I found that some topics that are not given in link1 when compared with link2 are not same, such as sharding and replication. so, which link should I follow?
and also can you please share the exam guide that I should follow to prepare for the exam because there is so much inconsistency online?
I also had the same question. So, per the new exam guide, there is no replication, sharding related words. Is it safe to exclude them from the preparation? Please confirm. Thanks.
