What is the difference between permanent nodes and edge nodes?

• A.Permanent nodes contain you Hadoop data, but edge nodes do not have Hadoop data.
• B.Permanent nodes cannot be stopped, whereas you can start and stop edge nodes.
• C.Permanent nodes are for the life of the cluster, whereas edge nodes are temporary for the duration for processing the data.
• D.Permanent nodes contain you Hadoop data, but edge nodes give you the "edge" in processing you r data with more processors.

A company is using Oracle Big Data Cloud Service that has Hive- tables owned by user A.
The tables are being dropped by user B . How should you Implement authorization In Hadoop?

• A.Implement role based security using sentry.
• B.Configure Apache Record Service.
• C.Implement role based security using Kerberos.
• D.Hole-based separation is not possible because Hadoop is a file system.

A financial company uses Hadoop cluster to store, process, and analyze all the stock trading data. They use a map reduce job to generate daily reports for their clients by 6 a.m. every using the data on adoop cluster. One of the data nodes in the cluster crashed due to hard disk failure.
What will be the impact?

• A.Restore the data from backup to the new node and rerun the report
• B.Downtime will be needed to replace the failed hard disk and rerun the report
• C.Hadoop can reboot the tailed node automatically and rectify the faulty dink.
• D.HDFS replication factor ensured that report generation process runs to completion

You need to enforce network encryption, as Kerberos Authentication does, not protect data as it travels through the network. Hadoop being a distributed system means that data must be transmitted over the network across machines.
Which is NOT a network communication protocol used for network encryption?

• A.SSL
• B.Hadoop RPC
• C.Direct TCP/IP
• D.HTTPS

When you create a cluster with Security Setup enabled, HDFS Transparent Encryption is enabled on the cluster, and MIT Kerberos, Sentry, Network Firewall, Network Encryption, and Auditing are also enabled on the cluster.
Which two principals are created as part of the Kerberos configuration?

• A.oracle/[email protected]
• B.hdfs/[email protected]
• C.oracle/[email protected]
• D.hdfs/[email protected]
