What is the primary purpose of implementing a site-to-site VPN between Branch A and Branch B?

• To enhance internet speed for users at both locations.

• To establish a secure and private connection between the two branch offices over the internet.

• To bypass geo-restrictions imposed by the local authorities.

• To replace the physical network cables between the branches.

Which IPsec protocol offers data confidentiality, integrity, and authentication services by encrypting the entire data payload of IP packets?

• AH (Authentication Header)

• ESP (Encapsulating Security Payload)

• IKE (Internet Key Exchange)

• GRE (Generic Routing Encapsulation)

What are the benefits of using a site-to-site VPN?

• Enhanced security, data privacy, and bypassing geo-restrictions.

• Faster internet speed and remote access for users.

• Increased productivity for remote workers and secure data transfer.

• Anonymous online activities and improved network reliability.

How does a VPN achieve data confidentiality between the user's device and the VPN server?

• By using Network Address Translation (NAT) to hide the user's IP address.

• By providing data integrity and authentication services using the AH protocol.

• By encrypting the data transmitted over the internet using encryption protocols like ESP.

• By creating a private subnet for the user's device within the public network.

Which type of VPN is commonly used by remote workers or travelers who need to securely access company resources from outside the office?

• Site-to-Site VPN
