Which IKEv2 feature minimizes the configuration of a FlexVPN on Cisco IOS devices?
Which IKEv2 feature minimizes the configuration of a FlexVPN on Cisco IOS devices?
IKEv2 Smart Defaults is a feature designed to minimize the configuration needed for setting up a FlexVPN on Cisco IOS devices. This feature pre-configures certain settings and options, reducing the amount of manual input required from the user. This can greatly simplify the process, making it quicker and less prone to configuration errors.
When you configure IPsec VPN High Availability Enhancements, which technology does Cisco recommend that you enable to make reconvergence faster?
Periodic IKE keepalives help in monitoring the availability of the IPsec peer and ensuring the VPN connection is alive. Cisco recommends enabling IKE keepalives to make reconvergence faster in VPN High Availability configurations. This method ensures that the VPN gateway can quickly detect a failure and initiate a reconvergence process to re-establish the tunnel with an alternate peer.
Which algorithm is replaced by elliptic curve cryptography in Cisco NGE?
In the context of Cisco's Next Generation Encryption (NGE), elliptic curve cryptography (ECC) is designed to replace traditional methods such as RSA and Diffie-Hellman (DH). These older methods are based on the difficulty of factoring large integers or the discrete logarithm problem, but ECC provides a higher level of security with smaller key sizes. Therefore, ECC is replacing RSA for better performance and security in Cisco NGE.
Which encryption and authentication algorithms does Cisco recommend when deploying a Cisco NGE supported VPN solution?
Cisco recommends using Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) for encryption and Secure Hash Algorithm 2 (SHA-2) for authentication when deploying a Cisco Next Generation Encryption (NGE) supported VPN solution. These algorithms provide stronger security and performance compared to older technologies.
An administrator wishes to limit the networks reachable over the Anyconnect VPN tunnels. Which configuration on the ASA will correctly limit the networks reachable to 209.165.201.0/27 and 209.165.202.128/27?
To limit the networks reachable over Anyconnect VPN tunnels to 209.165.201.0/27 and 209.165.202.128/27, the correct configuration involves using an access-list to define the specific networks and applying this access-list in the group-policy for the VPN connection. Specifically, option A correctly uses the 'access-list' command to permit the desired network ranges and the 'group-policy' command with 'split-tunnel-policy tunnelspecified' to define the split tunneling behavior and apply the access-list 'splitlist'.
