E20-559 Exam Dumps | Traditional NAS storage architectures deploy

Questions: 12

Traditional NAS storage architectures deploy simple two-way failover between two controllers in storage systems, such as highly available configurations. How is the Isilon architecture different in terms of system resiliency and availability?

A. OneFS enables each node to have a designated partner node for simple failover between the pair.
B. Use of client-side drivers can enable failover to other nodes.
C. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
D. OneFS enables each node to be a peer to any other node in an Isilon cluster. Any node can take over for any other node.

Answer: A

Question: 11

An organization has an Isilon cluster with 15 S-S210 nodes in a single node pool and 20 NL400 nodes in a second node pool. They want to implement Global Namespace Acceleration. Which requirements must be achieved before Global Namespace Acceleration can be activated?

A. All S210 nodes must contain one SSD drive
SSD capacity must be at least 0.5% of the total cluster space
B. At least seven S210 nodes must contain at least one SSD drive
SSD capacity must be at least 1.5% of the total cluster space
C. All S210 nodes must contain at least one SSD drive
SSD capacity must be at least 2.25% of the total cluster space
D. All S210 nodes must contain at least one SSD drive
SSD capacity must be at least 20% of the total cluster space

Answer: B

Question: 10

If an Isilon has been integrated into an existing Hadoop environment, what explains how the HDFS data will be distributed?

A. HDFS data on Isilon and computations will be handled by Hadoop
B. HDFS data remains on Hadoop; computations is handled by Isilon
C. Files are stored in a specialized HDFS compatible file system format on the Isilon cluster
D. MapReduce on the Isilon allows data to be distributed across both platforms

Question: 9

What accurately describes the behavior of InsightIQ with FSA enabled on an Isilon cluster?

A. FSA job runs at 22:00 hours every night by default
B. Storage usage statistics will be less accurate
C. A separate FSA license is required
D. Total number of monitored nodes capacity is reduced by half

Answer: A

Question: 8

How is InsightIQ changed when FSA is enabled?

A. When enabled, a Job runs on the cluster and collects InsightIQ data
B. By default, it runs every hour and monitors cluster performance
C. Enabled on a VM or physical server and helps plan SmartPools and file system use
D. FSAnalyze queries results from the last InsightIQ run and populates file system reports

Answer: A

Question: 7

An organization has a five-node standard Isilon cluster. Due to regulatory requirements, they need to build a compliance mode cluster using the existing production hardware. How can this be achieved?

A. Perform an in-place upgrade of the standard cluster to a compliance mode cluster
B. SmartFail two of the nodes and use them to build a new compliance mode cluster
C. Add the SmartLock license to the existing cluster and create some compliance mode directories
D. Purchase a new cluster as there is no way to upgrade an existing cluster or reformat nodes

Answer: A

Question: 6

What are sources from which an Isilon cluster can obtain authentication data about a user attempting to access the cluster?

A. LDAP, NIS, and filedb
B. FTP, filedb, and samdb
C. HTTP, LDAP, and samdb
D. NIS+, HTTP, and NIS

Answer: A

Question: 4

A company has an Isilon cluster on which they want to configure dynamic pools. The cluster consists of 5 nodes. The pool will consist of one 1Gbps Ethernet external interface on each of the nodes. Because the address space is limited at the company’s site, they will need to implement dynamic pools using a minimum number of addresses.
If the company puts all interfaces in one pool and sets it to dynamic with round robin failover, how many addresses need to be put into the pool to ensure an even number of IP addresses per node after failover distribution should a node fail?

A. 4
B. 8
C. 15
D. 20

Answer: D

E20-559 | A storage administrator has just configured a newly…

Question: 3

A storage administrator has just configured a newly acquired Isilon cluster. The administrator connected to the console port of Node 1 and created subnets, pools, and two access zones called “Blue” and “Green”. The administrator then created shares in zone “Blue” and is able to access the shares from their Microsoft Windows clients. In addition, the administrator created exports in the “Green” zone and is able to access the exports from their UNIX clients. However, the administrator is unable to SSH into the cluster and login as root. What is a possible cause for this issue?

A. No interfaces exist in the System zone
B. No authentication providers are defined in the “Blue” and “Green” access zones
C. No failover address was configured for the InfiniBand network
D. A local user “root” needs to be created
