    Nice quiz but I have few doubts in some of the questions:-
    Q5) The namenode loses its only copy of fsimage file. We can recover this from which of the following?
    Ans as per Dataflair)- It can’t be recovered
    Doubt) – Secondary namenode is also present as one of the options and we can recover fsimage from there then why the answer is “It can’t be recovered”?

    Q12) Which of the following is the core component of HDFS
    Ans as per Dataflair) DataNode
    Doubt) Its correct answer is NameNode I think because lets assume that even if a DataNode fails then we can still recover its data from other nodes but if we have only one Namenode and this also fails then our complete cluster will go down for some time.
    Therefore NameNode is the correct answer as per my knowledge.

    I may be wrong so please clear my doubts if I am wrong.
