Exam DEA-1TT4 topic 1 question 64 discussion

The question talk about "maximum 1 ISL", then the answer correct is "Partial mesh topology"

The correct answer is A The question mentions 4 switches, maximum of one Hop and is for localized compute-to-storage traffic. In a full mesh, every switch is connected to every other switch in the topology. A full mesh topology may be appropriate when the number of switches that are involved is small. A typical deployment would involve up to four switches or directors, with each of them servicing highly localized compute-to-storage traffic. In a full mesh topology, a maximum of one ISL or hop is required for compute-to-storage traffic.

Think the wording is a bit confusing here. I think by 1 ISL is means only one ISL between compute to storage. So basically one hop. " a maximum of one ISL or hop is required for compute-tostorage traffic"

thanks already check the answer is A

Answer is A. Page 319 of the official material. A full mesh topology may be appropriate when the number of switches that are involved is small. A typical deployment would involve up to four switches or directors, with each of them servicing highly localized compute-to-storage traffic. In a full mesh topology, a maximum of one ISL or hop is required for compute-tostorage traffic.

I do not agree with the answer since in the Full mesh topology each switch has more than one ISL connected
