Dell EMC Isilon Solutions and Design Specialist for Technology Architects E20-555 Exam Questions

Where is caching for disk blocks staged on an Isilon node?

What is the overhead impact on the physical capacity when configuring data protection at +2:1 on a 6-node Isilon cluster?

Which type of data is stored in Endurant Cache of an Isilon node?

A customer created eight SyncIQ policies on a 6-node Isilon cluster. The policies all start at midnight. The customer is experiencing issues where several jobs are paused while others continue to run. This is delaying the overall replication of data.

What is the most likely reason for the pausing of some of the SyncIQ jobs?

-- Exhibit --

We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process dat

a. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.

-- Exhibit --

Before making any changes, the customer would like a graphical presentation of their existing array performance to present to management.

What is the best tool to gather this information?

A customer has two data centers (Site A and Site B) and in each data center there is an Isilon cluster. They are replicating data between the sites using SyncIQ.

You have been reviewing their disaster recovery plan and found the following:

* The policies specify that SyncIQ runs a replication job every four hours and that the job finishes within one hour.

* Three additional hours will be needed to get servers and the network redirected to work from Site B.

What is the Recovery Point Objective in this plan?

A customer has 10 files that are each 10 MB in size. They created two clones of each file on their source cluster. They now want to use SyncIQ to replicate the original files and the cloned files to a target cluster.

Excluding protection overhead, how much disk space will the files use on the target cluster?
