Câu 70: 300-730: Implementing Secure Solutions with Virtual Private Networks (SVPN 300-730)

A network engineer is implementing a FlexVPN tunnel between two Cisco IOS routers. The FlexVPN tunnels will terminate on encrypted traffic on an interface configured with an IP MTU of 1500, and the company has a security policy to drop fragmented traffic coming into or leaving the network. The tunnel will be used to transfer TFTP data between users and internal servers. When the TFTP traffic is not traversing a VPN, it can have a maximum IP packet size of 1500. Assuming the encrypted payload will add 90 bytes, which configuration allows TFTP traffic to traverse the FlexVPN tunnel without being dropped?

1. A. Set the tunnel IP MTU to 1500.
