EMC EMCSA E20-559 Questions & Answers

• Question 71:

  A storage administrator is migrating existing Microsoft Windows file data to an Isilon cluster. The administrator discovered that two servers are using the same share name in the environment. Which access zone feature will help in implementing this migration?

  A. Each SMB share can be represented with a unique name

  B. Each NFS export can be represented with a unique name

  C. Each access zone will contain all available SMB shares by default

  D. Each access zone will contain all available authentication providers by default

  Correct Answer: A

• Question 72:

  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

  Correct Answer: A

• Question 73:

  Refer to the Exhibit.

  

  A storage administrator has an Isilon cluster with the following:

  Five S210 nodes Eight X200 nodes Eight NL400 nodes

  The cluster default protection level is set to N+2n and the administrator has configured the listed file pool policies. A video capture station saves a new file to /ifs/content/project as intro.mov.

  Which node pool is the intro.mov file written to and which protection level is applied?

  A. NL400_Pool at N+3n protection

  B. S210 _Pool at N+2n protection

  C. X200_Pool at N+2n protection

  D. X200_Pool at N+3n protection

  Correct Answer: B

• Question 74:

  In a three-node Isilon cluster using N+1n data protection, a single 128 KB file is written. How are the stripe units distributed over the nodes?

  A. Node 1: 64 KB stripe unit Node 2: 64 KB mirror Node 3: 64 KB FEC

  B. Node 1: 64 KB stripe unit Node 2: 64 KB stripe unit Node 3: 64 KB FEC

  C. Node 1: 128 KB stripe unit Node 2: 128 KB FEC

  D. Node 1: 128 KB stripe unit Node 2: 128 KB mirror Node 3: 128 KB FEC

  Correct Answer: C

• Question 75:

  What effect does enabling GNA on an Isilon node pool have for SSDs?

  A. Allows node pools without SSDs to use SSDs in other node pools for metadata read acceleration

  B. Allows SSDs in the same node pool as the data to be used for metadata read acceleration

  C. Allows SSDs in all node pools to be used as L3 cache and shared between node pools

  D. Enables cluster-wide read/write metadata acceleration utilizing all SSDs

  Correct Answer: A

• Question 76:

  What can be modified in the subnet settings on an Isilon cluster?

  A. VLAN ID

• Question 77:

  Which interface on an Isilon cluster represents an aggregation of interfaces ext3 and ext4?

  A. ext-agg2

  B. ext-agg

  C. lagg2

  D. cxgb0

  Correct Answer: A

• Question 78:

  A storage administrator needs to create a file pool policy to move files that have not been changed in over two months to their archive tier. The Tiers of nodes with faster and slower node pools already exist. Which file matching criterion should be used to meet this requirement?

  A. atime is older than 2 months ago

  B. birthtime is older than 2 months ago

  C. ctime is older than 2 months ago

  D. mtime is older than 2 months ago

  Correct Answer: D

• Question 79:

  What is required to enable Secure NFS on an Isilon cluster?

  A. Services for NFS must be configured in the AD environment

  B. LDAP must be configured in the system access zone

  C. NFS access must use static address pools

  D. Cluster must be configured to use NTP

  Correct Answer: A

• Question 80:

  What will occur when an Isilon node pool is below the recommended protection level?

  A. CELOG will generate an underprotected event

  B. File will be striped to an additional drive

  C. File will be mirrored

  D. An additional copy of the metadata will be stored on the SSD drives

  Correct Answer: A
