How will traffic that does not match that defined by access list 101 be treated by the router? Which statement accurately describes a characteristic of IPsec? VPNs use logical connections to create public networks through the Internet. IPsec is a framework of proprietary standards that depend on Cisco specific algorithms. VPNs use open source virtualization software to create the tunnel through the Internet. During the second phase IKE negotiates security associations between the peers. How to find: Press “Ctrl + F” in the browser and fill in whatever wording is in the question to find that question/answer. 22. While preventing brute-force attacks and other forced decryption concerns, the longer the key length, the harder it is to break. The device doing the VPN initiation offers the acceptable transform sets in order of preference, in this case, ESP authentication using DES for encryption or ESP authentication using SHA-HMAC authentication and integrity for the data payload. Multiple crypto ACLs can define multiple remote peers for connecting with a VPN-enabled router across the Internet or network. The correct syntax of the crypto isakmp key command is as follows: Integrity – IPsec ensures that data arrives unchanged at the destination using a hash algorithm, such as MD5 or SHA. Which transform set provides the best protection? Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco that encapsulates multiprotocol traffic between remote Cisco routers, but does not encrypt data. Multiple crypto ACLs are used to define multiple different types of traffic and utilize different IPsec protection corresponding to the different types of traffic. Different encryption algorithms will provide varying key lengths for implementation. RSA is an algorithm used for authentication. 14. Secure key exchange – IPsec uses the Diffie-Hellman (DH) algorithm to provide a public key exchange method for two peers to establish a shared secret key. Which type of site-to-site VPN uses trusted group members to eliminate point-to-point IPsec tunnels between the members of a group? MPLS and GRE are two types of Layer 3 VPNs.
