Eccouncil 312-38 Exam - Topic 9 Question 24 Discussion

Agreed, managing security keys is crucial for VPNs!

No way it provides access memory, that sounds off.

I thought it only handled tunnels, surprised it does more.

Definitely assigns user addresses!

It also manages security keys, right?

I don't think they provide access memory or handle I/O operations, but I'm not 100% confident on that.

I practiced a question similar to this, and I feel like managing security keys is definitely a function, but I can't recall the others clearly.

I think they also assign user addresses, but I might be mixing it up with DHCP functions.

I remember something about VPN concentrators managing security keys, but I'm not entirely sure if that's the only function.

Hmm, I'm not sure about this one. The catalog seems like the obvious choice, but could the CMDB also contain relevant information? I'll have to think this through carefully.

Okay, I think I've got a handle on this. The analyst said the web page design mainly influenced high income people, so I'll need to look for a graph that shows a clear difference in intent to purchase between the income groups for the different web page designs.

The key here is communication and information sharing. Sharing demand data across the supply chain is the best way to ensure supply and demand are aligned. The other options don't address that core issue.

Answer should be B and D. Functions of a VPN Concentrator A VPN concentrator adds more security controls to the router, improving the security of the communication. The functions of a VPN concentrator are as follows: ? Data encryption: The VPN concentrator encrypts the data. Being bi-directional, it initially encrypts the plain packets it receives and later decrypts them at the end of the tunnel before sending them to the destination. ? Managing tunnels: By adding the features of advanced data and network security, a VPN concentrator has the ability to create and manage large VPN tunnels. These tunnels ensure data integrity among the systems. ? User Authentication: A VPN concentrator authenticates users at either the computer level or at the user level. Authentication at the computer level takes place using the Layer Two Tunneling Protocol (L2TP) protocol whereas authentication at the user level takes place using the Point-to-Point Tunneling Protocol (PPTP). ? Traffic handler: A VPN concentrator routes the tunneled and non-tunneled traffic depending on the server configuration. It simultaneously handles traffic of a corporate network as well as Internet resources
