Explanation
The cause of the connection issue is a routing loop. A routing loop is a situation where a packet is forwarded in circles between routers, never reaching its destination. A routing loop can be caused by misconfigured or inconsistent routing tables, or by routing protocols that do not update their information properly. A routing loop can be detected by using the traceroute command, which shows the path taken by a packet from the source to the destination. The traceroute output in the image shows that the packet is bouncing back and forth between two routers, 10.12.2.1 and 10.12.2.2, indicating a routing loop.

IaaS is the better answer because DaaS require compatible devices thus the scalability is proportional to the availability of these devices. IaaS on the other hand is servers and one can scale those up in the background with just a click of the mouse.

The U.U.U.U is suppose to be 0.0.0.0 and A route when no other route matches.
The "gateway of last resort" meaning it needs a DG address.

"Baselines play an integral part in network documentation because they let you monitor the network's overall performance. In simple terms, a baseline is a measure of performance that indicates how hard the network is working and where network resources are spent. The purpose of a baseline is to provide a basis of comparison.
For example, you can compare the network's performance results taken in March to results taken in June, or from one year to the next. More commonly, you would compare the baseline information at a time when the network is having a problem to information recorded when the network was operating with greater efficiency.
Such comparisons help you determine whether there has been a problem with the network, how significant that problem is, and even where the problem lies."

2.4GHz frequency has better penetration and range than higher frequencies in forested environments, where there are many obstacles and interference sources.
