How does a VPN ensure that data transmitted over a public network remains confidential?

By using a dedicated physical line that cannot be intercepted

By encrypting the data before it enters the tunnel

By compressing the data to make it unreadable

By routing the data through multiple proxy servers

An administrator is deploying a forward proxy for employee internet access. The security team requires that the proxy authenticate users, log all web requests, and block malware domains. Which configuration best meets these requirements?

Enable TLS interception, disable logging, and use a reverse proxy

Enable NTLM or Kerberos authentication, enable access logging, and integrate with a threat-intelligence feed

Disable authentication for performance, log only errors, and use a static blocklist

Use anonymous access, enable full logging, and rely on client-side antivirus

What is the primary purpose of a Virtual Private Network (VPN)?

To create a secure, encrypted tunnel over a public network such as the internet

To increase the speed of internet connections by compressing data

To replace the need for a firewall on the local network

To provide a direct physical connection between two offices

A company is considering using a VPN to allow remote employees to access internal resources. However, they are concerned about the risk of malware being introduced through the VPN tunnel. Which additional control is most effective in mitigating this risk?

Use a stronger encryption algorithm

Increase the VPN timeout to keep connections alive longer

Implement endpoint security checks before allowing VPN connection (NAC)

Disable split tunneling to force all traffic through the VPN
