最新的 CCAH CCA-410 免費考試真題:

1. You set up the Hadoop cluster using NameNode Federation. One NameNode manages the/users namespace and one NameNode manages the/data namespace. What happens when client tries to write a file to/reports/myreport.txt?

A) The client throws an exception.
B) The file successfully writes to /report/myreport.txt. The metadata for the file is managed by the first NameNode to which the client connects.
C) The file writes fails silently; no file is written, no error is reported.
D) The file successfully writes to /users/reports/myreports/myreport.txt.

2. You are running two Hadoop clusters(cluster1 and cluster2), they run identical versions of hadoop.
You want to copy the data inside /home/foo/cluster1 to cluster2 into the directory /home/bar/
What is the correct distcp syntax to copy one directory tree from one cluster to the other cluster?

A) $ distCp cluster1:/home/foo cluster2:/home/bar/
B) $ distCp hdfs://cluster1/home/foo hdfs://cluster2/home/bar/
C) $ Hadoop distCp cluster1:/home/foo cluster2:/home/bar/
D) $ hadoop distCp hdfs://cluster1/home/foo hdfs://cluster2/home/bar/

3. A client application opens a file write stream on your cluster. Which two metadata changes occur during a file write?

A) the change is written to the secondary namenode
B) the change is written to the fsimage file
C) The metadata in a Ram on the name node is updated
D) The change is written to the namenode disk
E) The change is written to the edits file
F) the metadata in Ram on the namenode is flushed to disk
G) the namenode triggers a block report to update block locations in the edits file

4. What additional capability does Ganglia provide to monitor a Hadoop?

A) Ability to monitor the amount of free space on HDFS.
B) Ability to monitor free task slots.
C) Ability to monitor NameNode memory usage.
D) Ability to monitor number of files in HDFS.
E) Ability to monitor processor utilization.

5. Once a client application validates its identity and is granted access to file in a cluster. What is the reminder of read path back to the client?

A) the namenode maps the read request against the block locations in its stored metadata and reads those blocks from the datanodes. The client applications then read the block from the namenode
B) The namenode maps the read request against the block locations in it's stored metadata the block id's are stored by their distance to the client and moved to the datanode closest to the client according to hadoop rac topology. The client application then reads the blocks from the single datanode
C) The namenode gives the client the block ID's and a list of Datanodes on which those blocks are found. And the application reads the block directly from the datanodes
