EMC E20-555 Actual Free Exam Questions & Community Discussion

Which Isilon OneFS job, that runs manually, is responsible for examining the entire file system for inconsistencies?

Three jobs are running, all with a priority of 5. A new job with a priority of 6 needs to be run. What happens?

An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth.
Which tool would allow the customer to forecast capacity requirements?

A customer is trying to get Isilon SyncIQ to run on the two clusters they just purchased. However, they are experiencing some problems. They have asked you to explain how the SyncIQ licensing works.
What information can be provided to the customer?

What is the correct order of steps taken during the file striping process?

Which Isilon tool can be run from the cluster to display Isilon statistics such as CPU activity?

An Isilon customer experienced a node failure. The failure requires that the affected node be permanently removed from the cluster. What will occur in the cluster upon failure of the node?

A system administrator has identified a problem on the cluster and has opened a service request on support.emc.com. They initiate isi_gather_info but it is taking a long time to complete.
What can they do to speed up the completion of isi_gather_info for the next run?

A company needs the ability to separate administrative rights from data access rights. Which Isilon feature enables this functionality?

What does Isilon OneFS use to re-write data when a disk read fails?

Your customer's site uses an old X-Series cluster, and they are interested in consolidating their two primary workflows. iostat shows that one of the applications is sensitive to latency, while isi statistics indicates sensitivity to disk response times. There are approximately 1000 users accessing 70 TB of file data.
Which node type would you recommend?

Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer's environment.
The customer's current Isilon clusters are as follows:
"Cust" (12 x 12000X) serves as upload media storage for different tenants.
"Working" (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
"Archive" (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization.
The requirements for this solution include:
* Better ROI and TCO
* Maintain same performance with possible improvements
* Renew HW/SW and get inclusive support
* Limit migrations
* Reduce space, power, cooling consumption
* Get new feature sets
* If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections)
* Segregate tenant shares from other tenants
* Expand up to 1PB of total storage
Which licenses need to be defined for the solution to perform optimally?

A company currently has multiple fileservers to provide home directories for its employees. Each department has a separate fileserver. Most corporate users are on Windows clients and utilize Active Directory, except for the Engineering department, which uses Linux and NIS for authentication. The company is looking for a solution with minimal administrative overhead and a single namespace for the home directories.
What is the recommended solution that will meet this company's requirements?

There is a requirement to use dynamic link aggregation to maximize throughput and resiliency on a new Isilon cluster servicing SMB and NFS dat a. What is the recommended configuration for the physical network interfaces?
