[@pramodmohanty4909]

C

[@ajaymaninder528]

Option (c ). Explanation : the advantage of the 3x replication schema in HDFS is to ensure fault tolerance(because the data will be stored in multiple systems and the data will not be lost even if one of the data node is crashed or lost in a system as it has multiple copies).

[@jwuhome]

@@SimplilearnOfficial What if you lost 3 nodes at the same time? ie: power lost in one rack(I know it's a bad layout)?

[@GlobusTheGreat]

@@jwuhome Then you're screwed and your replication didn't help and that data is inaccessible or lost. But the whole idea is that any one machine has a very low chance of failure, individually. But with thousands of machines, the event of *any* machine failing becomes more frequent and expected. But the chance of the 3 specific machines that house all the replicas for some block of data *simultaneously* failing is basically miniscule. The only way to lose data is for each node to fail within the time it takes to re-replicate the data (after losing one node, it will replicate the block again somewhere else to maintain 3 replicas). Replication is pretty quick. Let's say it takes 1 minute to replicate a node (probably much quicker than that), and any node has a 0.01% chance to fail over the course of any given minute (totally arbitrary, I'm not sure at all, but it's probably significantly less than that). Then within that 1 minute it would require the other 2 replicas to fail. So if you already assume that the first node failed, there would only, in this example, 0.0001% chance of actual data loss. That's one in a million failures causing data loss. You might already understand this, in which case the problem is evident in your question: replicas should be spread out such that their failures are independent events, rather than together on a rack where they could all fail and cause data loss.

[@cristubek2416]

Did he won the prize?? LOL

[@pawansapkota3970]

@@GlobusTheGreat aren't these server running on commodity hardware ? If so won't the chance of them failing is inevitable. I read the google's paper on GFS where they said hardware failure is assumed to happen. And HDFS is based on GFS( PS: I am new to big data )

Answer is at least a, b, c and could include d, depending on how you define manage. Yes 3x replication ensures fault tolerance but it also allows parallel execution of jobs to be placed on the same node where a block of data resides. The locality benefit can provide faster data analysis and efficient cluster management depending on the workloads.

Big Data is not unstructured data as you might have suggested in the beginning. Big Data is around big data sets that are otherwise too large to deal with. Big Data might be generated by a particle accelerator, for example, it will be structured data but will be considered as 'Big Data'. By the way, this term is not commonly used by Data professionals. It's mostly used by managers and marketing people.

The answer would be (C) Ensures Fault Tolerance! Thanks again. Wonderful presentation

[@SimplilearnOfficial]

"You've got the The correct answer is option C. The advantage of the 3x replication schema in HDFS is to Ensure fault tolerance. When one block is created, it is replicated with a replication factor of 3 and it is stored on the racks of different DataNodes. By doing so, data is not lost at any cost; even if one DataNode crashes, hence HDFS is fault-tolerant."
