What is the recommended method when cabling an Isilon cluster with dual InfiniBand switches?
- A . All int-a InfiniBand switch ports should be connected to one switch and all int-b ports should be cabled to the second switch.
- B . All internal switch ports on odd-numbered nodes should be attached to switch one and all even numbered nodes should be cabled to switch two.
- C . All int-a switch ports should be cabled to the top row of switch ports on switch one and all int-b ports should be cabled to the bottom row of ports of switch one. Once switch one is full, continue cabling on switch two.
- D . It does not matter which switch ports are used. Any internal switch port can be cabled to either of the InfiniBand switches.
How many Isilon Job Engine v2.0 components will be present on a single node?
- A . One director
- B . Two managers per job
- C . Two workers per task
- D . Three coordinators
In a Dell EMC Isilon SyncIQ policy, what is a feature of the “synchronize” replication type?
- A . Protects from file deletion on the source and target
- B . Retains deleted source data on the target
- C . Protects the source cluster data
- D . Includes the file filter criteria
Where is an Isilon Gen 6 node boot drive located?
- A . On the cache SSD drive at the back of the node
- B . On the mirrored journal drive
- C . On the node’s data drives
- D . On the bootflash drive inside the node
What information is displayed by the isi_hw_status command?
- A . Hardware components and selected statistics
- B . Health status of both NVRAM batteries
- C . Subnet and pool membership for the interfaces
- D . Status of drives in the node
A systems administrator has an Isilon cluster with three X410 nodes in their environment. The default protection setting is 2d:1n at the node pool level. Billions of very small image files, less than 50 KB size, are stored on the cluster.
Recently, the administrator has seen an issue where the cluster’s used capacity is getting full. However, the cumulative size of the files copied appears to be less.
What is a possible reason for the storage usage level?
- A . Small files are stored with 4x mirror protection and consuming more capacity
- B . Small files are stored with 2x mirror protection and consuming more capacity
- C . Metadata of billions of files is consuming most of the capacity
- D . Small files are spread across all nodes and consuming more capacity
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
On the Isilon cluster CLI, which command will display the most active nodes every two seconds, from highest to lowest?
- A . isi statistics system –top –nodes –interval=2
- B . isi alert list –newest=2 –nodes=all
- C . isi devices -a status -d 2
- D . isi_for_array -s isi status
Where is the boot drive located on a Dell PowerScale Gen 6 node?
- A . Cache SSD at the back of the node
- B . Bootflash drive inside the node
- C . Data drives of the node
- D . Mirrored journal drive
Which protocols are access zone aware in OneFS 7.2?
- A . SMB and NFS
- B . SMB and FTP
- C . NFS and HTTP
- D . FTP and NFS
