A user is on a wired connection and the posture status is noncompliant. Which state will their EPS session be placed in?

You will have forty-eight failed task attempts You will have seventeen failed task attempts You will have five failed task attempts You will have twelve failed task attempts You will have twenty failed task attempts

2.

In Cisco ISE, which probe must be enabled to collect profiling data using Device Sensor?

combine map init configure

3.

Which statement about Cisco ISE BYOD is true?

Combiner OutputFormat WritableComparable Writable InputFormat

4.

Which protocol sends authentication and accounting in different requests?

SequenceFiles Avro JSON HTML XML

5.

You enabled the guest session limit feature on the Cisco ISE. However, end users report that the same guest can log in from multiple devices simultaneously. Which configuration is missing on the network access device?

64 100 200 640

6.

A properly configured Cisco ISE Policy Service node is not receiving any profile data from a Cisco switch that runs Device Sensor. Which option is the most likely reason for the failure?

As soon as at least one mapper has finished processing its input split. As soon as a mapper has emitted at least one record. Not until all mappers have finished processing all records. It depends on the InputFormat used for the job.

7.

A network administrator needs to implement a service that enables granular control of IOS commands that can be executed. Which AAA authentication method should be selected?

The client queries the NameNode for the block location(s). The NameNode returns the block location(s)

to the client. The client reads the data directory off the DataNode(s). The client queries all DataNodes in parallel. The DataNode that contains the requested data respondsdirectly to the client. The client reads the data directly off the DataNode. The client contacts the NameNode for the block location(s). The NameNode then queries theDataNodes for block locations. The DataNodes respond to the NameNode, and the NameNode redirects the client to the DataNode that holds the requested data block(s). The client then reads the data directly off the DataNode. The client contacts the NameNode for the block location(s). The NameNode contacts the DataNodethat holds the requested data block. Data is transferred from the DataNode to the NameNode, and then from the NameNode to the client.

8.

An administrator can leverage which attribute to assign privileges based on Microsoft Active Directory user groups?

Intermediate data in streamed across the network from Mapper to the Reduce and is never written to disk. Into in-memory buffers on the TaskTracker node running the Mapper that spill over and are written intoHDFS. Into in-memory buffers that spill over to the local file system of the TaskTracker node running theMapper. Into in-memory buffers that spill over to the local file system (outside HDFS) of the TaskTracker noderunning the Reducer Into in-memory buffers on the TaskTracker node running the Reducer that spill over and are written intoHDFS.

9.

Cisco 802.1X phasing enables flexible deployments through the use of open, low-impact, and closed modes. What is a unique characteristic of the most secure mode?

Ingest the server web logs into HDFS using Flume. Write a MapReduce job, with the web servers for mappers, and the Hadoop cluster nodes for reduces. Import all users' clicks from your OLTP databases into Hadoop, using Sqoop. Channel these clickstreams inot Hadoop using Hadoop Streaming. Sample the weblogs from the web servers, copying them into Hadoop using curl.

10.

A network administrator must enable which protocol extension to utilize EAP-Chaining?

Single point of failure in the NameNode. Resource pressure on the JobTracker. HDFS latency. Ability to run frameworks other than MapReduce, such as MPI. Reduce complexity of the MapReduce APIs.
