Which technology would you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?
You are a network designer and have been asked to consult with your server operations team to further enhance the security of the network. The operations team provides you with these details about the network: . A pool of servers is accessed by numerous data centers and remote sites. ....
How would you redesign the network VPN headend devices to prevent this from happening again in the future?
A network administrator is in charge of multiple IPsec VPN headend devices that service thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power outage, in which it was found that a backup power supply in one of those headend devices was faulty, one of the headend routers suffered...
In which three ways should the design of the STP domain be optimized for server and application performance?
