A. B. C. D.D
An example of IPsec site-to-site VPN is your corporation has departments in many countries which need to communicate with each other. A popular solution is site-to-site (LAN-to-LAN) VPN to create private networks through the Internet. But as we know, Internet is not a safe environment for important data to be transferred. That is the reason why we need IPsec, a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session.
Cisco Adaptive Security Appliance (ASA) supports IPsec, thats all I can say! If you wish to learn more about the configuration, please read http://www.cisco.com/ en/US/products/ps5855/products_configuration_example09186a0080a9a7a3.shtml
The device that might be installed at a branch office to enable and manage an IPsec site-to-site VPN is the Cisco Adaptive Security Appliance (ASA).
The Cisco ASA is a security device that provides firewall, VPN, and other security services. It is commonly used in enterprise networks to provide secure remote access and site-to-site VPN connectivity. The ASA supports both IPsec and SSL VPNs, making it a versatile choice for securing branch office connections.
The Cisco IOS IPsec/SSL VPN client is a software application that runs on a computer or mobile device, allowing it to connect to a VPN. However, it is not a device that can be installed at a branch office.
The Cisco VPN Client is another software application that allows a computer to connect to a VPN, but it is no longer supported by Cisco and has been replaced by newer VPN technologies.
An ISDN terminal adapter is a device that connects a computer or other network device to an ISDN line. It is not used for VPN connectivity.
Therefore, the correct answer is D. Cisco Adaptive Security Appliance.
