Exam 5: XtremIO Solutions and Design Specialist Exam for Technology Architects

When using an N+2:1 protection policy on a 7-node Isilon cluster, how much capacity will be used to store a 510 KiB file?

What is the minimum size and the maximum size, respectively, of a single pre-Gen 6 node pool?

A customer needs to consolidate 300 TB of home directory servers and shared file systems used by development and test groups. A key requirement is to prevent the systems from consuming all free capacity and impacting home directory content. Which Isilon node configuration should be proposed?

What is used to set permissions for ESRS-managed devices?

What is a characteristic of predefined sets of privileges of OneFS built-in administrator roles?

A customer has eight X400 24GB RAM that supports 400 client connections today The customer plans to add 400 more clients in the next few months. They are looking at adding an A-Series node to the cluster to help with client connections. Before they start adding client connections, what hardware change do you recommend?

What should be avoided when designing snapshot schedules?

Your customer has an Isilon Gen 6 cluster with eight H400 nodes. During an unexpected power outage some of the nodes go offline simultaneously. How many nodes need to remain up and communicating over the backend network to maintain a quorum in the cluster and still enable write access to the OneFS file system?

A customer is considering moving their NAS data over to Isilon systems. They want to know what limitations Isilon has regarding snapshot on the directory level. What explanation can be provided to the customer?

What is the best case performance for Backup Accelerator when backing up to LTO-4 or LTO-5 drives?

An architect is designing a solution for a new customer. The customer is going to use the cluster to store a large number of files that will be accessed by many users. What IO optimization should be used and what kind of prefetching will take place?

A customer configures a file pool policy to write data to tier 2 on the Isilon cluster. This is in addition to the 30 policies already created. Later in the week they check the file placement and see that it has not been written to the correct tire. What could be the problem?

A customer has a requirement for a new solution to handle their growing storage requirements. The solution should have the ability to cover storage needs for the next three years. The environment consists of 100 TBs of file system data spread across five file systems. On average, the file systems grow 1 TB a month. In addition, they have a large VMware cluster supporting 200 VMs and a highly transactional database. The customer wants the solution to offer good performance, scalability, manageability, and be cost-effective. The sales team is looking to you to recommend a solution. Which recommendation will meet the customer's requirements?

What is the sector size of an Isilon 8 TB drive?

An Isilon customer has set up a replication policy between a primary cluster and a secondary cluster. After the initial synchronization of the clusters, the primary cluster starts to display some issues. The customer initiates a failover operation between the two clusters. During the failover, the primary cluster becomes fully operational again. The customer wants to stop the failover operation between the two clusters. What is the best way to stop the failover operation and continue using the primary cluster?

A customer has two Isilon clusters in an Active-Passive setup. The customer has latency sensitive media editing workflows. Most of the media editing work occurs prior to broadcasting between 7:00-8:00, 11:00-12:00, 17:00-18:00 and 19:00-20:00. What should be recommended to minimize the risk of including latency to the client workflow?

You are working with a healthcare company that is interested in replacing all the backend storage for their PACS system. In general, how should the solution be presented to the customer?

A customer is considering the use of RBAC to centrally administer user accounts that can log into multiple Isilon clusters. What is a potential capability for the customer?

Which part of the XtremIO architecture do host ports use to access an XtremIO volume?

A customer has a cluster consisting of six H500 nodes (in one full chassis and one half populated chassis) and four A200 nodes (in one full chassis). The customer wants to expand their A200 nodes. What is the minimum number of A200 nodes and chassis the customer can add to the cluster?
