Hello,

 

one of the risks in the 'Before' picture is that you seem to have two networks separated by a router, possibly for the purpose of access control, and those same two networks connected by a layer 2 (switch) link. In theory, either one user on these networks could just change their IP address to an address of the respective other network, and they would have full access. So you might want to get rid of the "inter-switch" link altogether.

 

In the 'After' picture, it looks like three different countries are connected in a "daisy-chained" topology, which means if 'Spain' goes down, all connectivity between all countries goes down. So 'Spain' is a single point of failure. To mitigate this, either backup links or a full mesh between countries would be an option.

The risk I see is someone who is happy to "copy-n-paste" someone else's work. 

CCNP stands for Certified Copy-N-Paste.

hello Georg Pauwen, very nice response here. thank you very much. lets dwell more on the after picture.

is there a problem in configuration just by the look of the picture. first of all, the red arrows are pointing towards one direction. can this be a problem? and if yes what risk does it pose

 

Hello,

 

I think the red arrows just mean that the link is down. Every link marked with a red arrow is a single link with no redundancy.

 

I am not sure if this is all they are looking for though. What is the context of this question ? Is that an exam question (with multiple choice answers) ?
