A company wants to connect two branch offices over the internet. They need strong encryption, support for both IPv4 and IPv6, and the ability to use certificates for device authentication. Which VPN protocol best fits these requirements?

WireGuard with pre-shared keys only

SSL/TLS VPN using a web browser

IPsec with IKEv2 and certificate-based authentication

In the context of VPNs, what does tunneling do to the original data packet?

It compresses the packet to reduce its size

It deletes the original packet and creates a new one with the same content

It encrypts the packet and then encapsulates it in a new packet with a new header

It changes the destination IP address to the VPN server's address

A school district wants to enforce web filtering on student devices, block access to social media during class hours, and log all web requests for compliance. They also want to reduce bandwidth usage by caching frequently visited educational sites. Which proxy function combination best meets these needs?

Content filtering and access control with caching

Network address translation and port forwarding

Anonymity and encryption with load balancing

Reverse proxy with SSL termination
