a public network like the internet without being intercepted by third parties along its path from source computer A going towards computer B .
VoIP allows users with compatible devices such as smartphones connected via WiFi hotspots share voice conversations across long distances without compromising their privacy due The encryption methods employed when transmitting audio signals make sure no one can listen in on what you're saying even if they intercept packets traveling back forth from sender receiver endpoints respectively.
Packet switching helps facilitate efficient delivery of messages sent out over different paths , meaning if one route becomes blocked then another alternative route could potentially exist depending upon how many nodes have been set up within given network infrastructure structure itself enabling greater flexibility when sending large amounts transmissions simultaneously while also helping reduce latency issues associated with traditional circuit switching techniques due lack having dedicated connection setup prior initiating transfer operations themselves.
Lastly, chaining involves connecting multiple tunnels together create longer more secure pathways than single ones would allow thereby providing extra layers protection against potential eavesdroppers attempting gain unauthorized access sensitive information contained therein making less likely successful attack attempts occur successfully since there multiple checkpoints must passed order reach desired endpoint thus increasing overall security levels significantly compared other options mentioned above.
