Cloudera CCA-505 考試大綱主題:

最新的 CCAH CCA-505 免費考試真題：

問題 #1

You decide to create a cluster which runs HDFS in High Availability mode with automatic failover, using Quorum-based Storage. What is the purpose of ZooKeeper in such a configuration?

A. It manages the Edits file, which is a log changes to the HDFS filesystem.
B. Clients connect to ZoneKeeper to determine which NameNode is Active
C. It monitors an NFS mount point and reports if the mount point disappears
D. It only keeps track of which NameNode is Active at any given time
E. It both keeps track of which NameNode is Active at any given time, and manages the Edits file, which is a log of changes to the HDFS filesystem

問題 #2

You have a Hadoop cluster running HDFS, and a gateway machine external to the cluster from which clients submit jobs. What do you need to do in order to run on the cluster and submit jobs from the command line of the gateway machine?

A. Install the impalad daemon on each machine in the cluster, the statestored daemon and catalogd daemon on one machine in the cluster, and the impala shell on your gateway machine
B. Install the impslad daemon, statestored daemon, and catalogd daemon on each machine in the cluster and on the gateway node
C. Install the impalad daemon and the impala shell on your gateway machine, and the statestored daemon and catalog daemon on one of the nodes in the cluster
D. Install the impalad daemon, statestored daemon, and catalogd daemon on each machine in the cluster, and the impala shell on your gateway machine
E. Install the impalad daemon, the statestored daemon, the catalogd daemon, and the impala shell on your gateway machine

問題 #3

You are migrating a cluster from MapReduce version 1 (MRv1) to MapReduce version2 (MRv2) on YARN. To want to maintain your MRv1 TaskTracker slot capacities when you migrate. What should you do?

A. Configure yarn.applicationmaster.resource.memory-mb and yarn.applicationmaster.cpuvcores so that ApplicationMaster container allocations match the capacity you require.
B. You don't need to configure or balance these properties in YARN as YARN dynamically balances resource management capabilities on your cluster
C. Configure mapred.tasktracker.map.tasks.maximum and mapred.tasktracker.reduce.tasks.maximum ub yarn.site.xml to match your cluster's configured capacity set by yarn.scheduler.minimum-allocation
D. Configure yarn.nodemanager.resource.memory-mb and yarn.nodemanager.resource.cpu-vcores to match the capacity you require under YARN for each NodeManager

問題 #4

You are planning a Hadoop cluster and considering implementing 10 Gigabit Ethernet as the network fabric. Which workloads benefit the most from a faster network fabric?

A. When your workload generates a large amount of output data, significantly larger than amount of intermediate data
B. When your workload generates a large amount of intermediate data, on the order of the input data itself
C. When workload consumers a large amount of input data, relative to the entire capacity of HDFS
D. When your workload consists of processor-intensive tasks

問題 #5

On a cluster running CDH 5.0 or above, you use the hadoop fs -put command to write a 300MB file into a previously empty directory using an HDFS block of 64MB. Just after this command has finished writing 200MB of this file, what would another use see when they look in the directory?

A. They will see the file with a ._COPYING_extension on its name. If they attempt to view the file, they will get a ConcurrentFileAccessException until the entire file write is completed on the cluster.
B. The directory will appear to be empty until the entire file write is completed on the cluster
C. They will see the file with its original name. if they attempt to view the file, they will get a ConcurrentFileAccessException until the entire file write is completed on the cluster
D. They will see the file with a ._COPYING_ extension on its name. if they view the file, they will see contents of the file up to the last completed block (as each 64MB block is written, that block becomes available)
