ENSA Module 8 -- Final Exam Prep, VPN and IPSec

What is the primary difference between TLS and SSL protocols?

• TLS is easier to deploy but less secure than SSL.

• SSL is the newer version of TLS.

• TLS is the newer version of SSL and is more secure.

• SSL is used for encryption, while TLS is not.

Which security protocol do remote access VPNs use to encrypt data over the Internet?

• TLS/SSL

• IPSec

• POP3

• SMTP

• FTP/SFTP

Which of the following is a characteristic of a Remote-Access VPN?

• It requires special client software installed on the user's device.

• It connects two company branch offices.

• It uses a router configured with VPN software.

• It does not require any client software.

What is the role of IPSec in a GRE over IPSec VPN?

• It provides a non-secure tunneling protocol.

• It encrypts the data to create a secure VPN tunnel.

• It is used for multicast and broadcast traffic.

• It routes packets through virtual tunnel interfaces.

Which VPN type is described as using labels to distribute packets between routers?

• GRE over IPSec

• DMVPN

• MPLS VPN

• IPSec VTI

What is a key feature of Dynamic Multipoint VPNs (DMVPN)?

• It uses a point-to-point configuration.

• It requires a separate GRE interface for each connection.

• It supports multicast and broadcast traffic with a hub and spoke configuration.

• It does not support full mesh topology.

Which of the following is true about IPSec VTI?

• It uses GRE for encryption.

• It routes packets through virtual tunnel interfaces without the overhead of GRE.

• It is a proprietary protocol.

• It does not provide confidentiality services.

What is the purpose of Cisco's "AnyConnect" software?

• It is used for configuring routers in a Site-to-Site VPN.

• It is a client software for Remote-Access VPN connections.

• It is used to distribute labels in MPLS VPNs.

• It is a protocol for encrypting data in GRE tunnels.

Which protocol provides confidentiality, integrity, and authentication services in VPNs?

• GRE

• SSL

• IPSec

• MPLS

What is the main advantage of using a Site-to-Site VPN over a Remote-Access VPN?

• It requires client software on each user's device.

• It allows users to connect from any location.

• It is transparent to the user and connects entire networks.

• It is easier to deploy than Remote-Access VPNs.
