Exam TK0-201 topic 4 question 47 discussion

An analogy is used when you're looking to compare to things in similarity. Analogies are used when someone needs an elaboration of an idea that they're unfamiliar with, and you need to find a way for them to be able to visualize the topic, i.e. when explaining things like explaining "sharding" in data engineering. People don't understand how resharding works, but if you explain it's like having a 10 lane highway that can't accommodate rush hour traffic, so the city opens up additional HOV lanes to accommodate for more traffic. Sharding is similar- when you want to increase the flow of data in streams, you use what's called sharding to add more streams... very much like how the city opens HOV traffic lanes in the direction of rush hour traffic to keep the traffic moving. THAT is an analogy. If someone can explain why an analogy is supposed to be anything other than that, I'd like to hear it. Weird.
