Free EMC E20-555 Practice Exam with Questions & Answers | Set: 5

An Isilon customer has two 5-node clusters; one for production and one for disaster recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ on individual schedules. They have shut down their production cluster for scheduled maintenance, failed over to the DR cluster, and are currently operating from the DR site.

Assume both clusters have identical shares, exports, user authentication. In addition, assume the client applications have been stopped and the DNS re-pointed. What is the easiest SyncIQ Policy method to continue operations on production?

Refer to the exhibit.

Your customer has three different clusters. File systems on two of the clusters are at 90% full, and the largest cluster is 10% full. Active data resides on the largest cluster. The customer has five different node types totaling 2PB and 54 nodes. Nodes from left to right are as shown:

1.X200

2.12000X

3.36000X

4.NL108

5.108NL

They have a Smartpool license and believe that tiering data would help free up needed space.

After talking with the customer and explaining the use of SmartPools, how would you recommend optimizing utilization across all of the nodes that the customer owns?

What is a consideration when designing access zones?

Which type of infrastructure does the Isilon scalable appliance connect to on the front-end?

Which SmartConnect policies are used for workloads that have short lived connections such as HTTP and FTP?

A customer plans to deploy N+2:1 protection on a 5-node Isilon cluster. How much capacity will be used to store a 320 KiB file?

Which SyncIQ policy is required if the goal is to have all source data replicated and to retain deleted files?

A customer is making a decision between Isilon and a competitor’s offering. They currently have 100TB of usable capacity and are forecasting 100% growth per year for the next three years, which will require them to lease additional space in their co-located data center. The CFO finds ROI and TCO to be important decision criteria.

Which statement best emphasizes the value of Isilon for this customer?

Your customer has an Isilon cluster with five X400 nodes and four 72NL nodes. A SmartPools policy moves data to the NL nodes after 60 days of inactivity. The customer wants to expand the archive tier by at least 150 TB and would like to manage a single archive pool.

Which nodes should be added to the cluster?

A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified.

Which Isilon SmartLock version should they implement?
